Unmanned plane flight path drawing method, device and system

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...
