Abstract

Embodiments of the invention provide a BIM-based (building information modeling based) road parametric auto-modeling method and system. The method comprises: establishing a topographic scene model using image data and digital elevation model data; breaking a road structure into multiple parts, and acquiring design data of each part; subjecting each part to unitary modeling according to its design data to obtain a corresponding unitary model; assembling the unitary models corresponding to the parts according to preset road construction specifications to obtain a road three-dimensional model; merging the road three-dimensional model with the topographic scene model through a preset algorithm to obtain a merged road real three-dimensional model; correlating the unitary models in the road real three-dimensional model with attribute information, and displaying. The embodiments of the invention also provide a BIM-based road parametric auto-modeling system. The method and system enable automatic modeling of a road and improved modeling efficiency and provide realistic three-dimensional displaying.

Description

technical field [0001] The present invention relates to a highway three-dimensional modeling technology, in particular to a BIM-based road parametric automatic modeling method and system. Background technique [0002] Building Information Modeling (Building Information Modeling, referred to as BIM) technology is based on the relevant information data of the construction project as the basis of the model to establish the building model. BIM covers geometry, spatial relationships, Geographic Information System (GIS), the nature and quantity of various building components. BIM can be used to display the entire building life cycle, including the construction process and operation process, and it is very convenient to extract information about the materials in the building. Each part and each system in the building can be presented. [0003] In recent years, my country's transportation industry has developed rapidly, and highways have entered a stage of leapfrog development. W...
