Intensity dataset acquired through laser scanning of lunar and Martian soil simulants

The data were acquired using two different types of terrestrial laser scanners. The first was a time-of-flight scanner Leica ScanStation C−10, the second was a phase-shift scanner Z + F IMAGER 5016. The research programme covered scanning soil specimens from different distances (15 m, 30 m, 60 m, 90 m, 120 m, 150 m, 200 m). Lunar Soil Simulant (LSS), Martian Soil Simulant (MSS) and Earth Soil Simulant (ESS) were used to prepare target specimens for scanning. The target specimens were oriented approximately perpendicular to the laser beam. The incidence angle was ranging between 0 and 1.5degree. Data format: Raw - Point cloud (*.pts format) X, Y, Z, Intensity (-2048 – +2048); for Leica ScanStation C−10 X, Y, Z, Intensity (0 – 1); for Z + F IMAGER 5016

本数据集通过两台不同型号的地面激光扫描仪（terrestrial laser scanner）采集获取。第一台为飞行时间扫描仪（time-of-flight scanner）Leica ScanStation C−10，第二台为相移扫描仪（phase-shift scanner）Z + F IMAGER 5016。本次研究覆盖了不同扫描距离下的土壤样本扫描任务，扫描距离分别为15 m、30 m、60 m、90 m、120 m、150 m及200 m。实验选用月壤模拟物（Lunar Soil Simulant, LSS）、火星土壤模拟物（Martian Soil Simulant, MSS）与地球土壤模拟物（Earth Soil Simulant, ESS）制备扫描用目标样本。目标样本与激光光束大致保持垂直取向，入射角范围介于0°至1.5°之间。数据格式说明如下：原始点云数据采用*.pts格式存储，通用字段包含X、Y、Z坐标与强度值（取值范围为-2048 至 +2048）；其中Leica ScanStation C−10采集的数据的强度值范围为0 至 1；Z + F IMAGER 5016采集的数据字段包含X、Y、Z坐标及强度值。
