02 图片批量剪切

安装:

pip3 install cv2

# 没有找到cv2应该安装opencv-python
pip3 install opencv-python

使用:

from PIL import Image
import os
import os.path
import numpy as np
import cv2

image_path = r'F:\whole-develop\offline\crawler\scrapy_frame\first_scrapy\first_scrapy\scripts\image'
ok_iamge_path = r'F:\whole-develop\offline\crawler\scrapy_frame\first_scrapy\first_scrapy\scripts\ok_image'

# 指明被遍历的文件夹
rootdir = image_path
for parent, dirnames, filenames in os.walk(rootdir):  # 遍历每一张图片
    for filename in filenames:
        print('parent is :' + parent)
        print('filename is :' + filename)
        currentPath = os.path.join(parent, filename)
        print('the fulll name of the file is :' + currentPath)

        img = Image.open(currentPath)
        print(img.format, img.size, img.mode)
        # img.show()
        # (left, upper, right, lower
        box1 = (0, 19, 189, 272)  # 设置左、上、右、下的像素
        image1 = img.crop(box1)  # 图像裁剪
        image1.save(ok_iamge_path + '\\' + filename)  # 存储裁剪得到的图像
