Hello,

Im working on 3D modeling and i have some overlapped objects in single image. I want to calculate the normal value for this objects. Is there a way to do it? How can i do it?

I think i caused a confusion. I want to calculate the value of the normal vector direction at each point of the point cloud data, i hope it is clearer for you

Normal directions are always relative to a vector (or plane), and that requires choosing at least two points: the point of interest and a point of origin. Isolated points do not have normals.
