前言

本文主要实现基于python做一个视觉定位识别的功能，halcon版本使用的是halcon12.0，调用halcon的dll来实现二次开发，下边从头开始设置。
编程环境：python3.8
pyqt5.15
halcon12.0
IDE: VisualStudio Code

基于python+pyqt+halcon实现多算法的模板匹配

一、项目文件目录讲解

1、Resources：文件夹存放的是图片路径，一些资源文件都放在这里
2、Calibration.py、Calibration.ui：这里是视觉功能里边的qt标定界面的ui文件以及转换为py的文件。
3、CameraSetting.py、CameraSetting.ui：这里是视觉功能里边的qt相机设置界面的ui文件以及转换为py的文件。
4、CtuImageMatching.py、CtuImageMatching.ui:这里是视觉功能里边的qt视觉软件的界面的ui文件以及转换为py的文件。
5、CtuImageMatching.qrc：Qt设计的资源文件
6、CtuImageMatchingqrc.py：Qt资源文件的转化为的py文件
7、Helper.py、Helper.ui：这里是视觉功能里边的qt帮助界面的ui文件以及转换为py的文件。
8、RobotVision.py：软件主事件功能，main函数的入口位置，整个视觉软件入口位置

备注：鉴于程序写的比较仓促，因此窗体事件与窗体写在一个文件里边，与窗体事件无关的写在了RobotVision.py中，这种思路不可取，因此如果要重新设计这个目录的时候，都需要用写事件的类继承窗体类，这样改窗体就不用和修改那么多。

二、Qt Designer设置ui界面

一下界面只需要用Qt Designer进行编辑即可，基本上不需要代码部分

0.qrc资源文件的设置

这里需要把Resources文件夹里边的资源文件添加进来。

1.CtuImageMatching.ui的设置

先上图，只需要按照这个来设置即可：

从主界面上可以看出，本视觉软件所具有的功能。

2.CameraSetting.ui的设置

先上图，只需要按照这个来设置即可：

从界面上可以看出，本相机设置具有的功能。

3.Calibration.ui的设置

先上图，只需要按照这个来设置即可：

从界面上可以看出，本标定设置具有的功能。

4.Helper.ui的设置

先上图，只需要按照这个来设置即可：

从界面上可以看出，本帮助界面具有的功能，这里暂时就一个QLabel用来放了个二维码。

三、使用命令把qt文件转成py文件

在CMD命令行中输入一下命令，这里直接上命令代码：

pyrcc5 -o CtuImageMatchingqrc.py CtuImageMatching.qrc
pyuic5 -o CtuImageMatching.py CtuImageMatching.ui
pyuic5 -o CameraSetting.py CameraSetting.ui
pyuic5 -o Calibration.py Calibration.ui
pyuic5 -o Helper.py Helper.ui

四、py文件解析

1.CtuImageMatching.py重要函数解析

首先在主界面，我这里先弄了一个管理整个流程的一个变量的类，变量的意义如代码块的解释

class CurrentControl:def __init__(self):self.setPartPosition = 0.0    # 图片在位置的左上角的位置，为了解决图像居中界面self.ROIRunType = 0   # 目前软件选中的ROI的计算类型：并集、交集、差集、self.ModelNum = 0    # 当前软件使用的模板号(定位的模板号)self.FindModelFun = 0    # 当前软件选择的模板的算法self.CurrentBarCodeType = 6   # 当前软件识别哪种二维码self.CurrentDataCodeType = 0  # 当前软件识别哪种一维码self.hv_WindowHandle = None   # 当前现实图片的窗体self.ho_Image = None   #当前的图像变量self.ROITemp = None    # 绘制ROI的经过运算的变量self.ho_Width = None   # 图像的宽度self.ho_Height = None   # 图像的高度

