Using ditance Transform to obtain movement of the camera

asked 2018-03-06 11:14:41 -0500


I'm trying to implement an application where the camera is pointing upwards towards the ceiling. I want to mount the camera fixed in a robot so it will be constantly in parallel with the ceiling. I am planning to use distance transform in order to obtain the movement of the mobile Robot (and camera) at every moment. I have been able to get the distance transform of a single image but I have no clue on how to extract distance from the comparison of two consecutive images (in grey scale after having applied the distance transform). Any clue on how to perform such actions?

to my knowledge a distance transform calculates distances between black and white pixels whithin a single image . how would that be related to movement, at all ?

rather have a look at optical flow, or something like this
