01/16 Switzerland: Kantonspolizei Zurich is Using RIEGL's VP-1 for Airborne and Mobile Scanning

Kantonspolizei Zurich is successfully using their RIEGL VP-1 with integrated VUX-1 LiDAR sensor for airborne and mobile data acquisition.

In the air, the laser scanning system is used for extensive airborne forensic coverage. Now, the system is also being utilized as a mobile mapping system, proving the flexibility and versatility of RIEGL's VUX-1 sensor.

In 2012 Kantonspolizei Zurich already ordered two RIEGL VZ-400 to use this 3D Terrestrial Laser Scanners for forensic purposes. The RIEGL VZ-400 as a very compact and lightweight surveying instrument, mountable in any orientation and even under limited space conditions provides high-accuracy and also high speed data acquisition for a much faster investigation of  crime scenes.

Due to the fact that by the use of RIEGL VZ-400 it is possible to collect more data in less time Kantonspolizei Zurich made another step in this direction and purchased the RIEGL VP-1 by the end of 2015.

Concerning the article „Der Superscanner der Polizei ist gelandet“ published in the Tagesanzeiger, Switzerland, (www.tagesanzeiger.ch) on November 19, 2015, we had many requests from our partners and prospects concerning an English version. Therefore we have translated the German article for you:


RIEGL VP-1 sucessfully used by Kantonspolizei Zurich

Acquiring up to 500,000 measurements per second and originally designed for airborne use, the RIEGL VP-1 of KAPO Zurich is now used for mobile mapping applications.

The newest data acquisition instrument of the Investigation Department of Kantonspolizei Zürich consists of a kinematic LiDAR system, the RIEGL VP-1 Helipod, and a fully integrated camera system to acquire 3D measurement and image data from the involved objects as well as the sourroundings.

Large-Scale Data Acquisition

The scanner has a 330° field of view and can be operated by one person sitting in the car and using the laptop. The VUX-1 operates at an extremely high pulse repetition rate and delivers up to 500,000 measurements per second. Scan and image data are stored on the laptop for postprocessing in the office.

„Thus we are able to acquire large-scale data of the concerned area that can be visualized in colored 3D pictures“, said Thomas Stutz, specialist in the department „Unfallfotodienst“ of Kantonspolizei Zürich. He is operating the new mobile scanning system in the field.

Data acquisition at 30 km/h driving speed results in really convincing data. For an overview without the need of highly detailed data, driving speeds up to 80 km/h are possible. With the beginning of 2016, the scanner officially will be used for data acquisition, before it will be tested in various trainings to ensure that the crew is familiar with its use in different emerging situations. The system itself is already officially used in the new police helicopter for airborne data acquisiiton – the basically intended purpose of the RIEGL VP-1. There the system is used to acquire data of large areas, for example after train crashes, plane crashes, floods or other natural disasters.

On the Road and in the Tunnel

The new police car acting as platform for the VP-1 is used, when complete road tracks have to be surveyed and the helicopter isn’t the ideal choice. Flights are rather expensive and – of course – noisy. And within a tunnel helicopters‘ can’t never be used.

The advantage of mobile scanning is, that it’s possible to survey the crash scene after the investigation team has done their work; for example if the bureau of investigation asks for the exact data of the street or the prosecution wants to get a map of the site afterwards.    

Multi-million Dollar Helicopter

Stutz outlines, that the new system doesn’t substitute the work of the police forces on site, like forensics. Costs for the additional application of the VP-1 on the police car are stated with 40,000 Swiss Frank for the mounting equipment and the four additional cameras on the car roof.

The Laser Scanning System itself is the kinematic system used for the new police helicopter, which was presented last October. Thus, there were no additional costs to bear. The new helicopter was updated for a sum of 2.1 millions Swiss Frank to meet the requirements oft he Kantonspolizei Zürich; 275,000 Swiss Frank of this for the VP-1 Helipod. Both, the helicopter and the mobile scanning police car are based in Dübedorf.
