Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] see figure 1 , a kind of unmanned aerial vehicle flight track drawing method of the present invention, the method comprises:

[0023] Step S10: planning the waypoint and flight path of the UAV flight. In this embodiment, the operator sets the flight waypoint and the flight path through the control terminal.

[0024] In this embodiment, step S10 includes:

[0025] Step S20: setting the flight path of the drone on the electronic map;

[0026] Step S21: selecting a waypoint for the drone to fly on the flight path;

[0027] Step S22: Calculate the distance from each waypoint to the take-off...

Abstract

The invention provides an unmanned plane flight path drawing method, device and system. The method comprises the steps of: planning a flight destination and a flight path of an unmanned plane; receiving a position signal returned in the flight process of the unmanned plane every a set time interval, and drawing the flight path of the unmanned plane on an electronic map according to the position signals; and if failing to receive the position signals in the set time interval, then setting the position, corresponding to the last received position signal, on the electronic map as a starting point of a virtual path, starting drawing the virtual path, using the flight speed of the unmanned plane at the time of the last received position signal as an analog flight speed of the unmanned plane, determining the flight direction at the present position of the unmanned plane according to the direction of the destination, determining the next arrived position of the unmanned plane after the set time interval, and drawing the virtual path of the unmanned plane on the electronic map according to the next position. By adopting the unmanned plane flight path drawing method, a user is enabled to estimate the position of the unmanned plane after the unmanned plane is lost, and the user is enabled to be still ready for unmanned plane recovery.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicles, and in particular relates to a method, a device and a system for drawing a flight trajectory of an unmanned aerial vehicle. Background technique [0002] Unmanned aircraft, referred to as "drone" for short, and "UAV" for English abbreviation, is an unmanned aircraft controlled by radio remote control equipment and its own program control device. In the prior art, the operator controls the flight of the drone through the control terminal. However, the distance between the drone and the operator is limited. If the distance exceeds this distance, the drone will lose signal with the operator, resulting in the inability to control the drone. machine. In order to solve this distance limitation, we select waypoints on the electronic map of the control terminal and let the UAV automatically fly to these waypoints, so that the UAV can fly a long distance. However, since the UAV will not return th...
