Question

我想在ClashOfClans中找到一些对象（TownHall，Collector等）。我尝试使用OpenCV。我创建用于查找TownHall的模板。 template.bmp 代码：

import cv2 as cv
import numpy
from matplotlib import  pyplot as plt
img = cv.imread('screen_4.jpg',0)
img2 = img.copy()

template = cv.imread('temp_2.bmp',0)
w, h  = template.shape[::-1]


methods = ['cv.TM_CCOEFF', 'cv.TM_CCOEFF_NORMED', 'cv.TM_CCORR',
        'cv.TM_CCORR_NORMED', 'cv.TM_SQDIFF', 'cv.TM_SQDIFF_NORMED']

for meth in methods:
    img = img2.copy()
    method = eval(meth)

    rev = cv.matchTemplate(img, template, method)
    min_val, max_val, min_loc, max_loc = cv.minMaxLoc(rev)

    if method in [cv.TM_SQDIFF, cv.TM_SQDIFF_NORMED]:
        top_left = min_loc
    else:
        top_left = max_loc

    bottom_right = (top_left[0] + w, top_left[1] + h)

    cv.rectangle(img, top_left, bottom_right, 255, 2)

    print(top_left, bottom_right)

    plt.subplot(121), plt.imshow(rev, cmap='gray')
    plt.title('Matching Result'), plt.xticks([]), plt.yticks([])
    plt.subplot(122), plt.imshow(img, cmap='gray')
    plt.title('Detected Point'), plt.xticks([]), plt.yticks([])
    plt.suptitle(meth)
    plt.show()

但是我的结果不稳定。但是对于一张图片却有效，而对于另一张图片则无效。你能提供什么？如何通过模板识别屏幕快照中的对象？

如何在游戏中找到一些物体？
