Architectural drawing automatic recognition method based on boundary scanning algorithm

Abstract

The invention relates to an architectural drawing automatic recognition method based on a boundary scanning algorithm, and the method is characterized in that the method comprises the steps: normalizing a layer in a drawing to a standard layer, and dividing the drawing in the standard layer into an indoor region and a public region; recognizing the spatial features of the indoor area by using a boundary scanning algorithm, and recognizing the spatial features of the public area by using a central axis algorithm; and respectively persisting the recognized spatial features of the indoor area and the spatial features of the public area to XML (Extensible Markup Language). According to the method, the drawings are subjected to informatization processing, and the method has the characteristics of high interactivity, high execution efficiency, low error rate, low repair cost, simplicity in use and the like.

Description

technical field [0001] The invention relates to the technical field of object recognition in architectural drawings, in particular to an automatic recognition method for architectural drawings based on a boundary scan algorithm. Background technique [0002] Drawing recognition is an important part of automatic analysis and design of electrical circuits. At present, the drawing identification of civil residential buildings mainly relies on the manual identification of engineers from various design institutes, and draws electrical and other related drawings with the help of AutoCAD software. However, in order to realize automatic analysis of electrical circuits, designers need to re-interpret the design information from the drawings, perform complex and repetitive calculations based on this, and store the interpretation results in the database, which is extremely inefficient. Due to the different styles of each design institute, the readability of drawings is poor; there is ...

However, in order to realize automatic analysis of electrical circuits, designers need to re-interpret the design information from the drawings, perform complex and repetitive calculations based on this, and store the interpretation results in the database, which is extremely inefficient

Due to the different styles of each design institute, the readability of drawings is poor; there is no supporting management system for drawing information, and the degree of informatization is low; the statistics of key information mainly rely on reading drawings and manual calculations, which is inefficient and has a high error rate; Under the premise of existing national regulations, some simple and repetitive tasks have not been automated. Designers often need to do a lot of simple and repetitive labor, resulting in a lot of waste of human resources and low efficiency; the professionalization of electrical engineers The degree requirements are high, and the cost of training a highly reliable electrical engineer is high, which increases the employment cost of the design institute
