Automated individual tree crown delineation from LIDAR data using morphological techniques
In current tree crown delineation from LiDAR data, treetops and 3D geometric shapes of tree crowns are frequently extracted from LiDAR-derived Crown Height Model (CHM) and used as references to localize and delineate crowns. However, it is difficult to detect deciduous treetops and delineate deciduous tree crowns. The 3D shape of a crown, which can be derived from CHM, may be taken as a half el...
متن کاملTrends in Automatic Individual Tree Crown Detection and Delineation - Evolution of LiDAR Data
Automated individual tree crown detection and delineation (ITCD) using remotely sensed data plays an increasingly significant role in efficiently, accurately, and completely monitoring forests. This paper reviews trends in ITCD research from 1990–2015 from several perspectives—data/forest type, method applied, accuracy assessment and research objective—with a focus on studies using LiDAR data. ...
متن کاملA Region-Based Hierarchical Cross-Section Analysis for Individual Tree Crown Delineation Using ALS Data
In recent years, airborne Light Detection and Ranging (LiDAR) that provided three-dimensional forest information has been widely applied in forest inventory and has shown great potential in automatic individual tree crown delineation (ITCD). Usually, ITCD algorithms include treetop detection and crown boundary delineation procedures. In this study, we proposed a novel method called region-based...

متن کاملComparison of Individual Tree Crown Detection and Delineation Methods
Efficient forest management increases the demand for detailed, timely information. High spatial resolution remotely sensed imagery provides viable sources and opportunities for automated forest interpretation at an individual tree level. Recent research, which aims at providing tree-based forest inventory measurements, has considered automatic individual tree crown detection and delineation. A ...
