Embodiment Construction

[0028] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0029] Such as figure 2 As shown, the computer program flow of the method for identifying and reviewing drawings of construction industry engineering CAD drawings of the present invention is summarized as follows: first, input all graphic element data of drawings; secondly, perform graphic element processing operations; then, perform graphic construction operations; then, establish relationship; finally, cloud verification. Corresponding to the flow chart, the method for identifying and reviewing drawings of construction industry engineering CAD drawings of the present invention, the specific steps are as follows:

[0030] Step S1. The user opens the CAD drawing t...

Abstract

The invention discloses an identifying and graph-auditing method of a building industry engineering CAD drawing. The method comprises the following steps: S1, parsing CAD drawing data, and extractingpixels; S2, denoising and normalizing the pixels; S3, constructing graphics, which need to be identified, by the normalized pixels; S4, establishing determined relationships among the graphics; S5, inversely deducing undetermined relationship graphics through the graphics of the determined relationships to exclude suspected graphics; and S6, submitting the graphics and the data to a service end for rule verification, and returning a verification result. According to the identifying and graph-auditing method of the drawing of the invention, all CAD-format drawings can be identified, whether theCAD drawings drawn by construction industry designers go against national standards can be judged, graph-auditing efficiency is improved, and manpower and time consumed for graph-auditing are saved.

Description

technical field [0001] The invention relates to the technical field of AutoCAD drawing identification, in particular to a method for identifying and reviewing engineering CAD drawings in the construction industry. Background technique [0002] According to the relevant regulations of the state, the construction drawings of various construction projects, municipal projects, special projects, etc., according to their project grades, must pass the examination of a professional review agency with corresponding qualifications before the construction is permitted. The review of construction drawing design documents of construction projects is a basic construction procedure that must be carried out and complied with in construction projects. Projects that fail the policy review will not be subject to technical review. Projects without survey and review will not be reviewed for construction drawing design documents. Construction permits shall not be applied for projects without co...
