Python 2.7: cv2.stereoCalibrate() 错误。未找到所需参数 'distCoeffs1'（位置 5）

Question

我正在使用 Python 2.7 和 OpenCV 3.3 进行立体相机校准。我使用的代码是（我从Stereo Calibration Opencv Python and Disparity Map得到的）：

import numpy as np
import cv2
import glob

# termination criteria
criteria = (cv2.TERM_CRITERIA_EPS + cv2.TERM_CRITERIA_MAX_ITER, 30, 0.001)
# prepare object points, like (0,0,0), (1,0,0), (2,0,0) ....,(6,5,0)
objp = np.zeros((6*7,3), np.float32)
objp[:,:2] = np.mgrid[0:7,0:6].T.reshape(-1,2)

# Arrays to store object points and image points from all the images.
objpointsL = [] # 3d point in real world space
imgpointsL = [] # 2d points in image plane.
objpointsR = []
imgpointsR = []

images = glob.glob('left*.jpg')

for fname in images:
    img = cv2.imread(fname)
    grayL = cv2.cvtColor(img,cv2.COLOR_BGR2GRAY)

    # Find the chess board corners
    ret, cornersL = cv2.findChessboardCorners(grayL, (7,6),None)
    # If found, add object points, image points (after refining them)
    if ret == True:
        objpointsL.append(objp)

        cv2.cornerSubPix(grayL,cornersL,(11,11),(-1,-1),criteria)
        imgpointsL.append(cornersL)

images = glob.glob('right*.jpg')

for fname in images:
    img = cv2.imread(fname)
    grayR = cv2.cvtColor(img,cv2.COLOR_BGR2GRAY)

    # Find the chess board corners
    ret, cornersR = cv2.findChessboardCorners(grayR, (7,6),None)

    # If found, add object points, image points (after refining them)
    if ret == True:
        objpointsR.append(objp)

        cv2.cornerSubPix(grayR,cornersR,(11,11),(-1,-1),criteria)
        imgpointsR.append(cornersR)


retval,cameraMatrix1, distCoeffs1, cameraMatrix2, distCoeffs2, R, T, E, F = cv2.stereoCalibrate(objpointsL, imgpointsL, imgpointsR, (640,480))

但是我得到了这样的错误：

retval,cameraMatrix1, distCoeffs1, cameraMatrix2, distCoeffs2, R, T, E, F = cv2.stereoCalibrate(objpointsL, imgpointsL, imgpointsR, (640,480))
TypeError: Required argument 'distCoeffs1' (pos 5) not found

我的代码、左图和右图在同一个文件夹中。我读过其他类似的答案，但他们没有收到此错误。 (Stereo Calibration Opencv Python and Disparity Map)。我想知道为什么会出现这个错误以及如何解决这个问题？

Answer 1

尝试将代码的最后几行更改为

cameraMatrix1 = None
distCoeffs1 = None
cameraMatrix2 = None
distCoeffs2 = None
R = None
T = None
E = None
F = None
retval, cameraMatrix1, distCoeffs1, cameraMatrix2, distCoeffs2, R, T, E, F = cv2.stereoCalibrate(objpointsL, imgpointsL, imgpointsR, (640,480), flags=cv2.cv.CV_CALIB_FIX_INTRINSIC)

Python 2.7: cv2.stereoCalibrate() 错误。未找到所需参数 'distCoeffs1'（位置 5）

Python 2.7: Error in cv2.stereoCalibrate(). Required argument 'distCoeffs1' (pos 5) not found
