組合せHough変換を用いた線対称形状部品の検出手法

抄録

This paper proposes a method to extract symmetrical axes of industrial components that have the two-dimensional symmetrical form in an objective image. When a pair of edge pixels is supposed to be the symmetrical points by the relative location and edge directions, the Combinational Hough Transform is applied to extract symmetrical axes. The experimental results show that symmetrical axes of industrial components are extracted successfully by the proposed method. The averaged processing time to extract symmetrical axes was 1.13 second that was reduced 72% in comparison with by using the conventional method The proposed method can be applied to various industrial image applications such as alignment, measurement and inspection of symmetrical components.
