摘要：针对电子元器件的表面缺陷对其性能和品质有直接影响的问题，基于图像处理技术，以晶振外壳缺陷的检测为例，研究了电子元器件表面缺陷的检测技术。首先建立了检测系统平台，然后对所获取的图像进行分析和检测目标分割,并由生成的灰度共生矩阵计算纹理特性值。基于惯性值对纹理的深浅具有敏感性,比较研究之后，采用了惯性值作为检测表面缺陷的指标。试验结果表明该方法能够有效检测平面缺陷。

Abstract: Aiming at the Influence of electronic components surface quality for its properties and performance, surface defect detection technology was researched based on image processing technology, and the detection of crystal oscillators shell was used as an example. Firstly, the detection system platform was set up. Then, the treatment of acquainting images was fulfilled and grayscale co-occurrence matrix was generated. Because the inertia value is sensitive to the depth of the texture, after the comparative study of the value of texture characteristic, the inertia value was selected as the target of identification of the crystal surface defects. The research results show that this method can effectively detect planar defects.
Key words: surface defects; crystal oscillators shell; image processing; texture characteristic
