Machine-vision-based laser deinsectization device and method

Abstract

The invention discloses a machine-vision-based laser deinsectization device and method. The machine-vision-based laser deinsectization device is composed of a high ground gap operating platform, a laser transmitter movement mechanism, a laser transmitter and a machine vision system; the machine vision system and the laser transmitter movement mechanism are mounted below a car frame of the high ground gap operating platform; and the laser transmitter is mounted on the laser transmitter movement mechanism. During work, a crop image below the car frame is acquired by the machine vision system andis analyzed, insects on crops are recognized and located, and then, the laser transmitter is sequentially moved to a position right above the insects by the laser transmitter movement mechanism to vertically and downwards transmit a laser beam one by one so as to kill the insects. Compared with the prior art, the machine-vision-based laser deinsectization device has the advantages of no pollution, high deinsectization efficiency and high automation degree due to vertical and downward machine vision image recognition and location as well as killing of insects on the crops in a laser striking way.

Description

technical field [0001] The invention relates to the technical field of plant protection physical insect extermination, in particular to a machine vision-based laser insect extermination device and method. Background technique [0002] The production and consumption of vegetables in my country rank first in the world, and the planting area and output of vegetables account for about 40% and 50% of the world's total respectively. With the expansion of the sown area of ​​crops year by year, the difficulty of pest control is increasing. The overall use of pesticides in my country is on the rise, the average utilization rate of pesticides is only 35%, and about 70% of the farmland is polluted to varying degrees. Most of the pesticides are lost through runoff and drift, polluting the soil and water environment, and affecting the safety of the farmland ecological environment. [0003] There is an urgent need for a control method that can kill insects and is harmless. At present, t...
