Abstract :
Omni-directional sensors are useful in obtaining a 360° field of view with a single lens camera. Fiala et al. (1996) described an approach to designing a stereo panoramic imaging system using a double-lobed mirror surface. This paper extends our earlier work by relating 3D points to the 2D projections obtained by our system. Applications of the system include surveillance and security, automatic and passive monitoring for peace-keeping tasks, and fast detection of corrosion and deposits in pipelines and industrial containers. Experimental results verifying the mathematical modeling are also provided
