摘要
对于多个动目标,依其空间分布,鈓用近邻方法,实施动目标的多分辨率显示控制。研究的目的是将动目标的时空数据可视化,显示出具有全局综合和局部放大视觉效果的可视化画面。首先针对动目标的时空离散数据的特点,提出对动目标的近邻分群准则和聚合算法;然后结合动目标的轨迹特点和目标编队跟踪思想,提出轨迹聚合的近邻分群准则和聚合算法。实现了基于近邻方法的动目标多分辨率轨迹聚合的显示控制。在原型系统中实现了多分辨率显示控制,在不同分辨率下,可示意性描画出分散的多编队动目标分布。取得了全局综合和局部放大的视觉效果。
In order to display disperse formations clearly an d to get visual effect of total integration and partial multi-plication image,mu lti-resolution display control method based on nearest distance clustering for real time moving objects is prompted.According to the characteristics of real time disperse tracking objects,nearest clustering method is presented and impr oved.Rule of tracking clustering is determined.Multi-resolution display contr ol for real time moving objects of disperse formations is implemented and proce ssing of display control is showed in prototype system.Total integration and pa rtial multiplication image is obtained.Distribution of multi disperse formation is implied on different resolution.
