Embodiment 1

[0054] The present invention is described in detail below in conjunction with the accompanying drawings.

[0055] The present embodiment discloses a pesticide spraying UAV, comprising a fuselage 1, a propeller 2 connected to the fuselage 1, the fuselage is provided with a control device to control the operation of the UAV, the propeller 2 rotates to provide flight power to the UAV. The existing UAV body is connected to the medicine box, the medicine box is equipped with a liquid medicine, the bottom of the medicine box is equipped with a nozzle, the liquid is sprayed out of the nozzle due to gravity or the role of the pump, under the action of gravity, the liquid is easy to shake, and with the consumption of the liquid, the spraying is getting thinner and thinner, the uneven spraying before and after, if the pump is used, on the one hand, the weight of the drone is larger, consuming more electricity, at the same time, the pump is easy to block when spraying.

Embodiment 2

[0063] Example 2: The present embodiment discloses a pest detection method, the UAV according to the pest detection method is determined according to the pest detection method when spraying pesticides of the present invention, the UAV comprises a pest detection system, the pest detection system to achieve its function when performing the following method:

[0064] Obtain a video of the area to be detected, the video is obtained by the camera followed by the inorganic person;

[0065] Based on the previous frame image and the next frame image of the current frame image in the pest video, the residual area is obtained;

[0066] The residual region is fused with the current frame image to obtain a fusion of the current frame image;

[0067] The fusion of the current frame image is high-pass filtered to obtain a high-frequency current frame image;

[0068] The fusion of the current frame image is low-pass filtered to obtain a low-frequency current frame image;

[0069] The high-freque...

Abstract

The invention discloses a method for detecting pests of unmanned aerial vehicles, which belongs to the field of agricultural unmanned aerial vehicles. After the current frame image is pooled at least three times, the fifth output data is obtained; after the fifth output data is convolutionally processed at least twice, the sixth output data is obtained; and the sixth output data is pooled. After processing and one convolution processing, the seventh output data is obtained; the sixth output data and the seventh output data are fused to obtain the eighth output data; the eighth output data is pooled at least twice After processing and at least two convolution processes, the ninth output data is obtained; the ninth output data is classified to obtain the composite target area; if the distance between the current frame target area and the composite target area is less than a set threshold , to obtain the area where the pest is located.

Description

Technical field [0001] The present invention relates to the field of drone pest detection. Background [0002] Unmanned aerial vehicles, abbreviated as "unmanned aerial vehicles", are unmanned aircraft operated using radio-controlled equipment and self-contained program control devices. There is no cockpit on board, but it is equipped with autopilot, program control devices and other equipment. On the ground, on the ship or in the remote control station of the mother machine, the personnel track, locate, remote control, telemetry and digital transmission through radar and other equipment. It can take off like an ordinary aircraft under radio remote control or launch with a booster rocket, or it can be taken into the air by the mother aircraft and launched into the air. When recycling, it can be automatically landed in the same way as the landing process of ordinary aircraft, or it can be recovered by remote control with a parachute or a net. Can be used repeatedly. Widely used in...
