python 判断 图片是否相同

二、

import cv2

import numpy as np

image1 = cv2.imread("1.png")

image2 = cv2.imread("22.png")
difference = cv2.subtract(image1, image2)
result = not np.any(difference) #if difference is all zeros it will return False

if result is True:
     print("两张图片一样")
else:
     cv2.imwrite("result.jpg", difference)
     print ("两张图片不一样")
 

结果改一下：

  diff = cv2.subtract(preFrame, frame2)
        if np.max(diff)<10:
            print('diff<10', self.cam_no,np.max(diff))
            return True
        if not np.any(diff):  # 判断为图片相同
            return True
