提出了一种新的评价假目标红外示假效果的方法。该方法首先采用Harris算子提取军事目标及其相应假目标的红外图像的特征点,然后采用Hausdorff距离计算所提取的特征点集之间的Hausdorff距离。该距离越大,说明假目标与真目标相差越大;该距离越小说明真、假目标越相似,也就是说假目标的红外示假效果越好。
A new method of evaluating the fake target’s false impression is proposed. In this method, the Harris operator is used to extract the feature points of the infrared image of the military target and its corresponding fake target. Then the Hausdorff distance between the extracted feature point sets is calculated by using the Hausdorff distance. The larger the distance is, the bigger the difference between the false target and the true target is. The smaller the distance is, the more similar the true and the false targets are. That is to say, the false target is better.
