A Note on Depth Estimation from Stereo Imaging Systems

Abstract

The depth extractionfrom visual information is one of underpinning research area of robotics andthere is a growing trend in development of autonomous and intelligent systems forreal-life applications. These unmanned systems need reliable depth estimations inorder to move in three-dimensional space, autonomously. Inspiring frombiological vision systems, stereo imaging systems promise a solution for the depthestimation from binocular image pairs provided by stereo cameras. One of themajor problems in the depth estimation from the stereo image pair is low depthresolution. This paper discusses the depth resolution problem and presents a depthresolution analysis for stereo imaging systems.
