遍历图像目录并将它们全部旋转 x 度并保存到目录

os.listdir(path) gives you a list of contents of the folder (basically just the name) and then you need to open these files using the ndimage.imread() function.

这应该可行:

from scipy import ndimage, misc
import numpy as np
import os
import cv2

def main():
    outPath = "C:Minicondaenvs.."
    path = "C:Minicondaenvsout.."

    # iterate through the names of contents of the folder
    for image_path in os.listdir(path):

        # create the full input path and read the file
        input_path = os.path.join(path, image_path)
        image_to_rotate = ndimage.imread(input_path)

        # rotate the image
        rotated = ndimage.rotate(image_to_rotate, 45)

        # create full output path, 'example.jpg' 
        # becomes 'rotate_example.jpg', save the file to disk
        fullpath = os.path.join(outPath, 'rotated_'+image_path)
        misc.imsave(fullpath, rotated)

if __name__ == '__main__':
    main()

PS:这种遍历文件夹内容的方式只有在目录中只有文件而没有子目录的情况下才有效.os.listdir(path) 将返回任何文件以及子目录的名称.

PS: This way of iterating through the contents of the folder only works if there are only files in the directory and no sub-directories. os.listdir(path) will return the names of any files as well as sub-directories.

您可以从这篇文章中了解如何仅列出目录中的文件:如何列出一个目录下的所有文件?
