We present here a new approach to 3D scanning whose key features are portability and flexibility. The system consists of a pair of standard video cameras, a laser pointer, and a real-time shape recognizer that lets the laser spot be detected with high reliability and accuracy. The choice of manual scanning allows the laser beam to be selectively directed and enables more polygons to be collected in the most difficult surface regions. It does not use any mechanical scanning systems, making it easy to set-up. The video cameras are located according to the orientation of the object to be scanned, allowing maximum flexibility in the scanning procedure.
