A straight line detection method based on edge following and line segments integration

Abstract

We proposed a novel straight line detection method that can exclude line segments belonging to curved lines and integrates line segments of the same straight line. The proposed method links the edge pixels into strips and segments each strip into a series of line segments. Then the line segments are exploited to split the strips into strip fragments without turning points and then identify candidate straight lines from the strip fragments. Finally, model selection method is applied to integrate candidate straight lines into straight lines and extract the parameters of straight lines. Our method is proved to be effective.
