Research on the PCB Micro-drill Detection Based on the DNA Algorithm

Abstract

A new vision detection method has been researched in this paper, which is applied to the PCB micro-drill under 0.1mm. Firstly, the detection platform is setup, and the micro-drill image can be obtained in real time. On this basis, the DNA algorithm has been deeply studied. The threshold segmentation method based on DNA algorithm has been designed, and applied to the PCB micro-drill detection. The final experimental results show that, compared with the traditional Otsu method, the DNA segmentation method can obtain more information, which is very helpful for the PCB micro-drill detection later on.
