DAVID-Laserscanner is a freeware software application for 3d laser range scanning. All you need to build a 3d scanner is a PC, a camera (e.g. a webcam), a background corner and a laser that projects a line onto the object you want to scan. So everyone can use it to scan objects without high costs; this is the big advantage over commercial solutions which are rather expensive.

The concept has been developed by the computer scientists Dr. Simon Winkelbach, Sven Molkenstruck and Prof. F. M. Wahl at the Institute for Robotics and Process Control, Technical University of Braunschweig, Germany and was published as a paper at the German Association for Pattern Recognition.

The object you want to scan has to be put in front of a known background geometry (e.g. into the corner of a room or in front of two planes with an exact angle of 90?).

The camera of course has to be pointed towards the object. The special thing about this solution is that you freely hold the laser in your hand, "brushing" the laser line over the object.

Meanwhile the computer automatically calculates 3D coordinates of the scanned object surface. See our gallery to get an impression of the software.

To obtain a complete 360 degree model of your 3d object, we have developed DAVID-Shapefusion that automatically "puzzles" together the laser scans made from different sides.
