前端界面与后台功能对接

from frame.myQLabel import PaintArea

2.后端代码由我们新建，frame\seekJJ.py

导入本界面

from ui.SeekJJ import Ui_MainWindow

然后对里面的button函数的书写构造。线程类和函数类。

class UploadThread(QThread):sigout = pyqtSignal(float)def __init__(self):super().__init__()self.nativePath = ''self.uploadPath = ''def run(self):n = 0fileLength = len(os.listdir(self.nativePath)) - 1for i in os.listdir(self.nativePath):print(self.nativePath+i)sftp.put(self.nativePath + i, self.uploadPath + i)self.sigout.emit((n/fileLength)*100)n += 1

记得这段代码：调用界面的，下面会说到。 def __init__(self, parent=None):函数初始化各个参数用的。

    def __init__(self, parent=None):super().__init__(parent)  # 调用父类构造函数，创建窗体self.ui = Ui_MainWindow()  # 创建UI对象

界面中的相关按键的函数实现。

在新界面中的

class SeeJJ(QMainWindow):类

表示这是个新窗口类 SeekJJ.show()函数就是打开这个界面的

class SeekJJ(QMainWindow):def resizeEvent(self, e):try:img = QPixmap(self.ct_file)width = self.ui.ct_img.width()height = self.ui.ct_img.height()if img is None:returnif width > height:small =

if __name__ == "__main__":  # 用于当前窗体测试app = QApplication(sys.argv)  # 创建GUI应用程序form = SeekJJ()  # 创建窗体form.show()sys.exit(app.exec_())

功能1：点击button后，实现界面跳转（不卡顿）

函数：

    def _to_see_jjzb(self):
# 在class SeekJJ(QMainWindow)下，需要self表示当前类self.seeJJ = SeeJJ() # 打开seeJJ界面self.close()         # 当前界面关闭self.seeJJ.show()    # seeJJ界面开启

点击【查看结节坐标界面】，

self.ui.see_jjzb.clicked.connect(lambda: self._to_see_jjzb())

ui.SeekJJ.py界面的相关接口：（在做ui时自动生成的）

        self.see_jjzb = QtWidgets.QPushButton(self.groupBox)self.see_jjzb.setMinimumSize(QtCore.QSize(0, 30))self.see_jjzb.setObjectName("see_jjzb")self.horizontalLayout.addWidget(self.see_jjzb)

.setText函数里面的参数设置了button的名字

        self.see_jjzb.setText(_translate("MainWindow", "查看结节坐标"))

功能2：选择文件路径按钮，并将选择后的路径显示在文本框中。

前端选择CT路径的button的触发事件函数：

    def function(self):self.ui.choose_ct_path.clicked.connect(lambda: self._choose_ct_path())

选择CT路径的触发函数

    def _choose_ct_path(self):try:# 弹出选择文件夹路径的标题栏title名字self.ct_path_text = QFileDialog.getExistingDirectory(None, '请选择CT文件路径')# 如果路径的文本框是空的，清空picture文件夹下的所有文件if self.ct_path_text != "":for i in os.listdir('../picture/'):os.remove('../picture/' + i)# os.listdir()返回指定路径下的文件和文件夹列表。self.picSize = len(os.listdir(self.ct_path_text))for i, id in enumerate(os.listdir(self.ct_path_text)):RefDs = sitk.ReadImage(self.ct_path_text + '/' + id)data = sitk.GetArrayFromImage(RefDs)[0]# -1000到400,的CT影像转化为256个灰度值，1400除以256等于5.46875data = (np.minimum(np.maximum(data, -1000), 400) + 1000)/5.46875
# 写入data，[int(cv2.IMWRITE_JPEG_QUALITY), 100]的意思是将画质调整为最好的100cv2.imwrite('../picture/%s.jpg' % (self.picSize-i), data, [int(cv2.IMWRITE_JPEG_QUALITY), 100])else:return# 将路径的名字读入到文本框中self.ui.ct_path.setText(self.ct_path_text)
# 设置多线程上传文件夹的路径self.upload_thread.nativePath = self.ct_path_text + '/'
# 设置【调整层数】滑动条的最大值和最小值self.ui.layer_slider.setMaximum(self.picSize-1)self.ui.layer_slider.setMinimum(0)
# 初始化当前层数，1/nself.ui.now_layers_label.setText('当前层数：1/' + str(self.picSize))
# 默认将1.jpg作为主界面的显示self.ct_file = "../picture/1.jpg"img = QtGui.QPixmap(self.ct_file)
# 显示图片，保持横纵比img = img.scaled(self.ct_img_small_size, self.ct_img_small_size, Qt.KeepAspectRatio)self.ui.ct_img.setPixmap(img)
# 打印报错信息except Exception as e:print(e)

初始化了主界面的滑动条是1/n，默认将第一幅图像作为显示图像，在滑动进度条的时候，动态改变进度条的层数，动态改变图片的显示。

因此这俩动态变化的功能需要在滑动条函数中写：

前端滑动条的鼠标点击触发事件：

self.ui.layer_slider.valueChanged.connect(self._layer_slider_changed)

