3D laser scanning is one of the fastest and most accurate measurement methods, often used in parallel with photogrammetry. 3D laser scanning is most widely used in architecture, construction and surveying, as well as in cartography, architectural inventory, deformation measurements of engineering structures, environmental studies and archaeology.więcej Kontakt
BIMfaktoria, a company that offers laser scanning in Warsaw and the Mazowieckie Voivodeship, as well as throughout Poland, is implementing more and more services based on 3D laser scanning. This is a result not only of the advantages of 3D laser scanning, but also of the fact that this technology significantly improves the processing of information obtained by measurement.
The results of laser scanning are point clouds that can be transformed into orthophotos, CAD models or BIM models, and the resulting mesh grids can be used to create virtual reality or visualization.
3D laser scanning is performed using ground-based or mobile SLAM laser scanners, as well as drones. The laser scanner emits a focused beam of light and, by reflecting it off building surfaces such as walls, ceilings, floors and fixtures, reads millions of measurement points.
The result is a three-dimensional coordinate system in the form of point clouds, and on its basis it is possible to create accurate 3D models with data such as:
There are four basic types of laser scanning:
The wide possibilities of 3D scanning make it eagerly used in various fields.
The most important examples of BIMfactoria’s use of 3D scanners are:
Point cloud processing software is able to perform control verification of data, and also assists in generating very detailed models of objects, and creating CAD documentation (necessary, for example, for architectural and construction inventories), It is helpful in collecting a complete database for conservation projects.
Laser scanners are increasingly used in inventories of industrial buildings, equipped with a number of installation systems, and in other places and objects that are too complicated for measurements by classical methods. We are talking about historic buildings, complex cubic projects or mines or tunnels that are subject to degradation or have been affected in some way by time.
Inventory work carried out by traditional methods requires a lot of manual measurements and the ordering and proper presentation of the results. Especially in the case of large objects, this consumes a lot of time and involves a considerable risk of mistakes. The situation is different with 3D laser scanning. The use of this technology from the point of view of the investor and the contractor is associated with many advantages.
The most important of these are:
