The 3D laser scanners are measuring devices based on LiDAR technology. They include one or more LiDAR sensors that emit a light beam that scans the environment horizontally and vertically to capture it in 3D.
They make it possible to generate a point cloud (raw 3D data), but also image and thermal data depending on the models.
A traditional and widely used scanning solution, static scanners are tripod-mounted measuring devices.
Our static scanning solutions excel when it comes to complex areas... They complement our mobile scanning perfectly, offering high-precision capture for congested spaces, hard-to-reach zones, and long-range, high-density bridge clouds.
The best known static scanner manufacturers are Faro and Leica.
Mobile laser scanners are measuring devices that allow you to scan an environment while moving. Thus, they offer a very large survey volume, which can reach up to 12,000 m² per day.
The survey is therefore faster, without neglecting precision, which is why we put these scanning solutions at the center of our scanning protocol.
The choice of scanning solutions will be directly linked to the final exploitation of the data (plans, BIM/CAD models, etc.), to your specifications and to the specificities of your buildings.
Each project must be studied individually, to discover the advantages of possible digitization solutions, we invite you to read our item on this subject.
The point cloud of a building is a real 3D envelope of the building. Technically, it is generated using LiDAR sensors, which lasergrammetry solutions are equipped with.
These sensors emit a laser beam that scans the environment until obstacles (object, wall, structure, etc.) are detected. The distance to each obstacle is then analyzed, in order to position a point in space. Repeating this process makes it possible to create a point cloud.
During our projects, we deliver the file containing the point cloud in a format adapted to your uses (.rcp, .e57, .xyz).
To find out more, we invite you to discover our article explaining How to use a point cloud.
Scan to BIM corresponds to a process of modeling the existing environment for which the building's point cloud is used as a 3D footprint.
This methodology makes it possible to rely on an imprint of reality with centimetric precision for CAD/BIM modeling.
To find out more, we detail the different steps of a Scan-to-BIM method in this item.
We identify 5 key steps in the course of a digitization project:
