复杂背景条件下目标自适应伪装光学效果评估方法

针对单一背景下的伪装评估方法难以度量自适应伪装目标在多背景中的综合伪装效果，提出一种自适应 伪装目标在多背景下的光学伪装效果评估方法。选取几种典型背景，对每种背景下目标的光学伪装效果进行评估； 依据星载高光谱图像对目标活动区域内的地物进行分类，确定区域中每种典型背景的面积占比；以每种背景所占比 例作为该背景下评估结果在综合评估中的占比，对各典型背景评估结果加权，得到复杂背景下的综合评估结果。实 验结果表明：该方法量化了多背景下的综合伪装效果，其评估结果较传统的评估更客观全面，更符合目标在多背景 中活动的实际情况。

Evaluation Method of Optical Effect of Adaptive Camouflage of Targets Under Complex Background Conditions

Since it is difficult to measure the comprehensive camouflage effect of adaptive camouflage targets in multiple backgrounds by using the camouflage evaluation method in a single background, a method for evaluating the optical camouflage effect of adaptive camouflage targets in multiple backgrounds is proposed. Selecting several typical backgrounds, evaluating the optical camouflage effect of the target under each background, classifying the ground objects in the target activity area according to the satellite-borne hyperspectral image, and determining the area proportion of each typical background in the area; The proportion of each background is taken as the proportion of the evaluation results in the comprehensive evaluation under the background, and the evaluation results of each typical background are weighted to obtain the comprehensive evaluation results under the complex background. The experimental results show that the method quantifies the comprehensive camouflage effect under multiple backgrounds, and its evaluation results are more objective and comprehensive than the traditional evaluation, which is more in line with the actual situation of the target''s activities in multiple backgrounds.
