高精度点云数据集

该数据集面向数字化缺陷检测与高精度验证需求，涵盖了实测与仿真两类关键点云资源，其中实测点云在恒温恒湿洁净实验室环境下，利用基恩士等微米级高精度激光扫描设备对工业产品标准件采集而成，真实捕捉了部件表面的微观几何特征；模拟点云则通过CloudCompare、PCL及Open3D等专业软件进行参数化建模，可精准调控点云密度、噪声水平及缺陷形态。数据集包含10个典型样本（实测与仿真各5个），采用PCD等通用标准格式存储。本数据集可用于数字孪生建模软件在曲面重建、特征提取、缺陷识别等方面的精度验证，并为实现5微米建模精度的达标验证提供数据支撑。This dataset is tailored for the demands of digital defect detection and high-precision validation. It includes two types of core point cloud resources: measured and simulated point clouds. The measured point clouds are collected from standard industrial components using micron-level high-precision laser scanning devices such as Keyence in a constant-temperature, constant-humidity and clean laboratory environment, which accurately capture the micro-geometric features on component surfaces. The simulated point clouds are generated via parametric modeling with professional software including CloudCompare, PCL and Open3D, enabling precise adjustment of point cloud density, noise level and defect morphology. The dataset contains 10 typical samples (5 measured and 5 simulated ones), stored in common standard formats such as PCD. This dataset can be used for precision validation of digital twin modeling software in tasks like surface reconstruction, feature extraction and defect recognition, and provides data support for compliance validation targeting 5-micron modeling accuracy.
