Hi All,

I’ve seen some cool concepts and techniques discussed on this and other forums related to automated action tracking capture platforms like soloshot and some others.

I have been working on a vision based video tracking application prototype which can track subjects or activity with a wide angle or 360 degree cam, in real-time. At a wide angle, we capture at a higher resolution than needed for the finished product and crop/pan in software centering the subject. With 360, we can track a target infinitely around the point of capture. The feed can be processed in real-time so you could potentially throw the output up on a live screen. By in-line processing this way we can eliminate a gimbal or mechanical tracking platform altogether.

Here is a demo of a static camera capturing boxing activity. https://www.youtube.com/watch?v=q2wzOp3x0_k&feature=youtu.be
This is a prototype, so the motion action is not that smooth, but it proves the concept in that it successfully ignored the distractions outside the center of action. It was captured on a 7dmarkii at 1080p/30fps, and the output was 854×480. The prototype could process 4k video as a feed and output 1080p@30fps

There is no product yet, but I’d like to understand who would be the potential users of something like this.

I thought one use would be video capture at events, which is why this topic caught my eye. You could use this as a primary or secondary feed, and cut back and forth. With no operator or additional hardware, there is a lot more flexibility with camera position. You could even pull out multiple, simultaneous feeds from different areas of the input frame.

Please feel free to comment or advise me on some use cases for something like this.

Thanks!
