Hello everybody, i working in a project of 360º laser 3d scanning in a turntable (Camera and Laser dont move and the distance to turntable is always the same), but have some questions which i don't find answers for them, then i expect find here.

1º How is the process for detect the position of each point in a captured image ? Like the example below ( vertically contours), but with monochrome, how the process will know which the white stripe/contours is a place who you need place the points ?

2º How is attached each point in a tridimensional space ? Example: p(0,2,7); p(2,6,3);...;.

Thank for Help. Sorry for anything.
