python切割图片的实现示例_python_

import os from cv2 import cv2 def split_image(src_path, rownum, colnum, file): img = cv2.imread(src_path) # cv2.imwrite(path, img) size = img.shape[0:2] w = size[1] h = size[0] # print(file, w, h) # 每行的高度和每列的宽度 row_height = h // rownum col_width = w // rownum num = 0 for i in range(rownum): for j in range(colnum): # 保存切割好的图片的路径，记得要填上后缀，以及名字要处理一下，可以是 # src_path.split('.')[0] + '_' + str((i+1)*(j+1)) + '.jpg' save_path = '' row_start = j * col_width row_end = (j+1) * col_width col_start = i * row_height col_end = (i+1) * row_height # print(row_start, row_end, col_start, col_end) # cv2图片： [高， 宽] child_img = img[col_start:col_end, row_start:row_end] cv2.imwrite(save_path, child_img) if __name__ == '__main__': # 可以遍历文件夹 # file_path = r'我是路径（文件夹路径）' # for file in file_names: # src_path 具体图片路径，包含后缀 src_path = '' row = 4 col = 4 split_image(src_path, row, col, file.split('.')[0])
