| Abstract: | In order to redeuce the cost and machining difficulty of gyroscope in airborne electro-optical traking system, the correlation between boresight perturbation and image was analyzed. Basde on the analysis,the estimation of image motion was found by using the inberent characteristics of the airborne platform. When subsidiary factors were ignored, algorithm was simplified and higher precision was gained. The algorithm was applied to vision tracking system of a fighter plane . The result shows that tracking ability is more stable and faster than ever before. Using algorithm, real time image sequences tracking are realized with high stability. |
