基于从text文件，选择文件夹中的图片

import cv2

import os

path = r'C:\Users\Lenovo\Desktop\mbdata\VOCdevkit\VOC2012\JPEGImages'

save_picture_path = r'C:\Users\Lenovo\Desktop\mbdata\VOCdevkit\VOC2012\Testpicture'

f = open('test.txt', encoding='gbk')

txt = []

for line in f:

txt.append(line.strip())

for picture_name in txt:

picture_name = picture_name + ".jpg"

picture_path = os.path.join(path, picture_name)

image = cv2.imread(picture_path)

save_picture_path_name = os.path.join(save_picture_path, picture_name)

cv2.imwrite(save_picture_path_name, image)
