Point cloud processing services is a process that targets on images modification captured with a 3D laser scanner. The laser scanner is a measuring instrument mounted on a tripod. It is used to survey existing buildings or at a new construction site. The device rotates 360 degrees around the axis, emits millions of laser beams per minute and catches their reflections. A surveyor moves the scanner through a job site and stops several times to make the measurements. These are called substations. No blind zones should be left. As a result, once the field operations are complete, the raw data – point cloud – is taken to the office. Here is where BIM Machine steps in the game.
Point cloud processing services and scans registration
– A scanner couldn’t stitch the raw point cloud data without errors itself
– Problems with the raw point cloud data:
- A scanner might not read correctly\completely the spheres or stamps used as reference points
- A surveyor might not use spheres or stamps. As well as vibration during the scanning process might cause scans corruption
- misconfiguration in the scanner setting (scanning distance, point cloud density, etc)
We merge individual scans into a solid 3d cloud model. Edit and align them manually if semi-automatic tools do not work as intended
As a deliverable, you get a clean file that is import-ready for a CAD software or for a BIM model
Point cloud data cleaning
– People, cars, atmospheric fallout, trees, reflections, dust, bad lighting conditions, other factors cause the background noise that always appears in point cloud scans
We cut off excessive data (far distance objects, unnecessary for scanning purposes objects, etc), clean and edit files with the help of specialized software like Autodesk Recap 360 PRO, Faro Scene, Leica Cyclone
As a deliverable, you get a clean file that could be taken to the CAD software or into a BIM model
Point cloud isolation
– An architect, MEP designer or a construction specialist might need to hide a part of the point cloud scan temporary. For example, a wall or a ceiling.
We split the scan into functional layers depending on customer requirements. Or, as an alternative, our specialists may break one big scan into a few smaller scans.
Specialized professionals like architects, MEP-designers, etc. can work with the minimum required amount of data.
