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)

3D Terrestrial Laser Scanner Investment

Plowman Craven has extended its 3D laser scanning capability with the new HDS7000 terrestrial laser scanning system from Leica Geosystems. The company has now procured one of the UK's first Leica HDS7000 ultra-high speed scanners to ensure the best combination of speed and accuracy for its measurement survey solutions.   With scanning speeds of up to one million points per second and an extended range of over 100 metres, the HDS7000 is claimed to have the best combination of high efficiency, accuracy and low scan noise at longer ranges.   David Norris, Technical Director at Plowman Craven says, "The addition...

Improving Geomechanical Analysis with Terrestrial Laser Scanners

Solid as a Rock?
People often describe something hard and immovable as ‘solid as a rock’. But rock does not always live up to its reputation. Depending on its characteristics and local conditions, sections of rock may slip, slide, crumble or deform, with potentially serious consequences. Geologists study the geomechanical properties of rock masses to understand how they may fail. This is traditionally done by measuring the characteristics of the rock mass discontinuity sets by climbing the rock face or by using photogrammetry, but terrestrial laser scanning (TLS) has caught the attention of geologists as being a safer and more effective method.

Laser Scanning in Deformation Measurements

Acquiring 3D Spatial Data of Bridges
State-of-the-art geodetic and remote sensing techniques can prove their potential through particular engineering applications. Here we discuss load test measurements of bridges over the Danube. Prior to the particular bridge surveying projects, accuracy analysis was carried out in the laboratory. We describe the shortcomings and limitations of remote sensing and propose the joint application of traditional and remote sensing technologies. We also provide recommendations for further applications of laser scanning in deformation measurement of structures. View Larger Map Terrestrial laser scanning is a state-of-the-art remote sensing technology that can rapidly acquire accurate three-dimensional (3D) spatial data. The primary engineering applications... (read more)

Mine Tour for Terrestrial Laser Scanner

The RIEGL VZ-4000 laser scanner is capable of up to 222,000 measurements per second at a maximum range of 4,000 metres. In April 2012, the VZ-4000 toured the world to prove it, with demonstrations taking place in mines in both Chile and Russia. On Monday, 2 April 2012, Thomas Gaisecker, senior manager International Sales and RIEGL mining expert, arrived in Santiago, Chile to start a demo tour organised by RIEGL distribution partner Geocom S.A. The next day, demo scans at Minera Los Pelambres (image), were scheduled. Most of Chile’s mines are situated at between 3,000 and 4,000m above sea level, where... (read more)

Laser Scanning on the Go

How Wearable Reality Capture is Shaping the Industry
As the world's population keeps growing and changes in buildings and infrastructures become more rapid, there is an increasing need to document this growth and these changes. A revolutionary approach to geospatial documentation on a local, individual scale can help to meet this need. New systems enable users to walk around unhindered while logging reliable data about time, position and the world in 3D. Referred to as ‘wearable reality capture systems’, this new concept is shaping how measurement professionals come to understand the world around them. Read this article to find out more about the impact of wearable reality capture on the industry... (read more)

Mobile Laser Scanning Point Clouds

Status and Prospects of Automatic 3D Mapping of Road Objects
The demand for 3D maps of cities and road networks is steadily increasing and mobile mapping systems are often the preferred geodata acquisition method for capturing such scenes. Manual processing of point clouds is labour-intensive and thus time-consuming and expensive. This article focuses on the state of the art of automatic classification and 3D mapping of road objects from point clouds acquired by mobile mapping systems and considers the feasibility of exploiting scene knowledge to increase the robustness of classification. Management of roads, their maintenance or reconstruction,  requires inventories on pavement conditions, road markings and objects in the vicinity of... (read more)

Laser Scanning to Track Dinosaurs

3D Laser Mapping (United Kingdom) has supplied a high performance laser scanning system to assist with a European research project to map the footprints of dinosaurs. The project, jointly undertaken by the University of Manchester and Universitat Autònoma de Barcelona, used a Riegl laser scanner with integrated digital camera and satellite positioning technology to accurately record and locate individual dinosaur footprints. The project is tracing the movements of dinosaurs and is assessing the effects of weathering and erosion on the footprints.  “This project would simply not have been possible without the laser scanning system,” said Dr David Hodgetts, Lecturer in Reservoir...

Mobile Laser Scanning in Venice

Grand Canal in Scan- and Image Data
High measurement rates and centimetre precision point-clouds are state-of-the-art in mobile laser scanning. The introduction of photogram­metric features as next logical step considerably expanded the horizon of potential applications. Digital 3D documentation of Venetian cultural heritage as represented by the Grand Canal has until recently been achieved only for a few individual buildings. Now, in a collaborative project carried out by Universitá IUAV di Venezia and mobile-scanning system VMX-250 manufacturer RIEGL Laser Measurement Systems, the entire Grand Canal area has been registered in time-stamped image and scan data, complete with precise location and position data. The IUAV CIRCE Photogrammetry Lab... (read more)

Innovative Archaeological Laser Scanning Project

Laser scanning technology has been used to create a permanent and lasting record of post-mediaeval underground mines under the city of Bath, UK. The project by Oxford Archaeology employed laser scanning specialists APR Services to capture accurate measurements of the abandoned limestone workings at Combe Down. The laser-scanned measurements were used to create a permanent record of the internationally recognised heritage, wildlife and environmental site and inform stabilisation works to remove the very real threat to life and property posed by the unstable mine. Ianto Wain, head of Heritage Management at Oxford Archaeology, explained that laser scanning was the only... (read more)
