Unmanned aerial vehicle night plant protection method based on multi-view vision

Abstract

The invention relates to an unmanned aerial vehicle night plant protection operation method based on multi-view vision, and belongs to the technical field of aviation systems. The method comprises thefollowing steps of arranging a plurality of binocular vision sub-platforms around a farmland to be subjected to plant protection to form a multi-view vision platform; carrying out parameter calibration on the binocular vision sub-platforms, and then calibrating the position relation between the binocular vision sub-platforms; calculating the initial position of the plant protection unmanned aerial vehicle platform relative to the farmland through a multi-view vision system; planning a flight path of the plant protection unmanned aerial vehicle by using a ground control platform; starting plant protection work, in the operation process, enabling the multi-view vision platform to capture infrared feature identification points on the plant protection unmanned aerial vehicle platform, calculate the position of the plant protection unmanned aerial vehicle relative to a farmland in real time, and feed back position information to an autopilot and a ground control platform of the plant protection unmanned aerial vehicle, which is used for correcting the route of the unmanned aerial vehicle in the plant protection operation process in real time. A pesticide spraying platform is carried onthe unmanned aerial vehicle platform and is an executing mechanism for plant protection operation of the unmanned aerial vehicle.

Description

technical field [0001] The invention belongs to the technical field of aviation systems, and in particular relates to a night plant protection method for drones based on multi-eye vision. Background technique [0002] my country is a big country in agricultural production and consumption of agricultural products. my country has 2.025 billion mu of basic arable land. These arable lands require a large number of agricultural plant protection operations every year, especially in seasons when pests and diseases break out. However, the traditional artificial plant protection methods require more human resources and low plant protection efficiency, which affects the normal agricultural production in our country and restricts the development of our country's agriculture. [0003] With the continuous advancement of science and technology and the continuous advancement of agricultural modernization, efficient, safe and precise modern agriculture is favored by governments at all levels...
