The Research on a Rapid Appearance Detection Method for Vertical Polarized Electrolytic Capacitors

Abstract:

For detecting the defects of the vertical polarized electrolytic capacitors in the process of production, an online machine vision detection method based on DSP is proposed in this paper. The hardware framework is designed emphatically with DM642 as the core processor, which has the advantages of small size, fast processing speed, low cost and low power consumption. The software workflow of the capacitors defects detection is introduced. To meet the requirement of high production and real-time detection of capacitors, a rapid appearance detection algorithm is introduced by using a few number of feature points instead of the whole. The experimental results show that the proposed method can achieve many types of defects detection of the capacitors.