滑动条函数：

    def _layer_slider_changed(self, value):
# 判断非空路径if self.ct_path_text == '':return
# 设置显示的图片的路径self.ct_file = "../picture/%d.jpg" % (value+1)
# 继续保持横纵比不变img = QtGui.QPixmap(self.ct_file)img = img.scaled(self.ct_img_small_size, self.ct_img_small_size, Qt.KeepAspectRatio)self.ui.ct_img.setPixmap(img)
# 动态显示当前层数self.ui.now_layers_label.setText('当前层数：' + str(value+1) + '/' + str(self.picSize))

功能3：【上传】按钮，将本地的文件上传到服务器中，实现进度条显示

前端upload_ctbutton组件的鼠标点击触发事件：

self.ui.upload_ct.clicked.connect(lambda: self._upload_ct())

上传函数_upload_ct的具体实现：

    def _upload_ct(self):try:
# 判断路径非空if self.ui.ct_path.text() == '':
# 路径空值时弹出提示框QMessageBox().information(self, '提示', '请选择CT文件路径', QMessageBox.Yes)return
# stdin, stdout, stderr，输入信息，命令行输出信息，输出错误信息，需要引入paramiko的sshstdin, stdout, stderr = ssh.exec_command('cd ' + self.serverWorkSpace + ';python clearCT.py')
# 打印命令行产生的输出和错误信息print(stdout.read())print(stderr.read())
# upload_thread多线程上传self.upload_thread.start()
# 上传进度条事件self.upload_thread.sigout.connect(self._change_progress)except Exception as e:print(e)

关于多线程上传的，在此一并说了：

重写run函数，线程启动的时候会直接执行run（）方法，我们在此处进行重写，这样线程启动的时候会执行我们写的这个run方法。
我们使用 self.upload_thread.start()方法这个来启用线程，但是线程的启用会先来找run方法

class UploadThread(QThread):
# 设置多线程类
# 刚才看到的sigout在此设置的，pyqtSignal(float)是信号的传递，操作系统中的哲学家就餐问题的一个简
# 化，防止进程死锁，以float类型的参数进行传递sigout = pyqtSignal(float)# 初始化，设置常参数def __init__(self):
# 继承 __init__ 类中的所有super().__init__()
# 在继承的基础上添加初始化的路径参数self.nativePath = ''self.uploadPath = ''# 重写run函数，线程启动的时候会直接执行run（）方法，我们在此处进行重写，这样线程启动的 时候会执行我# 们写的这个run方法。
# 我们使用 self.upload_thread.start()。这个来启用线程，但是线程的启用会先来找run方法def run(self):n = 0fileLength = len(os.listdir(self.nativePath)) - 1for i in os.listdir(self.nativePath):print(self.nativePath+i)
# 将本地文件上传到服务器nativePath + i是本地路径+i文件的意思sftp.put(self.nativePath + i, self.uploadPath + i)
# 发送信号self.sigout.emit((n/fileLength)*100)n += 1

self.sigout.emit((n/fileLength)*100)，上传到100%

前端界面的上传进度条的进度百分比的显示功能函数的书写：

    def _change_progress(self, value):
# 进度条传入的value值self.ui.upload_progressBar.setValue(value)print(value)if value == 100:
# 弹出框显示上传完成QMessageBox().information(self, '提示', "上传完成", QMessageBox.Yes)

