Center Subpixel Localization of Circular Retro-Reflective Targets

Abstract: Circle targets made from retro-reflective material(RRT) are introduced. After photographed, the approximate binaried RRT image is gotten. The precise edge position is gotten using subpixel edge detection method. Then, center of RRT is localized precisely by ellipse best fitting. Tests demonstrate that the center is localized in 0.02 pixel.
