The dataset used in the example is taken from the TUM RGB-D Dataset. According to the documentation
The depth images are scaled by a factor of 5000, i.e., a pixel value of 5000 in the depth image corresponds to a distance of 1 meter from the camera, ...
In order to find 3d feature points coordinates in world, we divide depth by 5000. What is the reason for that? What are the units of 3d coordinates (mm, cm, m) ? I want to implement PnP algorithm using Intel RealSense D435 but I am not sure how much it should be divided by?