功能4：在lable区域读出CT图像后，用鼠标事件，添加绘图功能，绘制十字坐标线。

from PyQt5 import QtGui, QtCore
from PyQt5.QtCore import QRect, QPoint, Qt
from PyQt5.QtGui import QPen, QBrush, QPainter, QPixmap
from PyQt5.QtWidgets import QLabel
# 导入依赖包# 定义绘画类，这个地方注意一下，因为是（QLabel）参数，因此绘画的都是QLabel区域，坐标也是这个里面# 的区域
class PaintArea(QLabel):def __init__(self, parent=None):super().__init__(parent)
# 初始化各个参数
# 设置对其方式，居中对齐 AlignCenterself.setAlignment(QtCore.Qt.AlignCenter)self.markX = 0  # 在图像中的标记self.markY = 0self.ctX = 256  # 对应CT影像中的真实坐标self.ctY = 256self.mark = Falseself.slider = None# 重写绘画事件def paintEvent(self, event):
# 继承绘画类super().paintEvent(event)
# 因为self.mark = False，因此初始状态不执行绘画事件，鼠标点击后将mark改为trueif self.mark:painter = QPainter(self)
# setPen（self，color）方法，(0, 0, 255)设置为蓝色，1为线段的粗细程度为1painter.setPen(QtGui.QPen(QtGui.QColor(0, 0, 255), 1))
# .drawLine（self，l）方法画线，这都是建立在self.mark = True的基础之上的painter.drawLine(self.markX, 0, self.markX, self.height())painter.drawLine(0, self.markY, self.width(), self.markY)def wheelEvent(self, e):if e.angleDelta().y() < 0:# 放大图片if self.slider is not None:self.slider.setValue(self.slider.value()+1)elif e.angleDelta().y() > 0:# 缩小图片if self.slider is not None:self.slider.setValue(self.slider.value()-1)# 重写鼠标点击事件def mousePressEvent(self, event):
# 获取鼠标点击的横纵坐标self.markX = event.x()self.markY = event.y()self.mark2ct()self.mark = True
# repaint方法重画界面，算是刷新self.repaint()# biaoji zuobiao def mark2ct(self):if self.width() > self.height():
# 点击鼠标事件，标记坐标
# 这个地方需要注意，CT是512*512的，所以初始化ctx应该是（256，256）位中间点的坐标
# ctX是指图片的ctx的坐标，和lable没关系
# ctx指的是坐标在长＞高的时候，x的相对位置，{x-[(b-a)/2]}/a*512self.ctX = (self.markX - (self.width() - self.height())/2)/self.height()*512self.ctY = self.markY/self.height()*512else:self.ctX = self.markX/self.width()*512self.ctY = (self.markY-(self.height()-self.width())/2)/self.width()*512
# 如果已经有坐标，拖动窗口的大小，鼠标坐标自适应改变，不会错位def ct2mark(self):if self.width() > self.height():self.markX = (self.width()-self.height())/2+(self.ctX/512)*self.height()self.markY = (self.ctY/512)*self.height()else:self.markX = (self.ctX/512)*self.width()self.markY = (self.height()-self.width())/2+(self.ctY/512)*self.width()
# 自适应改完重新画坐标点self.repaint()def setCtXY(self, x, y):self.ctX = xself.ctY = yself.mark = Trueself.ct2mark()

功能5. 从服务器下载检测结果到本地，seeJJ.py

首先介绍界面以及初始化：

class SeeJJ(QMainWindow):def resizeEvent(self, e):try:img = QPixmap(self.ct_file)width = self.ui.ct_img.width()height = self.ui.ct_img.height()if img is None:returnif width > height:small = heightelse:small = widthself.ct_img_small_size = smallimg = img.scaled(small, small, Qt.KeepAspectRatio, Qt.SmoothTransformation)self.ui.ct_img.setPixmap(QPixmap(''))self.ui.ct_img.setPixmap(img)self.ui.ct_img.ct2mark()except Exception as e:print(e)# 初始化参数def __init__(self, parent=None):super().__init__(parent)  # 调用父类构造函数，创建窗体
# Ui_MainWindow()为SeeJJ.py中的类名self.ui = Ui_MainWindow()  # 创建UI对象self.ui.setupUi(self)  # 构造UI界面self.serverWorkSpace_jiance = 'E:/LYC/lungDetection-V1/'self.serverWorkSpace_fenlei = 'E:/LYC/fenlei/'self.serverPython = 'D:/ProgramData/Anaconda3/envs/G_capsenv/python'self.zb_list = []self.ui.zb_listWidget.addItem('序号          x             y             z')
# 在服务器中的文件保存在'../picture/'路径下，因此要读取本路径下的文件的规模self.picSize = len(os.listdir('../picture/'))
# 滑动块的最大值self.ui.layer_ajust_slider.setMaximum(self.picSize-1)self.ui.layer_ajust_slider.setMinimum(0)
# 初始化滑块的值1/nself.ui.now_layer_label.setText('当前层数：1/' + str(self.picSize))# self.ct_img_small_size = 512  # ct影像尺寸标准，以宽高小者为准
# 宽度 = ct_img的宽度width = self.ui.ct_img.width()height = self.ui.ct_img.height()
# 滑块？将ui里面的滑块赋值给这个类里面的滑块self.ui.ct_img.slider = self.ui.layer_ajust_sliderif width > height:self.ct_img_small_size = heightelse:self.ct_img_small_size = width
# 记录图片层数，初始化界面显示为第一层self.ct_file = '../picture/1.jpg'  # 记录当前ct层数的图片文件img = QPixmap(self.ct_file)
# img.scaled(self，width，height，aspectRatioMode，TransformMode）方法
# 最小值作为边长的正方形，保持横纵比，光滑变换img = img.scaled(self.ct_img_small_size, self.ct_img_small_size, Qt.KeepAspectRatio, Qt.SmoothTransformation)self.ui.ct_img.setPixmap(img)
# 执行lambda函数集合self.function()

从服务器下载文件到本地：

# 定义组件的接口函数def function(self):self.ui.down_load.clicked.connect(lambda: self._down_load_zb())# 对接口函数 _down_load_zb() 的实现def _down_load_zb(self):try:# 从服务器将2020NewData.xlsx文件下载到本地的data文件夹下sftp.get(self.serverWorkSpace_jiance + '2020NewData.xlsx', '../data/new data.xlsx')
# 完事以后，弹出成功界面QMessageBox().information(self, '提示', "成功下载到本地", QMessageBox.Yes)except Exception as e:print(e)

