Multispectral Airborne Laser Scanning provides a new opportunity for airborne data collection. It provides high-density topographic surveying and is also a useful tool for land cover mapping. Use of a...
During the last 20 years, airborne laser scanning (ALS), often combined with multispectral information from aerial images, has shown its high feasibility for automated mapping processes. Recently, the...
Pedestrian flow is much less regulated and controlled compared to vehicle traffic. Estimating flow parameters would support many safety, security or commercial applications. Current paper discusses a ...
Ground spatial data acquisition is a key technology in digital city engineering, It is important to improve the efficiency of data acquisition. The main purpose of this paper is to develop vehicle-bor...
Recent developments in the utilisation of close range laser scanning (lidar) in geology have seen the increased use of virtual outcrop data. The remote mapping of rock properties within the virtual ou...
Within this paper an approach of calibration for a terrestrial laser scanner with two mirrors driven by two galvanometers is presented. This includes a mathematical model for the interior of the laser...
Technological development has brought a new instrument for 3D object survey in every field, and laser scanner is the latest of these instruments. In this time, laser scanners has been used for obtain ...
Glaciers are interesting phenomena to scientists, mountaineers and tourists. Glaciers have a great impact on the local economy, power generation and water supply. Furthermore, the behaviour of glacier...
As glaciers are good indicators for the regional climate, most of them presently undergo dramatic changes due to climate change. Remote sensing techniques have been widely used to identify glacier sur...
Canopy height distributions were created from small-footprint airborne laser scanner data for mature coniferous forest in two forest areas in Norway. In total, 82 and 70 georeferenced field sample plo...
Filtering non-terrain points from raw laser scanning data is the most important goal to improve productivity in DTM generation.Filtering algorithms are built on assumptions about what discriminates te...
There is an increasing interest of the scientific community in the generation of 3D facade models from terrestrial laser scanner (TLS) data. The segmentation of building facades is one of the essentia...
This work focuses on the use of terrestrial laser scanner (TLS) in the characterization of volcanic environments. A TLS survey of the Vesuvius crater (Somma-Vesuvius volcano, Italy) allows the constru...
Tracking pedestrians is an important topic in the field of pattern recognition and image understanding due to its various applications. Although video-based approaches have been studied for decades, ...
Today's car navigation systems have reached a high level of maturity, using huge map databases with a high coverage and up-to-dateness. However, as additional applications gain importance, such as ad...
