Embodiment Construction
[0019] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0020] The present invention splits architectural drawings from a parametric perspective, understands buildings and architectural drawings through a parametric system, and establishes a flexible and efficient architectural construction drawing information extraction and data organization model based on this, which can avoid data quality caused by automatic identification problem and the efficiency problem of pure manual extraction, and achieved an effective balance between the two. This method establishes a parametric understanding of building data, splits architectural drawings from a parametric perspective, understands buildings and architectural drawings through a parametric system, and establishes a flexible and efficient extraction of building construction drawing information based on this and data organization models.

The invention relates to a pattern recognition method for electronic building construction drawings, and belongs to the technical field of engineering drawing recognition. The method comprises the following steps of: dividing a to-be-recognized electronic building construction drawing according to patterns with different space positions and details, and enabling all the pattern objects to be located under a uniform coordinate system through pattern registration; layering and classifying pattern files corresponding to floors, and associating the pattern files to specific basic patterns on the basis of a mapping relationship of drawing rules according to pattern information required by the drawing rules; and extracting building framework parameters, building component basic parameters and building component extension parameters according to the drawing rules by adoption of an artificial or automatic distinction manner. According to the method, drawings are split through a parameterized angle of view, so that the data quality problem caused by automatic recognition and efficiency problem caused by pure-artificial advancement can be avoided, and effective balance between the data quality and the efficiency is achieved.
Description
technical field [0001] The invention relates to a graphic recognition method of an electronic building construction drawing, belonging to the technical field of engineering drawing recognition. Background technique [0002] Electronic architectural construction drawings have been used for decades, and have accumulated a huge stock of drawing data in the field of construction, especially in my country, which maintains a large number of architectural electronic drawings in various file formats. The three-dimensional building model can be reconstructed based on electronic building construction drawings, which has broad application prospects in the fields of smart cities, real estate management, operation and maintenance, etc. Therefore, graphic recognition and data extraction based on electronic building construction drawings have important market prospects. Architectural components are the basic constituent units of building entities, and the expression of architectural space ...
