What / how?
Preparation of the spatial point cloud model using a laser scanner survey.
When to use them?
In the case of an existing building or one under construction digital mapping of the current spatial layout, conditions or readiness is required for further use (e.g. planned conversion).
Point cloud modelling for large investments
Whether it’s to accurately draw up plans, assist in construction or to operate the completed building, 3D models of a building using point cloud modelling are a huge help to the construction industry. Point cloud technology can be used to create a realistic and accurate model of the building, which can be easily used in modern Building Information Modelling (BIM) frameworks.
What is a point cloud?
A point cloud is a data set that contains a number of data points, or focal points. Each point has its own X, Y and Z coordinates so that the resulting model can represent 3D shapes or structures. As can be observed for an image and its constituent pixels, the denser the point cloud, the more accurate and detailed the 3D model will be. Point cloud models are created using so-called LIDAR (Light Detection and Ranging) technology, using a laser scanner to measure an area or an existing structure against which the software displays the 3D model.
The benefits of point cloud modelling in the construction industry
- Efficiency: the point cloud model data can be easily managed and arranged in software, saving long hours of work for the various project stakeholders.
- Accuracy: the geolocation-accurate 3D models produced help to deliver accurate, detailed designs in unprecedented ways.
- Cost-effectiveness: working quickly and accurately also means that significant costs can be cut from both the design and construction process.
