摘要
移动对象追踪和更新技术,是影响移动对象数据库性能的重要因素。本文提出了一种基于移动向量和船舶导航信息的移动对象信息更新机制。这种方法通过对船舶航线的建模,设计了自动化的移动对象信息更新算法。通过仿真和实验,证明了本文提出的方法与传统的真实航线信息更新方法相比,具有更好的性能表现,能够在较低的系统开销下,实现较高的精确度。
The motion object tracking and update technology,is the important factor affecting the moving objects database performance. This paper puts forward a kind of moving objects information update mechanism based on moving vector and ship navigation information. This method is based on the modeling of ship route,having an automatic moving object information update algorithm. By simulation and experiment,this paper demonstrates that the proposed method compared with traditional real track information update method,has better performance,and can achieve the lower overhead as well as a higher accuracy.