定义模板的类型，这里是以一个模板单位做一个属性变量：

class ModelCom:def __init__(self):self.EffectiveFlag = False          # 该模板是否有效self.modelNum = -1                  # 模板号self.TemplateAlgorithm = -1         # 匹配算法self.h_img = None                   # 创建模板原图self.h_roi = None                   # 创建模板ROIself.hv_ModelID = None              # 模板匹配IDself.ShapeModelRegions = None       # 模板轮廓self.hv_Orgin_Row = HTuple(-1)      # 模板锚点的行self.hv_Orgin_Column = HTuple(-1)   # 模板锚点的列self.hv_Target_Row = HTuple(-1)     # 锚点的行self.hv_Target_Column = HTuple(-1)  # 锚点的列self.TargetFlag = False             # 设置锚点的标志self.h_SearchROI = None             # 搜索区域self.SearchROIFlag = False          # 拥有搜索区域的标志self.startAngle = -90                 #模板起始角度self.endAngle = 180                   #角度范围self.Level = -1                       #对比度self.Score = 50                       #模板分数self.DeformationNum = 0               #允许变形self.MatchNum = 1                     #匹配个数self.FindModelTimeOut = 1000          #匹配超时事件

定义识别一维码、二维码、ocr的变量属性

class CodeModel:def __init__(self):self.BarCodeROI = None         # 条形码搜索区域self.BarCodeROIFlag = False    # 是否已经设置条形码搜索区域self.QRCodeROI = None          # 二维码搜索区域self.QRCodeROIFlag = False     # 是否已经设置了二维码搜索区域self.OCRCodeROI = None         # OCR的搜索区域self.OCRCodeROIFlag = False    # 是否设置了OCR搜索区域

2.CameraSetting.py重要函数解析

首先设立相机设置页的事件

def CameraInit(self):self.Btn_SertchCarmer.clicked.connect(self.on_Btn_SertchCarmer)    # 查找相机self.Btn_ConnectCarmer.clicked.connect(self.on_Btn_ConnectCarmer)  # 连接相机self.Check_AutoExporeTimeOut.clicked.connect(self.on_Check_AutoExporeTimeOut)   # 自动曝光self.Slider_ExporeTime.valueChanged.connect(self.Slider_ExporeTime_valueChange) # 曝光滑块的事件self.Slider_Gray.valueChanged.connect(self.Slider_Gray_valueChanged)   # 增益滑块事件self.Check_AutoBlanceWhite.clicked.connect(self.Check_AutoBlanceWhite_clicked)  # 是否白平衡self.Btn_ShowImage.clicked.connect(self.on_Btn_ShowImage)   # 预览相机和停止预览按钮self.Btn_GetImage.clicked.connect(self.Btn_GetImage_clicked)  # 快照按钮self.Lab_TenLine.clicked.connect(self.Lab_TenLine_clicked)   # 显示的时候是否显示十字self.Btn_SetROI.clicked.connect(self.Btn_SetROI_clicked)    # 设置ROI，这里类似放大图像self.HalconCameraInitTimer = QTimer(self.layoutWidget)             # 预览图像的定时器self.HalconCameraInitTimer.singleShot(100, self.InitHalconCamera)self.workerTimer1 = QTimer(self.layoutWidget)     # 十字显示的定时器self.workerTimer1.timeout.connect(self.TenLine)#线程self.workerThread = PyThread()self.workerThread.Set_ThreadSleep(0.1)     # 预览图像的线程self.workerThread.threadSignal.connect(self.GetImage)

初始化显示图像的halcon窗体

def InitHalconCamera(self):try:HOperatorSet.CloseWindow(self.hv_WindowHandle)except Exception as e:passHOperatorSet.SetWindowAttr(HTuple("background_color"), HTuple("black"))winID = self.Lab_HShowWindow.winId()self.hv_WindowHandle = HOperatorSet.OpenWindow(HTuple(0), HTuple(0), HTuple(self.Lab_HShowWindow.geometry().width()), HTuple(self.Lab_HShowWindow.geometry().height()), HTuple(winID), HTuple(""), HTuple(""), self.hv_WindowHandle)HOperatorSet.SetColor(self.hv_WindowHandle, HTuple("red"))HOperatorSet.SetDraw(self.hv_WindowHandle, HTuple("margin"))HOperatorSet.SetLineWidth(self.hv_WindowHandle, HTuple(1))

