Write custom size and position batch image cropping through python

foreword

  We often need to crop images in batches. Use the following code to crop in batches as needed. You only need to replace the file path, and three positions are provided for cropping. Mode 1 is the origin, if you choose 2 It is the upper left corner, and if you choose 3, it is the upper right corner. You can also add mode==n...

1. The code is as follows (example):

import cv2
import os

# 定义裁剪的尺寸
width, height = 684, 384

# 读入文件夹路径
src_folder = '/path/to/src/folder'  #原始文件路径
dst_folder = '/path/to/dst/folder'   #保存文件的路径

# 选择裁剪的方式 1就是以原点，如果选择2就是左上角，如果选择3就是右上角
mode = 2  #This 选择

# 设置裁剪的位置
if mode == 1:
    start_point = (0, 0)
elif mode == 2:
    start_point = (0, 0)
elif mode == 3:
    start_point = (0, height - 384)
else:
    raise Exception("无效的裁剪方式")

# 创建目标文件夹
if not os.path.exists(dst_folder):
    os.makedirs(dst_folder)

# 遍历文件夹内的所有图片
for file_name in os.listdir(src_folder):
    file_path = os.path.join(src_folder, file_name)

    # 读入图片
    img = cv2.imread(file_path)

    # 裁剪图片
    cropped_img = img[start_point[1]:start_point[1]+height, start_point[0]:start_point[0]+width]

    # 保存裁剪后的图片
    dst_path = os.path.join(dst_folder, file_name)
    cv2.imwrite(dst_path, cropped_img)
