Eriocheir sinensis quality estimation method based on unmanned aerial vehicle image processing

Abstract

The invention relates to an Eriocheir sinensis quality estimation method based on unmanned aerial vehicle image processing, and the method comprises the steps: firstly photographing Eriocheir sinensisimages on site through an unmanned aerial vehicle, and obtaining a plurality of high-quality Eriocheir sinensis images; secondly, preprocessing the image, including image correction, image noise reduction and target extraction; then, for the Eriocheir sinensis target area, using Wiener filtering to restore the target area, performing edge detection by using a Canny operator after the original image is updated, and extracting an Eriocheir sinensis feature area; and finally, calculating the pixel area of the feature region, establishing a quality estimation model for the quality and crustaceanarea of the Eriocheir sinensis by using multiple regression models, performing error analysis, and preferentially selecting the estimation model. Compared with a traditional eriocheir sinensis qualityestimation method, the eriocheir sinensis quality estimation method has the advantages that the stress reaction of eriocheir sinensis caused by the traditional method is effectively avoided, the estimation precision is high, and the high requirement of the modern aquaculture industry for Eriocheir sinensis cultivation refinement management can be met.

Description

technical field [0001] The invention relates to the technical field of computer applications, in particular to a method for estimating the quality of Chinese mitten crabs based on image processing of drones. Background technique [0002] Eriocheir sinensis is a unique aquatic product in my country, which has extremely high economic and medical value. In recent years, with the continuous development of aquaculture technology, the cultivation and intensification of Chinese mitten crab has been continuously improved. Accurate quality measurement can provide a scientific basis for farmers to regulate production and adjust the structure of the aquaculture industry. However, due to the particularity of Chinese mitten crab breeding, there are certain difficulties in quality estimation. [0003] The quality measurement of Chinese mitten crab is one of the important issues in the breeding process of Chinese mitten crab, which has a great influence on the feeding, grading capture and...
