[0003] In the prior art, when the airtightness test is performed on the equipment, if the water body in the detection pool sloshes, the air bubbles on the wall and bottom of the pool will be shaken up, that is, when the water body sloshes, the air bubbles on the wall and bottom of the pool are at In the state of motion, the number of bubbles increases, and the bubbles fluctuate in a large area, which will eventually affect the air tightness test results of the equipment. It is difficult to locate the leak location with the naked eye, resulting in inaccurate test results

Embodiment Construction
[0073] In order to further explain the technical means and functional effects adopted by the present invention to achieve the intended purpose of the invention, in conjunction with the accompanying drawings and preferred embodiments, a water body sloshing detection and analysis method and system based on image processing proposed according to the present invention, The details are as follows.
[0074] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention.
[0075] It needs to be explained here that when detecting and analyzing the state of the water body in the detection pool, it is necessary to ensure that the external environmental factors are relatively ideal, the temperature of the detection pool is at an appropriate temperature, and the external light intensity is fixed, etc., so as to avoid external factors affecting the extraction of bubble fea...

The invention relates to the technical field of image processing, in particular to a method and system for detecting and analyzing water body sloshing based on image processing. The method includes: acquiring multiple frames of initial images of the water body; removing the mirror image in the initial image of the water body to obtain an actual image of the water body; performing grayscale conversion on the actual image of the water body, and converting the The gray value of each pixel in the actual image of the water body is assigned the gray value corresponding to the gray level interval to obtain the water body target image; the difference between two adjacent frames of the water body target image is calculated to obtain the bubble image; Obtaining the number of bubbles and the degree of dispersion of the bubbles; inputting the number of bubbles and the degree of dispersion of the bubbles into a preset water body sloshing degree detection model to obtain the degree of water body sloshing. The invention can simply and quickly identify the water body sloshing phenomenon in the process of testing the air tightness of the equipment, so as to ensure that subsequent workers can accurately detect the air tightness of the equipment.
Description
[0001] The invention relates to the technical field of image processing, in particular to a method and system for detecting and analyzing water body sloshing based on image processing. Background technique [0002] Air tightness testing of pressure vessels and equipment is the most critical link in ensuring product quality. At present, the water immersion method is mostly used for the air tightness testing of equipment and containers. The water immersion air bubble detection method is to put the equipment into the detection pool, fill a certain amount of gas inside the equipment, and judge whether there is air leakage by visually observing whether there are bubbles. [0003] In the prior art, when the airtightness test is performed on the equipment, if the water body in the detection pool sloshes, the air bubbles on the wall and bottom of the pool will be shaken up, that is, when the water body sloshes, the air bubbles on the wall and bottom of the pool are at In the state of ...
