如何稳定网络摄像头视频? [英] How to stabilize Webcam video?

问题描述

我是OpenCV的新手.我想使用光流方法来稳定网络摄像头实时视频.实际上，我可以稳定视频文件，但是当我尝试应用网络摄像头时却无法正常工作.

I`m new in OpenCV. I want to use optical flow method to stabilize Webcam Real-time video. Actually, I can stabilize video file but when I tried to apply Webcam it does not work.

请帮助我！

推荐答案

昨天我刚刚在该主题上做了一些工作(在Python中)，主要步骤是:

Yesterday I just did some works (in Python) on this subject, main steps are:

1. 使用cv2.goodFeaturesToTrack查找好的角落.
2. 使用cv2.calcOpticalFlowPyrLK跟踪角点.
3. 使用cv2.findHomography计算单应性矩阵.
4. 使用cv2.warpPerspective转换视频帧.

1. use cv2.goodFeaturesToTrack to find good corners.
2. use cv2.calcOpticalFlowPyrLK to track the corners.
3. use cv2.findHomography to compute the homography matrix.
4. use cv2.warpPerspective to transform video frame.

但是结果不是那么理想，可能是我应该选择goodFeatures以外的其他SIFT keypoints.

But the result is not that ideal now, may be I should choose SIFT keypoints other than goodFeatures.
