针对无人机对目标进行匹配定位过程中,面临图像旋转变化及视角尺寸过小导致的图像特征提取困难等问题,提出了一种融合候选区域检测与SE-Hardnet特征提取网络的无人机目标图像匹配算法.通过Edge Boxes算法检测候选区域,结合SE-Hardnet网络进行特征提取,实现了目标图像的精确匹配.实验结果表明,所提算法在图像发生角度、尺寸变化时,具有更高的匹配正确率和鲁棒性,在近距离条件下图片数据集中的匹配正确率比现阶段图像匹配算法高 8%～11%.为无人机目标定位提供了一种可行和有效的手段.
UAV image target matching algorithm based on SE-Hardnet network
In order to address the problems in target matching and localization by unmanned aerial vehicles(UAVs),such as the difficulties of feature extraction caused by image rotation variations between UAV images and target reference images and small image sizes from the UAV perspective,a UAV target image matching algorithm combining the candidate region detection and the SE-Hardnet feature extraction network was proposed.The Edge Boxes algorithm was used to detect candidate regions,and the SE-Hardnet network was employed for regional feature extraction,for precise target image matching by comparing feature similarities.Experimental results demonstrate that the proposed algorithm exhibits higher matching accuracy and robustness under the condition of image angle and size variations.In close-range scenarios,the matching accuracy within the image dataset surpasses that of current image matching algorithms by 8%to 11%,providing a feasible and effective solution for UAV target positioning.
