摘要:
为了解决常用插值方法在AIS(automatic identification system)轨迹插值上存在精度差异,在拉格朗日线性插值、三次样条插值 、时间插值等几种常用插值方法的基础上,提出一种新的插值方法。新方法通过连续两点间航向差值大小,将轨迹分为直线和曲线两种,并结合线性插值和航速航向,以提高插值精度。最后以实际AIS轨迹数据进行插值实验。研究结果表明,与其他常用插值方法相比较,新方法在插值效果上更接近原有轨迹。
Abstract:
The commonly used interpolation method different levels of precision in the AIS (automatic identification system) trajectory interpolation.Several common interpolation methods are introduced,and a new interpolation method is proposed.The new method divides the trajectory into two types,straight line and curve,according to the difference of course differences between two consecutive points,and combines linear interpolation and speed course to improve the interpolation precision.Finally,the interpolation experiment is carried out with the actual AIS trajectory data,and the effects of other common interpolation methods are compared.The results show that the new method is closer to the original trajectory in terms of interpolation effect.
