End-to-end network-based complex plant structure point cloud completion method and system

This invention discloses a method and system for point cloud completion of complex plant structures based on an end-to-end network. The method constructs a hierarchical geometric encoder to extract and fuse multi-scale geometric features and global shape context features from an incomplete input tree point cloud. A seed generator then generates a coarse point cloud containing the main skeleton of the tree. A cascaded tree growth module progressively upsamples the coarse point cloud, and dynamic deformation constraints ensure that the upsampling process conforms to the natural growth pattern of trees, ultimately outputting a structurally complete and realistically shaped tree point cloud. Furthermore, this invention addresses the scarcity of real, complete tree point cloud data by fusing UAV and ground-based LiDAR scanning data, providing high-quality supervisory data for model training. This effectively solves the problems of insufficient semantic understanding, loss of detail, and morphological distortion in existing point cloud completion methods when dealing with complex tree branch structures, significantly improving completion accuracy and morphological fidelity.

A Real-Time Bending and Shaping Method for Virtual Plants Based on Adjustable Stiffness Weights

This invention provides a real-time bending and shaping method for virtual plants based on adjustable stiffness weights. The method involves configuring virtual plant parameter information and generating a parameterized plant model. The parameter information includes at least plant parameter information, plant control parameter information, and environmental parameter information. When the interactive mode is activated and the plant end is dragged, the end of the plant model is acquired and fixed at the target dragged position. Based on the target dragged position, the dragged virtual plant structure undergoes weighted inverse dynamic bending processing and interpolation. Based on the updated dragged virtual plant structure, other branch structures of the virtual plant are updated synchronously. The overall updated virtual plant structure is subdivided and subjected to Catmull-Rom curve interpolation. The interactive mode is then terminated, and the currently updated virtual plant structure is solidified. This invention uses gradual stiffness, mass curves, and weak bending moment constraints to make the bending shape of the virtual plant highly similar to the stress on real branches.
