Mobile Laser Scanning with 1cm Accuracy

Mobile mapping system StreetMapper has achieved accuracies of better than 1cm on a Californian test area specifically designed to evaluate mobile laser scanning systems. Operated by Terrametix and designed by Nottingham-based 3D Laser Mapping, the StreetMapper system was put through its paces on a stretch of highway in San Diego. The route was chosen by the Californian Department of Transportation (Caltrans) to help companies advance mobile laser scanning technology through independent evaluation against known control points.   The Caltrans test area covers a half-mile stretch of High Occupancy Vehicle (HOV) lane highway in San Diego. The route was originally selected... (read more)

Mobile Handheld Competes with Terrestrial Laser Scanning

The ZEB1 mobile handheld laser mapping system has been proven to be able to outperform traditional terrestrial laser scanning during field tests in Chile. Supplied by 3D Laser Mapping and operated by Chilean company GEOCOM, the ZEB1 was used to conduct a survey of a stockpile in a covered mining facility. The same area was scanned using a terrestrial laser scanner and the results were compared. Data capture with the ZEB1 was found to be around 5 times faster while automatic data processing, via 3D Laser Mapping’s secure server facility, took less than 5 minutes. Data accuracies and definitions were... (read more)

Point Clouds: Laser Scanning versus UAS Photogrammetry

Accuracy, Point Density, Time Efficiency and Costs
Are photogrammetric point clouds superior to Lidar point clouds, or is it the other way around? To address this topic of ongoing debate, the authors of this article conducted a terrestrial laser scanning (TLS) survey together with an unmanned aerial system (UAS) photogrammetric survey of a gravel pit. Comparison revealed that TLS is superior when the highest level of detail is required. For larger surveying projects, however, RTK-enabled UAS photogrammetry provides sufficient levels of detail and accuracy as well as greater efficiency and improved surveyor safety. In modern surveying, the numerous measurement methods can be divided into two broad categories:... (read more)

Photogrammetry and Laser Scanning on Single Aircraft

Diamond Aircraft, Austria, has introduced the new DA42 GEOSTAR that enables the collection of laser scanning and photo-grammetry data during one single flight. The team of Diamond Airborne Sensing (subsidiary of Diamond Aircraft) announced it has succeeded in perfect sensor integration on the DA42 MPP, the most economic remote sensing platform worldwide. Both systems are integrated with sufficient resources for fuel and flight crew. Hence the GEOSTAR is able to complete incredible 10-hour survey flights with a range of up to 1,042 NM, equivalent to the flight route Copenhagen - Barcelona. At an altitude of 10,000 feet it can even... (read more)

Catching up on Photogrammetry and Laser Scanning

An Impression of the Oldenburger 3D-Tage Event
In the German geospatial industry, there is a longstanding platform for open and constructive dialogue with researchers but also informal talks and discussion in between. It is called the Oldenburger 3D-Tage and is held annually at the Jade University of Applied Sciences in the northern German city of Oldenburg. This article provides a round-up of the 18th edition of the event which took place in February this year and offered delegates an inspiring update on the latest developments in all aspects of 3D mapping, both photogrammetry and laser scanning. The 3D-Tage programme is pretty straightforward: two full days of sessions... (read more)

Laser Scanning of Damaged Historical Icons

Surveying Technology Is Heading for Maturity
Terrestrial laser scanning is becoming an increasingly preferred surveying technique for the 3D documentation of historical buildings. 3D point clouds provide a wealth of information which advanced 3D mapping software can exploit in a relatively simple way, at least when compared to the tedious surveying techniques of the past. However, effective cooperation between architects and the survey team of experts is necessary in order to get the best out of this geodata acquisition technology. In this article, the authors first provide an overview of equipment based on the size of the site and the surveying aim, and subsequently give four... (read more)

Phase-based 3D Mobile Laser Scanning System

MDL’s Dynascan HD100 is a complete GNSS/INS mobile scanning system and comes complete with all operating accessories, computer and software. It utilises an ‘off the shelf’ FARO Focus3D phase-based scanner, making a Dynascan HD100 pod all that is needed to adapt the Focus3D unit (in minutes) to perform mobile scanning tasks at speeds up to 70 mph (102 kph) with a 300° field of view. Existing FARO customers already appreciate the price/performance advantages of the Terrestrial (Tripod Mounted) Focus3D scanners with a maximum vertical scan speed of 97 hz and +/- 2 mm accuracy at up to one million points...
