| Outline of Final Research Achievements |
In this study, we built a hardware system for 3D measurements based on the 2D range sensor for the purpose of the development of an automatic mapping system of 3D vegetation. Furthermore, we devised software systems: a system for conversion from 2D distance data to 3D point cloud, a system for the cooperative distance measurement based on a range sensor and an electric camera platform, a 3D mapping system based on the point cloud derived from vegetation, an automatic estimate system of the tree shape characteristics based on the 3D map.
From the result of the evaluation experiments, we quantitatively confirmed a certain effectiveness of our system as an automatic measurement system for an automatic mapping of 3D vegetation. In our future plan, we will try to improve the precision of measurement to fit our system for practical use.
