Embodiment 1

[0042] A method for route planning of an unmanned aerial vehicle according to the present invention comprises the following steps:

[0043] Step S100: Obtain flight area and route parameters.

[0044] In one embodiment, the operator can operate on the satellite map through the display interface of the UAV ground control station. Preferably, the operator can manually select at least 3 waypoints on the satellite map, and connect several waypoints end to end. Together, a convex polygonal area is formed, which serves as the flight area of ​​the drone. It should be noted that in this embodiment, selecting several waypoints and connecting the waypoints end to end to form a flight area is a common method for generating a flight area. Those skilled in the art can design and select a flight area in other ways, such as in Directly circle the area on the satellite map as the flight area.

[0045] Secondly, the operator edits the basic route parameters of the UAV in the flight area thro...

Embodiment 2

[0074] Such as figure 2 and image 3 As shown, it is another way of generating the flight route in the flight area in Embodiment 1.

[0075] The operator adjusts the direction of the flight path generated by the UAV according to the flight environment such as wind speed direction or electromagnetic field direction, which is used to improve the flight stability and endurance of the UAV.

[0076] Specifically, the flight area is a triangle ABC, and the triangle ABC forms a minimum circumscribed rectangle ADEF through a similar algorithm based on rotation jamming.

[0077] The angle α formed by the flight direction of the drone and the horizontal axis is used as the deflection angle α of the flight of the drone, and the flight path formed by the drone in the rectangle ADEF according to the deflection angle α. In the rectangle ADEF, draw a number of straight lines with an angle α with the horizontal axis according to the distance between the routes, and intersect the sides of t...

Embodiment 3

[0081] Such as Figure 4 As shown, it is a schematic diagram of a flight route of another flight area described in the present invention.

[0082] The operator selects 6 waypoints that are not on the same straight line for the satellite map through the display interface of the ground control station, and every 3 waypoints are not on the same straight line, the 6 waypoints form a hexagonal ABCDEF, and the six waypoints are not on the same straight line. The polygon ABCDEF obtains the minimum circumscribed rectangle JKSR based on the similarity algorithm of rotation jamming, and the two long sides JK and RS of the rectangle overlap with the two sides AB and ED of the hexagon. The calculation module of the UAV calculates the route spacing according to the flight height edited by the operator and the degree of lateral overlap. The rectangular point J is used as the starting point of the route trajectory, and JK is a part of the route trajectory. Line segments MN and OP, etc., the...

Abstract

The invention discloses a method for route planning of an unmanned aerial vehicle. The method includes the steps that a flight area and air route parameters are obtained; according to air route parameters, the air route spacing between every adjacent air routes is calculated according to a first preset rule; and according to the air route spacing, a flight air route is generated in the flight area. Based on the flight area and the air route parameters determined by an operator, according to the first preset rule, the air route spacing between every adjacent air routes is calculated and then the flight air route is automatically generated, thus the defect of large errors in manually planned air routes is overcome, the situation that accidents are prone to occurring on some operators due tolacking of the actual aerial photography experience is also avoided, and the efficiency and accuracy of unmanned aerial vehicle aerial photography are further improved.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle flight, and in particular relates to a method and device for route planning of an unmanned aerial vehicle. Background technique [0002] UAV is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device. With the rapid development of UAV technology, it has gradually expanded from the initial military field to the field of life consumption, and is often used in plant protection, street view, etc. Shooting, power inspection, environmental protection, post-disaster rescue, etc., have brought great convenience to daily life. [0003] At present, due to the large number of brands and models of drones, there are differences in their operating specifications. For beginners or operators with less experience, they lack rich practical experience in corresponding drones, and there are hidden dangers of improper operation. Damage to flying equi...
