Point clouds of Constructie bridge on Westlandseweg, Delft, The Netherlands

Point clouds of Constructie bridge on Westlandseweg in Delft was acquired for the project “Laser Scanning for Automatic Bridge Assessment” or called “BridgeScan” funded through H2020 Marie Curie IF and for a big assignment of a course “3D Surveying of Civil and Offshore Infrastructure” of a Master program at TU Delft Dept. Geoscience and Remote sensing”. The Constructie bridge is a concrete bridge with mix-vehicle and tram bridge with one span over a channel. The data points of the bridge were acquired using Leica ScanStation P40, from 9 stations (5 below, 2 on a top and 1 each side) with the sampling step 6.3mm at the measure range of 10.0m. The point clouds from different scanning stations were registered using the artificial targets through Leica Cylone software. The point cloud of the bridge was used to reconstruct a 3D model and identify surface damage. The data set was down-sampled with the sampling step of 5mm.

代尔夫特市Westlandseweg大道上的康斯特鲁克西耶桥（Constructie bridge）点云（point clouds）数据集，其采集工作服务于两个项目：一是由欧盟地平线2020（H2020）玛丽·居里个人奖学金（Marie Curie IF）资助的"激光扫描自动桥梁评估"（Laser Scanning for Automatic Bridge Assessment，又称"BridgeScan"）项目；二是代尔夫特理工大学（TU Delft）地球科学与遥感系（Dept. Geoscience and Remote Sensing）开设的土木工程与近海基础设施三维测量硕士课程的大型课程作业。该康斯特鲁克西耶桥为混凝土结构桥梁，可同时通行机动车与有轨电车，单跨跨越一条航道。本次桥梁点云数据采用徕卡ScanStation P40扫描仪采集，共布设9个测站（下方5个、顶部2个、两侧各1个），在10.0米的测量范围内采样步距为6.3毫米。不同测站采集的点云通过徕卡Cylone软件依托人工靶标完成配准。该桥梁点云被用于重建三维模型并识别桥面表面损伤。本数据集已按照5毫米的采样步距完成下采样处理。
