基于中心投影方程的多光电跟踪传感器跟踪测量模型

摘要

Multi-optical-electronic tracking systems are frequently used to track flying trajectory of airplane and weapons and airborne instruments in flight test. Observation angular revised formula is described, and then a processing algorithm with a set of image forming equations of the central projection for every tracking system based on the collinearity is presentsed. The equations will be linearised, and the optimal space rectangular coordinates of flying target is resolved by using the least-squared estimated approach. It is proved that the processing algorithm is an effective algorithm to get optimal accuracy in practice.%航空飞行试验中,经常采用多个光电跟踪测量系统对飞机及武器发射、航空装备性能鉴定等进行轨迹测量.根据光电经纬仪的仪器特点,首先对观测数据进行偏心改正,然后,利用共线条件建立多个光电跟踪测量系统中心投影方程组.经线性化后,在最小二乘准则下求解其最佳估计.飞行试验证明,该方法能够有效地提高观测数据处理精度.
