    摘要:

    传统的交会定位公式是在假设飞行目标为点目标的前提下推导的理想模型公式,而实际两台经纬仪观测同一目标时其主光轴并不交于同一点,这就会带来较大的模型系统误差。因此,提出了基于融合动态加权的光电经纬仪交会定位方法,详细介绍了该方法的模型以及确定融合动态加权系数的原则,并采用仿真数据,对本文方法和传统方法的定位精度进行对比分析,经实验验证,本文方法精度高于传统方法,具有较大的工程实践价值。

    Abstract:

    The traditional intersection positioning formula is from the ideal model that assuming the flight target is a point. But when two thedolites observing on the same target, their principal optical axis always can not intersection in the same point, and this will cause the model system error. Therefore, in this paper, the photoelectric theodolite intersection positioning method based on fusion dynamic weighting is proposed; the model of this method and the determination principles of the fusion dynamic weighting coefficients is introduced in detail; then, using the simulation data, the positioning precision of this method and the traditional method is compared; finally, analysis of the experiments showed that, the method proposed in this paper is better than the traditional method in positioning accuracy. So this new intersection positioning method has a high value of engineering practice.
