Trinocular Spherical Stereo Vision for Indoor Surveillance

Abstract

Stereo vision based sensors are widely used for indoor surveillance applications. Besides the demand for increasing performance the reduction of the overall number of sensors is the crucial issue. The central goal is the reduction of complexity and overall cost of the system. One opportunity is to use wide angle view based or even Omni directional stereo vision sensors. We present a powerful approach which uses three Omni directional cameras in order to compute full hemispherical depth information. By employing this, we can cover a complete room using only one sensor.
