Abstract: Embodiments provide image display systems and methods for extrinsic calibration of one or more cameras. More specifically, embodiments are directed to camera extrinsic calibration approach based on determining intersection of the rays projecting from the optical centers of the camera and a reference camera. Embodiments determine the relative position and orientation of one or more cameras given image(s) of the same target object from each camera by projecting measured image points into 3D rays in the real world. The extrinsic parameters are found by minimizing the expected 3D intersections of those rays with the known 3D target points.
