The application discloses a feature-driven point cloud completion method and system for a CAD parameterized model, relates to the technical field of three-dimensional geometry processing and computer vision, and comprises the following steps: constructing a multi-source feature line collection and standardization system, obtaining feature line candidates through multiple paths such as analysis of CAD information, mesh point cloud geometric clues and interactive editing rules, and outputting a unified format feature representation after consistency evaluation, cleaning and repairing; designing a local feature extraction method based on adaptive weights of multiple relationships, dynamically adjusting weights according to the relationship between target points and neighbor points in three-dimensional space and high-dimensional feature space in a DGCNN framework, and quantifying the contribution of each neighbor point to the local feature of the target point; and proposing a feature line deep information injection technology, fusing feature line geometric information into a point cloud completion deep learning model through an encoder, using a feature line weighted chamfer distance loss function to strengthen the fidelity of boundary and acute angle regions, and effectively improving the accuracy and geometric detail retention capability of point cloud completion.

This invention discloses a method and system for completing sensitive data flow paths in power information networks. The method includes: estimating the power system state using weighted least squares based on acquired power information network operation data to obtain a standardized system state vector; constructing a power information network graph based on the standardized system state vector and acquired power information network topology data; and completing paths using a trained topology-enhanced dynamic perception graph neural network model based on the power information network graph to obtain a completed power information network graph. This invention solves the problem of insufficient global topology perception in existing methods. Furthermore, through end-to-end link prediction task design, it significantly improves the accuracy and topology rationality of path completion, providing more reliable technical support for the secure operation and maintenance of power information networks.
