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. This article describes normal variation analysis (Norvana) segmentation – 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... (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...

3D Modelling for Construction

This article introduces topics on the state of the art comparing photogrammetry and Lidar for 3D modelling for construction. The advantages and disadvantages of both will be highlighted in terms of accuracy, complexity and cost. Breaking away from laser measurement in construction is a taboo subject perhaps hampering the use of photogrammetry. In construction aerial survey has enormous time saving benefits for measuring groundwork areas. Data can be used for asset classification, construction validation as well as health and safety. In particular regular scans provide a time series of work in progress to detect new issues, managing risk rather than... (read more)

Home Renovation Made Easy with Handheld 3D Scanning

As residential real estate prices continue to climb in many parts of the United States, property owners are increasingly investing in renovations and additions to their existing homes. To meet the demand, architects seek digital as-built documentation of the structures, so they can design the new construction. Many are asking for mobile 3D scanning by name as the technology they prefer to quickly capture the accurate, comprehensive as-built detail needed to start the design work. Business is booming for Precision Property Measurements (PPM), a Long Beach, California, firm that has provided as-built documentation services to Architecture, Engineering and Construction (AEC)...
