单张影像月球着陆区选取技术

A Lunar Landing Area Select Method Based on Single Image

提出了一种基于单张影像的月球着陆区快速选取方法。首先在分析月面光照成像模型基础上,提出了一种新的改进的光照模型和一个新的约束条件,采用明暗恢复形状(SFS)算法得到月面3维形貌;然后综合影像和得到的3维形貌,计算月面地形粗糙度,采用两步筛选的方法,选取着陆区域。实验结果表明,该方法较好地实现了着陆区的选取。

A fast method to select landing area based on single image was proposed.Firstly,the lighting condition on lunar surface was analyzed,a new lighting model and a novel constraint was proposed.The 3-D information of lunar surface can be obtained by adopting shape-from-shading method based on the improved lighting model.Then,according to the image and 3-D information,roughness of the lunar surface can be calculated,and landing area is selected by two steps select.The experiment result proved that the method was able to select the landing area correctly.
