Circle Marker Based Distance Measurement Using a Single Camera

Yu-Tao Cao, Jian-Ming Wang, Yu-Kuan Sun, and Xiao-Jie Duan
Abstract—A new distance measurement method with the use of a single camera and a circle marker is presented. The distance measurement is based on the idea that a circle marker at a longer distance forms a smaller image when the parameters of the imaging system remain unchanged. Firstly, the image region of the circle marker is segmented and rotation correction algorithm is designed and applied to recover the supposed image region when the circle marker is perpendicular to the camera optical axis. The distance value can be calculated by the corrected image region area and pinhole camera model. Finally, experimental results show that distance information can be retrieved by the proposed method.

Index Terms—Pinhole imaging, circle markers, area, distance.
