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

• 

Currently I am stilling waiting the red line laser shipping to me. What I achieved is using the arduino and a motor diver to control the stepper more smoothly compared with the one without the motor driver. I am looking for a stepper with gears built-in, Or I need to build the gears myself. Also I need to build a V3 Pattern background for the camera calibration and realize the synchronization of the David software and the stepper motor through COM port.
