Problems solved by technology

[0002] UAVs are widely used in various fields, such as map surveying, geological survey, disaster monitoring, UAV inspection, air traffic control, etc. Most of the existing UAV autonomous navigation functions are only suitable for navigation in open environments. However, in terms of autonomous navigation of UAVs for building complexes, most UAVs at home and abroad do not have corresponding navigation methods.

Abstract

The invention discloses a building group orientated unmanned aerial vehicle autonomous navigation method. The building group orientated unmanned aerial vehicle autonomous navigation method comprises the following steps: obtaining a topographical stereoscopic point cloud through three-dimensional laser scanning, and then generating a three-dimensional building group model through a modeling platform; collecting reference images; loading the three-dimensional building group model by using a mobile phone, a palm computer or a notebook computer, and calibrating a navigation destination on the three-dimensional building group model through a touch screen or a mouse; determining the flight path of the navigation destination; and determining a navigation method to arrive at the destination. Through the navigation manner, autonomous navigation can be realized more accurately, the method is not limited by ground buildings, and the application range of an unmanned aerial vehicle is enlarged.

Description

technical field [0001] The invention relates to an autonomous navigation method of an unmanned aerial vehicle, in particular to an autonomous navigation method of an unmanned aerial vehicle facing building groups. Background technique [0002] UAVs are widely used in various fields, such as map surveying, geological survey, disaster monitoring, UAV inspection, air traffic control, etc. Most of the existing UAV autonomous navigation functions are only suitable for navigation in open environments. However, in terms of autonomous navigation of UAVs for buildings, most domestic and foreign UAVs do not have corresponding navigation methods. Contents of the invention [0003] In order to solve the problem that most of the UAVs do not have corresponding navigation methods for building groups, the present invention provides a method for autonomous navigation of UAVs for building groups, including the following steps: [0004] S01 navigation preparation, the navigation preparation...
