Dataset for comparison of spatial data acquisition techniques for the geometric analysis of lunar regolith

This dataset contains 3D mesh models of lunar regolith simulant cones (Chenobi, LHS-1, LMS-1, LSP-2) and reference CEN sand, measured using a handheld laser scanner, photogrammetry, and a low-cost LiDAR sensor. The data include raw registered scans and cleaned cone meshes. They enable comparison of accuracy, resolution, and geometry reconstruction across methods, supporting future research in 3D measurement validation and soil analysis.

本数据集收录了采用手持激光扫描仪、摄影测量法及低成本激光雷达（LiDAR）传感器采集的模拟月壤锥形体（Chenobi、LHS-1、LMS-1、LSP-2）与参考CEN砂的三维网格模型，同时包含配准后的原始扫描数据与经清理优化的锥形体网格模型。本数据集可用于对比不同采集方法的精度、分辨率与几何重建效果，可为后续三维测量验证及土壤分析相关研究提供支撑。
