In order to ensure the correct classification of connector accessories,a set of high flexibility intelligent detection system for multi connector accessories was developed.The hardware part of the vision system was composed of CCD camera,telecentric lens and parallel background light source.After image preprocessing,morphological processing and image automatic binarization,the template matching algorithm was used to realize the intelligent recognition and sorting of different types of connector accessories.The experimental results show that the recognition system has fast recognition speed,high accuracy,high degree of automation and strong flexibility.It meets the needs of actual production and has good practical value.
