基于HAUSDORFF距离的红外假目标客观评价方法

A Method of IR Camouflage Target Evaluation by Using Hausdorff-Distance

在伪装工程防红外假目标示假效果的评价中,HAUSDORFF距离经常被用来作为一个评价指标。通过研究发现,过去使用HAUSDORFF距离评价的图像时,没有考虑图像分辨率和图像变化面积对评价结果的影响,因此未能给出基于HAUSDORFF距离的量化的客观评价标准。通过分析HAUSDORFF距离用于比较的机理,分析了影响得到客观评价标准的因素,设计了克服影响因素的方法,并通过仿真试验,证明了此方法的有效性。通过观察者群体进行观察试验,制定了基于HAUSDORFF距离的客观评价红外目标图像示假效果的评价标准。

Hausdorff-Distance was used in IR camouflage target evaluation. By our study, effect of the image resolving power and changing proportion on evaluation were not considered at past, so there was not get a impersonality standard for IR camouflage target evaluation. The factors of getting the impersonality standard were analyzed through Hausdorff-Distance theory. We designed the method of conquering, and results showed it was effective. At the end, we get the impersonality standard for IR camouflage target evaluation through experience.
