HIERARCHICAL HIGHER ORDER CRF FOR THE CLASSIFICATION OF AIRBORNE LIDAR POINT CLOUDS IN URBAN AREAS
Classification Point Cloud Higher Order Random Fields Contextual Lidar Urban
2016/7/28
We propose a novel hierarchical approach for the classification of airborne 3D lidar points. Spatial and semantic context is incorporated via a two-layer Conditional Random Field (CRF). The first laye...
PARALLEL PROCESSING OF BIG POINT CLOUDS USING Z-ORDER-BASED PARTITIONING
Z-order Spatial partitioning Big Data
2016/7/8
As laser scanning technology improves and costs are coming down, the amount of point cloud data being generated can be prohibitively difficult and expensive to process on a single machine. This data e...
ACCURACY OF CROWN SEGMENTATION AND ESTIMATION OF SELECTED TREES AND FOREST STAND PARAMETERS IN ORDER TO RESOLUTION OF USED DSM AND NDSM MODELS GENERATED FROM DENSE SMALL FOOTPRINT LIDAR DATA
Airborne Scanner System Segmentation Aerial photogrammetry Comparative analysis Forestry
2015/12/23
The purpose of this study is to categorize how different surface model resolutions impact the estimation of trees and forest stands parameters: number of recognized trees, crown area, treetop location...
