Problems solved by technology

[0002] Airport clearance models are usually built using images such as satellite remote sensing images. However, due to the long revisit cycle of satellite remote sensing and untimely emergency response, the update speed of the image data for the construction model is slow; The accuracy of the test will bring hidden dangers to the safety of airport operations and flight safety in the terminal area.

Abstract

The invention relates to an airport clearance three-dimensional model construction method and device based on unmanned aerial vehicle shooting. The method comprises the steps that stereopair data collected by an unmanned aerial vehicle are acquired; obtaining an airport clearance area digital surface model according to the stereopair data; and performing superposition processing on a preset airport clearance limiting surface three-dimensional model and the airport clearance area digital surface model to obtain an airport clearance three-dimensional model. According to the embodiment of the invention, high-resolution image acquisition can be realized through the unmanned aerial vehicle, the updating time is short, the operation is easy, and the defects of low updating speed of traditional three-dimensional relative image data and poor data quality caused by cloud shielding are overcome; meanwhile, the three-dimensional model of the airport clearance limiting surface and the digital surface model of the airport clearance area are superposed, so that an ultrahigh building and a building with potential danger can be accurately identified, accurate data support is provided for an airport operation management department, and the airport operation safety and the terminal area flight safety are guaranteed.

Description

technical field [0001] The present disclosure relates to the field of aviation technology, in particular to a method and device for constructing a three-dimensional model of airport clearance based on unmanned aerial vehicles. Background technique [0002] Airport clearance models are usually built using images such as satellite remote sensing images. However, due to the long revisit cycle of satellite remote sensing and untimely emergency response, the update speed of the image data for the construction model is slow; The accuracy will bring hidden dangers to the safety of airport operations and flight safety in the terminal area. Contents of the invention [0003] In view of this, the present disclosure proposes a method and device for constructing a 3D model of airport clearance from aerial photography by a UAV. [0004] According to an aspect of the present disclosure, a method for constructing a 3D model of airport clearance based on drone photography is provided, in...
