今天小编就为大家分享一篇python实现对任意大小图片均匀切割的示例，具有很好的参考价值，希望对大家有所帮助。一起跟随小编过来看看吧

改代码是在windows 系统下

打开路径和保存路径换成自己的就可以啦~

									import numpy as np

									import matplotlib

									import os

									def img_seg(dir):

									  files = os.listdir(dir)

									  for file in files:

									    a, b = os.path.splitext(file)

									    img = Image.open(os.path.join(dir + "\\" + file))

									    hight, width = img.size

									    w = 256

									    id = 1

									    i = 0

									    while (i + w <= hight):

									      j = 0

									      while (j + w <= width):

									        new_img = img.crop((i, j, i + w, j + w))

									        #rename = "D:\\labelme\\images\\"

									        rename = "D:\\labelme\\annotations\\"

									        new_img.save(rename + a + "_" + str(id) + b)

									        id += 1

									        j += w

									      i = i + w

									if __name__ == '__main__':

									  #path = "D:\\labelme\\data\\images\\train"

									  path = "D:\\labelme\\data\\dataset_png"

									  img_seg(path)
