Real-time color stereo vision system for a mobile robot based on field multiplexing

Abstract

This paper discusses a stereo vision processing system which processes color and monochrome stereo video signals on a single vision processing board. Here, we propose a "field mixing" technique for multiplexing multiple video signals. A compact color stereo vision system based on this technique is developed for a mobile robot. This system can process multiple video signals simultaneously, and realizes flexible color stereo vision processing. In order to show the feasibility of this vision system, we installed it on our mobile robot, and implemented a correlation-based EZDF method for stereo tracking of an object. The experimental result of the tracking is shown.
