A practical stereo vision system
نویسنده
چکیده
We have built a high-speed, physically robust stereo ranging system. We describe our experiences with this system on several autonomous robot vehicles. We use a custom built, trinocular stereo jig and three specially modified CCD cameras. Stereo matching is per$ormed using the sum-ofsum-of-squared differences technique.

A Region-Based Approach to Stereo Matching for USAR
Stereo vision for mobile robots is challenging, particularly when employing embedded systems with limited processing power. Objects in the field of vision must be extracted and represented in a fashion useful to the observer, but methods must also be in place for dealing with the large volume of data that stereo vision necessitates, in order to maintain a practical frame rate. We are working wi...

متن کاملReal-Time Target Localization and Tracking by N-Ocular Stereo
In recent years, various practical systems using multiple vision sensors have been proposed. In this paper, as an application of such vision systems, we propose a real-time human tracking system consisting of multiple omnidirectional vision sensors (ODVSs). The system measures people’s locations by N-ocular stereo, which is an extension of trinocular stereo, from omnidirectional images taken wi...
