Motionless wide angle laser scanning for object detection and multi-spectral discrimination

Terrestrial laser screening has become an essential tool in may industries requiring digital three-dimensional reconstruction of an object or scene. These include civilian applications such as surveying, automobile collision avoidance, 3D animation modelling, mobile robot navigation, industrial inspection, traffic monitoring and more. The military has also employed laser scanning technology for projectile guidance, gun fire ranging measurements, surveillance, sattelite and missile tracking and target recognition. In the last decade, terrestrial laser scanning has found new use as an active optical sensor for indoors and outdoors perimeter security. In the intrusion detection field, laser scanning holds many advantages over conventional passive infrared sensors and active post-to-post laser sensors. Its key features are the ability to determine the intrusion size, speed and precise location. Nuisance and false alarm rates are also minimized since ignoring objects based on speed and size is possible.