查找相机函数

def on_Btn_SertchCarmer(self):conf = configparser.ConfigParser()conf.read(self.filePath + "\\DefaultSetting.ini")cameraType = conf.get("CameraType","CameraInterface")conf.clear()deviceNames = "DirectShow"if cameraType == "0":deviceNames = "DirectShow"elif cameraType == "1":deviceNames = "GigEVision2"elif cameraType == "2":deviceNames = "GenICamTL"else:passName = Query = Information = ValueList = info_BoardsList = hv_Length = NoneHOperatorSet.InfoFramegrabber(HTuple(deviceNames),HTuple("device"),HTuple(Information),HTuple(ValueList))hv_Length = HOperatorSet.TupleLength(ValueList,HTuple(hv_Length))length1 = hv_Length[0].Iself.Com_CameraList.clear()for i in range(0,length1):strDevice = ValueList[i].Sif deviceNames != "DirectShow":strDevice = re.findall(r'device:(.*?) ',strDevice)[0]if strDevice == "":strDevice = ValueList[i].Sif strDevice == "default":breakfill_name = deviceNames.replace("\"","") + ":" + strDeviceself.Com_CameraList.addItem(fill_name)print(fill_name)

连接相机函数

def OpenCamera(self):Information = ValueList = Nonestr = self.Com_CameraList.currentText()ColorZone = ""try:Driver = str.split(":")if self.Com_ColorZone.count() <=0:if Driver[0] == "DirectShow":ColorZone = "gray"else:ColorZone = "default"else:ColorZone = self.Com_ColorZone.currentText()HOperatorSet.InfoFramegrabber(HTuple(Driver[0]), HTuple("defaults"), HTuple(Information), HTuple(ValueList))self.hv_AcqHandle = HOperatorSet.OpenFramegrabber(HTuple(Driver[0]), HTuple(ValueList[0].I), HTuple(ValueList[1].I), HTuple(ValueList[2].I), HTuple(ValueList[3].I), HTuple(ValueList[4].I), HTuple(ValueList[5].I), HTuple(ValueList[6].S), HTuple(ValueList[7].I), HTuple(ColorZone), HTuple(-1), HTuple(ValueList[10].S), HTuple(ValueList[11].S), HTuple(Driver[1]), HTuple(0), HTuple(ValueList[13].I), self.hv_AcqHandle)print(self.hv_AcqHandle)HOperatorSet.GrabImageStart(self.hv_AcqHandle, HTuple(-1))self.ho_Image = HOperatorSet.GrabImageAsync(self.ho_Image, self.hv_AcqHandle, HTuple(-1))HOperatorSet.GetImageSize(self.ho_Image, self.ho_Width, self.ho_Height)HOperatorSet.SetPart(self.hv_WindowHandle, HTuple(0), HTuple(0), HTuple(self.ho_Height[0].I - 1), HTuple(self.ho_Width[0].I - 1))self.GetCameraInfo(Driver[0])self.OpenCarmerFlag = Trueself.EnableCamera(self.OpenCarmerFlag)return Trueexcept Exception as e:self.CloseCamera()return False

获取已经连接相机的属性

def GetCameraInfo(self,driverName):# 像素格式try:hv_Value = hv_Length = Nonehv_Value = HOperatorSet.GetFramegrabberParam(self.hv_AcqHandle,HTuple("PixelFormat"),hv_Value)print(hv_Value)hv_Length = HOperatorSet.TupleLength(hv_Value, HTuple(hv_Length))length = hv_Length[0].Ifor i in range(0,length):self.Com_PixFormat.addItem(hv_Value[i].S)except Exception as e:pass#颜色空间try:if self.Com_ColorZone.count()<=0:Information = ValueList = hv_Length = NoneHOperatorSet.InfoFramegrabber(HTuple(driverName),HTuple("color_space"),Information,ValueList)hv_Length = HOperatorSet.TupleLength(ValueList, HTuple(hv_Length))length = hv_Length[0].Ifor i in range(0,length):self.Com_ColorZone.addItem(ValueList[i].S)except Exception as e:pass#曝光时间try:hv_Value = Noneif driverName == 'DirectShow':self.Slider_ExporeTime.setMinimum(-13)self.Slider_ExporeTime.setMaximum(-1)self.Slider_ExporeTime.setValue(-1)self.Lab_ExporeTimeOutValue.setText(str(self.Slider_ExporeTime.value()))self.Check_AutoExporeTimeOut.setChecked(True)self.Check_AutoExporeTimeOut.setEnabled(True)self.Slider_ExporeTime.setEnabled(False)HOperatorSet.SetFramegrabberParam(self.hv_AcqHandle, HTuple("exposure"), HTuple("auto"))else:hv_Value = HOperatorSet.GetFramegrabberParam(self.hv_AcqHandle, HTuple("ExposureTime"), hv_Value)extime = hv_Value[0].Dself.Slider_ExporeTime.setMinimum(0)self.Slider_ExporeTime.setMaximum(600000)self.Slider_ExporeTime.setValue(extime)self.Lab_ExporeTimeOutValue.setText(str(self.Slider_ExporeTime.value()))self.Check_AutoExporeTimeOut.setChecked(False)self.Check_AutoExporeTimeOut.setEnabled(False)self.Slider_ExporeTime.setEnabled(True)except Exception as e:pass#增益try:hv_Value = Nonehv_Value = HOperatorSet.GetFramegrabberParam(self.hv_AcqHandle, HTuple("Gain"), hv_Value)gain = hv_Value[0].Dself.Slider_Gray.setMinimum(0)self.Slider_Gray.setMaximum(24)self.Slider_Gray.setValue(gain)self.Lab_GrayValue.setText(str(self.Slider_Gray.value()))self.Slider_Gray.setEnabled(True)except Exception as e:pass

