滑动验证码获取像素偏移量

import cv2
# 目标图片
img = cv2.imread(\'目标图片.jpg\', 0)
# 滑块图片
template = cv2.imread(\'滑块图片.png\', 0)
# 获取滑块图片大小
w, h = template.shape[::-1]
# 对比结果
res = cv2.matchTemplate(img, template, cv2.TM_SQDIFF_NORMED)

min_val, max_val, min_loc, max_loc = cv2.minMaxLoc(res)
top_left = min_loc[0]

print(\'偏移像素\',top_left)
