|Title:||3D segmentation of forest structure using a mean-shift based algorithm|
Gomes Pereira, L.
|Keywords:||Airborne laser scanning|
Forest vertical structure
|Abstract:||Consistent and accurate information on 3D forest canopy structure is required by many applications like forest inventory, management, logging, fuel mapping, habitat studies or biomass estimate. Com- pared to other remote sensing techniques (e.g., SAR or photogram- metry), airborne laser scanning is an adapted tool to provide such information by generating a three-dimensional georeferenced point cloud. Vertical structure analysis consists in detecting the number of layers within a forest stand and their limits. Until now, there is no approach that properly segments the different strata of a forest. In this study, we directly work on the 3D point cloud and we propose a mean shift (MS) based procedure for vertical forest segmentation. The approach that is carried out on complex forest plots improves the discrimination of vegetation strata.|