关于 sftp 方法，用的是 paramiko 函数库进行实现，关于这个服务器功能单独写一个connect.py文件实现与服务器的连接：

import paramikotransport = paramiko.Transport(('服务器ip', 端口号))
# 建立连接
transport.connect(username='Fizz', password='密码')
# 将sshclient的对象的transport指定为以上的transport
ssh = paramiko.SSHClient()
ssh._transport = transport
# sftp在此处赋值
sftp = paramiko.SFTPClient.from_transport(transport)

用这么一句代码：sftp.get(self.serverWorkSpace_jiance + '2020NewData.xlsx', '../data/new data.xlsx')

即可以实现文件从服务器的下载。

功能6：实现菜单栏的各个跳转功能

    def processtrigger(self, action):if action.text() == '退出':self.close()elif action.text() == '系统首页':
# Index.py文件中的Index（）类赋值给本类的self.indexself.index = Index.Index()self.index.show()self.close()elif action.text() == '裁剪肺结节':self.seeJJ = SeeJJ.SeeJJ()self.seeJJ.show()self.close()elif action.text() == '肺结节影像良恶性诊断':
# from frame import ClassifyJJself.classifyJJ = ClassifyJJ.ClassifyJJ()self.classifyJJ.show()self.close()

功能7：python与excle表格交互：读取信息 + python读写操作

鼠标点击button事件：

self.ui.read_zb.clicked.connect(lambda: self._read_zb())

左侧坐标显示栏的函数实现：

    def _read_zb(self):
# 初始化清空列表self.ui.zb_listWidget.clear()self.zb_list.clear()self.ui.zb_listWidget.addItem('序号          x             y             z')
# from openpyxl import load_workbook；加载excle的方法，读入wb = load_workbook('../data/new data.xlsx')sheet = wb.activei = 2while True:
# 读入M列的值，空值则停content = sheet["M%d" % i].valueif content is None or content == "":break
# 从左侧的第一个元素，到倒数第一个元素。content = content[1:-1]
# 逗号分隔开，这样就把坐标中的三个数取出来了index = content.split(",")x, y, z = index[0], index[1], index[2]self.zb_list.append((index[0], index[1], index[2]))self.ui.zb_listWidget.addItem(' ' + str(i-1) + '          ' + x + '          ' + y + '          ' + z)i += 1

Classfy.py文件。分类检测

本处附带服务器代码，关于python写入Excel的方法：

from openpyxl import Workbook
import cv2def write_zb_excel(indexList,jjdx):wb = Workbook()sheet = wb.activesheet.title='Sheet1'sheet['A1'].value = '影像号'sheet['M1'].value = '坐标'sheet['N1'].value = '结节大小'sheet['O1'].value = '病理类型'sheet['AF1'].value = '年份'sheet["A2"].value = '10203040'img = cv2.imread('E:/LYC/lungDetection-V1/detection/savejpg2/0006/0.jpg')w, h = img.shape[0], img.shape[1]f = open(r'..\detection\extendbox.txt', 'r')extendbox = f.readlines()startX = int(extendbox[0])startY = int(extendbox[2])startZ = int(extendbox[4])f.close()f = open(r'..\detection\spacing.txt', 'r')space = f.readline()space = space.split(',')spaceZ = float(space[0])spaceXY = float(space[1])f.close()for i, index in enumerate(indexList):x, y, z = index[0], index[1], index[2]x = round((x + startX) / spaceXY)y = round((y + startY) / spaceXY)z = round((z + startZ + 1) / spaceZ)content = '(' + str(x) + ',' + str(y) + ',' + str(z) + ')'sheet["M%d" % (i + 2)].value = contentsheet["O%d" % (i + 2)].value = 2sheet["AF%d" % (i + 2)].value = 2020for i,jj in enumerate(jjdx):sheet["N%d" % (i + 2)].value = jjwb.save('../2020NewData.xlsx')

如下，jjdx（结节大小）为一列表[1,2,3,1,1]之类似，enumerate函数的作用是一个数一个数的去拿；第二行是存在N列的每一行中。

    for i,jj in enumerate(jjdx):sheet["N%d" % (i + 2)].value = jj

功能8：从服务器下载文件到本地

self.ui.download_jj_file.clicked.connect(lambda: self._download_jj_file())

函数实现：

    def _download_jj_file(self):try:npyList = os.listdir('../npy')for npy in npyList:os.remove('../npy/' + npy)fileArray = sftp.listdir(self.serverWorkSpace + 'prework/dataset17-20_cf/test30')for file in fileArray:sftp.get(self.serverWorkSpace + 'prework/dataset17-20_cf/test30/' + file, '../npy/' + file)QMessageBox().information(self, '提示', "成功下载到本地", QMessageBox.Yes)except Exception as e:print(e)