3.Calibration.py重要函数解析

这里主要是使用仿射变换实现坐标转换，比如像素坐标转机器人坐标，首先定义坐标变量的数据，目前只写了3点标定，

class CameraCalibrationPoint:def __init__(self):self.P1_Image_X = -1self.P1_Image_Y = -1self.P1_Robot_X = -1self.P1_Robot_Y = -1self.P2_Image_X = -1self.P2_Image_Y = -1self.P2_Robot_X = -1self.P2_Robot_Y = -1self.P3_Image_X = -1self.P3_Image_Y = -1self.P3_Robot_X = -1self.P3_Robot_Y = -1self.RobotHommatFlag = False     # 是否保存了转换数据self.RobotHommat = None          # 转换矩阵

用到的事件绑定

def BindEvent(self):self.CalibrationNum_ComBo.currentIndexChanged.connect(self.CalibrationNum_ComBo_currentIndexChanged)   # 标定的工位号self.Btn_SaveCalib.clicked.connect(self.Btn_SaveCalib_clicked)    # 保存标定数据self.pushButton_2.clicked.connect(self.pushButton_2_clicked)    # 测试转换数据

标定数据保存

def AffineTran(self,CurrentNum):concat = concat1 = concat2 = concat3 = Nonetry:concat = HOperatorSet.TupleConcat(concat, HTuple(self.MyPoint[CurrentNum].P1_Image_X), concat)concat1 = HOperatorSet.TupleConcat(concat1, HTuple(self.MyPoint[CurrentNum].P1_Image_Y), concat1)concat2 = HOperatorSet.TupleConcat(concat2, HTuple(self.MyPoint[CurrentNum].P1_Robot_X), concat2)concat3 = HOperatorSet.TupleConcat(concat3, HTuple(self.MyPoint[CurrentNum].P1_Robot_Y), concat3)concat = HOperatorSet.TupleConcat(concat, HTuple(self.MyPoint[CurrentNum].P2_Image_X), concat)concat1 = HOperatorSet.TupleConcat(concat1, HTuple(self.MyPoint[CurrentNum].P2_Image_Y), concat1)concat2 = HOperatorSet.TupleConcat(concat2, HTuple(self.MyPoint[CurrentNum].P2_Robot_X), concat2)concat3 = HOperatorSet.TupleConcat(concat3, HTuple(self.MyPoint[CurrentNum].P2_Robot_Y), concat3)concat = HOperatorSet.TupleConcat(concat, HTuple(self.MyPoint[CurrentNum].P3_Image_X), concat)concat1 = HOperatorSet.TupleConcat(concat1, HTuple(self.MyPoint[CurrentNum].P3_Image_Y), concat1)concat2 = HOperatorSet.TupleConcat(concat2, HTuple(self.MyPoint[CurrentNum].P3_Robot_X), concat2)concat3 = HOperatorSet.TupleConcat(concat3, HTuple(self.MyPoint[CurrentNum].P3_Robot_Y), concat3)self.MyPoint[CurrentNum].RobotHommat = HOperatorSet.VectorToHomMat2d(concat,concat1,concat2,concat3,self.MyPoint[CurrentNum].RobotHommat)self.MyPoint[CurrentNum].RobotHommatFlag = Trueself.label_5.setText("OK")except Exception as e:self.MyPoint[CurrentNum].RobotHommatFlag = Falseself.label_5.setText("NG")

