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)

Digitizing Reality: Automated 3D Point Cloud Data Processing Using AI

Intelligent Point Clouds
Instruments for digitizing the 3D real environment are becoming smaller, more lightweight, lower-cost and more robust. Accordingly, they are finding increasingly widespread usage, not only on surveying tripods for the highest accuracy, but also on mobile platforms such as autonomous vehicles, drones, helicopters, aircraft, robotic vacuum cleaners, trains, mobile phones, satellites and Martian rovers. Lidar uses laser scanning, while photogrammetry records images from one or more cameras which may be moving. Each laser scan records tens of millions of data point positions and colours in a point cloud, and hundreds of such point clouds may be combined. This article discusses... (read more)

What Cloud Computing Means for Lidar in Construction

The construction sector is undergoing radical change. The industry is facing many challenges such as rising costs, tight project delivery and building sustainability. Above all, it must address the quality of construction and the need to constantly improve its processes. For a long time, the public clouds did not have what Lidar point cloud applications needed: high bandwidth networking, but this has been changing rapidly over the past couple of years. Digitalization will be crucial to making progress on these fronts, with 3D surveying and point cloud technology leading the charge. 2020 will mark a turning point in terms of... (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...
