Pylascan is a set of python scripts to assist in laser triangulated 3d scanning
Scanning is done by controlling an arduino connected to a stepper and two line-lasers, combined with a webcam to take pictures. The stepper supports up to 400 steps, for each step three pictures are taken, resulting in two different point clouds with color information ( one picture is used to scan for colors on the scanning object ).
These two point clouds are then merged, scaled and a pretty rough algorithm is used to directly build a triangle mesh from the pointcloud data, for efficient post-processing in meshlab. Model after poissoin reconstruction and transferring the vertex colors

Altough all of the code in this repository is my own work, i've drawn on these projects for ideas and understanding the math involved:
Also I would like to thank Miguel Jimenez Gimenez for writing the arduino code and constructing the initial prototypes for the scanner in Fablab Amsterdam
