Python TypeError:Opencv中的自我类型不正确（必须是'；StereoMatcher'；或其衍生物）

说明： 我正在跟踪调查，以找出差距

代码：

import cv2
from matplotlib import pyplot as plt
imgL = cv2.imread('tsukuba_l.png',0)
imgR = cv2.imread('tsukuba_r.png',0)
stereo = cv2.StereoBM(numDisparities=16, blockSize=15)
disparity = stereo.compute(imgL,imgR)
plt.imshow(disparity,'gray')
plt.show()

File "D:drawing-epipolar-lines/untitled0.py", line 15, in <module>
disparity = stereo.compute(imgL,imgR)
TypeError: Incorrect type of self (must be 'StereoMatcher' or its derivative)

但我得到的错误是：

import cv2
from matplotlib import pyplot as plt
imgL = cv2.imread('tsukuba_l.png',0)
imgR = cv2.imread('tsukuba_r.png',0)
stereo = cv2.StereoBM(numDisparities=16, blockSize=15)
disparity = stereo.compute(imgL,imgR)
plt.imshow(disparity,'gray')
plt.show()

File "D:drawing-epipolar-lines/untitled0.py", line 15, in <module>
disparity = stereo.compute(imgL,imgR)
TypeError: Incorrect type of self (must be 'StereoMatcher' or its derivative)

文件“D:绘制极线/untitled0.py”，第15行，in
视差=立体计算（imgL，imgR）
TypeError:自我类型不正确（必须是“StereoMatcher”或其衍生物）

这对您有帮助吗
