Latest Patents

Heterogeneous Image Registration Method and System. This invention detects edges in collected images and extracts contour segments using a curvature scale space strategy. It identifies feature points through global and local curvature analysis, then uses nearby curvature minima to determine sampling points and auxiliary features. These features form triangles used to calculate angle-bisector vectors and principal directions. The method is designed to provide accurate, adaptable image registration for electrical equipment.

High-Precision Identification Method and System for Substations. This invention uses a Mask R-CNN object-recognition model to analyze images of substation equipment. It then applies information entropy and a semantic decision tree to refine the initial recognition results based on relationships among different objects. The system aims to improve identification accuracy and support the development of inspection robots.
