Abstract

The invention provides an unmanned aerial vehicle aerial photography modeling method based on a BIM technology, and the method comprises the following specific implementation steps: 1, carrying out the aerial photography of an unmanned aerial vehicle, collecting the related information of an on-site construction drawing, and obtaining the landform and on-site conditions of a project based on a motion recovery structure algorithm and scale invariant feature conversion; 2, completing later-stage GIS data processing of the aerial survey by adopting ContextCapture; 3, a local area network is built, and GIS data are processed in a cluster mode; Step 4, importing the model raw material data into revit software to generate a three-dimensional model; and 5, arranging on-site temporary constructionand planning construction routes and specific construction schemes by using the geomorphic model generated by revit software in combination with the design drawing. Aerial photography modeling of theunmanned aerial vehicle is well utilized based on the BIM technology, rapid and accurate modeling is achieved, the modeling mode is more convenient, the model culvert surface is wider, daily aerial photography of the unmanned aerial vehicle is achieved, the modeling progress is dynamically followed, and construction is guided.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a BIM technology-based UAV aerial photography modeling method. Background technique [0002] With the development of modern technology, more and more technologies are applied in the field of construction engineering, including drone aerial photography and BIM technology; [0003] UAVs play the role of aerial vehicles and are one of the efficient tools that can obtain real-world data; with high-definition cameras or lidars, they can efficiently obtain spatial data of the real environment, and then correct and process them through algorithms to finally obtain point cloud data or 3D model, which stands for reality modeling technology. [0004] As a new tool in architecture, engineering and civil engineering, BIM can reproduce the design ideas in the form of three-dimensional models through software, and then add a large number of design parameters and project-relat...
