A user interface module, a basic primitive identification rule module, a building element identification rule module, an engineering parameter extraction rule module, a basic primitive identification module, a building element identification module and an engineering parameter extraction module are adopted; and the subway construction drawing and engineering parameter automatic identification method is specially used for implementing a technical scheme for identifying engineering parameters related to the risk management in an engineering drawing on the aspect of subway engineering construction and the data basis is provided for a further risk management technical scheme.

Description

technical field [0001] The invention belongs to the technical field of identification of engineering drawings, in particular to a method for automatic identification of subway construction drawings and engineering parameters. Background technique [0002] Engineering drawing recognition is a branch of the field of graphic recognition. The research in the field of graphic recognition involves the recognition of various drawings and symbolic information such as mechanical design drawings, logic circuit diagrams, maps, architectural drawings, musical scores, and LOGO. According to the different properties of design information carriers, engineering drawings can be divided into: paper engineering drawings and vector graphics drawn by CAD software. The recognition technology for paper drawings mainly includes: the raster image vectorization technology formed by scanning, the recognition method of basic graphic elements (lines, arcs, dimension lines, etc.), professional graphic el...
