3D Laser Scanning
Technical Explanation
3D Laser Scanning (High-Definition Surveying) uses a LiDAR scanner on a tripod or mobile platform to rapidly capture millions of points of surrounding surfaces. It produces a point cloud – a dense 3D dataset of buildings, plants, terrain, etc. – with high accuracy. This is used to create as-built 3D models, detect structural deformations, or document cultural heritage with millimeter detail.
Main requirements
Required for detailed 3D documentation of structures or sites (e.g. plant facilities, complex buildings, historical monuments). Needs clear line-of-sight to surfaces (often multiple scan setups to cover all angles). The main requirement is a stable setup and targets for registration so that scans can be merged into a single coordinate system.
