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
font style='font-size:12px;'>
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...

2014/4/25
In laser scanner architectural surveying it is necessary to extract orthogonal projections from the tridimensional model, plans, elevations and cross sections. The paper presents the workflow of archi...
THE DIRECT REGISTRATION OF LIDAR POINT CLOUDS AND HIGH RESOLUTION IMAGE BASED ON LINEAR FEATURE BY INTRODUCING AN UNKNOWN PARAMETER
Airborne LiDAR Linear Feature Registration
font style='font-size:12px;'>
2014/4/28
The registration between optical images and point clouds is the first task when the combination of these two datasets is concerned.
Due to the discrete nature of the point clouds, and the 2D-3D tran...
Detection of model-based Individual Conifer Tree Crown and Estimation of Tree Height Using LiDAR Point Clouds
