Description
Summary:Recently, the development of geospatial information acquisition technology has been accelerating. Interest in this technology as a way to solve the problem of labor shortages in the forest sector is increasing. In this study, a forest survey was conducted by acquiring data on trees using a laser scanner and detecting individual trees through processing and analysis. Data on the study site were acquired using terrestrial and drone-mounted laser scanners, and a georeferencing point cloud was effectively created through data processing. Diameter at breast height, tree height, crown, and crown-based height were effectively measured by removing the ground from the point cloud data generated in the forest area and classifying individual trees. In addition, we suggest that water pipe measurement is possible through the combination of drone-mounted laser scanner and terrestrial laser scanner data. The existing volume calculation method using a timber volume table and the method using a point cloud were compared. For this comparison, we propose a method of calculating the timber volume using the point cloud.
