INVESTIGATION OF GEOMETRIC PERFORMANCE OF AN INDOOR MOBILE MAPPING SYSTEM
Mobile Laser Scanning Evaluation Viametris iMS3D Point Cloud Indoor Modeling
2018/6/4
Up-to-date and reliable 3D information of indoor environments is a prerequisite for many location- based services. One possibility to capture the necessary 3D data is to make use of Mobile Mapping Sys...
DETERMINING GEOMETRIC PARAMETERS OF AGRICULTURAL TREES FROM LASER SCANNING DATA OBTAINED WITH UNMANNED AERIAL VEHICLE
UAV LiDAR orchards tree height alpha-shape
2018/6/4
The estimation of dendrometric parameters has become an important issue for agriculture planning and for the efficient management of orchards. Airborne Laser Scanning (ALS) data is widely used in fore...
METHODS FOR THE AUTOMATIC GEOMETRIC REGISTRATION OF TERRESTRIAL LASER SCANNER POINT CLOUDS IN FOREST STANDS
Terrestrial laser scanning forest stands registration sphere extraction tree axes
2016/2/29
A combined analysis of multiple terrestrial laser scanner point clouds recorded from different positions requires a geometric
registration of these scans. In most applications of terrestrial laser s...
Simple geometric criterion to predict the existence of surface modes in air-core photonicbandgap fibers
Fiber design and fabrication Fiber optics optical communications
2015/8/11
We propose a simple geometric criterion based on the size of the core relative to the photonic crystal to quickly determine whether an aircore photonic-bandgap fiber with a given geometry supports sur...
