The invention relates to the technical field of computer vision, in particular to an air tightness detection light source adjusting method and system based on computer vision. The method comprises thefollowing steps: collecting an image of a detection pool, and obtaining a water body region of interest of the denoised image; carrying out definition evaluation on the region of interest to obtain water body definition; acquiring a water body shaking degree, and dividing the water body shaking degree into shaking grades according to the water body shaking degree; correcting the current water body definition by using a corresponding correction model according to the current shaking level; performing image brightness extraction on the image to obtain an image brightness analysis value of the image; and obtaining the multiplying power of light source adjustment according to the corrected water body definition and the image brightness analysis value. According to the embodiment of the invention, the bubble characteristics are more prominent, the air tightness of the equipment is more accurately detected, and the air tightness detection precision is improved.
Description
technical field [0001] The invention relates to the technical field of computer vision, in particular to a method and system for adjusting a light source for air tightness detection based on computer vision. Background technique [0002] The lighting system is one of the most critical parts of the machine vision system. The machine vision light source directly affects the quality of the image, and then affects the performance of the system. The image quality requirement is high in the air tightness testing process of the equipment. In order to obtain high-quality images and make the bubble features more obvious, it is necessary to adjust the light source of the air tightness testing system of the equipment to ensure the stability of the image. [0003] In practice, the inventor finds that the above-mentioned prior art has the following defects: [0004] During the air tightness testing process of the equipment, due to the influence of the light intensity of the light source...
