Abstract:

In this project a complete 3D laser scanning system which uses a multibeam laser and a single camera is presented. The system is build from scratch and is aimed at small matchbox size object. The geometry of the scanner is adapted to fit an existing system which produces multispectral images of varies object and surface samples. The system as a whole can however easily be scaled to accommodate larger object and can therefore also be used for other applications.
