用Python vc2 在大图中查找小图

import cv2

import time

def find_image_location(small_image_path, large_image_path):

    # Load images

    small_image = cv2.imread(small_image_path)

    large_image = cv2.imread(large_image_path)

    # Find match using template matching

    result = cv2.matchTemplate(large_image, small_image, cv2.TM_CCOEFF_NORMED)

    min_val, max_val, min_loc, max_loc = cv2.minMaxLoc(result)

    # Return location of top-left corner of small image within large image

    return max_loc

#your large picture path

large ='temp\\hua.png' 

#your small picture path

small='temp\\hua4.png'

start_time=time.time()

loc=find_image_location(small,large )

end_time = time.time()

print(loc)

print("耗时: {:.2f}秒".format(end_time - start_time))
