Intelligent vision-based detection and ranging system and method

摘要

An intelligent vision-based detection and ranging (iVidar) system consists of at least four cameras to form at least two stereo vision systems. The first pair of two cameras forms a first stereo vision system with a field of view A1 and has a baseline B1. The second pair of two cameras forms a second stereo vision system with a field of view A2 and has a baseline B2. Where B2 is greater than B1 and A2 is smaller than A1. One of the preferred configurations for the current invention is to mount the second stereo vision system field of view A2 to cover a perspective vanishing point in the along-track direction.
