A range imaging system, and a method for calibrating such a system are based on the principles of projective geometry. The system comprises four subsystems: (1) a laser and a cylindrical lens or vibrating mirror for producing a planar beam of light; (2) an electronic camera equipped with a lens and an...http://www.google.com.au/patents/US4979815?utm_source=gb-gplus-sharePatent US4979815 - Laser range imaging system based on projective geometry
