一、参考：opencv+python判断两张图片是否相同

第一种写法：

一、

import numpy as np 
import cv2 
global n 
zong=0
n = 0 
img1 = cv2.imread('1.png', cv2.IMREAD_GRAYSCALE) 
img2 = cv2.imread('22.png', cv2.IMREAD_GRAYSCALE) 
height, width = img1.shape 
for line in range(height): 
    for pixel in range(width): 
        if img1[line][pixel] != img2[line][pixel]: 
            n = n + 1 

print (n)

第二种写法：

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")
