Abstract
With the wide application of photoelectric equipments in military and civilian areas such as aviation, arms control etc., high-speed image acquisition and real-time processing attracted more and more attention. In order to acquire the accurate position information of beacon in photoelectric tracking system quickly, a embedded high frame-rate CMOS beacon position system based on davinci technology was presented. This system could detect the beacon and acquire its position information with high-speed. Using CMOS sensor MT9M001 as detector, this system could capture image and calculated centroid at different speed. It used centroid algorithm based on double gate object tracking strategy to acquire the spot centroid and can process image of 600x550 resolution at 130fps. The system was characterized by dynamic reconfiguration and high efficiency of computation. It could be applied in photoelectric tracking and space laser communication.
