Water quality monitoring method based on motion features of aquatic organism on picture

Abstract

The invention discloses a water quality monitoring method based on motion features of an aquatic organism on a picture. A carassius auratus is taken as an indicator organism, two cameras are employed to shoot a swimming picture sequence of the carassius auratus in a fish tank and mean motional velocity, steering number of times, average angle of turning, average inclination angle of the body and time for staying at the upper part of water in a unit time are solved according to the picture. Water quality is automatically judged according to the unusual changes of the five indicators so as to alarm when wastewater is detected to have an exceeding concentration. The method comprises the following steps of: firstly, employing two cameras to shoot the swimming picture sequence of the carassius auratus in the fish tank, detecting target area information of the carassius auratus on the pictures by applying an image segmentation technology in two picture sequences, solving positions and angles of the carassius auratus on the frame pictures according to the target area information, then solving the mean motional velocity, the steering number of times, the average angle of turning, the average inclination angle of the body and the time for staying at the upper part of water in a unit time according to the positions and angles information of the carassius auratus on all the frame images and judging pollution degree of the water according to the five indicators finally. The water quality monitoring method based on the motion features of an aquatic organism on a picture has the advantages of simplicity and easy implementation and solves the problems of the unicity of physical and chemical testing in water quality monitoring and the like.

Description

technical field [0001] The invention relates to a water quality monitoring method based on the motion characteristics of aquatic organisms in the image, which is used in the application fields of environmental monitoring, video motion analysis and agricultural habitat, and is used in water quality monitoring, atmospheric monitoring, environmental safety evaluation, biological information and sensing , energy saving and emission reduction, toxicity research, biological research and other aspects have practical application value. It belongs to the field of computer vision and environmental engineering. Background technique [0002] At present, a series of research work has been carried out on water quality monitoring at home and abroad. In the process of water quality evaluation, physical and chemical methods are usually used for routine water environment index detection. The use of biological detection can detect the synergy of multiple pollutants, which has great advantages...
