I could see that with a lidar scanner, but the best ones that would support a high FPS capture are far more expensive than a set of motion capture suit, or even a proper red based camera setup.
Think something like a GeoSlam scanner.
You may be onto something though.
It’s probably worth trying to use a double lidar this way instead or on top of 2 cameras.
Having the actual distance to a specific point from the camera would incredibly improve accuracy…
Though I have not seen anything like this, I also haven’t looked into cinematic mocap in a long while. They could potentially have added something the like already…
