Modeling of 3D Forest Scenes by Laser Scanning and Air Photo Data
Abstract
Purpose: Visualization of vegetation in three-dimensional landscape scenes is not a trivial task because different tree species have different branch structure. General purpose packages do not let you develop vegetation models unless you have special skills. Specialized packages like GIS use generalized graphic primitives to describe the shape of a tree crown. The problem is to develop branching rules for both coniferous and broad-leaved species of trees. Results: Simulation of 3D-scenes of forest areas is described, based on airborne laser scanning data and aerial photographs providing the information about the shape of a tree crown, height of the forest canopy and type of the terrain using the classification rules for the data of the laser scanning. These rules are based on the decomposition of the original cloud of points into 3D-cubes called voxels. Branching rules have been developed for different tree species on the base of L-systems used to draw the main skeleton of a tree model. Space Colonization algorithm was used for the detailed modelling of the tree crown. Practical relevance: The obtained laser scanning data classification rules let you design high-precision models of natural forest landscape scenes for data visualization.Published
