Pesticide spraying accurate control method and device based on instance division

Abstract

The invention discloses a pesticide spraying accurate control method based on instance division, relates to agricultural pesticide spraying, and solves the technical problems of poor pesticide spraying accuracy and liability for damage to a camera of an existing identification method. The control method comprises the steps of: acquiring images of a to-be-identified target under the conditions of different angles, resolutions and definitions and using the acquired images as training images; carrying out instance division training on the training images and establishing a target identification model of the to-be-identified target; acquiring a video image of a pesticide application operation environment in a shooting mode that spray nozzles are in the front and the camera is at the back, inputting the video image into the target identification model, and carrying out instance division on the target in the video image, which is partially shielded by the spray nozzles, by the target identification model so as to obtain a spray target range; adopting the spray nozzles controlled in groups; and controlling the spray nozzles corresponding to the spraying target range to carry out the quantitative spraying operation. The invention further discloses a pesticide spraying accurate control device based on instance division. According to the invention, pesticide spraying accuracy can be improved, and damage to the camera can be prevented.

Description

technical field [0001] The present invention relates to agricultural spraying, more specifically, it relates to a method and device for precise control of spraying based on instance segmentation. Background technique [0002] Vision-based water and fertilizer spraying technology has been applied to agricultural production. In the traditional identification method, in order to avoid the situation where the target is blocked as much as possible, the camera is placed in front or on the side of the nozzle. Although the captured image has little interference, the spraying process will cause greater interference to the use of the camera. Poor, the camera is also easily damaged. Contents of the invention [0003] The technical problem to be solved by the present invention is to address the above-mentioned deficiencies in the prior art. The first purpose of the present invention is to provide a precision spraying control method based on instance segmentation that can improve spra...