测试转换坐标

def PixelToRobot(self,id,x,y):if self.MyPoint[id].RobotHommatFlag == True:try:Qx = Qy = NoneHOperatorSet.AffineTransPoint2d(self.MyPoint[id].RobotHommat,HTuple(float(x)),HTuple(float(y)),HTuple(Qx),HTuple(Qy))return Qx[0].D,Qy[0].Dexcept:return -1,-1return -1,-1

4.Helper.py重要函数解析

这个文件比较简单，主要就显示一张图片而已

class Ui_Helper(object):def setupUi(self, Helper):Helper.setObjectName("Helper")Helper.resize(439, 438)icon = QtGui.QIcon()icon.addPixmap(QtGui.QPixmap(":/CtuImageMatching/Resources/37.png"), QtGui.QIcon.Normal, QtGui.QIcon.Off)Helper.setWindowIcon(icon)self.gridLayout = QtWidgets.QGridLayout(Helper)self.gridLayout.setContentsMargins(11, 11, 11, 11)self.gridLayout.setSpacing(6)self.gridLayout.setObjectName("gridLayout")self.label = QtWidgets.QLabel(Helper)self.label.setText("")self.label.setPixmap(QtGui.QPixmap(":/CtuImageMatching/Resources/38.png"))self.label.setScaledContents(True)self.label.setObjectName("label")self.gridLayout.addWidget(self.label, 0, 0, 1, 1)self.retranslateUi(Helper)QtCore.QMetaObject.connectSlotsByName(Helper)def retranslateUi(self, Helper):_translate = QtCore.QCoreApplication.translateHelper.setWindowTitle(_translate("Helper", "联系我们：Tel:189xxxx2753"))

5.RobotVision.py主界面重要函数

此文件绑定的函数比较多，这里主要讲解重要函数

1.初始化函数

此方法主要是对整个软件的初始化部分,包括各个变量的初始化

def __init__(self, parent=None):super(RobotVision, self).__init__(parent)self.ui = Ui_CtuImageMatchingClass()self.ui.setupUi(self)self.BindEvent()self.RootPath = os.getcwd()self.FilePath = self.RootPath + "\\VisionModel"try:os.mkdir(self.FilePath)except:passfileIni = self.FilePath + "\\DefaultSetting.ini"if os.path.exists(fileIni) == False:conf = configparser.ConfigParser()conf.add_section("CameraType")conf.set("CameraType", "CameraInterface", "0")with open(fileIni, 'w') as conffile:conf.write(conffile)self.CameraWindow = CameraMainWindow()self.Camera = Ui_CameraSetting(self.FilePath)self.Camera.setupUi(self.CameraWindow)self.CalibWindow = CalibrationMainWindow()self.Calib = Ui_Calibration(self.FilePath)self.Calib.setupUi(self.CalibWindow)self.MyHelperWindow = HelperMainWindow()self.MyHelp = Ui_Helper()self.MyHelp.setupUi(self.MyHelperWindow)self.VisionFunCode = ""HOperatorSet.SetSystem(HTuple("clip_region"),HTuple("false"))self.ReadCodeROI()self.ReadModel(0,self.ui.MaxModelNum)self.VisionFunFlag = Trueself.DrawFlag = False

