目前的战场态势图所展示的作战要素数量大、信息杂、变化快,指挥员极易出现认知过载问题,难以实时准确把握战场热点。针对上述问题,提出了基于改进加权核密度估计法的战场态势热力图的构建展示方法,该方法通过指挥员需求选择、战场热点值计算、颜色表映射及态势图融合的流程,以符合人直观认知的热力图形式展示战场态势热点。示例演示及结果分析表明,提出的方法能够有效筛选态势信息,突出态势热点,具有较好的显示效果和应用前景。
The operational elements shown in the current battlefield posture diagram presents the characteristics of large quantity,miscellaneous information and fast changing,which makes it difficult to grasp battlefield dynamics accurately in real time and prone to cognitive overload problems. Aiming at the above problems,this paper proposes the construction and display-method of battlefield situation heat map based on improved weighted kernel density estimation method. The method displays the battlefield situation hot spot which conforms to the intuitive cognition of human by the way of commander's demand selection,the battlefield hot spot value calculation,the color table mapping and the situation map fusion. The analysis of example and result shows that the method presented in this paper can effectively screens the situation information and highlights the hotspot of the situation,which have excellent display effect and application prospect.
