| 摘 要： | 在仪表制造过程中,由于加工过程中的工艺问题等多方面的原因,导致仪表表面出现划痕、擦伤、结疤等不同类型的表面缺陷,这些缺陷不仅影响产品外观,更降低了产品的质量。本文通过对划痕缺陷的建模仿真,分析其光照模型和图像的灰度变化特点,计算并归纳总结其灰度变化趋势,提出了符合划痕特征的灰度变化模式,并利用匹配这种模式的方法对划痕进行识别,具有较高的正确率。

| Abstract: | In the process of the instrument manufacturing,different kinds of surface defects will be left,crack,blend,scar are all belong to the defects.They influence the appearance of the production and the quality of the production even.Based on the modeling and simulation of the scratch,via analysis of the illumination model and image intensity changes,calculated and summarized the gray trend,this paper proposed model scratch features grayscale,and use the method of matching the model to identify scratches,the res... |
