轻量化实景三维模型质量评定方法

以基于实景三维模型的BIM设计为导向,按照土建工程设计各阶段的不同需求,兼顾模型几何精度和纹理质量,提出轻量化实景三维模型数据质量评定方法。解决了轻量化后的实景三维模型数据质量控制的难题,为其广泛应用到BIM设计中打下坚实基础。改变了传统测绘数据成果的交付形式,从勘察测绘环节促使设计人员使用BIM技术,进而加快BIM技术的普及和应用,加强BIM技术应用的深度和广度,最终实现BIM技术在建筑行业全生命周期过程中的普及和推广。

Quality Evaluation Method of Lightweight Live 3D Model

Guided by BIM design based on the live 3D model,according to the different demands of each stage of civil engineering design,and also considering the geometric accuracy and texture quality of the model,the data quality evaluation method of lightweight live 3D model is proposed to solve the difficulties of the data quality control of live 3D model after lightweight.The solid foundation is laid in order to make it widely applied in BIM design.The traditional delivery form of surveying and mapping data results is changed.The designers are promoted to use BIM technology from the surveying and mapping links so as to speed up the popularization and application of BIM technology.The depth and breadth of BIM technology application are strengthened.Finally,the popularization and application of BIM technology are realized in the full-life circle process of construction industry.
