摘要/Abstract

摘要： 为了让用户从海量的空间目标态势信息中准确、高效的感知所需信息,引入多尺度表达思想,在多方面分析空间目标态势表达影响因素的基础上,建立多尺度表达模型,并结合Voronoi图实现空间目标多尺度表达。最后通过实验验证了模型和方法的有效性,结果表明：该方法可以有效控制空间目标态势表达的信息量和各层次态势信息的详略程度,满足空间目标表达的清晰性和易读性的要求,提高空间目标表达效果。

关键词: 空间目标, 多尺度模型, 多尺度表达, Voronoi图

Abstract: To allow users to acquire accurately and efficiently information, which they need, from vast amounts of space situational information, the thought of multi-scale expression was used, on the basis of analysis of various factors, which influenced space objects expression, multi-scale expression models were established, space objects multi-scale expression was achieved combined with the construction of the voronoi diagram. The experiments were done to verify the validity of the model and methods, the results show that: this method can largely control the amount and level of detail of information, can meet the requirements of clarity and legibility of space situational expression, and can effectively improve the effect of space objects expression.

Key words: space objects, multi-scale model, multi-scale expression, voronoi diagram
