由于文件路径中的特殊字符，OpenCv imwrite无法正常工作 [英] OpenCv imwrite doesn't work because of special character in file path

问题描述

当文件路径具有特殊字符(例如é")时，我无法保存图像.

I can't save an image when the file path has special character (like "é" for example).

这是来自Python 3 shell的测试:

Here is a test from Python 3 shell :

>>> cv2.imwrite('gel/test.jpg', frame)
True
>>> cv2.imwrite('gel/ééé/test.jpg', frame)
False
>>> cv2.imwrite('gel/eee/test.jpg', frame)
True

有什么想法怎么做?

谢谢！

不幸的是，@ PM2Ring和@DamianLattenero提出的所有建议似乎都无效:(

Unfortunately, all suggestions proposed by @PM2Ring and @DamianLattenero don't seem to work :(

所以，我使用@cdarke的解决方案，这是我的最终代码:

So, I use the @cdarke's solution, here's my final code :

destination = 'gel/ééé/'
gel = 'test.jpg'
script_path = os.getcwd()
os.chdir(destination)
cv2.imwrite(gel, frame)
os.chdir(script_path)

推荐答案

您可以先使用OpenCV对图像进行编码，然后使用numpy tofile()方法保存，因为编码后的图像是一维numpy ndarray:

You can first encode the image with OpenCV and then save it with numpy tofile() method since the encoded image is a one-dim numpy ndarray：

is_success, im_buf_arr = cv2.imencode(".jpg", frame)

im_buf_arr.tofile('gel/ééé/test.jpg')
