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)

Gexcel Launches Solution for Multi-source 3D Data Processing

Gexcel, an Italian developer and producer of point cloud processing software, indoor mapping systems and Lidar monitoring solutions (OPMMS), has announced the new Reconstructor 4.0 release. This expands the opportunities to integrate 3D data collected with tripod, mobile, handheld scanners and UAVs, including imagery datasets. The new software version allows the users to work more efficiently with multi-source and multi-scale 3D data, especially in BIM, mining and geospatial applications where 3D and 2D sensors often have to be integrated to cover large areas with different resolutions. Among several new and updated tools and using a completely new rendering engine to... (read more)

Intergeo 2019: A Mind-boggling Amount of Data

It is generated in huge volumes and grows by the hour – data, data and more data. It stems from sensors, apps, IoT-linked devices, plants and satellites. According to the 'DataAge 2025' study, the data volume generated worldwide is set to rise from its current level of 33 zettabytes to around 175 zettabytes by 2025. Gathering, processing and visualizing data is particularly important in the geospatial industry. There has never been such a wide range of tools for this task as there is now. The possibilities have increased enormously, and the sky is full of point clouds. Now in its 25th year,... (read more)

NavVis Introduces Cloud-based Platform for Immersive 3D Buildings

NavVis, a German provider of indoor spatial intelligence solutions for enterprises, has announced the launch of NavVis Cloud. This new cloud-based platform gives laser scanning professionals access to NavVis IndoorViewer as a Software-as-a-Service (SaaS) solution. Fully immersive, web-based 3D buildings can now be delivered as part of every scan project using point cloud files from terrestrial laser scanners and the NavVis M6 indoor mobile mapping system (IMMS). NavVis IndoorViewer is a web-based application that transforms data captured by laser scanners into fully immersive 3D buildings. With a few clicks, scan data is automatically structured into a basic model of the... (read more)

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...

The Rising Demand for Total Stations and Terrestrial Laser Scanners

How the Booming Construction Business Boosts the Geospatial Industry
Increasing investments in large infrastructure and construction projects, and the rising role of building information modelling (BIM), are expected to drive the market for geospatial equipment. BIM’s close connection with spatial information makes it a familiar landscape and offers rich possibilities for surveyors and other geospatial professionals. Geomares – publisher of 'GIM International' and 'Geo-matching' – has analysed the user data and behaviour of thousands of members of the global geospatial community. It is interesting to see how the market of ‘traditional survey equipment’ such as total stations and terrestrial laser scanners is responding to the growing construction market and... (read more)

Digital Twins Drive Geospatial Market Growth

Unveiling the Findings from the Annual Industry Survey
The ever-increasing use of digital twins in infrastructure and construction projects is creating a huge need for 3D geodata, which in turn is driving strong growth in our industry. That is just one conclusion we can draw from the most recent ‘GIM International’ annual industry survey. As the geomatics landscape continues to evolve and diversify, many providers of mapping and surveying solutions are focusing on specific vertical markets, ranging from agriculture, forestry and archaeology to construction, mining and civil engineering. Read on for our analysis of the survey results, in which we identify key growth opportunities and highlight which new... (read more)

Bringing BIM Down to Earth

‘BIM’ is a hot topic in the industry, receiving regular coverage at many conferences, seminars and webinars. A lot of companies predict that it is one of the ‘next big things’ for the future, and a not inconsiderable number of companies are already working with BIM today. And that’s a good thing! But it is perhaps wise to look past the hype and keep our feet firmly on the ground. Tomas Sandström from Adtollo brings some nuance into the BIM discussion in this column. BIM stands for ‘building information modelling’, or perhaps ‘building information management’. The best thing about BIM... (read more)

FIG Commissions and Their Work Plans 2019-2022

On 1 January 2019, ten new FIG Commission chairs started their term of office. A kick-off meeting was held from 9-10 January in Copenhagen to discuss their work plans. During November/December 2018 they had already worked on the technical programme for the FIG Working Week 2019 (22-26 April in Hanoi, Vietnam). The programme was also discussed and fine-tuned at a creative workshop.The work plans will be presented in detail in Hanoi, but their overall ideas can already be revealed here. Commission 1 (Professional Standards and Practice) will engage surveyors in all member associations with the importance of acting ethically around... (read more)
