Hey guys!  
I have a task to scan an object with line laser and then to create point cloud of the hight and length of obsticle of laser. (Just obsticle of horizontal moving laser line)  
I need a path of courses and learning material to start from zero as I have to openCV knowlege.  
thanks in advance

you’ll need a solid foundation in computer vision.

this project involves low level image processing, 3D geometry, camera calibration, and you should also approach this as creating a _mesh_, not just a point cloud
