Research Topic: Automatic tree structure reconstruction and tree species recognition from terrestrial laser scanning data
Brief Introduction: Tree species information acts as an essential input for estimating forest carbon capture and storage. However, present methods rely on skilled workers to identify tree species manually, which is time-consuming and limited to small-scale region. Therefore, new techniques for classifying tree species in an automatic and efficient way are desperately demanded. Terrestrial laser scanning (TLS) is a cutting-edge technique that can efficiently acquire highly accurate and detailed three-dimensional point cloud data, and this makes it possible for describing three-dimensional tree structures with unprecedented details. This study will first investigate how to use machine learning approaches to reconstruct tree structure from TLS data in a more accurate and automatic way, and then develop methods of identifying tree species from the structure information. This study will be beneficial for reducing uncertainty in estimates of forest carbon stocks as well as making the massive-scale remote sensing from TLS data practical.
