Research on the automatic visual inspection model based on extenics

This paper puts forward five-layer extension AVI model (EAVI) by combining the extension knowledge and automatic visual inspection(AVI)area knowledge. Then gives the detailed analysis process of the image acquisition layer and pre-processing layer according to the four extension thinking modes, and designs the AVI model evaluating methods. Describing and analyzing the AVI process using the methods provided by Extenics will be helpful to the research on the intelligence, generality, and the reconfigurability of the AVI system.
