我对OpenCV中名为cv2.solvePnP
的函数有问题。此函数用于获得棋盘的姿势估计。在以下代码之后,我得到一个错误:
for fname in glob.glob('Images/Calibragem/img1*.jpg'):
img = cv2.imread(fname)
gray = cv2.cvtColor(img,cv2.COLOR_BGR2GRAY)
ret, corners = cv2.findChessboardCorners(gray, (9,6), None)
if ret==True:
corners2=cv2.cornerSubPix(gray,corners,(11,11),(-1,-1), criteria)
#finds the vectors of rotation and translation
ret, rotationVectors, translationVectors, inliers =
cv2.solvePnP(objp, corners2, matrix, distortion)
#projects the 3D points in the image
imgpts,jac = cv2.projectPoints(axis,rotationVectors,translationVectors,matrix,distortion)
imgAxis=drawAxis(img,corners2,imgpts)
cv2.imshow('imgAxis', imgAxis)
cv2.imwrite('imgAxis.png',imgAxis)
错误说明:
ret, rotationVectors, translationVectors, inliers = cv2.solvePnP(objp, corners2, matrix, distortion) ValueError: not enough values to unpack (expected 4, got 3)
从opencv2 documentation:
因此只有3个值需要解压缩。
^{pr2}$因此,您应该能够修复:
As solvePnP()只返回}。在
