Example Embodiment

[0048] The present invention will be described below with reference to the drawings.

[0049] The invention is an online water quality monitoring method based on computer vision to monitor fish vital signs, which mainly includes the steps of image acquisition, foreground detection, and medaka vital signs detection.

[0050] Such as figure 1 versus figure 2 As shown, the image acquisition step adopts a video acquisition device based on a monocular camera, and selects the most reasonable camera placement angle according to the distribution of the biological signs (gills, pectoral fins, and tail fins) of the medaka fish. Most traditional observation methods choose to place the camera directly above or on the side of the target container where the observation target is located. However, the traditional method is obviously difficult to satisfy the observation of the gill tissue of the medaka fish. After long-term repeated tests, the inventor found that placing the camera directly unde...

Abstract

The invention provides an on-line water quality monitoring method based on computer vision monitoring of vital signs of fins. A non-contact computer vision observation method is used for monitoring in real time the vital signs of medaka fish which is sensitive to change of water quality and serves a model organism, and the vital signs comprise a respiratory rate and a respiratory amplitude value which serve as physiological features, and the pectoral fin swinging frequency, the tail fin swinging frequency and the swinging amplitude value which serve as motion features. The monitoring of the water quality is realized according to the vital signs of the medaka fish. The method is reliable and easy to realize, has the advantages of instantaneity, reliability and the like, and can supply certain support and reference to development of biological type water quality monitoring and prewarning.

Description

technical field [0001] The invention relates to the fields of image processing, computer vision and pattern recognition, in particular to an online water quality monitoring method for vital signs of aquatic model organism medaka. Background technique [0002] With the rapid development of industry and agriculture, the problem of excessive discharge of pollutants has become increasingly serious, resulting in a significant decline in water quality and seriously affecting people's daily lives. For sustainable development, the prevention and control of water pollution has been raised to a level that is related to the survival of the nation. For the prevention and control of water pollution, the first thing that needs to be solved is the effective monitoring of water quality. Realizing timely and accurate water quality safety early warning has important practical significance for ensuring the safety of drinking water for the people and preventing the spread of diseases. [0003...
