Building structure steel bar data analysis and conversion method

Abstract

The invention relates to a building structure reinforcing steel bar data analysis and conversion method, which comprises the following steps of: opening a CAD reinforcing steel bar drawing, inputting an'x 'command to decompose a block object, saving the drawing containing a reinforcing steel bar to be extracted as a DXF format file of any version, and setting a target retrieval box to draw the reinforcing steel bar to be extracted; entity segment information extraction is carried out on geometric primitives in the target retrieval box, and entity segment information of three types of basic primitives including straight lines, circles and arcs is extracted in a classified mode; when at least two repeated geometric primitives exist in the classified entity segments, only any one geometric primitive is reserved; after repeated geometric primitives are removed, the remaining geometric primitives are ranked and drawn, and machining parameters are output. According to the method, full-automatic processing of steel bar data analysis and conversion is achieved, the accuracy rate of direct analysis and conversion results reaches up to 100%, and errors caused by manual graph recognition can be well reduced.

Description

technical field [0001] The invention belongs to the technical field of drawing identification, in particular to a method for analyzing and transforming steel bar data of a building structure based on CAD drawings. Background technique [0002] The annual output of steel bars in my country is about 300 million tons, which is a huge volume. However, traditional steel bar processing is still dominated by simple machines on construction sites, presenting an extensive production method, which is labor-intensive and low in production efficiency. "10 New Technologies in the Construction Industry" listed "processing and distribution technology of formed steel products for construction" as one of the 10 new technologies, and the "List of Reproducible Practices for Intelligent Construction" mentioned the need to realize automatic processing of steel mesh. Therefore, the intelligent processing of steel bars is crucial to the realization of intelligent construction and building industri...

Problems solved by technology

However, this method is time-consuming and labor-intensive, and the quality of the finished steel bar is determined by the effect of manual image recognition. The image recognition mode needs to be transformed and upgraded. The existing 3D conversion method requires 3D modeling. The modeling is difficult, the cycle is long, and the accuracy rate needs to be improved.
