Abstract

The invention discloses an automatic building drawing information extraction method and system based on an image recognition technology, and the method comprises the steps: carrying out manual marking of a matching anchor point and a keyword character region of each building drawing template in advance, and obtaining a type matching template of a matching type template library; identifying the type matching template with the highest matching degree, and finding a plurality of component sub-matching templates matching the type template; extracting contour information of a to-be-recognized building drawing, performing component matching when each piece of contour information matches the sub-matching template of the component, and identifying component information of the to-be-recognized building drawing; or comparing each component sub-matching template in the component sub-matching templates with the contour of the architectural drawing to be identified so as to find the component information of the to-be-recognized architectural drawing; and intercepting the component information of the to-be-recognized architectural drawing, identifying the non-components of the to-be-recognized architectural drawing by using an SSD algorithm, and forming digital information of the to-be-recognized architectural drawing.

Description

technical field [0001] The invention relates to the recognition technology of building drawing information, in particular to a method and system for automatically extracting building drawing information based on image recognition technology. Background technique [0002] The tables of industrial drawings generally contain words, letters and various symbols, and there are various combinations of words, letters and symbols. In general, we call the content of text, letters and the combination of the two as normal areas, and the content containing symbols and upper and lower marks as abnormal areas. When converting paper-based industrial drawing forms into computer-editable forms , two methods can be used: general-purpose character recognition technology and high-precision character recognition technology. [0003] 202110482907.6 discloses an image recognition method for engineering drawings, including: obtaining engineering drawing data; preprocessing the engineering drawing d...
