【摘要】 为了提高舰船的海上生存能力,各国都在研制新型更有效的舰船红外隐身方法。同时,对隐身效果的评价方法研究也成为红外隐身研究的重要部分。设计了基于图像分析的舰船红外隐身效果评价的基本流程,根据舰船在不同隐身状态下的图像特征,分别提取了温差、纹理和点特征三个特征参量,设计了相应的评价模型,分别基于红外图像中目标探测概率、目标与背景的纹理和点特征相似度价隐身效果。通过对三种评价方法的实验研究,讨论了这三种评价方法的适用范围。更多还原

【Abstract】 The more effective method of infrared camouflage are developed in order to improve the survive ability of the war ship in the sea.As a result,the study of evaluating the camouflage effect becomes an important part in studying the infrared camouflage.In this paper,the basic flowchart of evaluating the ship infrared camouflage effect based on the image analyzing is summarized.According to the different infrared characters of the ship image under the different camouflage methods,the temperature difference,texture feature and point feature are introduced as the evaluating parameter.Basing on the different evaluating parameters,figure out the detection probability,the texture difference between target and background,the point difference between target and background,as the evaluating standard.Experiment study of the three evaluating methods are carried out.The application range of each method is discussed.更多还原
