An Implementation of Hyperbolic-Mirror-Based Omni-Directional Camera

An omni-directional camera combining hyperbolic mirror with regular lens is implemented. After an analysis of reflection mirror design, image formation and camera architecture, method of design of the omni-directional camera having a single view point is proposed. A method of omni-directional image warping making use of the re-projection of points in the coordinate system of real image plane to a virtual image plane is proposed. Experimental results confirmed the validity of the proposed methods. The image captured by the omni-directional camera can be used in video surveillance, object tracking, and stereo vision.
