Patent attributes
An apparatus includes an interface and a processor. The interface may be configured to receive video signals from two or more cameras arranged to obtain a predetermined field of view, wherein respective fields of view of each pair of said two or more cameras overlap. The processor may be configured to perform a fixed pattern calibration for facilitating multi-view stitching. The fixed pattern calibration may comprise (a) performing a geometry calibration process to obtain intrinsic parameters and distortion parameters for each lens of the two or more cameras, and (b) applying a pose calibration process to the video signals using (i) the intrinsic parameters and the distortion parameters for each lens of the two or more cameras, and (ii) a calibration board to obtain configuration parameters for the respective fields of view of the two or more cameras.
