我在使用cv2.solvePnP
从 OpenCV 调用的函数时遇到问题。该函数用于获取棋盘的姿态估计。在下面的代码之后,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:
ret,rotationVectors,translationVectors,inliers = cv2.solvePnP(objp,corners2,matrix,distortion)ValueError:没有足够的值来解包(预期4,得到3)
