Mobile Laser Scanning System for French Railway Mapping Project

SNCF, the national French railway society, has taken delivery of a RIEGL VMX-450-RAIL intended for the sole purpose of railway mapping. The complete scanning platform can be either installed onto a mounting rack at the rear of a wagon or right into the engine cart. The main tasks of railway mapping include georeferencing railway infrastructure, clearance monitoring in order to detect natural obstacles like vegetation, or determining infrastructural limits for special-load transportation. Other applications of railway scanning include track and base terrain inspection, as well as supervision and registration of changes in train station structures, such as thresholds between platforms...

3D Modelling of a Gold Mine Using Laser Scanning

The Digital Mine
A gold mine in China’s Shandong Province is the country’s first underground mine to use 3D laser scanning. During a one-year project, 20km of major tunnels were scanned and the point clouds processed. The resulting ‘digital mine’ enables better planning and designing, checking of production quantities and monitoring of tunnelling and mining machines, as well as improved safety. The authors describe how laser scanning has been used for 3D modelling of a gold mine. China’s key gold deposits are located in Shandong Province, where the region’s largest producing mine is operated by the Shandong Gold Group (SGG), a state-owned enterprise... (read more)

Adapting 3D Laser Scanning for the Surveyor

Meeting Specific Needs to Increase Productivity
3D laser scanning is a powerful measurement technology for obtaining 3D coordinates of object points at a speed of up to 5,000 points per second. But surveyors see lack of scanner versatility and unfamiliar workflow as limiting factors. Today, increased portability and robustness and adapted workflow enable surveyors to easily incorporate 3D scanning into their portfolio. A short learning curve allows for increased productivity and creates new business opportunities. Today 3D laser scanning is based either on phase-shift or on time-of-flight measurement. Phase-shift technology works by sending a laser beam with a sinusoidal wave to the centre of a rotating... (read more)

Engineering to ‘Bridge the Gap’ on Laser Scanning

It is no secret that where large-scale major investment is concerned in the current economic climate, infrastructure is a serious front-runner. As one component of a multi-pronged assault on rectifying the UK’s extensive debt crisis, the British government has pledged billions of pounds to the preservation and vast improvement of the country’s arterial infrastructure systems in the hope of kick-starting the country’s long-term economic growth. With high-profile projects such as HS2 and Crossrail at the vanguard of the GBP36billion major infrastructure investment plan, the subject of national infrastructure was one of 2014’s hot topics.  Opti-cal, a supplier of land survey and...

Indoor Mapping with Terrestrial Photogrammetry

Swiss engineering and geomatics consulting firm Mosini Caviezel SA has been testing terrestrial photogrammetry for indoor mapping as a new method for establishing property plans. The company is evaluating the optimal indoor mapping workflow and testing different positions and methods for data capture. The project consisted of several phases and took place in an office building of Mosini Caviezel SA, Switzerland: a rural house that includes five rooms and a large hallway. The main objectives were to create an indoor plan in 2D, evaluate the application of terrestrial photogrammetry for establishing a PPE (Propriété Par Étages/property by floors, or condominium...

Time-space Modelling with Terrestrial Lidar

Monitoring Ice Cliff Evolution of the Miage Glacier, Italy, with ILRIS-3D
The Miage Glacier at Mont Blanc Massif, with an area totalling 11km2, is the third largest glacier in Italy. Time-space modelling of the lakebed and glacier walls carried out with terrestrial Lidar revealed that the ice cliff had retreated more than 45m between July 2003 and September 2004. The Miage Lake area, which has been a tourist attraction and object of study for decades, has been affected by at least seventeen drainage events over the past hundred years, the most recent just last year. Observations during this last event suggest that an increased discharge of water from the lake, resulting... (read more)
