[0005] When testing the airtightness of the workpiece, the water needs to be changed when the water reaches a certain turbidity. If the rate of water change is not appropriate, the turbidity of the water will still be high after changing the water.

The invention relates to the technical field of artificial intelligence, and in particular relates to a water change rate water body steady state detection system and method based on visual perception. The system comprises a water change detection module used for performing water change rate detection once every time a predetermined number of frames of water body images are collected after water change is started, obtaining a second average turbidity of the water body in each frame of water body image, obtaining a turbidity change trend of the water body image based on height distribution, andobtaining a preliminary score of the current water change rate according to a preliminary water change scoring model constructed by weighted averaging of the turbidity change trend; a shaking detection module is used for acquiring the shaking degree of bubbles in the images; and a water change scoring module is used for scoring the current water change rate according to the water change scoring model constructed by the positive correlation relationship between the preliminary score and the water change scoring model and the negative correlation relationship between the shaking degree of the bubbles and the water change scoring model, and adjusting the water change rate when the score is smaller than a preset scoring threshold. According to the system, the accuracy of evaluating the waterchange rate is improved.
Description
technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to a visual perception-based system and method for detecting the water body steady state of the water exchange rate. Background technique [0002] During the air tightness test, the water will gradually become turbid with the increase of the number of workpieces. Generally, when the turbidity reaches the threshold, it is necessary to change the water. Contaminated, cloudy water flows out of the water pipe. In the process of changing water, as long as the rate of inflow or pumping is appropriate, the water body will become clear from top to bottom, but if the rate is not appropriate, the water will be disturbed by inflow and pumping, such as water intake and pumping The current of the water affects the steady state of the water, and the impurities in the water float up, which makes the water turbid instead. [0003] When changing the water, the air bubbles emerging ...
