如何使用 OpenCV 而不是 C++ 将视频分成帧

[英]How to break a video into frames using OpenCV over C++

原文 2011-06-07 07:59:34 4 2 c++/ video/ opencv

I am really new to openCV and I would like to break a video file that I have (*.avi) into separate frames.我对 openCV 真的很陌生，我想将我拥有的视频文件 (*.avi) 分成单独的帧。

Does anyone know how to do it?有谁知道该怎么做？

Thanks!!谢谢！！

Take a look at cvCaptureFromFile , cvQueryFrame and cvSaveImage .看看cvCaptureFromFile 、 cvQueryFrame和cvSaveImage 。 They'll do everything you need.他们会做你需要的一切。

If you're more comfortable with using the C++ API, the VideoCapture class (see http://opencv.jp/opencv-2.2_org/cpp/highgui_reading_and_writing_images_and_video.html#videocapture ) is very convenient to use.
