| Abstract: | Three-dimensional tree models were built based on point clouds from terrestrial LiDAR and the living vegetation volume was estimated. How to patch the cloud data was discussed, and the application of the model in three-dimensional green quantity estimation was introduced, including cloud data de-noising, point cloud data matching, and tree three-dimensional model building. The results proved that using this method to build three-dimensional structural model and to estimate living vegetation volume was feasible. The accuracy could fully meet the living vegetation volume requirements. |
