Abstract

The invention relates to a building information model reconstruction method based on an oblique photogrammetry technology. An oblique photogrammetry technology and a three-dimensional model (BIM) roaming technology are adopted; image information in a three-dimensional building model is extracted along a certain path through a virtual camera of a three-dimensional model roaming technology and imported into corresponding real scene modeling software to be fused with an unmanned aerial vehicle oblique photography model result, and a virtual-real combined super-real scene building information model is generated. According to the invention, the oblique photogrammetry technology and the BIM modeling technology are deeply fused; on one hand, exterior facade reconstruction is carried out on a building information model through the oblique photogrammetry technology; the problems of geometric distortion, texture deformation and the like of an oblique photogrammetry technology on building modeling are solved, on one hand, the problems of low display efficiency and the like of a BIM model on a Web side are solved, and a brand-new thought is provided for display and application of the city-level BIM model.

Description

technical field [0001] The invention belongs to the technical field of building information model (BIM) real scene modeling, and specifically relates to a method for reconstructing a building information model based on oblique photogrammetry technology. It is an application technology suitable for BIM model modeling in large scenes. It can According to different needs, different strategies are adjusted, which is applicable to various scenarios of engineering construction implementation. Background technique [0002] Real-world modeling technology (also known as image-based three-dimensional reconstruction), mainly refers to UAV oblique photography real-world modeling technology, is a high-tech and practical technology developed in the field of surveying, mapping and remote sensing in recent years. One or more oblique photographic cameras collect images from different angles such as vertical and oblique at the same time, and perform analytic aerial triangulation, geometric co...
