MULTIGRID CELL SHAPE EVALUATION IN DTM FILTERING OF MOBILE LIDAR POINT CLOUDS
Point cloud Mobile LiDAR Digital terrain models Filtering Delaunay triangulation
2018/11/9
The georeferenced information acquisition for large scales digital terrain models generation is usually a rather time-consuming and costly process. The use of point clouds gathered by mobile LiDAR sys...
A VOXEL-BASED FILTERING ALGORITHM FOR MOBILE LIDAR DATA
Mobile LiDAR filtering voxelization upward growing curvature
2018/5/15
This paper presents a stepwise voxel-based filtering algorithm for mobile LiDAR data. In the first step, to improve computational efficiency, mobile LiDAR points, in xy-plane, are first partitioned in...
FILTERING OF AIRBORNE LASER SCANNER DATA BASED ON SEGMENTED POINT CLOUDS
Segmentation Filtering Laser scanning LiDAR
2015/8/13
The extraction of points on the bare Earth from point clouds acquired by airborne laser scanning is the most time consuming and
expensive part in the production of digital elevation models with laser...
Self-Homodyne 10 Gbit/s PSK Receiver based on Stimulated Brillouin Amplification and Electrical Filtering
Optical communications Optical processing
2015/6/10
We demonstrate the first self-homodyne coherent detection of 10 Gbit/s PSK signals using Brillouin amplification of the optical carrier. Performance close to the ideal homodyne receiver is obtained by...
