AI Technical Summary

Technical Problem

Traditional marine ranch environmental monitoring methods are time-consuming and labor-intensive, making it difficult to achieve real-time monitoring. Traditional equipment has limited coverage and cannot fully reflect the dynamics of the marine ranch environment, especially in the face of sudden environmental events, making it difficult to meet the needs of rapid decision-making.

Method used

Images of the marine ranch water surface are collected by drones or fixed platforms equipped with multispectral cameras. By combining image preprocessing and algae spectral index calculation algorithms, algae-covered areas are distinguished from non-algae-covered areas, generating binarized images and calculating algae coverage. Turbidity spectral index algorithms are used to calculate the turbidity of the water in non-algae-covered areas and generate early warning signals.

Benefits of technology

It enables precise quantification of algae coverage in marine ranches and accurate calculation of water turbidity, providing high-precision automated monitoring, reducing the cost and error of manual monitoring, improving the response speed of ecological environment management, and ensuring the ecological balance and sustainable development of marine ranches.

Abstract

The present application relates to the field of marine ranching environment monitoring, and more particularly to a marine ranching environment monitoring method. Collecting a marine ranching water surface image, obtaining original pixel values of each band; performing image preprocessing on the marine ranching water surface image to obtain normalized pixel values of each band; introducing an algae spectral index calculation algorithm based on the normalized pixel values of each band to generate an algae spectral index; based on the algae spectral index, marking algae regions and non-algae regions and generating a binary image; based on the binary image, calculating the algae coverage; based on the normalized pixel values of each band and the binary image, calculating the water turbidity of the non-algae region through a turbidity spectral index algorithm; comparing the algae coverage and the water turbidity with the algae coverage threshold and the water turbidity threshold respectively to generate an early warning signal. The problems of being difficult to accurately segment the algae region and being difficult to accurately reflect the water quality change of the non-algae region are solved.
