Research on identification method of electric bus charging socket

Abstract： With the wide application of electric bus in urban traffic, the charging work is increasing gradually. As the charging power is large, the charging cable is relatively heavy, and requires a large plug-in force, the labor intensity of manual work is great. It has a wide range of requirements to use general mechanical arm instead of manual to realize automatic plug-in of charging gun. Identifying the charging socket is the premise to realize automatic plug-in. Taking charging socket as identification object, a method of sub-pixel precision contour geometric matching detection based on Canny operator is proposed. Through the application of image processing and machine vision technology in Halcon software, the feature extraction and template matching of the target area are carried out to realize the automatic recognition of charging socket. The experimental results show that the method has good robustness in the case of external light environment.
