| Outline of Final Research Achievements |
In this study, our objective is to develop a new analysis method for 3-D point clouds obtained in forest stands using the terrestrial LiDAR. We developed a rapid and automatic method of dividing point clouds into each individual tree and of subdividing into stem, branch and foliage, and of modeling these organs. We also estimated morphological traits of the organs. We have evaluated several traits such as tree height and stem diameter based on the modeling method and validated the estimation. As a result, the validation showed that our method could accurately estimate those traits. We believe that the developed method in this study is effective for measuring morphological traits and it may be able to replace the traditional forest survey methods.
