An active vision system for object gazing
Bing Liang, Bingrong Hong · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2002
Active vision has been an important research area in recent years, which refers to the ability to move an image acquisition system in a controlled manner. This paper intends to introduce the active vision system with the autonomous robot competition in the background. We present some characteristics of the human oculomotor system in active machine vision system: smooth pursuit and saccade. Beside of this, zoom tracking was used to continuous adjustment of a camera's focal length to keep a constant sized image of an object moving along the camera' optical axis. Some experiments based on these technologies show the efficiency for gazing the ball in the robot competition.
