Design And Implementation Of The Floating Platform Attitude Measurement System Based On Image Processing Technology

The firing control system with floating-observation-platform can raise air defense system's low level battle-capability considering recovery of our country. The orientation of floating-observation-platform is very important to this system.With that problem, the measurement system of floating-observation-platform's attitude angle based on image processing is designed, which is a part of a firing control system with floating-observation-platform. The system is designed to measure the platform's attitude angle accurately that is very important to the orientation of floating-observation-platform and provide the firing control system with important target status information.High-speed image processing platform, based on DSP and CPLD/FPGA, is firstly introduced in this thesis. DAM6416P, based on TMS320C6416 and used in the tracking sub-system, is one of this kind of platforms.After preprocessing the sampled real-time image sequences, a series of position data can be got by combining thresholding with Ostu algorithm and beaconing contour tracking.And then, analyzing these data with the ubiety of beacon, we can find each beacon's position on screen.Sometimes,the platform may shake acutely,and the beaconing can leave the eyeshot of CCD. So each orientation method in different scene is introduced in this thesis. Then the analytic theory and approach of platform's attitude angle are discussed.The components and structure of the measurement system are also discussed. Finally, the experimental result is presented.
