一种基于同态滤波的陶瓷防眩光处理技术研究

A Homomorphic Filtering-based Ceramic Anti-glare Processing Technique

机器视觉检测技术的普及能够有效提高企业陶瓷的生产效率,然而目前机器视觉技术在日用陶瓷检测领域的应用较少。其主要原因是:基于陶瓷的机器视觉在线检测存在一个典型问题——陶瓷眩光。此现象会严重影响陶瓷图像的采集和后续的智能处理。本论文针对陶瓷表面存在眩光的问题,提出一种基于同态滤波的陶瓷防眩光处理技术。本算法不仅可以解决眩光造成的细节不清晰问题,同时还能较清晰还原陶瓷图像的细节。实验结果表明,本文提出的防眩光算法具有较好的实用性。

With the development of machine vision detection techniques, the efficiency of product production and inspection is greatly improved. However, machine vision techniques are not widely employed in ceramic field. One of the critical reasons is that ceramic glare may significantly affect the inspection accuracy. To prevent glare from ceramic surface, this paper proposes a novel homomorphic filtering-based anti-glare scheme. As a pre-processing phase, this algorithm can effectively remove ceramic glare and facilitate high-quality ceramic image acquirement. The experimental results show that the proposed anti-glare algorithm has desired practicability.
