Water body shaking detection and analysis method and system based on image processing

Abstract

The invention relates to the technical field of image processing, in particular to a water body shaking detection and analysis method and system based on image processing. The method comprises the following steps of acquiring multiple frames of water body initial images, removing a mirror image in the initial water body image to obtain an actual water body image, graying the actual water body image, and endowing the gray value of each pixel point in the actual water body image with the gray value corresponding to the gray level interval according to a preset number of gray level intervals to obtain a water body target image, calculating a difference value between two adjacent frames of water body target images to obtain a bubble image, acquiring the number of bubbles and the dispersion degree of the bubbles, and inputting the bubble number and the bubble dispersion degree into a preset water body shaking degree detection model to obtain the water body shaking degree. According to the method, the water body shaking phenomenon in the equipment air tightness detection process can be simply and quickly identified, so 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 ...

[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
