Deep learning based on prior geometric features for the segmentation of individual tree point cloud components
“Lidar provides new technical support for non-destructive estimation of tree structural parameters and aboveground biomass. The research team constructed a large-scale dataset containing 713 individual trees, introduced the Point Transformer V3 network, and optimized the prior geometric features to achieve high-precision segmentation of multiple tree species and individual tree components, providing technical support for accurate estimation of tree structural parameters.”
