3D IMAGE BASED GEOMETRIC DOCUMENTATION OF A MEDIEVAL FORTRESS
3D model Orthophoto UAV Laser Scanning Photogrammetry
2019/3/4
The detailed and thorough documentation of monuments is a rather complex process that requires the application of the best available state of the art techniques in order to preserve, restore, promote ...
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...
3D CATENARY CURVE FITTING FOR GEOMETRIC CALIBRATION
3D catenary model least square fitting parameter correlation hanging power cables
2014/6/5
In modern road surveys, hanging power cables are among the most commonly-found geometric features. These cables are catenary curves that are conventionally modelled with three parameters in 2D Cartesi...
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...
