这篇文章主要介绍了python如何实现连连看图像识别辅助程序，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。
总体思路
1、获取连连看程序的窗口并前置
2、游戏界面截图，将每个一小图标切图，并形成由小图标组成的二维列表
3、对图片的二维列表遍历，将二维列表转换成由数字组成的二维数组，图片相同的数值相同。
4、遍历二维数组，找到可消除的对象，实现算法：
两个图标相邻。（一条线连接）
两个图标同行，同列，且中间的图标全部为空（数值为0）（一条线连接）
两条线连接，转弯一次，路径上所有图标为空。（二条线连接）
三条线连接，转弯二次，路径上所有图标为空。（三条线连接）
分别点击两个图标，并将对应的二维数据值置为0
实现过程中遇到的问题
图片切割
im = image.crop((left,top,right,bottom)) //image.crop参数为一个列表或元组，顺序为(left,top,right,bottom)
找到游戏运行窗口
hdwd = win32gui.FindWindow(0,wdname) # 设置为最前显示 win32gui.SetForegroundWindow(hdwd)
窗口不要点击最小化，点击后无法弹出来。
图片缩放并转为灰度
img1 = im1.resize((20, 20), Image.ANTIALIAS).convert('L')
Image.ANTIALIAS 为抗锯齿的选项，图片无毛边。
获取图片每个点的RGB值
pi1 = list(img1.getdata())
列表每个元素为一个三位数的值，分别代表该点的RGB值。列表pi1共400个元素。（因为图片为20*20）
鼠标点击消除
PyMouse.click()该方法默认双击，改为PyMouse.press() 或 PyMouse.release()
判断图片相似
汉明距离，平均哈希
def compare_img(self,im1,im2):
img1 = im1.resize((20, 20), Image.ANTIALIAS).convert('L')
img2 = im2.resize((20, 20), Image.ANTIALIAS).convert('L')
pi1 = list(img1.getdata())
pi2 = list(img2.getdata())
avg1 = sum(pi1) / len(pi1)
avg2 = sum(pi2) / len(pi2)
hash2 = "".join(map(lambda p: "1" if p > avg1 else "0", pi1))
hash3 = "".join(map(lambda p: "1" if p > avg2 else "0", pi2))
match = 0
for i in range(len(hash2)):
if hash2[i] != hash3[i]:
match += 1
# match = sum(map(operator.ne, hash2, hash3))
# match 值越小，相似度越高
return match计算直方图
from PIL import Image
# 将图片转化为RGB
def make_regalur_image(img, size=(8, 8)):
gray_image = img.resize(size).convert('RGB')
return gray_image
# 计算直方图
def hist_similar(lh, rh):
assert len(lh) == len(rh)
hist = sum(1 - (0 if l == r else float(abs(l - r)) / max(l, r)) for l, r in zip(lh, rh)) / len(lh)
return hist
# 计算相似度

calc_sim = hist_similar(li.histogram(), ri.histogram())
return calc_sim

# 利用image对图像大小重新设置, Image.ANTIALIAS为高质量的

# 求图片的范数？？

# dot返回的是点积，对二维数组（矩阵）进行计算
