Method and system for detecting working state of aerator

Abstract

Embodiments of the present invention provide a method and system for detecting the working state of an aerator. Wherein, the method includes: for each frame in the aerator video to be detected, obtain the corner points in the frame corresponding to the corner points in the target area in the reference frame according to the optical flow method; obtain the corresponding corner points in the frame The average displacement of the point, and obtain the exponentially weighted moving average displacement according to the average displacement; input the average displacement and exponentially weighted moving average displacement of the corresponding corner points in the frame into the preset support vector machine, and obtain the work of the aerator in the frame state. The method and system for detecting the working state of the aerator provided by the embodiments of the present invention take the reference frame as the comparison object, obtain the matching corner points through corner point detection and the optical flow method, and use the support vector machine according to the average displacement of the matching corner points Using the exponential weighted average displacement to detect the working state of the aerator can extract very obvious classification features, and is not easily disturbed, and can improve the accuracy of detecting the working state of the aerator.

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...
