Have anyone any thoughts of a laser 3D scanner that scan in a triangular pattern. I think if you rotate the object around 3 times and between each pass you adjust the laser 60 degrees. You should be able to end up with a pattern that you can directly translate to a stl file?
It might be easier to understand with a small drawing…
Each scan would end up with the 3 points of the triangle at different spots than they were at before. For this reason, using 1 or more projected line and 2 cameras (or 1 camera and 2 or more projected lines) would be a better idea. The math becomes a case of angle and distance and height to get the 3D position of everything.
My thinking is to attack the problem with 3D printable object generation in mind, rather than just create a 3D object/file/point cloud. By using structured light in a triangle formation, the information would map directly to the stl file format.
My point was that once you change to a different camera angle, your points would not match up to what you had before.
