基于AHP方法的战场目标三维伪装效果评估

Evaluation of three-dimensional camouflage effect of battlefield targets based on AHP method

针对战场目标伪装效果评估视角单一、主观性过强等问题,基于层次分析法(AHP)和航迹发现概率对战场目标三维伪装效果进行多视角评估研究。在利用无人机倾斜摄影技术对战场目标进行三维建模的基础上,模拟无人机航线侦察获得多视角侦察影像;综合提取影像中目标与背景的亮度、颜色、纹理等8个评估指标并计算相似度,采用AHP建立单视角特征相似度评估模型;基于航迹的目标发现概率模型,计算多视角目标相似度权重,构建了战场目标伪装效果多视角评估模型。通过案例分析,多视角评估方法能够实现战场目标伪装效果多角度、连续性客观综合评估。

To solve the problems of a single perspective and too strong subjectivity in the evaluation of battlefield target camouflage effect,this paper evaluates the three-dimensional camouflage effect of battlefield targets from multiple perspectives based on Analytic Hierarchy Process(AHP)and track discovery probability.On the basis of 3D modeling of battlefield targets by UAV tilt photography technology,multi-view reconnaissance images are obtained by simulating UAV route reconnaissance.Eight evaluation indexes,such as brightness,color and texture of the target and background are comprehensively extracted from the images and the similarity is calculated.AHP is used to establish a single-view feature similarity evaluation model.Based on the target discovery probability model of the track,the similarity weight of the multi-view target is calculated,and the multi-view evaluation model of battlefield target camouflage effect is constructed.Through case analysis,the multi-perspective evaluation method can continuously realize objective and comprehensive evaluation of battlefield target camouflage effect from multiple perspectives.
