摘要
为了解决机栽光电跟踪系统高准确度陀螺平台成本高、难度大的问题,在深入分析视轴晃动与图像关系的基础上,利用机栽平台的特点,确定了图像运动矢量的关系,忽略了次要因素,进一步简化了运算,提高了算法的准确度.将此算法应用于某歼击机的图像进行稳定试验,结果表明:该算法具有快速、稳定等优点,能够实现实时准确地稳定歼击机图像序列.
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.
