AI Technical Summary
Existing technologies struggle to effectively address the issues of inconsistent quality, complex and diverse information formats, and strong implicit semantic relationships in scanned drawings. This makes it difficult to digitize and implement drawing information, hindering the formation of a structured data system and limiting the reuse and value release of drawing knowledge.
A multimodal structured parsing method is adopted, including image preprocessing, primitive detection and vectorization, arbitrary-direction text detection and multimodal semantic fusion. Combining computer vision, optical character recognition and natural language processing technologies, the association between text and graphics is established, and a topological structure representation is constructed and stored in the database.
It enables complete extraction and semantic understanding of drawing information, supports equipment management, process traceability and intelligent retrieval, and enhances the digital value of drawing assets.
