HOPIS: Hybrid Omnidirectional and Perspective Imaging System for Mobile Robots

open access: yesSensors, 2014
In this paper, we present a framework for the hybrid omnidirectional and perspective robot vision system. Based on the hybrid imaging geometry, a generalized stereo approach is developed via the construction of virtual cameras. It is then used to rectify
