Omnivision and Wide Angle Camera Calibration and Image Correction 2. UTK IRIS Capabilities Related to Topic § Cameral calibration technique has been developed which performs equally well on a wide range of cameras, regardless of lens projection or quality of the camera. Distorted Image Corrected Image 3. Objectives and Technical Approach § Develop a more robust calibration process which reduces existing geometric constraints while improving calibration precision on camera systems with a large degree of distortion. § Simplify and accelerate image formation process of mapping points from the 3 D world to points on an undistorted image. § Study the geometry of wide-angle systems to extend properties which will be used for more precise calibration and faster reconstruction tasks. § Implement calibration of multiple cameras into a network which will improve 3 D computer vision tasks. § Using statistical information criteria in depth work was conducted to determining whether the most accurate and complex model is selected for extracting calibration parameters. 4. Applications § Calibration of multi-camera systems provide continuous, accurate, and robust monitoring of real-time surveillance systems. § Stereo reconstruction using systems with wide field of view is more exact with accurate models of lens distortions. § Simplified calibration procedures with correct distortion estimations provide real time and accurate computation of positions and velocities in traffic scenes, building surveillance, and other applications using omni-directional vision.