2.halcon窗体初始化

这里主要初始化halcon窗体，是主页面的显示位置

def InitHalcon(self):try:HOperatorSet.CloseWindow(self.ui.MyCurrentControl.hv_WindowHandle)except Exception as e:passHOperatorSet.SetWindowAttr(HTuple("background_color"), HTuple("white"))winID = self.ui.ImageLab.winId()self.ui.MyCurrentControl.hv_WindowHandle = HOperatorSet.OpenWindow(HTuple(0), HTuple(0), HTuple(self.ui.ImageLab.geometry().width()), HTuple(self.ui.ImageLab.geometry().height()), HTuple(winID), HTuple(""), HTuple(""), self.ui.MyCurrentControl.hv_WindowHandle)HOperatorSet.SetColor(self.ui.MyCurrentControl.hv_WindowHandle, HTuple("red"))HOperatorSet.SetDraw(self.ui.MyCurrentControl.hv_WindowHandle, HTuple("margin"))HOperatorSet.SetLineWidth(self.ui.MyCurrentControl.hv_WindowHandle, HTuple(1))self.GetImagePixelTimer = QTimer(self)self.GetImagePixelTimer.timeout.connect(self.GetImagePixel)self.GetImagePixelTimer.start(50)# 线程self.workerThreadGetMore = PyThread()self.workerThreadGetMore.Set_ThreadSleep(0.1)self.workerThreadGetMore.threadSignal.connect(self.GetMoreImage)

3.绘制ROI区域，例子分为绘制矩形

绘制矩形ROI

def on_Rectangle1Action(self):if self.HObjectIsNull(self.ui.MyCurrentControl.ho_Image):returnhv_Row1 = Nonehv_Column1 = Nonehv_Row2 = Nonehv_Column2 = NoneROITemp = NoneHOperatorSet.SetColor(self.ui.MyCurrentControl.hv_WindowHandle, HTuple("red"))HOperatorSet.DrawRectangle1(self.ui.MyCurrentControl.hv_WindowHandle, HTuple(hv_Row1), HTuple(hv_Column1), HTuple(hv_Row2), HTuple(hv_Column2))ROITemp = HOperatorSet.GenRectangle1(ROITemp,hv_Row1,hv_Column1,hv_Row2,hv_Column2)if self.HObjectIsNull(self.ui.MyCurrentControl.ROITemp) == True:self.ui.MyCurrentControl.ROITemp = ROITempelse:self.RunROI(ROITemp)self.ShowRunROI()

4.ROI运算逻辑

这里主要是ROI的运算规则：并集、交集、差集

def RunROI(self,ROIObj):if self.ui.MyCurrentControl.ROIRunType == 0:self.ui.MyCurrentControl.ROITemp = HOperatorSet.Union2(self.ui.MyCurrentControl.ROITemp,ROIObj,self.ui.MyCurrentControl.ROITemp)returnif self.ui.MyCurrentControl.ROIRunType == 1:self.ui.MyCurrentControl.ROITemp = HOperatorSet.Intersection(self.ui.MyCurrentControl.ROITemp, ROIObj, self.ui.MyCurrentControl.ROITemp)returnif self.ui.MyCurrentControl.ROIRunType == 2:self.ui.MyCurrentControl.ROITemp = HOperatorSet.Difference(self.ui.MyCurrentControl.ROITemp, ROIObj, self.ui.MyCurrentControl.ROITemp)return

5.创建模板

这里是创建模板的函数，这里以创建灰度模板为例子

# 创建模板进入的主函数

6.查找模板，实现模板匹配

这里主要实现模板匹配，根据不同的算法实现不同的模板匹配结果

# 模板匹配的总入口
def RunModelAction_triggered(self):if self.ui.MyModelCom[self.ui.MyCurrentControl.ModelNum].EffectiveFlag == False:if QMessageBox.information(self, '提示', '当前模板号无模板', QMessageBox.Yes) == 65536:returnEachRes = []if self.ui.MyModelCom[self.ui.MyCurrentControl.ModelNum].TemplateAlgorithm == 0:EachRes = self.FindModel_Shape(self.ui.MyCurrentControl.ModelNum)elif self.ui.MyModelCom[self.ui.MyCurrentControl.ModelNum].TemplateAlgorithm == 1:EachRes = self.FindModel_Gray(self.ui.MyCurrentControl.ModelNum)elif self.ui.MyModelCom[self.ui.MyCurrentControl.ModelNum].TemplateAlgorithm == 2:EachRes = self.FindModel_NCC(self.ui.MyCurrentControl.ModelNum)elif self.ui.MyModelCom[self.ui.MyCurrentControl.ModelNum].TemplateAlgorithm == 3:EachRes = self.FindModel_ChangeShape(self.ui.MyCurrentControl.ModelNum)else:passif len(EachRes) == 0:self.ui.statusBar.showMessage("模板匹配失败！")else:self.ui.statusBar.showMessage(EachRes[0])