功能9：从服务器下载结节文件，列表读取本地文件

点击【读取结节文件】按钮，实现列表框中读取。

    def _read_jj(self):
# 清空列表self.ui.jj_listWidget.clear()jjList = os.listdir('../npy/')
# 加载文件for jj in jjList:self.ui.jj_listWidget.addItem(jj)

鼠标点击事件，实现界面的动态变化。

    def _jj_listWidget_clicked(self, item):try:if item is None:returnfile = item.text()# 本段显示结节图像path = '../npy/' + fileimage_data = np.load(path)
# //取整，/浮点数image_data = image_data[image_data.shape[0] // 2]###image_data = (np.minimum(np.maximum(image_data, -1000), 400) + 1000)/5.46875img_pil = Image.fromarray(np.uint8(image_data)).resize((150, 150))self.ui.jj_img.setPixmap(img_pil.toqpixmap())# 根据文件后缀数字确定序号，获取xlsx文件中的坐标
# 正则表达式找 10203040-1.npy之类的文件，findallid = re.findall(r'.*?-(.*?).npy', file)[0]index = self.zbList[int(id)]index = index[1:-1]print(index)index = index.split(',')# 在结节部分显示坐标self.ui.jj_zb_label.setText('坐标： X:%s  Y:%s  Z:%s' % (index[0], index[1], index[2]))# 在CT中标记结节self.ui.ct_img.setCtXY(int(index[0]), int(index[1]))# ct切换到相应页面self.ui.layer_ajust_slider.setValue(int(index[2]))self.ct_file = '../picture/' + index[2] + '.jpg'img = QPixmap(self.ct_file)img = img.scaled(self.ct_img_small_size, self.ct_img_small_size, Qt.KeepAspectRatio,Qt.SmoothTransformation)self.ui.ct_img.setPixmap(img)if len(self.resList) == 0:returnresult = list(map(float, self.resList[int(id)]))result = np.exp(result)/np.sum(np.exp(result), axis=0)
# 显示百分比self.ui.result_lx_progressBar.setValue(float(result[0])*100)self.ui.result_la_progressBar.setValue(float(result[1])*100)self.ui.result_xa_progressBar.setValue(float(result[2])*100)except Exception as e:print(e)

功能10 ：添加【软件说明】界面，添加新界面，并将新界面的button功能实现

1.在UI界面【帮助】下添加【软件使用说明】的QAction，添加方法为，先点击type here，输入wohenshuai

右侧的QAction属性栏如下：

调整frame格式：

选中要编辑的frame模块，右键stylesheet，复制里面的格式代码，到新的界面粘贴

参考里面的代码，可写更多样式。

我在【帮助】下添加的是【软件使用说明】，QAction是rjsm

    def processtrigger(self, action):if action.text() == '退出':self.close()elif action.text() == '系统首页':self.index = Index.Index()self.index.show()self.close()elif action.text() == '肺结节检测':self.seekJJ = SeekJJ.SeekJJ()self.seekJJ.show()self.close()elif action.text() == '肺结节影像良恶性诊断':self.classifyJJ = ClassifyJJ.ClassifyJJ()self.classifyJJ.show()self.close()elif action.text() == '软件使用说明':self.rjsm = gnsm.Gnsm()self.rjsm.show()

弹出界面不关闭

然后

from frame import gnsm

即可。self.rjsm为新命名而已，不指向其他东西；gnsm.Gnsm()指的是import的gnsm界面下的Gnsm类

添加新界面之后，如果界面中有函数，要初始化函数，并且执行之。这点十分重要，我将在下面举例说明！！！！！！！！

添加完一个软件使用说明以后，在其他界面进行添加就比较容易了。

第一步：修改ui界面，在ui界面添加【帮助】-【软件使用说明】

第二步：添加elif功能

第三步：

from frame import gnsm

功能11：生成报告。python将信息写入word文档。

关于word的操作，大概可以如下：

    def _submit(self):
# 判断信息完整性if self.ui.patient_name.text() == ''\or self.ui.patient_id.text() == ''\or self.ui.ct_describe_textEdit.toPlainText() == ''\or self.ui.doctor_advice_textEdit.toPlainText() == '':
# 弹出未完善的提示信息QMessageBox().information(self, '提示', '请完善信息', QMessageBox.Ok)return
# 选择保存路径的选择框save_path_text = QFileDialog.getExistingDirectory(None, '请选择报告保存路径')
# 判断保存路径非空if save_path_text == '':QMessageBox().information(self, '提示', '未选择保存路径', QMessageBox.Ok)return
# 读入word模板doc = docx.Document('../word/model.docx')  # 读取模板
# 写入信息doc.paragraphs[1].text = '病历号：%s             姓名：%s                 检查时间：%s' % \(self.ui.patient_id.text(), self.ui.patient_name.text(), self.ui.diagnose_date.text())# 第三段添加图片，选中的肺结节图片run = doc.paragraphs[3].add_run()for file in os.listdir('../npy_img/'):run.add_picture('../npy_img/' + file)run = doc.paragraphs[3].add_run('  ')
# 将文档中的文字信息写入word的表格中doc.tables[0].rows[0].cells[0].text = self.ui.ct_describe_textEdit.toPlainText()doc.tables[1].rows[0].cells[0].text = self.ui.doctor_advice_textEdit.toPlainText()
# 将写好的文档保存在本地的绝对路径中，命名使用患者id命名doc.save(save_path_text + '/' + self.ui.patient_id.text() + '.docx')  # 要写绝对路径QMessageBox().information(self, '提示', '成功生成报告', QMessageBox.Ok)

