Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0035] Such as figure 1 Shown, the automatic identification method of common vegetable insect on the yellow board of the present invention, its steps are:

[0036] (1) Image collection: Use an imaging device to collect images of vegetable insects on the yellow board. For example: use a digital camera to collect images of vegetable insects on a yellow board and send them to a computer.

[0037] (2) Image scaling: when a digital camera takes an image, due to the difference in the resolution of different models of the digital camera, the distance from the target when shooting will also lead to a difference in the resolution of the target after imaging, and the size of the insect is one of the methods for judging the insect species in the present invention. Important basis, therefore, the acquired images need to be scaled to achieve compar...

Abstract

The invention discloses an automatic identification method for common vegetable insects on a yellow board, which comprises the following steps: (1) image acquisition: acquiring an image of a vegetable insect on the yellow board by using an imaging device; (2) carrying out zooming, rotating, shearing and target image separation processing on the image of the vegetable insect on the yellow board; (3) calculating the area, rectangularity and elongation of the image of the vegetable insect on the yellow board; (4) separating a deep-color part of the image of the insect from the background; (5) calculating the area, rectangularity and deep-color part contour projection quantity of the deep-color part image of the image of the insect; and (6) according to the shape characteristics of different kinds of insects and the calculation results obtained in the steps (3) and (5), judging and displaying the name of the vegetable insect on the yellow board. The invention relates to a method capable of carrying out automatic identification on common vegetable insects on yellow boards. The method disclosed by the invention has the advantages that principle is simple, operation is easy, and identification can be automatically carried out on common vegetable insects on yellow boards.

Description

technical field [0001] The invention mainly relates to the field of insect identification methods in insect research, in particular to an automatic identification method for common vegetable insects on a yellow board. Background technique [0002] At present, yellow boards are more and more widely used in monitoring and controlling pests in vegetable greenhouses. Yellow boards attract many kinds of insects, including pests and natural enemies, so identifying the species of insects on yellow boards is a difficult problem that farmers often face. If the identification is wrong, the wrong control measures will be taken, which will lead to increased production costs, reduced production of agricultural products, and increased pesticide residues. [0003] One of the existing methods for judging the types of insects on the yellow board is: farmers will invite entomology-related technicians to identify the insects on the yellow board, but entomology-related technicians often live ...
