A MORPHOLOGICAL RECONSTRUCTION ALGORITHM FOR SEPARATING OFF-TERRAIN POINTS FROM TERRAIN POINTS IN LASER SCANNING DATA
LIDAR morphological reconstruction terrain points off-terrain points DTM
2015/8/13
During the last decade various techniques have been proposed to extract the ground surface from airborne LIDAR data. The basic
problem is the separation of terrain points from off-terrain points whi...
USING STEREO IMAGES TO DENSIFY LIDAR DATA POINTS AT WHERE NEEDED
Image Building Application Algorithm
2015/6/1
For many applications, dense Lidar data is often needed. For instance, for telecommunication antenna network design, 1 meter
spacing Lidar data would be needed for downtown area of a big city. Howev...
A NOVEL IMAGE REGISTRATION ALGORITHM FOR SAR AND OPTICAL IMAGES BASED ON VIRTUAL POINTS
