360. The 360 Survey Module is designed to work with the new scanning cameras like Panoramo and Panoramo SI.

360

When 360 is paired with a Lite Reporting License, it launches the Panoramo scanner and also creates Mini-movies. The IPF file is created and can be played back and reviewed. The powerful analysis tools built into 360 are combined with a Full Reporting License to create accurate survey data from three different pipe views. The Full View resembles the traditional survey movie with travel through the pipe controlled by your computer mouse. You can travel fast, slow, pan and tilt or zoom to problems.

Intelligent Robot for Mapping Applications in 3D. Verification of rock mass quality. LiDAR (Light Detection and Ranging) is a technology for remote sensing using an optical method to measure spreading of light to determine the distance to an object.

Verification of rock mass quality

This film gives a brief introduction to the use of LiDAR technology in underground construction in the Lørentunnel, a drill-and-blast tunnel in Oslo. The LiDAR technology instrument emitts a beam of light and measures the phase shift of the returning beam in order to accurately position the target. It measures x, y, z and i (reflectance). The particular unit considered most appropriate for tunnels has a range of 120 m, acquires over 900,000 points/sec and has a near-spherical field of view. LiDAR technology utilize 3D laser scanning. LiDAR scanning can be made from the air (airborne scanning), from landbased vehicles (mobile) or from stationary, ground based scanners. Mapping Abysses. While clearing several months' worth of accumulated bookmarks, we rediscovered an article from The New York Times about laser scanning in Glasgow — or to be more precise: laser scanning the city itself.

Mapping Abysses

A few years ago, we read, a group from the Glasgow School of Art “began surveying a swath of the center of Glasgow, along the River Clyde, creating 3-D digital representations of some 1,400 buildings and dozens of streetscapes.” The project led to commissions from the Scottish government's heritage agency to scan other historical landmarks in the country.

The solutions for a tunnel survey can be optionally combined or applied separately if needed. The complete service package is available, divided in following sections: TSC Tunnel Scanner. Laser crack measurement system (LCMS), Advanced Vision Technology 3D. Pavemetrics Laser Tunnel Scanning System (LTSS) uses multiple high-speed laser scanners to acquire both 2D images and high-resolution 3D profiles of tunnel linings.

Laser crack measurement system (LCMS), Advanced Vision Technology 3D

The LTSS is 100 times faster and 10 times more accurate than typical LIDAR technology; it can scan a full tunnel vault (24m) at 1-mm image resolution and 3D data at acquisition speeds of up to 20km/h.

Evaluation of Sensors and Mapping Approaches for Disasters in Tunnels. In april 2013 we participated at a training exercise of the slovenian and austrian fire brigade in a highway tunnel at the Loiblpass.

Evaluation of Sensors and Mapping Approaches for Disasters in Tunnels

The goal was to evaluate state of the art sensors and mapping algorithms under harsh environment. Therefore a sensor platform was developed to process the incoming data for live coverage and recording for evaluation steps. This platform was mounted on "Odin", a military graded ground robot developed by the Communication, Information Processing and Ergonomic (FKIE) division of the German Fraunhofer Gesellschaft. Odin is a robust, highly versatile platform for effective support of first responders. The robot can be equipped with all kinds of payloads, just as needed by different application fields such as reconnaissance or fire extinguishing. The evaluated mapping algorithms were: Hector SLAM The tunnel portal is mapped well because it provides enough diverse structures for scan matching.

Osher and J. A. Sethian, has attracted much attention as a method that realizes a topology free active contour modeling. This method utilizes an implicit representation of a contour to be tracked, and is able to handle the topological change of the contour intrinsically.
