這篇文章主要介紹了python如何實現連連看圖像識別輔助程序,具有一定借鑒價值,感興趣的朋友可以參考下,希望大家閱讀完這篇文章之后大有收獲,下面讓小編帶著大家一起了解一下。
總體思路
1、獲取連連看程序的窗口并前置
2、游戲界面截圖,將每個一小圖標切圖,并形成由小圖標組成的二維列表
3、對圖片的二維列表遍歷,將二維列表轉換成由數字組成的二維數組,圖片相同的數值相同。
4、遍歷二維數組,找到可消除的對象,實現算法:
兩個圖標相鄰。(一條線連接)
兩個圖標同行,同列,且中間的圖標全部為空(數值為0)(一條線連接)
兩條線連接,轉彎一次,路徑上所有圖標為空。(二條線連接)
三條線連接,轉彎二次,路徑上所有圖標為空。(三條線連接)
分別點擊兩個圖標,并將對應的二維數據值置為0
實現過程中遇到的問題
圖片切割
im = image.crop((left,top,right,bottom)) //image.crop參數為一個列表或元組,順序為(left,top,right,bottom)
找到游戲運行窗口
hdwd = win32gui.FindWindow(0,wdname) # 設置為最前顯示 win32gui.SetForegroundWindow(hdwd)
窗口不要點擊最小化,點擊后無法彈出來。
圖片縮放并轉為灰度
img1 = im1.resize((20, 20), Image.ANTIALIAS).convert('L')
Image.ANTIALIAS 為抗鋸齒的選項,圖片無毛邊。
獲取圖片每個點的RGB值
pi1 = list(img1.getdata())
列表每個元素為一個三位數的值,分別代表該點的RGB值。列表pi1共400個元素。(因為圖片為20*20)
鼠標點擊消除
PyMouse.click()該方法默認雙擊,改為PyMouse.press() 或 PyMouse.release()
判斷圖片相似
漢明距離,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
計算直方圖
from PIL import Image # 將圖片轉化為RGB def make_regalur_image(img, size=(8, 8)): gray_image = img.resize(size).convert('RGB') return gray_image # 計算直方圖 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 # 計算相似度 def calc_similar(li, ri): calc_sim = hist_similar(li.histogram(), ri.histogram()) return calc_sim if __name__ == '__main__': image1 = Image.open('1-10.jpg') image1 = make_regalur_image(image1) image2 = Image.open('2-11.jpg') image2 = make_regalur_image(image2) print("圖片間的相似度為", calc_similar(image1, image2)) # 值在[0,1]之間,數值越大,相似度越高
圖片余弦相似度
from PIL import Image from numpy import average, dot, linalg # 對圖片進行統一化處理 def get_thum(image, size=(64, 64), greyscale=False): # 利用image對圖像大小重新設置, Image.ANTIALIAS為高質量的 image = image.resize(size, Image.ANTIALIAS) if greyscale: # 將圖片轉換為L模式,其為灰度圖,其每個像素用8個bit表示 image = image.convert('L') return image # 計算圖片的余弦距離 def image_similarity_vectors_via_numpy(image1, image2): image1 = get_thum(image1) image2 = get_thum(image2) images = [image1, image2] vectors = [] norms = [] for image in images: vector = [] for pixel_tuple in image.getdata(): vector.append(average(pixel_tuple)) vectors.append(vector) # linalg=linear(線性)+algebra(代數),norm則表示范數 # 求圖片的范數?? norms.append(linalg.norm(vector, 2)) a, b = vectors a_norm, b_norm = norms # dot返回的是點積,對二維數組(矩陣)進行計算 res = dot(a / a_norm, b / b_norm) return res if __name__ == '__main__': image1 = Image.open('1-9.jpg') image2 = Image.open('8-6.jpg') cosin = image_similarity_vectors_via_numpy(image1, image2) print('圖片余弦相似度', cosin) # 值在[0,1]之間,數值越大,相似度越高,計算量較大,效率較低
