About the number of "utils.nValidElement"?

Hi @fangchangma ,
In your code, you regard the number of all pixels as "utils.nValidElement" when evaluation AbsRel and others, rather than the number of Lidar-point. Actually, I want to know whether this is a general guidelines?

Hi @godman2016 ,

nValidElement, computed as the number of non-zero points in the target image, is in fact the number of lidar measurements on the image plane.
