Abstract

Abstract

Aiming at the difficulty in detecting the amount of silicone oil injection caused by the small gray difference between the neutral transparent refill and the colorless silicone oil, a new method and system for detecting the injection amount of colorless silicone oil based on machine vision was proposed and designed. An image acquisition unit and an external light source control unit were the main hardware part of the system. By adjusting the illumination angle of the external light source, the enhancement of the gray difference in the colorless silicone oil area can be realized. In the part of software and algorithm, a gray region histogram algorithm was used to select the corresponding region of interest (ROI) and parameters on the constructed human interaction interface, and the length detection results were displayed in real time. The experimental results show that the system can accurately detect the continuous length of silicone oil, the system has good real-time performance and stability, high accuracy, and has a certain value of promotion and application.
