摘要

精密鋼珠主要應用於精密工業中精密軸承的製造，一顆品質良好的鋼珠決定了機械設備之壽命，鋼珠表面瑕疵也成為需精密檢測的產品。鋼珠瑕疵主要有表面凹陷、刮痕、生鏽及金屬疲勞產生破裂。
本研究目的主要應用機器視覺對精密鋼珠表面瑕疵做分析及檢測。鋼珠本身為球體則有多個二維平面，檢測時利用相機取多張二維影像，利用影像處理技術做影像強化分辨瑕疵特性，設計出一套客製化電路系統，包含開啟電源及緊急停止機構，並配合自動化鋼珠排列機構、排料機構分辨良品及不良品鋼珠，以達成自動化設備之整合。

Precise steel ball is an important application to stainless steel bearings manufacture in the precision industry. A steel ball of high quality determines the long lifespan of the machine. Therefore, the surface of the steel ball needs detecting precisely to ensure the high quality. There are many kinds of steel ball surface defects, including dent, scratch, rust and rupture by metal fatigue.
The purpose of this study is to inspect and analyze the steel ball surface defects with the application of computer vision. Steel ball, which is a sphere, has many 2-axis flats. During the inspection, a lot of images of 2-axis flats are captured by cameras. After that, a customized circuit system, including a switch device and an emergency button, is designed with the use of image process technology which enhances images for differentiation of defects. In addition, automatic steel ball arrangement system and automatic steel ball differentiation system are also used to achieve the integration of the automatic systems for inspection of precise steel ball surface defects.
