测试图片可以从这里找

以下两行代码似乎因为版本更替原因都无效了

deparsity = cv2.StereoBM(cv2.STEREO_BM_BASIC_PRESET,ndisparities=16, SADWindowSize=15)

deparsity = cv2.createStereoBM(numDisparities=16, blockSize=25)

#测试代码如下：

# -*- coding: UTF-8 -*-
import numpy as np
import cv2
from matplotlib import pyplot as plt   #import the library

left_img = cv2.imread(‘Tsukuba_L.png‘,0)  #read the left_image(grey)
left_img_rgb = cv2.imread(‘Tsukuba_L.png‘,cv2.IMREAD_COLOR) #read the left_image(colorful)

right_img = cv2.imread(‘Tsukuba_R.png‘,0)      #read the right_image(grey)
right_img_rgb = cv2.imread(‘Tsukuba_R.png‘,cv2.IMREAD_COLOR)  #read the right_image(colorful)

matching=cv2.StereoBM_create(numDisparities=16, blockSize=15) #set the parameters of the stereo

disparity = matching.compute(left_img,right_img) #make the depth map
cv2.imshow("left_img",left_img_rgb)    #show the left_image(colorful)
cv2.imshow("right_img",right_img_rgb)  #show the right_image(colorful)
plt.imshow(disparity,‘gray‘)           #show the depth map(grey)
plt.show()
