A 3D Visual Management System of Building Decoration Construction Based on BIM Technology

基于整体性与一致性原则,在BIM技术支持下构建含采集层、数据层、平台层与应用层的建筑装修施工三维可视化管理系统。针对以往系统运行中信息采集、处理与可视化等算法的不足,采用相似度特征匹配方法,进行建筑装修施工三维可视化信息特征配准,得到建筑装修施工三维特征的BIM信息融合判决统计量,执行对三维特征BIM信息融合及特征调度的任务。结合建筑装修施工三维可视化视觉信息特征匹配方法,构建建筑装修施工三维可视化视觉图像的自适应滤波模型,实现建筑装修施工三维可视化视觉重建。通过分析三维可视化视觉信息函数,构建三维可视化信息重构BIM信息库模型,直观、清晰而又无误地进行抽象化的建筑装修施工信息的传达,保证建筑装修施工三维可视化信息管理能力。系统测试结果表明,采用该方法进行建筑装修施工三维可视化管理的实时性较好,现场信息采集和自动分析能力较强。

Based on the principle of integrity and consistency, with the support of BIM technology, a three-dimensional visual management system for building decoration construction is constructed, including acquisition layer, data layer, platform layer and application layer. In view of the shortcomings of the existing algorithms such as information collection, processing and visualization in previous system operation, the similarity feature matching method is used to carry out the 3 D visual information feature registration of building decoration and construction. The BIM information fusion judgment statistics of the 3 D features of building decoration and construction is obtained, and the task of BIM information fusion and feature scheduling of the 3 D features is performed. Combined with the feature matching method of 3 D visual information of building decoration and construction, the adaptive filtering model of 3 D visual image of building decoration and construction is built to realize 3 D visual reconstruction of building decoration and construction. By analyzing the visual information function of 3 D visualization, the BIM information base model of 3 D visualization information reconstruction is constructed. It can convey abstract building decoration and construction information intuitively, clearly and unmistakably, and ensure the building decoration and construction 3 D visualization information management ability. The system test results show that this method has better real-time performance and strong ability of site information collection and automatic analysis in 3 D visualization management of building decoration and construction.
