python大图中识别小图位置

import cv2
import numpy as np


def find_template(template_path, image_path):
    # 加载模板和图像，并将它们转换成灰度图像
    template = cv2.imread(template_path, 0)
    image = cv2.imread(image_path, 0)

    # 使用模板匹配算法找到小图在大图中的位置
    result = cv2.matchTemplate(image, template, cv2.TM_CCOEFF_NORMED)
    min_val, max_val, min_loc, max_loc = cv2.minMaxLoc(result)
    print(min_val)
    print(max_val)
    print(min_loc)
    print(max_loc)
    # 将识别结果可视化
    top_left = max_loc
    bottom_right = (top_left[0] + template.shape[1], top_left[1] + template.shape[0])
    cv2.rectangle(image, top_left, bottom_right, 255, 2)

    # 展示识别结果
    cv2.imshow('Result', image)
    cv2.waitKey(0)
    cv2.destroyAllWindows()


# 调用函数进行图像识别
find_template('D://a/22.png', 'D://a/11.png')
