Method and system for detecting working state of aerator

Abstract

An embodiment of the present invention provides a method and system for detecting the working state of an aerator. The method comprises a step of acquiring a corner point corresponding to a corner point in a target area in each frame and a reference frame according to an optical flow method for each frame in an aerator video to be detected, a step of acquiring an average displacement of the corresponding corner point in the frame and obtaining an exponentially weighted moving average displacement according to the average displacement, a step of inputting the average displacement of the corresponding corner point in the frame and the exponentially weighted moving average displacement into a preset support vector machine to obtain the working state of the aerator in the frame. According to the method and system for detecting the working state of an aerator provided by the embodiment of the present invention, the reference frame is used as a comparison object, the matched corner point isobtained by corner point detection and the optical flow method, the working state of the aerator is detected according to the average displacement of the matched corner point and the exponentially weighted moving average displacement by using the support vector machine, very obvious classification features can be extracted, the possibility of interference is little, and the accuracy of detecting the working state of the aerator can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, in particular to a method and system for detecting the working state of an aerator. Background technique [0002] Dissolved oxygen is an important water quality indicator, and it is also an important physical and chemical indicator of aquaculture. Dissolved oxygen that is too high or too low will affect the feeding and growth of farmed fish, and severe hypoxia will cause a large number of aquatic animals to die. Dissolved oxygen in water is a necessary condition for fish to survive. Fish live in water, and to carry out metabolism, the premise is that dissolved oxygen in water should be sufficient. Dissolved oxygen is not only closely related to the survival and growth of fish, but also can promote the appetite of fish, improve the utilization rate of feed, and accelerate the growth and development of fish. At the same time, too low dissolved oxygen in the aquaculture...
