Description

Technical Field

[0001] The utility model relates to the technical field of machine vision, in particular to a single-sided multi-structure graphic plate. Background Art

[0002] As we all know, artificial intelligence is developing rapidly, and machine vision has also become popular. Machine vision mainly uses machines to replace human eyes for measurement and judgment. The machine vision imaging system captures key information such as pixels, color, and brightness provided by the target, and then converts it into a digital signal, obtains the target features through the image system, and controls the operation of the equipment through the judgment results. In the visual system, the camera is an extremely important core component. When the lens is distorted, it needs to be corrected. In the past, the corrected graphic plates were mostly single-sided and single-structure materials (such as: only including glass substrates), and the color and brightness of the graphic plates affected the camera capture and the final effect.
