Complete approach to automatic identification and sub-pixel center location for ellipse feature

XUE Ting1,SUN Mei2,ZHANG Tao1,WU Bin3(1.College of Electrical and Automation Engineering,Tianjin University,Tianjin 300072,China;2.Tianjin Engine Research Institute,Tianjin 300072,China;3.State Key Laboratory of Precision Measuring Technology and Instruments,Tianjin University,Tianjin 300072,China)  
To meet the need of automatic image features extraction with high precision in visual inspection,a complete approach to achieve automatic identification and sub-pixel center location for similar-ellipse feature is proposed with correlative key technologies.In the method,the automatic identification of feature area is fulfilled based on the edge attribute,and the sub-pixel center location is accomplished with the least-square approach.The experimental result show that automatic identification and higher precision sub-pixel center location for similar-ellipse feature can be achieved with this mthod.Meanwhile this method can meet the need of instrumentation of visual inspection because of easy realization and without man-machine interaction.
