| 摘 要： | 在分布式多传感器融合系统中,各局部传感器接收到量测信息后,经关联得到局部轨迹,再将该轨迹送入融合中心进行处理.本文对一种伪实时场景监控系统,实现轨迹关联后,提出根据固定场景量测误差的先验知识,计算轨迹修正函数,以获得更好的轨迹融合结果.实验结果表明,该算法能够实现伪实时的轨迹关联与融合,充分考虑了场景所造成的量测误差,融合效果优于加权融合算法.

| Abstract: | In a distributed multi-sensor fusion system,the local sensor received measurement information,got tracks by local association and sent into the center for processing.A method of track association in a pseudo-real-time monitoring system is presented.It gets better integration results by correction function that is got through a prior measurement error knowledge of the regular scene.Considering measurement error in scene,the algorithm can achieve pseudo-real-time track associated and track integration,and be ... |
