A FPGA based high-speed binocular active vision system for tracking circle-shaped target

Abstract

With the development of digital image processing technology, computer vision technology has been widely used in various areas. Active vision is one of the main research fields in computer vision and can be used in different scenes, such as airports, ball games, and so on. FPGA (Field Programmable Gate Array) is widely used in computer vision field for its high speed and the ability to process a great amount of data. In this paper, a novel FPGA based high-speed binocular active vision system for tracking circle-shaped target is introduced. Specifically, our active vision system includes three parts: target tracking, coordinate transformation, and pan-tilt control. The system can handle 1000 successive frames in 1 s, track and keep the target at the center of the image for attention.
