Extracting depth by binocular stereo in a robot vision system
New generation of robotic systems will operate in complex, unstructured environments utilizing sophisticated sensory mechanisms. Vision and range will be two of the most important sensory modalities such a system will utilize to sense their operating environment. Measurement of depth is critical for the success of many robotic tasks such as: object recognition and location; obstacle avoidance and navigation; and object inspection. In this paper we consider the development of a binocular stereo technique for extracting depth information in a robot vision system for inspection and manipulation tasks. Ability to produce precise depth measurements over a wide range of distances and the passivity of the approach make binocular stereo techniques attractive and appropriate for range finding in a robotic environment. This paper describes work in progress towards the development of a region-based binocular stereo technique for a robot vision system designed for inspection and manipulation and presents preliminary experiments designed to evaluate performance of the approach. Results of these studies show promise for the region-based stereo matching approach. 16 refs., 1 fig.
