A BIM automatic modeling system based on image recognition machine learning

Abstract

The invention relates to a BIM automatic modeling system based on image recognition machine learning. The problems of engineering project BIM technology modeling automation and intelligentization areeffectively solved. Geometric features and attribute features of corresponding components involved in existing highway engineering design specifications, a data acquisition determination information extraction range and feature matching in a data processing image recognition process are matched. According to the extraction range and the organization form, preliminary induction and arrangement arecarried out according to the specialties of roadbeds, road surfaces, bridges, culverts and tunnels, data processing is carried out, and supplementary data connection is carried out. According to the component feature information and the association information between the components, corresponding terrain and geological information is fused, and a BIM model of a corresponding engineering entity isintelligently generated; attribute information exporting is carried out on key parts, important parts and complex parts of the BIM model, back calculation verification is carried out on the attributeinformation and corresponding information extracted from an original drawing, and the position of a model component is rapidly positioned. The device is easy to install and use, and labor, time and economic cost are reduced.

Description

technical field [0001] The invention relates to the field of BIM technology modeling automation and intelligence, in particular to a BIM automatic modeling system based on image recognition machine learning. Background technique [0002] Years of development of BIM technology have proved that BIM technology has and will continue to lead the information revolution in the field of engineering construction. With the gradual deepening of the application of BIM technology, the traditional structure in the field of engineering construction will be broken, and a new information technology-led Architecture will take its place. As a carrier of information technology, the BIM model endows engineering entities with "digital life", is the core of realizing "one model for multiple purposes, one model to the end, and one-key management" in the field of engineering construction, and is the "key to comprehensively understand engineering entities". "Past life and present life" and "appearan...

Problems solved by technology

[0003] Based on the above-mentioned consensus, the field of engineering construction informatization is currently advancing according to the principle of BIM model first, but it has not been deeply applied in the whole life cycle of engineering projects and the operation and maintenance of existing engineering entities in China. The reason is The main manifestations are as follows: On the one hand, the currently popular BIM modeling software in China is mainly from foreign manufacturers, such as Autodesk and Bentley, etc. Foreign software manufacturers have strong fine modeling capabilities, but they still lack integration with Chinese engineering practices. Especially from the integration of norms, standards and management models

On the other hand, due to the low design cost, frequent changes and rough management mode in the construction process of domestic engineering projects, the design quality and design depth of the BIM model of the design institute are limited. At this stage, on the premise of ensuring the fineness of the BIM model, the research on the automation and intelligence of BIM technology modeling has not made further progress. No public reports