功能12：选中结节和取消选中的样式改变，选中后及时保存选中文件

点击左侧的npy文件，点击【写入检测报告】，选中结节，将结节图片文件保存起来；

点击选中的结节，点击【移除检测报告】，取消选中，并将保存的结节文件删除掉。

具体的

self.ui.put_jj_in_report.clicked.connect(lambda: self._put_jj_in_report())

的实现如下：

    def _put_jj_in_report(self):
# 我们规定选的结节个数不超过6个try:if self.put_npy_num >= 6:QMessageBox().information(self, '提示', '写入结节数不能超过6个', QMessageBox.Ok)return
# 选中结节后row = self.ui.jj_listWidget.currentRow()
# 设置选中时的颜色，设置选中时的icon图标self.ui.jj_listWidget.item(row).setBackground(QColor(190, 217, 238))self.ui.jj_listWidget.item(row).setIcon(QIcon('../image/t7.ico'))
# 并将本结节文件保存起来，生成报告的时候直接使用，用npy文件的名字命名jpgself.ui.jj_img.pixmap().save('../npy_img/%s.jpg' % self.ui.jj_listWidget.item(row).text())self.put_npy_num += 1except Exception as e:print(e)

移除结节文件的函数实现：

    def _remove_jj_from_report(self):try:
# 选中本行row = self.ui.jj_listWidget.currentRow()
# 设置颜色，图标设置为空值self.ui.jj_listWidget.item(row).setBackground(QColor(255, 255, 255))self.ui.jj_listWidget.item(row).setIcon(QIcon(''))
# 删除保存的文件os.remove('../npy_img/%s.jpg' % self.ui.jj_listWidget.item(row).text())self.put_npy_num -= 1except Exception as e:print(e)

这俩功能，将结果显示出来，读取坐标值。不好解释，不做解释。

    def _jj_listWidget_clicked(self, item):try:if item is None:returnfile = item.text()# 显示结节图像path = '../npy/' + fileimage_data = np.load(path)image_data = image_data[image_data.shape[0] // 2]###image_data = (np.minimum(np.maximum(image_data, -1000), 400) + 1000)/5.46875img_pil = Image.fromarray(np.uint8(image_data)).resize((150, 150))self.ui.jj_img.setPixmap(img_pil.toqpixmap())# 根据文件后缀数字确定序号，获取xlsx文件中的坐标id = re.findall(r'.*?-(.*?).npy', file)[0]index = self.zbList[int(id)]index = index[1:-1]print(index)index = index.split(',')# 在结节部分显示坐标self.ui.zb_info_label.setText('坐标： X:%s  Y:%s  Z:%s' % (index[0], index[1], index[2]))if len(self.resList) == 0:returnresult = list(map(float, self.resList[int(id)]))result = np.exp(result)/np.sum(np.exp(result), axis=0)self.ui.res_lx_progressBar.setValue(float(result[0])*100)self.ui.res_la_progressBar.setValue(float(result[1])*100)self.ui.res_xa_progressBar.setValue(float(result[2])*100)except Exception as e:print(e)def _read_jj(self):# 读取已经下载的坐标值self.zbList.clear()wb = load_workbook('../data/new data.xlsx')sheet = wb.activei = 2while True:content = sheet["M%d" % i].valueif content is None or content == "":breakself.zbList.append(content)i += 1# 读取已经下载的识别结果self.resList.clear()resNum = len(os.listdir('../result'))for i in range(resNum):f = open('../result/tes_prob_batch' + str(i) + '.txt')batches = f.readlines()for batch in batches:batch = batch[0:-2]  # 去除换行符number = batch.split(' ')self.resList.append((number[1][0:8], number[2][0:8], number[3][0:8]))f.close()# 将结节文件显示在列表self.ui.jj_listWidget.clear()jjList = os.listdir('../npy/')for jj in jjList:self.ui.jj_listWidget.addItem(jj)

功能13：登录界面的跳转（project-hjq）

    def yanzheng(self):self.n=0
# 账号密码存放在同一级目录的11.txt下f=open('./11.txt')ma=self.username.text()+'.'+self.password.text()for i in f:
# 判定登陆成功if i[:-1]==ma:QMessageBox.information(self, " ", "登录成功！", QMessageBox.Yes)
# 登陆成功后打开新界面 mainimport mainself.hide()# self.form.hide()  # 如果没有self.form.show()这一句，关闭Demo1界面后就会关闭程序
# main界面打开self.ex = main.Example()self.ex.show()self.n=1if self.n==0:
# 这里将三种报错信息放在了一起，报错信息弹框是一样的，不一样的地方是图标不一样。QMessageBox.information(self, " ", "登录成功！", QMessageBox.Yes)QMessageBox.critical(self, " ", "密码错误！", QMessageBox.Yes)QMessageBox.warning(self, " ", "查无此人！", QMessageBox.Yes)# 记得关闭txtf.close()

