A PCB Component Location Method Based on Image Hashing

摘要：

A novel method based on image hashing is proposed to locate the acquired component from a CCD DSC camera in this paper. Image hash is extracted resistant to geometric distortions. The extracted hash is used to identify the component and related defects including missing component, mistake component, inverse orientation. The proposed method is verified by experimental results.
