推荐答案

我猜你的垫子没有正确初始化，但是当我读到它是另一个问题。对于这类问题，您最好在OpenCV论坛中搜索和询问。



以下是使用BackgroundSubtractorMOG2获取图片，这对你有帮助。

I would guess that your Mat back isnt proper initialized, but as I read it is another problem. For that kind of question you better search and ask in the OpenCV forum.

Here is some example code for Using BackgroundSubtractorMOG2 for images which should help you.
