Water toxicity biological monitor and monitoring method

Abstract

The invention belongs to the technical field of water quality monitoring, and provides a water quality toxicity biological monitor and monitoring method. The monitor comprises an acquisition unit, a pretreatment unit, a coordinate extraction unit, an action track determination unit and a head and tail swing frequency determination unit. The monitoring method comprises the following steps: acquiring images of a tested fish in unit time; preprocessing the acquired images of the tested fish at different angles; extracting center position coordinates, head position coordinates and tail position coordinates of different individuals in the preprocessed images of the tested fish at the different angles; according to the center position coordinates of different individuals in the preprocessed images of the tested fish at the different angles, determining action tracks of the different individuals; and determining the position coordinate changes of the heads and the tails of different individuals in the preprocessed images of the tested fish at the different angles. According to the water quality toxicity biological monitor and monitoring method, the accuracy is high, and the activity of the whole fish or fish individuals can be mastered conveniently in real time.

Description

technical field [0001] The invention relates to the technical field of water quality monitoring, in particular to a water quality toxicity biological monitor and a monitoring method. Background technique [0002] The water quality biological toxicity detector detects the toxicity of pollutants in water by using fish, fleas or other aquatic organisms as detection organisms and observing the activity status of fish, fleas or other aquatic organisms. [0003] When the traditional water quality biotoxicity detector detects the activity of fish, it detects the activity of fish by detecting the change of the central position of the fish individual. The situation of the position, therefore, will produce the error of movement when detecting the activity of the fish. Contents of the invention [0004] Aiming at the defects in the prior art, the present invention provides a water quality toxicity biological monitor and monitoring method, which have high accuracy and are convenient ...
