Automatic monitoring device and method of micro agricultural insects based on machine vision

Abstract

The invention discloses an automatic monitoring device and an automatic monitoring method of micro agricultural insects based on a machine vision. The automatic monitoring device substantially consists of parts such as an automatic micro agricultural insect trap device, a camera and a computer. The automatic monitoring method substantially comprises the following steps: installing the automatic monitoring device; replacing a sticky insect-capturing plate; collecting a frame of image about the sticky insect-capturing plate; waiting for a while, collecting another frame of image about the sticky insect-capturing plate; applying a differential detection two the recently collected two frames of images about the sticky insect-capturing plate; and automatically counting and classifying the result of the differential detection; outputting the result, judging whether to stop monitoring, and judging whether to replace the sticky insect-capturing plate. The automatic monitoring device and the automatic monitoring method of the micro agricultural insects based on the machine vision can automatically trap the micro agricultural insects without the existence of the insect sex attractant and the high-voltage grid. The trapped insects can be automatically counted and classified by using the machine vision technology, so as to record the information that the number and the category of the trapped insects change with time.

Description

technical field [0001] The invention relates to the technical field of automatic monitoring of agricultural pests, in particular to a device and method for automatic monitoring of tiny agricultural pests based on machine vision. Background technique [0002] In my country's agricultural production, the microscopic agricultural pests that have a greater impact on yield and economic benefits are mainly Homoptera and Diptera pests, including but not limited to: aphids, planthoppers, whitefly, leafminer, fruit fly, etc. . At present, the field survey of these tiny agricultural pests still adopts the manual visual survey method, which is time-consuming and laborious, and the survey results are greatly affected by the investigators’ subjective influence. In addition, there is a shortage of grassroots plant protection personnel and the field survey task is heavy. This low-efficiency manual visual survey The law can no longer meet the requirements of modern agriculture. [0003] In...

Problems solved by technology

For example, patent 201410128410.4 discloses a pest trapping and counting device and counting system. The invention first uses insect attractants to trap pests, and then uses infrared counting technology and image counting technology to count pests. However, due to the lack of corresponding insect attractants agent, this invention can not trap tiny agricultural pests such as aphids, planthoppers, whitefly, leafminer, fruit fly, etc. At the same time, this invention also sets a high-voltage power grid in the trap, even if tiny agricultural pests fly to the trap by mistake It will also be electro-focused, so it cannot be counted accurately
