Abstract

The invention relates to a spectacle lens flaw detection system which comprises information processing equipment (1), a stand (2), image acquisition equipment, sorting equipment, conveying equipment and package printing equipment (10). The spectacle lens flaw detection system is characterized in that the conveying equipment sequentially conveys spectacle lenses into the three different image acquisition equipment to acquire different flaw images; and the information processing equipment (1) identifies the modes, positions, sizes and quantity of spectacle lens flaws and sends control signals to the sorting equipment and the package printing equipment (10) to get rid of unqualified products and complete the packaging of qualified spectacle lenses. The spectacle lens flaw detection system disclosed by the invention can obtain the flaw images of all spectacle lenses through multiple image acquiring modes, identifies the kinds, sizes and positions of all flaws through image processing and realizes graded sorting of the spectacle lenses through the sorting equipment, thereby solving the problems of low accuracy, low speed, and the like of manual detection and greatly improves the flaw detection efficiency of the spectacle lenses.

Description

technical field [0001] The invention relates to a lens flaw detection technology, in particular to a lens flaw detection system realized by using machine vision and image processing technology. Background technique [0002] In recent years, the domestic lens industry has maintained a high-speed growth trend. my country has become the largest lens producer in the world. At present, lens manufacturers are basically still in the stage of manual inspection of lenses. The current manual inspection has the following main problems: 1. The accuracy of manual inspection is low: it will be affected by many factors such as workers' physiological differences, experience, emotion and fatigue, and the judgment standard of manual inspection is very vague, which makes it impossible to quantify lens defects Discrimination, ultimately resulting in uneven product quality, seriously affecting the sales of lenses, resulting in an increase in return orders. [0003] 2. Manual inspection speed is...
