Python 识别12306图片验证码物品的实现示例

from PIL import Image
#切割图像，由于下载的图片都是有固定的位置，所以直接控制像素进行切割就行了
def cut_img(im, x, y):
  assert 0 <= x <= 3
  assert 0 <= y <= 2
  left = 5 + (67 + 5) * x
  top = 41 + (67 + 5) * y
  right = left + 67
  bottom = top + 67
  return im.crop((left, top, right, bottom))
 
if __name__ == '__main__':
  im = Image.open("./pic1.jpg")
  #控制y轴
  for y in range(2):
    #控制x轴
    for x in range(4):
      im2 = cut_img(im, x, y)
      im2.save('./images/%s_%s.png'%(y,x))
