摘　　要：无人机航迹的实时显示是无人机遥感系统进行实时监测工作必不可少的功能之一。本文分析了Ma-pObjects控件动态层的特点,研究了基于MapObjects控件的动态数据显示常用算法,并指出该算法在无人机航迹实时动态显示应用上存在的问题。在此基础上提出了新的算法,详细阐述了该算法的核心思想及实现流程。最后在MapObjects控件和MS Visual Studio.Net开发环境下对相关实现细节进行了描述,并分析了该功能的性能状况。The real-time trajectory display of UAV is one of necessary functions for the remote sensing UAV system. This paper analyzes the characteristics of the tracking layer in MapObjeets and the disadvantages of the general method based on MapObjects for dynamic data display, especially in the UAV real-time trajectory display. Then, the paper provides a new method of UAV real-time trajectory display. Finally, it describes the details of the new method under the development environment of MS Visual Studio. Net and MapObjects, and analyzes its performance.
