Embodiment Construction

[0049] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0050] It should be noted that when an element is referred to as being “fastened to” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0051] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations or positio...

Abstract

The invention discloses a product surface lighting method and system. The method comprises the steps that after a front light source dust detection signal is received, when camera equipment receives first reflected light, first image information, shot by the camera equipment, of a to-be-detected surface is acquired; after a side light source dust detection signal is received, when the camera equipment receives second reflected light, second image information, shot by the camera equipment, of the to-be-detected surface is acquired; and after the first image information and the second image information are subject to image processing respectively, dust information is extracted from the first image information and the second image information which are obtained after image processing, and thesize and position of dust on the to-be-detected surface are confirmed according to the dust information. Through the product surface lighting method, the position of transparent and non-transparent dust on the to-be-detected surface of a transparent or non-transparent to-be-detected product can be precisely positioned, the size of the dust also can be confirmed, and therefore dust removal efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of dust detection, in particular to a method and system for polishing the surface of a product. Background technique [0002] In the manufacturing process of display panel devices, other optical devices and precision devices, the cleanliness of the product surface is an important indicator for evaluating product quality. In particular, whether there is dust on the surface of the LCD screen can directly reflect the cleanliness of the LCD screen and the quality of the LCD screen. [0003] In the existing technology, when dust detection is performed on the product surface of the liquid crystal screen, it is mainly to detect the highly transparent dust on the transparent liquid crystal screen, but the opaque dust on the transparent liquid crystal screen cannot be detected at the same time, and, For the opaque LCD screens that currently occupy a large proportion, the opaque dust and highly transparent dust on th...
