Abstract

A video-rate stereo machine is a dedicated hardware device for range measurement. It can generate a dense range map and an associated intensity image at 30 frames per second. This paper shows a camera geometry correction module which is designed and implemented as an circuit module to improve the performance of the stereo machine. The main functions are input-image transformation and selection of candidate points of a corresponding point. The stereo machine integrated with the camera geometry correction capability not only corrects camera geometry and lens distortion, but also operates with multiple cameras positioned arbitrary, resulting in an improved measurement accuracy.
