python 查看文件夹下图片大小 python读取文件夹的所有图片

项目下的image文件夹里有五张.bmp图像

1 import os
 2 import cv2
 3 
 4 def get_img_list(dir, firelist, ext=None):
 5     newdir = dir
 6     if os.path.isfile(dir):  # 如果是文件
 7         if ext is None:
 8             firelist.append(dir)
 9         elif ext in dir[-3:]:
10             firelist.append(dir)
11     elif os.path.isdir(dir):  # 如果是目录
12         for s in os.listdir(dir):
13             newdir = os.path.join(dir, s)
14             get_img_list(newdir, firelist, ext)
15 
16     return firelist
17 
18 def read_img():
19     image_path = './image'
20     imglist = get_img_list(image_path, [], 'bmp')
21     imgall = []
22     for imgpath in imglist:
23         # print(imgpath)
24         imaname = os.path.split(imgpath)[1]  # 分离文件路径和文件名后获取文件名（包括了后缀名）
25         # print(imaname)
26         img = cv2.imread(imgpath, cv2.IMREAD_COLOR)
27         imgall.append(img)
28         cv2.namedWindow(imaname, cv2.WINDOW_AUTOSIZE)
29         cv2.imshow(imaname, img)
30         print(imaname, img.shape)
31     cv2.waitKey(0)
32 
33     return imgall
34 
35 if __name__ == '__main__':
36     imgall = read_img()
37     print(imgall.__len__())

 

最后图片显示
