Mobile Sensors for Security and Surveillance
Zhigang Zhu · Journal of Applied Security Research · 2008
A stereo mosaic representation has been developed for fusing imaging data captured by sensors (cameras) in motion. In addition to providing a wide field of view, the multiperspective mosaics with various oblique views represent occlusion regions that cannot be achieved by using stationary sensors. One or multiple stereo pairs can be formed from mosaics with different oblique viewing angles and thus can be used for 3D viewing and 3D reconstruction. This approach has been applied to a number of important security and surveillance applications, including airborne surveillance, ground vehicle navigation, under-vehicle inspection, and 3D gamma-ray cargo inspection.
