EHP - 3D Scaning Project
It's a project involved with 3D Scan.
Ideas And Thoughts
Generally,I showed the reason why we need 3D scan and also different manners to achieve 3D scan. I compared with these manners and choose David Laserscanner to be my platform. Compared with others, it is cheap(with free version and the professional version costs 291Euro while some cost almost 40,000Euro but offer the same quality), very fast(compared with photo-based method),high precision(While pointcloud-based technique can only offer a rather rough result ) and it can scan a large range of subjects from very large object to tiny small things if using the motor scanning.In conclusion, David system is almost the best choice.I would build a system to use the stepper motor controlling the laser to realize the 3D scan.

How To & My Process
Note: For the camera, In most cases, DAVID works in lowlight conditions to get a clear contrasted laser line. So the cam should be able to handle this. High light sensitivity and as little noise as possible is recommended. For the laser line, laser line should be as thin as possible –> focusable; as bright as possible; perfect straight line and a red or green laser if you use a color camera.
