Internal morphology point clouds of lunar pits

This archive contains point clouds showing the internal geometry of six pits on the Moon. These point clouds were generated via manual feature matching in "oblique stereo pairs": pairs of Lunar Reconnaissance Orbiter Narrow Angle Camera (LROC NAC) images at two different off-nadir angles observing one wall of a pit under similar lighting conditions. These images have pixel scales of ~0.3-2.2 m/pixel, allowing the creation of point clouds with point spacing on the order of 5-10 m, depending on the density of identifiable features on the pit walls. The manually-generated point clouds from multiple stereo pairs have been merged together, and aligned to and merged with dense digital terrain models (DTMs) from more nadir-looking NAC stereo images where available, to produce point clouds that cover the upper walls, floors, and immediate surroundings of the pits. For a full description of the processing method, see Wagner and Robinson (2022), linked in this archive's metadata. This archive contains models for the following pits:<br> Lacus Mortis Pit (LMP)<br> Mare Ingenii Pit (MIP)<br> Mare Tranquillitatis Pit (MTP)<br> Marius Hills Pit (MHP)<br> Schlüter Crater Pit (SCP)<br> Southwest Mare Fecunditatis Pit (SWFP)本存档包含点云数据，用于呈现月球上6处月坑的内部几何形态。这些点云通过对“倾斜立体像对”进行人工特征匹配生成：该像对由月球勘测轨道飞行器窄角相机（LROC NAC）拍摄的两幅不同离天底角度的影像组成，用于在相似光照条件下观测月坑的一侧坑壁。这些影像的像素分辨率约为0.3~2.2米/像素，据此可生成点间距约5~10米的点云数据，点间距具体取决于坑壁上可识别特征的密度。将多组立体像对生成的人工点云进行合并，并在可行时，将其与由更接近天底视角的NAC立体影像生成的密集数字地形模型（DTMs）进行配准与合并，最终得到可覆盖月坑上部坑壁、坑底及周边紧邻区域的点云数据。如需了解处理方法的完整细节，请查阅本存档元数据中附带的Wagner与Robinson（2022）相关文献。本存档包含以下月坑的相关模型： 死亡湖月坑（LMP） 智慧海月坑（MIP） 宁静海月坑（MTP） 马里乌斯丘陵月坑（MHP） 施吕特尔坑月坑（SCP） 丰饶海西南月坑（SWFP）
