Hello,
I have a video of me sweeping a laser pointer over a static scene and I would like to turn that video into a picture of the scene with the laser curve from beginning to end on it.
If someone could point me in the right direction towards the best way to do it and the relevant opencv functions that would be really great.
Here is a picture describing what I want to do :
Thank you very much!
The approach that you need to follow, I think that it is quite easy and obvious:
and that's it.
That's a good idea but I'd like to avoid tracking the laser as much as possible for this step (because there might be multiple lasers). Would it be possble to only rely on frame combinations to do this? (each frame will only differ from the others at the point(s) where the laser(s) is (are) pointing).
@edgenk in this case here tracking equals to detect the laser and save the position coordinates through frames. That means, step 2 and 3 should be considered as the same action. Nothing fancy, it is the simplest tracking procedure that you can have. I do not think you can do it otherwise, without increasing the complexity of your project. Simple things, detect --> save position --> draw line.
