300WLP、AFLW2000真实标签的读取

300WLP数据有成对的图片(jpg)和标签组成的，标签都以mat形式保存的，里面包含了了【'__header__', '__version__', '__globals__', 'pt2d', 'roi', 'Illum_Para', 'Color_Para', 'Tex_Para', 'Shape_Para', 'Exp_Para', 'Pose_Para'】，AFLW2000类似

import h5py
from scipy.io import loadmat
import numpy as np
import mathif __name__ == "__main__":mat_path = "./300W_LP/AFW/AFW_134212_1_0.mat"c_mat = loadmat(mat_path)print(c_mat.keys())#人脸68个关键点landmarks = np.array(np.transpose(c_mat['pt2d'])).astype('float').reshape(-1, 2)print("landmarks \n", landmarks)#头部姿态角的俯仰、偏航和滚转角（以弧度的形式表示），并将弧度制转变为以度（°）为单位Pose_Para = c_mat['Pose_Para']pitch = Pose_Para[0][0] * 180 / math.piyaw = Pose_Para[0][1] * 180 / math.piroll = Pose_Para[0][2] * 180 / math.piprint("pitch: {} yaw: {} roll: {}".format(pitch, yaw, roll))

头部姿态输出：

pitch: -18.200389713407343 yaw: 26.86726114746613 roll: -8.615160925626265

300wlp数据集有68个关键点坐标

from scipy.io import loadmat
import cv2if __name__ == '__main__':c_mat = loadmat("/300W_LP/landmarks/AFW/AFW_134212_1_0_pts.mat")print(c_mat.keys())print(c_mat['pts_2d'])print(c_mat['pts_2d'].shape)img = cv2.imread("/300W_LP/AFW/AFW_134212_1_0.jpg")for x, y in c_mat['pts_2d']:x = int(x)y = int(y)cv2.circle(img, (x, y), 2, (0, 0, 255), 2)cv2.imshow('0', img)# cv2.imwrite("test.jpg", img)cv2.waitKey(0)

头部姿态估计的标签都保存在了txt文件中，

import numpy as npdef get_pose_angle(pose_path):pose_annot = open(pose_path, 'r')R = []for line in pose_annot:line = line.strip('\n').split(' ')L = []if line[0] != '':for nb in line:if nb == '':continueL.append(float(nb))R.append(L)R = np.array(R)T = R[3,:]R = R[:3,:]pose_annot.close()R = np.transpose(R) # 求矩阵的转置roll = -np.arctan2(R[1][0], R[0][0]) * 180 / np.piyaw = -np.arctan2(-R[2][0], np.sqrt(R[2][1] ** 2 + R[2][2] ** 2)) * 180 / np.pipitch = np.arctan2(R[2][1], R[2][2]) * 180 / np.pireturn pitch, yaw, rollif __name__ == '__main__':post_path = "./Biwi Kinect Head Pose Database/hpdb/01/frame_00036_pose.txt"pitch, yaw, roll = get_pose_angle(post_path)print("pitch:{} yaw:{} roll:{}".format(pitch, yaw, roll))

发现不少有问题的图片，如AFLW2000中image03714.jpg（pitch: -29.543809085066318 yaw: -11.260400983618409 roll: -29.381892620601995）;image03282.jpg （pitch: 30.66166858048187 yaw: -77.87501653892568 roll: -31.465400845779367）;
