Long-range Terrestrial Laser Scanner

The RIEGL VZ-1000 high-performance Terrestrial Laser Scanner for long range applications is launched at INTERGEO 2010 in Cologne. The scanner is especially qualified for surveying in open pit mining. The RIEGL VZ-1000 offers a very long range up to 1400m, in combination with high-accuracy and high-precision, while still operating in Laser Class 1.   Obviously, considering its operational area, the instrument is dust and splash-proof. Laser technology offers multiple target detection for each single laser shot, and consequently allows achieving superior measurement capability even under adverse atmospheric conditions and excellent penetration of vegetation.   (read more)

Continuous Mobile Laser Scanning

Mobile Platform Terrestrial Lidar, IMU and GPS
Combining Terrestrial Laser Scanning, Position and Orientation Systems and GPS receivers into a mobile mapping system enables effective mapping of large and complex terrain. The authors tested a mobile mapping system at two sites: in an open pit mine, and along a road.<P> Optech and Sineco have been developing a mobile mapping system, initially based on a platform combining the ILRIS-3D (Intelligent Laser Ranging and Imaging System), the Applanix POS LV (land-based vehicle) and GPS receivers. This new system, ILRIS-MC (Motion Compensation), can be installed on any mobile platform and performs fast surveys, generating point-clouds in real time in WGS84... (read more)

Mobile Laser Scanning Platform

RIEGL Laser Measurement Systems' V-Line laser scanner generation was a main feature in the overview of the company's laser scanner product range at Intergeo. The Austrian company was showing terrestrial, airborne, mobile and industrial applications.   The combination of the last year launched V-Line Laser Scanners with appropriate IMU/GPS equipment results in this year's RIEGL innovation: the Mobile Laser Scanning System RIEGL VMX-250.   This compact, rugged and lightweight mobile laser scanning system for highly accurate and high-resolution dynamic 3D data collection impresses with its extraordinary ease of use which convinced the visitors during the live presentation. The system consists... (read more)

Laser Scanning and Archaeology

Standard Tool for 3D Documentation of Excavations
Terrestrial 3D laser scanning will become the future standard tool for high-resolution 3D documentation of archaeological excavations, but its capabilities are still underestimated by professional archaeologists and providers of scanners or scanning services. The new tool forces archaeologists to consider extension of archaeological stratigraphy theory. The author shows examples of the beneficial use of laser scanning and proposes an extended theory. Excavation forms the main data retrieval process in field archae­ology but is also destructive, based as is it upon salvaging in the reverse order of deposition or creation. Reconstruction of the site as it was is very important and... (read more)

Laser-scanning and Heritage

Academic and Manufacturer Face Challenges
The March issue of GIM International carried the response of manufacturers of laser-scanning sensors and software to remarks made in the Insider’s View column on shortcomings of this technology in the spatial documentation of heritage sites. Based on his long-term experience in capturing heritage sites in Africa, Professor Rüther explains there is still ample room for development, a challenge for both academic and manufacturer. Judging from the responses to my original column, it appears some manufacturers interpreted my observations as rejection of laser scanning as a tool for heritage documentation. The opposite is true. Without doubt, laser scanning has high... (read more)

Laser Scanning Technology Challenged

Shortcomings in Spatial Documentation of Heritage Sites
In this month’s Insider’s View Prof. Heinz Rüther puts some critical points on the shortcomings of laser-scanning technology in the spatial documentation of heritage sites. We invited manufacturers of laser-scanning sensors and software to comment on his challenging observations. Nearly 70% of the companies responded (ten in total) and seven felt qualified to reply: Optech, Riegl, Leica Geosystems, 3rd Tech, Visual Learning Systems, TopoSys and I-SiTE 3D Laser Imaging. We thank all respondents for their time and effort. Critical observations made by Prof. Heinz Rüther include the following. (1) The processing time of laser-scan data can be up to ten... (read more)

Portable Laser Scanning System

3D Laser Mapping (UK) has developed a portable laser scanning system for mapping overhead infrastructure such as power lines. With adverse weather and over-grown vegetation increasingly causing damage to overhead cables, the system can be carried as a backpack to instantly map the position of cables and the proximity of nearby vegetation. 3D Laser Mapping developed the portable system following major power outages in Europe. Using mobile laser technology, the system links to specially developed software that automatically identifies areas of risk so that utilities can prioritise their maintenance activities. The system is highly portable; mounted on an off road... (read more)

Laser Scanning Software

Z+F UK develop their own brand of laser scanning software called 'Light Form Modeller' or LFM. LFM is known for its array of CAD interfaces that allow users to seamlessly integrate laser scan data into their preferred CAD or review package.     LFM is part of the Bentley and Autodesk developer Networks. It can interface with Microstation, AutoPlant, AutoCAD, CADWorx and also VR Context's Walkinside product. It is also above to interface with CAD packages for the Process market e.g. Intergraphs PDS, SmartPlant Review, SmartPlant 3D and AVEVA's PDMS and Review packages. In relation to colour laser scan data... (read more)

Laser Scanning Data Processor

The latest version of Pointools Edit utilises the full power of 64-bit for faster editing and processing of point cloud data, the millions of 3D measurements collected by laser scanning devices. The application builds on the features of View Pro visualisation software, with point cloud layer-based editing and segmentation. Pointools Edit also enables simple RGB re-colouring together with easy noise and obstruction cleaning. Pointools Edit features point layer technology for flexibility and speed when editing point cloud data. Layers can be used to segment, clean and re-colour the huge data files created by laser scanning instruments. Colour errors can also... (read more)
