Application to 3D modeling of tree by laser measurement

Abstract

Laser measurement is currently applied to several tasks such as plumbing management, road investigation through mobile mapping systems, and elevation model utilization through airborne LiDAR. Effective laser measurement methods have been well-documented in civil engineering, however few attempts have been made to establish equally effective methods in landscape engineering. By using point cloud data acquired through laser measurement, the data for trees are contained each components of parts (branches, leaves and trunk), which can be recognized detail form of the trees. Therefore, this study focuses on expression of detail 3D model for trees expressing by using the point cloud data, and considers the construction of a library of garden trees extracted from point cloud data. The library would serve as a resource for creating new gardens and simulating gardens prior to conducting repairs. Finally, Models created using point cloud data are informative because simply shaped garden features such as trees are often seen in the 3D industry.
