LiDAR is a consolidated technology for topographic mapping and 3D reconstruction, which is implemented in several platforms On the other hand, the exploitation of the geometric information has been co...
OPTIMAL INFORMATION EXTRACTION OF LASER SCANNING DATASET BY SCALE-ADAPTIVE REDUCTION
Multi-scale Surface variation Radial basis function Just-Noticeable-Difference Degradation
2018/5/16
3D laser technology is widely used to collocate the surface information of object. For various applications, we need to extract a good perceptual quality point cloud from the scanned points. To solve ...
Interactive Trunk Extraction from Forest Point Cloud
Terrestrial Laser Scanning Forest, User-Interaction
2014/7/30
For forest management or monitoring, it is required to constantly measure several parameters of each tree, such as height, diameter at breast height, and trunk volume. Terrestrial laser scanner has be...
Semi-automatic extraction of sectional view from point clouds – The case of Ottmarsheim's abbey-church
Cultural heritage terrestrial laser scanning automation extraction reconstruction assessment
2014/7/30
Today, elevations or sectional views of buildings are often produced from terrestrial laser scanning. However, due to the amount of data to process and because usually 2D maps are required by customer...
Enhancing far-field thermal emission with thermal extraction
Enhancing thermal emission thermal extraction
2015/8/7
The control of thermal radiation is of great current importance for applications such as energy conversions and radiative cooling. Here we show theoretically that the thermal emission of a finit...
