R200 realisense camera, the three-dimensional coordinates of a point on the 3D scanning model is the camera as the origin of it? Also, how do I calculate the distance from the point to the camera on the model?

The camera sees a digital image made of pixels. From this you can:

- Find out the screen coordinates of a point on the digital image using the ProjectCameratoColor instruction.

- Find out the real world coordinates of a point on the digital image using the ProjectCameraToDepth instruction.
