Fast Automatic Precision Tree Models from Terrestrial Laser Scanner Data
This paper presents a new method for constructing quickly and automatically precision tree models from point clouds of the trunk and branches obtained by terrestrial laser scanning. The input of the method is a point cloud of a single tree scanned from multiple positions. The surface of the visible parts of the tree is robustly reconstructed by making a flexible cylinder model of the tree. The ...
متن کاملTowards Automatic Feature Line Modelling from Terrestrial Laser Scanner Data
For the representation of objects or scenes different representation forms are utilised. While for some tasks a point cloud representation or a triangulation of the point cloud is sufficient, a boundary representation or a wireframe model is necessary for other applications. For these the determination of feature lines is essential. In the past the generation of feature lines was a manual task....
متن کاملAutomatic Building Extraction from Terrestrial Laser Scanning Data
The extraction of building from the huge amount of point clouds with different local densities, especially in the presence of random noisy points, is still a formidable challenge. In this paper, we present a complete strategy for building extraction from terrestrial laser scanning data. First, a novel segmentation method is proposed to facilitate the task of building extraction. The points are ...
متن کاملA Voxel-based Technique to Estimate the Volume of Trees from Terrestrial Laser Scanner Data
The precise determination of the volume of standing trees is very important for ecological and economical considerations in forestry. If terrestrial laser scanner data are available, a simple approach for volume determination is given by allocating points into a voxel structure and subsequently counting the filled voxels. Generally, this method will overestimate the volume. The paper presents a...
متن کاملTerrestrial laser scanning to estimate plot-level forest canopy fuel properties
This paper evaluates the potential of a terrestrial laser scanner (TLS) to characterize forest canopy fuel characteristics at plot level. Several canopy properties, namely canopy height, canopy cover, canopy base height and fuel strata gapwere estimated. Different approaches were tested to avoid the effect of canopy shadowing on canopy height estimation caused by deployment of the TLS below the...
