我正在使用 python 在 opencv 中尝试立体校准。我正在使用 python 版本 2.7.1 和 openCV 版本 2.4.2 当我运行代码时，我收到一条错误消息，指出要解压缩的值太多。下面是我的代码：
objpts=[]
objPoints = []
pointCounts = hor*ver
R = [8]
T = [8]
E=[]
F=[]
R1 = []
R2 = []
P1=[]
P2 =[]
objectPoints = []
imgPoints1 = []
imgPoints2 = []
imagePoints2 = []
imagePoints1 = []
while ((len(imagePoints1) < hor*ver) and (len(imagePoints2)< hor*ver)):
ret,imgr = webCamHndlr_r.read(0)
ret,imgl = webCamHndlr_l.read(1)
grey_imgr = cv2.cvtColor(imgr, cv.CV_BGR2GRAY)
grey_imgl = cv2.cvtColor(imgl, cv.CV_BGR2GRAY)
ret, cornersr =cv2.findChessboardCorners(grey_imgr,dims)
cv2.drawChessboardCorners(grey_imgr,dims,cornersr,0)
ret, cornersl =cv2.findChessboardCorners(grey_imgl,dims)
cv2.drawChessboardCorners(grey_imgl,dims,cornersl,0)
cv2.imshow("chessboard", grey_imgr)
cv2.imshow("chessboard1", grey_imgl)
objPoints = np.zeros((hor*ver,3), np.float32)
objPoints[:,:2] = np.mgrid[0:hor,0:ver].T.reshape(-1,2)
if cv.WaitKey(-1) == 32:
imagePoints1.append(cornersl)
imagePoints2.append(cornersr)
print len(imagePoints1)
objectPoints.append(objPoints)
cv2.imwrite("./test_images/img_r"+str(i)+".jpg",imgr)
cv2.imwrite("./test_images/img_l"+str(i)+".jpg",imgl)
i = i+1;
if cv2.waitKey(10) == 27:
break
objectPoints = [np.asarray(x) for x in objectPoints]
imagePoints1 = [np.asarray(x) for x in imagePoints1]
imagePoints2 = [np.asarray(x) for x in imagePoints2]
if( len(imagePoints1[0])== len(imagePoints2[0]) == len(objectPoints[0]) == len(objectPoints)== len(imagePoints2) == len(imagePoints1) ) : print len(imagePoints1[0])
cameraMatrix1, distCoeffs1, cameraMatrix2, distCoeffs2, R, T, E, F = cv2.stereoCalibrate(objectPoints, imagePoints1, imagePoints2, (320,240))
print R
cv.StereoRectify(cameraMatrix1, cameraMatrix2, distCoeffs1, distCoeffs2,(imgr.width,imgr.height), R, T, R1, R2, P1, P2, Q, CV_CALIB_ZERO_DISPARITY, -1, (0, 0))
print Q
np.savetxt('Q_mat.txt',Q)
我得到的错误是：
回溯（最后一次调用）：文件“depth_estimation.py”，第 82 行，在 cameraMatrix1、distCoeffs1、cameraMatrix2、distCoeffs2、R、T、E、F = cv2.stereoCalibrate(objectPoints、imagePoints1、imagePoints2、(320,240)) ValueError : 太多值无法解压
我给出了一个对象点数组，每个对象点又是一个点数组。
