时间配准在多传感器数据处理中的应用

Registration and more time processing of sensor data

在应用多传感器进行数据采集的系统中,需要对源于同一目标、同一时刻的不同传感器数据进行融合处理,但由于各传感器的工作方式、传输时延等原因造成数据不同步的问题。因此,在对多传感器数据融合前,应该对多传感器数据进行时间配准。本文提出了采用内插、外推时间配准法解决多传感器时间配准问题,通过仿真验证,该算法可以较好的解决问题。

In multi-sensor data fusion system,Since the sensors work,the reasons for delay,etc.Fusion center received from the sensor measurement data is asynchronous.Data fusion from the need for the same goals,the same time the different sensor data processing.As a result,multi-sensor data fusion of the former,should be multi-sensor data registration time.In this paper,two time registration algorithm,and compared
