Problems solved by technology

[0005] Embodiments of the present invention provide a spraying method of drones and drones, which are used to solve the problem of not taking into account when planning navigation routes when drones are used to spray pesticides or fertilizers on farmland in non-plain areas in the prior art. To the actual terrain of the area to be sprayed, the planned navigation route is not suitable for the actual terrain of the area to be sprayed, which leads to the problem of uneven spraying of pesticides in the area to be sprayed

Embodiment Construction

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0035] Additionally, the terms "system" and "network" are often used herein interchangeably. The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations. In addition, the character " / " in this article generally indicates that the contextual ob...

Abstract

The invention, which relates to the technical field of the unmanned plane, discloses a spraying method of an unmanned plane and an unmanned plane. With the method and the unmanned plane, liquid pesticide can be sprayed uniformly in farmland at a target working area. According to the specific scheme, the method comprises: obtaining an image of a target working area and carrying out image segmentation to obtain a coordinate of an edge pixel of an image corresponding to a to-be-sprayed area; obtaining an actual flight height of the unmanned plane relative to the ground when collecting the image corresponding to the to-be-sprayed area by the unmanned plane at a constant height relative to a horizontal plane; according to the coordinate of the edge pixel, a shooting focus, and the actual flight height, calculating an actual navigation coordinate corresponding to the edge point of the to-be-sprayed area; and planning a navigation route based on the actual navigation coordinate and spraying liquid pesticide on operated objects at the to-be-sprayed area according to the navigation route. The method can be applied to the liquid pesticide spraying process by the unmanned plane.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a spraying method of an unmanned aerial vehicle and an unmanned aerial vehicle. Background technique [0002] Unmanned aircraft, referred to as UAV (English: UnmannedAerialVehicle, referred to as: UAV), is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device. UAVs are widely used and are often used in urban management, agriculture, geology, meteorology, electricity, emergency rescue, video shooting and other industries. For example, drones can be used in agriculture to spray pesticides (or fertilizers) on agricultural products. [0003] Specifically, a spraying device for spraying pesticides can be installed on the drone, and then the navigation route is planned for the drone according to the position and size of the area to be sprayed (farmland that needs to be sprayed with pesticides), and then the unmann...
