Intelligent tracking method of ship’s navigation track information in satellite navigation system

针对当前船舶航行轨迹跟踪误差大的问题,为了提高船舶航行轨迹跟踪的精度,提出基于卫星导航系统的船舶航行轨迹智能跟踪方法。首先采用卫星导航系统对船舶航行相关信息进行采集,然后采用高斯混合模型对船舶航行轨迹进行检测和智能跟踪,最后其他的船舶航行轨迹跟踪方法进行对比测试。结果表明,在相同实验环境下,本文方法的船舶航行轨迹跟踪误差远远小于对比方法,船舶航行轨迹跟踪实时性能也得到较大的改善,解决船舶航行轨迹跟踪过程存在一些难题,具有更广泛实际应用范围。

In order to improve the accuracy of tracking information of ship’s navigation trajectory,an intelligent tracking method of ship’s navigation trajectory information based on satellite navigation system is proposed.Firstly,the navigation information is collected by the satellite navigation system,then the navigation trajectory information is detected and tracked intelligently by Gaussian mixture model,and finally other tracking methods are compared and tested.The results show that under the same experimental environment,the tracking error of ship’s trajectory information in this method is much smaller than that in the comparative method,and the real-time performance of ship’s trajectory information tracking has been greatly improved.There are some difficulties in solving the process of ship’s trajectory information tracking,which has a wider range of practical applications.
