Embodiment Construction

[0022] like figure 1 As shown, the device is composed of a printer 1, an on-site host computer 2, an image acquisition card 3, a multi-channel video selector 4, cameras T1, T2..., Tn and other cameras connected in sequence.

[0023] according to figure 2 In the process, firstly, the computer 2 starts to run, initializes the variables, takes a certain camera Ti to capture the real-time picture of the fish pond Ci, and reads an image into the memory of the computer 2 through the image acquisition card 3 . Then it is converted into a grayscale image, and in order to suppress interference and eliminate noise, a median filter is performed. The result of the processing is as image 3 shown.

[0024] Then carry out the processing of binarization of the grayscale image. The key to image binarization is to select a good segmentation threshold to separate the diseased fish from the background. According to the statistical data obtained from many experiments, when the threshold is 2...

Abstract

The invention relates to computer digital image process technology in aquiculture industry. The device is made up with printer, upper computer on the spot, image collection card, multi-channel video selector and multiple pick-up heads. Use multi-channel video selector to select some pick-up to shoot rearing pond's real-time picture; the picture is sent to video images collection card; the card converts analog image signal to digital image signal that can be processed by computer; process, identification and alert is made by computer according to preset programs; the processed result is memorized to database in computer; original image is binarized to distinguish white belly of sick fish from background color, then statistic quantity and size of the white zone part, judge is made according to area of white zone to take measures. Adopting the invention, fishes' disease can be early diagnosed and predicted; fishes can be prevented from damage and a new method for aquiculture fishes' disease diagnosis.

Description

technical field [0001] The invention relates to computer digital graphic processing technology in the field of aquaculture, in particular to an automatic diagnosis method and device for fish diseases using image processing. Background technique [0002] In recent years, with the development of the economy and the improvement of people's living standards, the demand for aquatic products has also increased. Therefore, factory aquaculture has become the main production mode of aquaculture. However, in industrial aquaculture farms, microorganisms tend to multiply in large numbers, and there are more and more diseases, and the abuse of fish medicines is more likely to cause a large number of fish deaths in a short period of time. Therefore, it has become an important task in the aquaculture industry to find out the diseased or dead fish in the aquaculture pond early so as to take corresponding remedial measures. [0003] After searching domestic related databases, there have bee...
