摘要
基于图像建立三维月面地图对于月球车任务规划、导航控制具有重要意义。本文提出一种基于参数化轮廓结构特征匹配的月面三维重建方法,该方法从月面立体图像中提取特征物的轮廓特征,通过参数化轮廓特征匹配恢复特征物的三维信息,从而建立三维月面地图。本文以Apollo 15登月计划的着陆区域为例,建立了一个三维月面地图。
Building the 3-D lunar map from lunar images is of great importance for the mission planning and navigation of the lunar rover. In this paper, based on the matching among the parameterized contour features, a 3-D lunar surface reconstruction method is proposed. First, the contour feature of the characterized object is extracted from the lunar surface stereo-images, then the objects＇ geometric information is inferred according to the correspondence between the parameterized contour features. Therefore, a digital lunar map is constructed. The modeling method is demonstrated through the 3-D reconstruction of the lunar surface about the landing site in the Apollo 15 program.
