3D scanners incorporate LiDAR sensors, emitting a laser beam that scans their environment vertically and horizontally until obstacles are detected (object, wall, etc.).
The distance to each obstacle is then analyzed, in order to position a point in space, the repetition of this process makes it possible to constitute a point cloud.It is this point cloud that will be exploited as a 3D imprint of reality to create a digital model, a 2D plan, an elevation or a facade plane.
Several factors make it possible to choose the 3D scanning solutions most suited to your project. The first is that of the deliverables expected at the end of the project. Then, it will be a question of studying the specifics of the building (surface, height, space, etc.) to refine this choice and select one or more survey solutions.
This choice is decisive, we have identified it as one of key points for a successful 3D scanning project.
