Abstract

The invention discloses a three-dimensional real scene modeling method based on aerial survey of an unmanned aerial vehicle. The three-dimensional live-action modeling method based on aerial survey ofthe unmanned aerial vehicle comprises the following steps that 1, three-dimensional live-action modeling is carried out, aerial survey data are obtained through aerial survey of an unmanned aerial vehicle, image analysis is conducted through an aerial triangular analysis method, a series of two-dimensional aerial images are converted into three-dimensional dense point clouds of the to-be-measuredconstructional engineering, then data post-processing is conducted, a digital line drawing map and a digital surface model of the to-be-measured constructional engineering are obtained, and a live-action three-dimensional model is obtained; performing live-action patrol of the to-be-tested constructional engineering based on the live-action three-dimensional model and real surface point cloud toobtain construction execution data of the to-be-tested constructional engineering; and based on comparison of the three-dimensional planning design and construction execution data of the to-be-testedconstructional engineering, researching and issuing a construction scheduling instruction, and checking and correcting the execution effect of the scheduling instruction. The three-dimensional real scene modeling method based on aerial survey of the unmanned aerial vehicle is high in efficiency and low in cost.

Description

technical field [0001] The present invention relates to the technical field of architectural design, and more specifically, the present invention relates to a three-dimensional real-scene modeling method based on unmanned aerial vehicle aerial survey. Background technique [0002] Three-dimensional GIS (Geographic Information System, Geographic Information System) is one of the main symbolic contents of GIS technology today and even in the future. Provides more effective auxiliary decision support. For the construction industry and surveying and mapping, scalable 3D models are essential. [0003] In the field of traditional engineering construction, when performing 3D modeling of buildings, manual measurement is usually used, and then manual sketching and model rendering are performed on the 3D modeling software. The modeling time sequence is long, the process is complicated, and manual measurement and drawing It is easy to cause serious problems such as insufficient preci...
