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)

Using Drones in Construction for Aerial Inspection, Photogrammetry or Lidar

Drones are creating new workflows, processes and applications in construction design, surveying and mapping, and many see them as the future of the construction industry. Rick Rayhel, Microdrones' sales manager for United States' Western Region, is one of those people; he's seen first hand how drones can enhance the construction business. In the U.S., drones have only been used to aid construction in the last couple of years. On the precipice of drone potential, Rayhel said, “There’s never a lack of ideas or interest on what can be done with drones.” Perhaps the biggest advantage of drones in construction, though,...

What's the Difference Between SLAM Algorithms for Handheld Lidar?

To get the full story when researching handheld Lidar scanners, you also need to compare the SLAM algorithms. These three criteria will help you: processing speed, sensor integration and colorization. While researching handheld Lidar scanners, you will probably scour spec sheets, cross-reference features, and read about software workflows. But that will get you only part of the way to understanding the market – you will also need to compare the simultaneous localization and mapping (SLAM) algorithms that power these devices and enable them to create a point cloud as you walk. The problem is that SLAM algorithms can be difficult... (read more)

Apple Unveils New iPad Pro with Lidar Scanner

Apple has announced its most advanced iPad Pro ever, which even includes a Lidar scanner. Equipped with the A12Z Bionic chip, the new iPad Pro is faster and more powerful than many PC laptops. The breakthrough Lidar scanner delivers depth-sensing capabilities, opening up more specialized workflows and supporting professional photo and video apps in combination with the ultrawide camera and studio-quality microphones. The Lidar scanner – along with pro cameras, motion sensors, pro performance, pro audio, a Liquid Retina display and powerful apps – lends weight to Apple's ambition to offer the world’s best device for augmented reality (AR). The... (read more)

What Cloud Computing Means for Lidar in Construction

Increased focus on cloud computing and point clouds in the construction sector is expected to result in new levels of speed, collaboration and real-time communication. 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... (read more)

3D Modelling for Construction

When it comes to 3D modelling for construction, what are the advantages and disadvantages of photogrammetry versus Lidar 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 and 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 responding to it. This article looks at the state of... (read more)
