Lidar Point Cloud Segmentation

A Novel Framework for Processing Terrestrial Lidar Data
Terrestrial Lidar data has great potential to produce measurements for as-built building information modelling (BIM). Unfortunately, processing hundreds of millions of points, often contaminated by substantial noise, can be tedious and time-consuming. Normal variation analysis (Norvana) segmentation is an automatic method that can segment large terrestrial Lidar point clouds containing hundreds of millions of points within minutes. Thanks to the high speed, point density and accuracy of modern terrestrial laser scanning (TLS), as-built BIM can be conducted with a high level of detail. But TLS captures not only useful geometric information but also unwanted objects, such as people, animals or... (read more)

InfiPoints 6.0: Modelling Directly from Laser Scans to Autodesk Revit

Elysium has developed an advanced functionality to model piping and structures from 3D laser scanned point clouds into Autodesk Revit. This new capability is included in Elysium’s point cloud utilization software, InfiPoints 6.0, which has been release on 30 September. The new feature allows Revit users to reduce their modelling time significantly. There is no need any more to create models of existing facilities from scratch. Furthermore, the CAD data extracted from point cloud data in InfiPoints is automatically imported into Revit to add finishing touches. Lidar technology Industry pioneers and some service providers have recently begun employing 3D laser... (read more)

ISG Transforms 3D Model Delivery to Boost BIM Capabilities

Global construction services company ISG is using the latest 3D modelling technology to stimulate its building information modelling (BIM) capabilities. By introducing Pointfuse laser scanning software, ISG has speeded up workflows with rapid scan-to-BIM modelling whilst maintaining high levels of accuracy. Traditionally this laser data processing could take up to three days to 3D model a single floor. However, using Pointfuse, ISG has reduced this to a matter of hours. The use of Pointfuse has also increased the range of the point cloud outputs with applications including clash detection and visualization. “Scan-to-BIM modelling was previously seen as undesirable by the...
