Virtual Worlds: Research Trends in Mobile 3D Data Collection

30.11.2016

Technological advances in mobile laser scanning have substantially increased the quality of 3D measurements in recent years and made possible new applications. Over one hundred mobile laser scanning experts gathered at Fraunhofer IPM’s international MoLaS Mobile Laser Scanning Technology Workshop to discuss the state of the art, applications and new products.

Mobile laser scanning has developed to become one of the most important technologies for the 3D mapping of objects. Installed on measurement cars or trains, on aircrafts or ships, laser scanners measure large areas without physical contact.

The measurement data can be used to create a highly detailed 3D image of the environment which may be almost photo-realistic depending on measuring conditions. Mobile laser scanners measure extremely fast, ever-more efficiently and precisely thanks to technological advances. Some units are now so small and lightweight that they can be used on drones.

In the spotlight: Indoor mapping and stand-alone applications

Nowadays, mobile laser scanners are already being used for applications way beyond classical land surveying, i.e. obtaining geodata: specialized surveying service providers rely on mobile laser scanners to measure and survey roads, rails, bridges, buildings or even agricultural areas. There is increasing interest in indoor navigation, i.e. measuring interiors. A 3D image of the interior airports, museums, factory shops or office buildings, which is generated at regular intervals, can be used in many ways, for example with a view to security aspects.

The automobile industry is testing laser scanners in the context of driverless cars. What role do laser scanners play in interaction with other sensors? What is the upper cost limit? How big may the the scanners be? How reliably do they operate throughout a car’s life cycle?

In the words of Dr. Matthias Buthenut of IAV GmbH, an automotive-engineering service provider operating worldwide, when presenting the expectations and requirements of the automobile industry in relation to the technology: »there are many unanswered questions in relation to mobile laser scanners, above all as regards the enormous amounts of data they generate and how this data can be fused with other sensors«.

Visualizing measurement data is becoming more important

Processing and visualizing measurement data are increasingly important processes in mobile laser scanning. How can required objects be extracted as efficiently as possible from large quantities of measurement data? How can the data be presented so that the user is provided as quickly and conveniently as possible with the required information?

Several speakers presented new visualization options. Dr. Jürgen Sturm of Google Germany explained strategies for 3D reconstruction of measurement data on the basis of the Google Tango technology platform. The aim of Tango is to teach mobile devices how to see and orientate themselves in 3D without the need for GPS data. Tango obtains the data using a depth-sensing camera but the challenges in relation to data processing and data interpretation are similar to those of laser scanning.

In the words of Dr. Alexander Reiterer of Fraunhofer IPM who set the event in motion: »the topic of laser scanning is a very dynamic one. This was shown once again clearly by the Workshop«. As he went on to say: »industry is showing major interest but it is also pointing up specific requirements on the technology, which does, of course, spur us scientists on. So swapping information and ideas between industry and research is more important than ever before«.

The MoLaS Technology Workshop is held every two years. The next Workshop will be held in November 2018

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
