Nowadays, laser scanning has become an additional technique for geodetic applications. The use of laser scanners is continuously increasing. Different laser scanners of several companies are available. At the Institute of Geodesy and Photogrammetry (IGP) of the Swiss Federal Institute of Technology Zurich (ETH Zurich), experiences with several scanners were gained. Recently, the focus is on inv...

This paper describes a vision and 3D laser based registration approach which utilizes visual features to identify correspondences. Visual features are obtained from the images of a standard color camera and the depth of these features is determined by interpolating between the scanning points of a 3D laser range scanner, taking into consideration the visual information in the neighbourhood of t...

3D models obtained with advanced survey techniques such as close-range photogrammetry and laser scanner are nowadays particularly appreciated in Cultural Heritage and Archaeology fields. In order to produce high quality models representing archaeological evidences and anthropological artifacts, the appearance of the model (i.e. color) beyond the geometric accuracy, is not a negligible aspect. T...

This paper consists in the presentation of several implementing issues regarding the integration of short range laser scanner with a robot arm – the laser scanning system component of a multifunctional, autonomous, self-adaptive manufacturing platform. One of the most important aspects consists in the synchronisation between the data acquired from the laser scanner and the location data acquire...

In this paper, a numerical study of barrier characterization effects on the high-temperature internal performance of an InGaAsP multi-quantum well laser is presented. The softwareused for this purpose self-consistently combines the three-dimensional simulation of carrier transports, self-heating, and optical waveguiding. The laser model calculates all relevant physical mechanisms, including the...
