Hi, about usage of kinect2, I was checking how to calculate the distance of a joint from floor.
As far as i know it can be calculated knowing the floor plane representation ( FloorClipPlane), is there any node of controbution retrieving that value ?
I know it can be just measured manually, but I was exploring Kinect2 nodes, and I found out camera intrinsincs, wondering if it can be useful for this operation.
My idea is to use the following formula once i know sensor phisycal height :
I would go for the Points2Vector.2d node, if you work in a patch. If you want to write your own plugin in c#, the kinectv2 SDK implements a funktion that calculates the center of the floor plane. Sry I don’t do a lot of vector calculation in c#, for sure someone else here is better at Math :)
Kinect SDK implements, as I said, the whole description of the plane, included the inverse height, aka the sensor phisical height.
So, using the SDK would be better to retrieve that’s height and calculate the distance 3d of a point ( joint ) from the plane.
The solution is known not a secret to research, my question was more about…did somebody ever used the distance of a kinetc joint from the plane ? :)
