Hardware-Software Partnership Introduces Real-time 3D Mobile Mapping and Construction Verification

At the recent SPAR 3D & AEC NEXT conferences in Anaheim, California, USA, ClearEdge3D, maker of EdgeWise, Verity and Rithm for Navisworks software, announced a collaboration with Gexcel, maker of HERON wearable scanners. The two companies have joined forces to make it quicker and easier for AEC professionals to conveniently gather as-built data with Gexcel’s HERON wearable laser scanners, and to compare that data against design/fabrication models using ClearEdge3D’s Verity software. This allows 100% verification of installed work in real time. "The partnership between ClearEdge3D and Gexcel brings together two globally recognized AEC tech leaders in the 3D world that...

New GeoSLAM Scanner Combines Detailed Data Points with High-resolution Imagery

Geospatial mapping technology specialist GeoSLAM has launched its latest product that offers property professionals the ability to capture floorplans and high-resolution photography simultaneously. The ZEB PANO, a handheld simultaneous localization and mapping (SLAM) scanner and panoramic camera, has been developed for the property sector. SLAM technology is widely known for its use in the automotive industry for self-driving cars, but the technology has applications far beyond that. Capable of capturing 43,000 data points per second and high-resolution panoramic imagery at the same time, the ZEB PANO stores the exact location of each panoramic image enabling quicker, more accurate, and less...

Technologies for the Future: A Lidar Overview

Building the Capability for High-density 3D Data
Point clouds can be captured by an ever-increasing number of means to understand the surrounding reality and detect critical developments. Diverse applications of 3D laser scanning or ‘Lidar’, which is a technology on a sky-rocketing path to be used for mapping and surveying, are changing the way we collect and refine topographic data. Which technologies and processes are building the capability for high-density 3D data? This article outlines the latest industry developments. National topographic databases store data refined from field measurements, imagery and laser scanning data at certain specifications and purposes, but lack the ability to adapt to ever-changing needs...

Recent Developments in Close-range Photogrammetry

A Measurement Technology in Transition
Dramatic advances in automatic digital image analysis have opened up new applications and made photogrammetry applicable for a broader field of users that lack specific knowledge of photogrammetry. Megatrends such as Industry 4.0, building information modelling (BIM) and the digital transformation are driving the advancement of 3D measurement technologies, both in terms of high-end systems and low-cost sensors. New technical challenges such as autonomous driving or unmanned aerial vehicles are demanding innovative sensor systems, but also extended maps and models of the environment. Modern approaches such as structure from motion (SfM), simultaneous localization and mapping (SLAM) or visual odometry are... (read more)

NavVis Deploys SLAM to Automatically Remove Point Cloud Artifacts

NavVis, the Germany-based global provider of indoor spatial intelligence solutions for enterprises, has released new software for the NavVis M6 indoor mobile mapping system (IMMS) that automatically detects and removes dynamic objects and object fringe points from point clouds during the post-processing of scan data. Fringe points and dynamic objects are two common types of point cloud artifacts that affect all 3D laser scanning devices. Fringe points arise when a laser beam hits the edge of an object as well as its background. This scattered beam ultimately appears as a so-called fringe around the edge of the object in the...

Looking ahead to the ISPRS Geospatial Week 2019 in the Netherlands

If you are looking for a good opportunity to take a deep dive into the latest geospatial technology and science, look no further. The ISPRS Geospatial Week 2019 will take place from 10-14 June in Enschede, the Netherlands, on the green campus of the University of Twente with Prof George Vosselman as Geospatial Week director. The five days will cover the latest advances, for instance, in using unmanned aerial vehicles (UAVs) in geomatics, in deploying the latest sensor technology such as hyperspectral sensing, and in the role of artificial intelligence in handling this sensory big data. Those worried about climate... (read more)

Point Clouds as the Future Topographic Core Data

Technologies and Means towards a Paradigm Shift
Could 3D point cloud data be used as the framework for topographic information in the future? Point clouds can be captured with an ever-increasing number of means from ground-based, airborne and spaceborne platforms to understand the surrounding reality and detect critical developments. What are the future technologies and processes that will build the capability for high-density 3D data? This article explores the possibilities based on the latest developments in the industry. ‘Data on demand’ is a recognized megatrend in the geospatial industry. National topographic databases store data refined from field measurements, imagery and laser scanning data at certain specifications and... (read more)

The Multispectral Journey of Lidar

Adding Channels to Laser Scanners Will Disrupt Lidar-based Target Identification
Optech Titan-3 has ushered in the era of multispectral airborne laser scanning, but multispectral terrestrial laser scanning (TLS) is still only available via research instruments, mostly for ecological vegetation studies. Analysing spectral ratios can reveal much about vegetation status and health, and multi-wavelength Lidar enables this analysis in 3D. However, multispectral Lidar will disrupt many other fields in the future. This article provides some first glimpses of how and why. Four research groups have published 3D TLS point clouds since 2012, and many others have already focused on the multispectral laser return rather than spatial analysis. Multi-wavelength point clouds are... (read more)
