Implementation method of ground station three-dimensional navigation map of small unmanned air vehicle

Abstract

The invention discloses a design method of a ground station three-dimensional navigation map of a small unmanned air vehicle. The method comprises the steps of Google Earth application program interface (API)-based map data acquisition, geographical coordinate conversion and navigation function implementation. Network map data of a flight area can be stored into a local two-dimensional array by a Google Earth API; map data is drawn into a ground station navigation map area by a three-dimensional drawing interface, so that a three-dimensional map can be formed; flight destinations of the unmanned air vehicle are inquired in local map data and are drawn in the three-dimensional map, so that the three-dimensional map navigation function can be realized. By virtue of the method, the three-dimensional navigation map with low cost can be provided for a ground station of the small unmanned air vehicle, the map display intuition is improved, and the flight safety of the unmanned air vehicle can be improved under complex terrain conditions.

Description

technical field [0001] The invention relates to a three-dimensional navigation map design method, which is mainly applied to the field of small unmanned aerial vehicle ground stations. Background technique [0002] UAV-piloted aircraft, referred to as UAV, is a power-driven, radio-controlled or autonomously controlled unmanned aircraft. Among them, small UAVs generally refer to UAVs with a take-off weight of less than 10KG. Due to their small size, light weight, flexible operation, and many characteristics such as mission platforms, small UAVs have been used in military reconnaissance, geological mapping, and disaster situations in recent years. Monitoring and aerial photography are playing more and more roles, showing great application prospects. The UAV ground station is the control center of the UAV. It mainly completes the functions of real-time collection and analysis of telemetry data, sending remote control instructions, and displaying flight status. It is the core p...

Problems solved by technology

[0005] The present invention aims to provide a method for designing a three-dimensional navigation map for a ground station of a small unmanned aerial vehicle. The technical problem to be solved is to first obtain the network map data of the three-dimensional navigation map, and then draw a local three-dimensional navigation map on the ground station according to the map data. Under the premise of not increasing the development cost of the ground station, improve the intuitiveness of the navigation map display of the ground station and the flight safety of the UAV under complex terrain conditions
