摘要
基于多台CCD电视经纬仪交会测量原理,深入分析了交会计算误差来源对系统测量的影响。针对离散落点和弹道采样点多目标数据,首先通过目标信息源合成来提高多目标数据录取率;然后,通过误差加权平均,融合处理测量数据,以降低多台电视经纬仪对同一组多目标的测量误差;进而,基于系统数据后处理,抽象多目标统计特性;借助系统熵标准,评估多目标信息融合效果。实验结果证明:该多台CCD电视经纬仪交会测量系统的多目标信息融合具有简单、有效、鲁棒等优点,并为相关多目标识别与定位领域内的应用提供了宝贵的参考价值。
<abstract>sed on the principle of CCD TV multi-theodolite intersection measurement, multitarget intersection problems are discussed thoroughly to reveal fusion aims. Then describe the multitarget types for intersection, after combination of information sources, measurement precision fusion and post system data processing, capacity of system multitarget measurement bettered much in respect of number processed, system entropy and system measurement error percent as shown by fusion results.
