3D Visual Sustainable Management of Rubber Forest Based on Terrestrial Photogrammetry System

As an important part of agricultural cash crops in Hainan Province, more attention should be paid to monitoring sample plots of rubber trees. We developed a terrestrial photogrammetry system combined with 3D point-cloud reconstruction technology based on the structure from motion with Multiview Stereo method and sample plot survey data. Deviation analyses and accuracy evaluations of quadrat information were performed in the study area, covering different age classes and morphological characteristics, to explore its practical value in monitoring rubber forest sample plots. Furthermore, the relationship between under branch height, diameter at breast height (DBH), and rubber tree volume was explored, and a rubber tree binary volume model was established. Here, we innovatively proposed a planning scheme for a terrestrial photogrammetry system for the sustainable management of rubber forests, to provide a novel solution to the issues faced by current sample plot monitoring practices. In the future, the application of a terrestrial photogrammetry system to other types of forest monitoring will gradually be explored.The following is the data package of our research: 1. The data table in the folder (Coordinate) is the point position coordinate information of our sample shooting image. 2. The data table in the folder (Data) is the data summary table of our study, which includes the measurement value of rubber forest volume, the measurement value of rubber forest DBH, the measurement value of under branch height and the specific information of each rubber tree in 19 sample plots. 3. The data in the folder (Figures) is the relevant illustration in the research paper. Due to some missing data in the process of saving, we have supplemented and uploaded the data of the rubber forest 3D point cloud data obtained by the terrestrial photogrammetry system in the data set.
