| 摘 要： | 时间同步是多传感器协同工作的基础，船载岛礁综合测量系统中的激光扫描仪系统和多波束测深系统需要与G PS 实现时间同步，针对激光扫描仪本身不具有时间同步功能，提出一种G PS脉冲与网络通信相结合的时间同步方法，方法实现简单并且同步误差较小。实验证明：利用所提出的方法多传感器信息可取得良好的融合效果。

| Abstract: | Time synchronization is the basic of multi-sensor collaborative work ,laser scanner system and multibeam bathymetry system of shipborne island comprehensive meas-urement system need to realize time synchronization with GPS .For laser scanner does not have time synchronization function ,this paper proposes a time synchronization method that combining GPS pulse with network communication .This method is simple to realize ,and it can provide the required accuracy of time synchronization .T he experiment proved that multi-sensor information fusion can achieve good results using the proposed method . |
