This software allows inexpensive 3d scanning of surfaces.

All you require is a video camera (e.g. webcam), a line laser (you will find suitable, cost-efficient laser modules in this shop), and a "corner" as background. You need faster scanning time? Just use a video projector instead of a line laser.
In order to obtain an all-around scan of your object, you simply create single scans from different directions; DAVID-Laserscanner is able to align and fuse the scans to a textured 360-degree-model.
The surface data can be exported to the well-known file formats .OBJ, .STL, and .PLY. This allows you to import them in 3rd-party software for further processing, e.g. milling or 3d printing.