功能14：添加新界面，并实现其中的各个功能。

第一步：制作ui界面，并且将ui界面的各个button记录好，然后用 pyuic5 -o 命令转化为py程序。这一步不在赘述

第二步：在后台程序的文件夹（frame）中新建实现本界面以及功能的py文件，

提示：ui文件和第一步生成的界面py文件在ui文件夹下；我要实现的后台程序的py文件在frame文件夹下，因此，我在frame新建的程序yjjc.py引入ui文件即可。

from ui.Yjjc import Ui_MainWindow

然后实现主方法，显示本界面：

if __name__ == "__main__":  # 用于当前窗体测试app = QApplication(sys.argv)  # 创建GUI应用程序form = Yjjc()  # 创建窗体form.show()sys.exit(app.exec_())

这段代码为避免将来忘记，在此解释一下，只需要改 form = Yjjc() 这一句即可，就是声明一个新界面为form，这个Yjjc就是本主界面的类：

这样ui界面的内容就可以显示了

第三步：实现界面中的按键的功能

首先写

def __init__(self, parent=None):

这个函数，继承父类的窗体，固定代码：

    def __init__(self, parent=None):super().__init__(parent)  # 调用父类构造函数，创建窗体self.ui = Ui_MainWindow()  # 创建UI对象self.ui.setupUi(self)  # 构造UI界面

这说明这个界面已经继承了父类的窗体。

继承完窗体，然后找ui界面中的一键检测的按钮的名字。我命名为yjjc

于是，实现这个功能

    def function(self):self.ui.yjjc.clicked.connect(lambda: self._Yjjcsb())

新建一个function类，声明各个组件的对应的函数，在这里一定要注意注意再注意，声明的function函数类必须要初始化！！！

也就是在def __init__ 中添加这么一句代码：

self.function()

这样才可以正常执行，否则不可以！如图：

将用到的初始化的东西全都写在__init__函数中

第四步：写具体的实现函数，就是function中lambda的函数

    def _Yjjcsb(self):try:stdin, stdout, stderr = ssh.exec_command('cd ' + self.serverWorkSpace +'detection/;' + self.serverPython + ' dcm2mhd.py')print(stdout.read())print(stderr.read())QMessageBox().information(self, '提示', "成功生成mhd文件", QMessageBox.Yes)except Exception as e:print(e)

这样就可以了。

以上四步实现的是按钮的功能的具体实现，下面写的是选择文件路径，并将文件上传的路基顺序：

第一步：实现选择文件路径按钮的函数

self.ui.choose_ct_path.clicked.connect(lambda: self._choose_ct_path())

第二步：实现 lambda: self._choose_ct_path() 函数

    def _choose_ct_path(self):try:self.ct_path_text = QFileDialog.getExistingDirectory(None, '请选择CT文件路径')if self.ct_path_text != "":for i in os.listdir('../picture/'):os.remove('../picture/' + i)self.picSize = len(os.listdir(self.ct_path_text))for i, id in enumerate(os.listdir(self.ct_path_text)):data = pydicom.dcmread(self.ct_path_text + '/' + id).pixel_arraydata = (np.minimum(np.maximum(data, 0), 4096)) / 6###plt.imsave('../picture/%s.jpg' % (self.picSize-i),data, cmap='gray', vmin=0, vmax=255)else:returnself.ui.ct_path.setText(self.ct_path_text)self.upload_thread.nativePath = self.ct_path_text + '/'self.ui.layer_slider.setMaximum(self.picSize-1)self.ui.layer_slider.setMinimum(0)self.ui.now_layers_label.setText('当前层数：1/' + str(self.picSize))self.ct_file = "../picture/1.jpg"img = QtGui.QPixmap(self.ct_file)img = img.scaled(self.ct_img_small_size, self.ct_img_small_size, Qt.KeepAspectRatio)self.ui.ct_img.setPixmap(img)except Exception as e:print(e)

这段代码下面的 self.ui.... 属于初始化的参数值

self.ui.ct_path.setText(self.ct_path_text) 指的是显示路径的文本框；

下面这两句：

self.ui.layer_slider.setMaximum(self.picSize-1)self.ui.layer_slider.setMinimum(0)

