I'm learning OpenCV and Python. I captured some images from my webcam and saved them. But they are being saved by default into the local folder. I want to save them to another folder from direct path. How do I fix it?

推荐答案

ebeneditos提供的解决方案效果很好.

The solution provided by ebeneditos works perfectly.

但是，如果您在大型代码段的多个部分中都有cv2.imwrite()，并且想要更改保存图像的路径，则每次出现cv2.imwrite()时，都必须分别更改路径.

But if you have cv2.imwrite() in several sections of a large code snippet and you want to change the path where the images get saved, you will have to change the path at every occurrence of cv2.imwrite() individually.

正如Soltius所说，这是一种更好的方法.声明路径并将其作为字符串传递给cv2.imwrite()

As Soltius stated, here is a better way. Declare a path and pass it as a string into cv2.imwrite()

import cv2
import os
img = cv2.imread('1.jpg', 1)
path = 'D:/OpenCV/Scripts/Images'
cv2.imwrite(os.path.join(path , 'waka.jpg'), img)
cv2.waitKey(0)

现在，如果要修改路径，只需更改path变量.

Now if you want to modify the path, you just have to change the path variable.
