Abstract

The invention discloses a method and system for identifying aphids on yellow boards. The identification method comprises the steps of obtaining a yellow board image in a cotton field environment; performing adaptive threshold segmentation on the yellow board image twice, and determining a segmented yellow board image; determining a yellow board insect image according to the yellow board image andthe segmented yellow board image; obtaining insect types corresponding to the historical insect morphological characteristics; establishing an insect recognition network model by taking the historicalinsect morphological characteristics as input and taking the insect species as output; obtaining insect morphological characteristics of the yellow plate insect image; according to the insect morphological characteristics and an insect identification network model, identifying the insect species in the cotton large field, and determining aphids on the yellow plate; and according to the aphids onthe yellow plate, determining the quantity of the aphids in the cotton large field. According to the method and the system for identifying the aphids on the yellow board, the accuracy and the automation of aphid identification are improved.

Description

Technical field [0001] The invention relates to the field of image processing and pattern recognition, in particular to a method and system for identifying aphids on yellow boards. Background technique [0002] With the widespread cultivation of Bt cotton in Xinjiang, the damage of cotton bollworm to cotton takes the second place, and aphids and insect pests have gradually become an important factor restricting cotton yield and quality. Aphids have a short growth cycle and will reproduce in large numbers under high temperature and humidity conditions, and winged aphids will develop in unsuitable environments, which have a certain migratory nature. Moreover, there is a symbiosis of mutual benefit between aphids and ants, and ants also help wingless aphids to migrate. Aphid damage frequently occurs before and after the cotton flower. Aphids destroy the normal physiological state of cotton by feeding on the tender parts of cotton and affect the yield of cotton. Secondly, aphids s...
