def grayImg():
 for x in range(1,38):
  #读取图片
  img = cv2.imread(\"C:\\\\Users\\\\lyl\\\\Desktop\\\\new_dahuoji\\\\img2\\\\{}.jpg\".format(str(x)))
  GrayImage=cv2.cvtColor(img,cv2.COLOR_BGR2GRAY)
  #保存灰度后的新图片
  cv2.imwrite(\"C:\\\\Users\\\\lyl\\\\Desktop\\\\1\\\\myProject\\\\pictures\\\\dataset2\\\\dahuomiao\\\\{}.jpg\".format(str(x)),GrayImage)
grayImg()
