The elastic contact points of headphone jack are the research objects. This paper introduces an au-tomatic detection system which is based on machine vision principle and method. This system takes images by CCD camera and completes the height measurement of elastic contact points by using image preprocess-ing, correlation searching, edge feature detection, etc. and realize the automatic detection for the elastic contact points of headphone jack. Test results show that this machine vision system can realize the exact and fast detection for the elastic contact points. The precision is ± 0. 006mm. This new detection method can obviously improve the detection precision and efficiency for the elastic contact points of headphone jack.
