摘要

火星探测器在着陆过程中面临严峻的火星地理环境

对特征提取及特征匹配的性能造成严重影响.为此

提出了一种多特征融合的撞击坑特征选择方法.该方法先对撞击坑用多种特征检测子进行可重复性评价得出综合性能最好的AKAZE特征检测子

然后以AKAZE特征检测子为基础

通过查全率-查错率(recall vs.1-precision) 曲线来对多种特征描述子评价

最后将其中性能较好的一种或几种特征结合

对撞击坑地貌进行特征提取及匹配

选择匹配性能最好的一组作为撞击坑匹配定位的特征.实验结果表明

用该特征选择方法进行撞击坑匹配与传统的SIFT特征匹配相比

匹配正确率提高了8%左右.

Abstract

Mars spacecraft facing severe Mars geographical environment in the landing process.Performance of feature extraction and feature matching have been seriously affected.To solve this problem

a feature selection method based on multi-feature fusion is proposed.Firstly

the AKAZE feature detector with the best comprehensive performance is obtained by using the repeatability evaluation of the feature pits.Then

based on the AKAZE feature detector

the recall rate 1-precision curve is used to evaluate the feature descriptors.Finally

one or several features with better performance are combined to extract and match the features of the craters

and the best matching performance is selected as the feature of positioning for crater.Experimental results show that compared with the traditional SIFT feature matching

the matching accuracy is improved by about 8%.