指的是滑动条的初始化的最大值最小值

ct_path.setText和layer_slider在上图已标注。

接下来要实现上传功能，首先书写上传按钮的实现方法：

    def _upload_ct(self):try:if self.ui.ct_path.text() == '' or self.ct_path_text == '':QMessageBox().information(self, '提示', '请选择CT文件路径', QMessageBox.Yes)# QtWidgets.QMessageBox(QMessageBox.Warning, '提示', '请选择CT文件路径').exec_()returnstdin, stdout, stderr = ssh.exec_command('cd ' + self.serverWorkSpace + ';python clearCT.py')print(stdout.read())print(stderr.read())self.upload_thread.start()self.upload_thread.sigout.connect(self._change_progress)except Exception as e:print(e)

书写上传的进程类

class UploadThread(QThread):sigout = pyqtSignal(float)def __init__(self):super().__init__()self.nativePath = ''self.uploadPath = ''def run(self):n = 0fileLength = len(os.listdir(self.nativePath)) - 1for i in os.listdir(self.nativePath):print(self.nativePath+i)sftp.put(self.nativePath + i, self.uploadPath + i)self.sigout.emit((n/fileLength)*100)n += 1

因为本处的 self.uploadPath = '' 上传路径设置为空值，因此需要在初始化里面设置好上传路径的具体指，否则程序虽然会上传但是却传不到指定路径下。

self.upload_thread.uploadPath = self.serverWorkSpace + 'detection/test_mask/0006/'

一定要记得初始化！！

self.upload_thread = UploadThread()

初始化函数里有这句话才行的。重写了run方法实现上传功能。

上传进度为百分之百的时候，弹窗提示上传完成：

    def _change_progress(self, value):self.ui.upload_progressBar.setValue(value)print(value)if value == 100:QMessageBox().information(self, '提示', "上传完成", QMessageBox.Yes)

另一个功能：实现滑块的拖动

self.ui.layer_slider.valueChanged.connect(self._layer_slider_changed)

实现本函数的方法：

    def _layer_slider_changed(self, value):if self.ct_path_text == '':returnself.ct_file = "../picture/%d.jpg" % (value+1)img = QtGui.QPixmap(self.ct_file)img = img.scaled(self.ct_img_small_size, self.ct_img_small_size, Qt.KeepAspectRatio)self.ui.ct_img.setPixmap(img)self.ui.now_layers_label.setText('当前层数：' + str(value+1) + '/' + str(self.picSize))

鼠标的滑轮实现图片的滚动浏览等会再写

功能15：添加登录界面，账号密码登陆成功实现跳转

在之前的界面基础上，添加新界面。思路比较简单，添加login.py界面即可，使登陆成功后，跳转至index.py。

只需打包login.py即可。

具体实现方法如下：

界面添加上txt文本验证，账号密码在文本中，就登陆成功。否则失败。

至于txt的账号密码内容，可在服务器端实现修改，每次运行下载至本地。

功能16：下拉框选中文字，实现在文本框中自动粘贴的功能。

      # pyqt界面的  ct_discribe和doctor_advice组件点击粘贴事件
self.ui.ct_discribe.currentTextChanged.connect(lambda :self.Clickme_ct())
self.ui.doctor_advice.currentTextChanged.connect(lambda :self.Clickme_doc())

点击将文字粘贴至下拉框中。

    def Clickme_ct(self):print(self.ui.ct_discribe.currentText())ct_dis = self.ui.ct_describe_textEdit.toPlainText()ct_dis += self.ui.ct_discribe.currentText()self.ui.ct_describe_textEdit.setText(ct_dis)print("文字粘贴到CT影像描述文本框")def Clickme_doc(self):print(self.ui.doctor_advice.currentText())doc_adv = self.ui.doctor_advice_textEdit.toPlainText()doc_adv += self.ui.doctor_advice.currentText()self.ui.doctor_advice_textEdit.setText(doc_adv)

功能17：克服桶排序。显示前24个结节。

思路是：桶排序按照字符长度排序的，同一字符同一排序，因此按照len（）方法长度排序即可。

显示前24个结节也比较简单，循环到24，break即可。

    def _read_jj(self):# 读取已经下载的坐标值self.zbList.clear()wb = load_workbook('../data/new data.xlsx')sheet = wb.activei = 2while True:content = sheet["M%d" % i].valueif content is None or content == "":breakself.zbList.append(content)i += 1# 读取已经下载的识别结果self.resList.clear()resNum = len(os.listdir('../result'))for i in range(resNum):f = open('../result/tes_prob_batch' + str(i) + '.txt')batches = f.readlines()for batch in batches:batch = batch[0:-2]  # 去除换行符number = batch.split(' ')self.resList.append((number[1][0:8], number[2][0:8], number[3][0:8]))f.close()# 将结节文件显示在列表self.ui.jj_listWidget.clear()jjList = os.listdir('../npy/')jjList.sort(key=functools.cmp_to_key(self.jj_sort2))i = 0for jj in jjList:# print(jj)# s = jj.split("-")[-1]self.ui.jj_listWidget.addItem(jj)i += 1if i >= 24:break# self.ui.jj_listWidget.setSortingEnabled(True)def jj_sort2(self,x,y):return len(x)-len(y)
