Abstract
In this paper, a novel corner detection method is presented, to extract geometrically important corners for robot applications, such as indoor mobile robot navigation or manipulation. Intensity-based corner detectors, such as the Harris corner, can detect corners in noisy environments, but have inaccurate corner positions and miss the corners of obtuse angles. Edge-based corner detectors, such as the Curvature Scale Space, can detect structural corners, but show unstable corner detection due to incomplete edge detection in noisy environments. The proposed image-based direct curvature estimation can overcome limitations in both the inaccurate structural corner detection of the Harris corner detector (intensity-based) and the unstable corner detection of the Curvature Scale Space, caused by incomplete edge detection. Various experimental results validate the robustness of the proposed method.
