PURPOSE: A surround view system camera automatic correction external variable is provided to easily perform system compensation by offering the external variable of all cameras. CONSTITUTION: One set of markers is separated as predetermined distance(200). The marker is arranged in a target object. The marker is arranged on single plane. An external variable of the camera is calculated from each marker(210). The processes are repeated for the different camera(220). [Reference numerals] (200) One set of markers is separated as predetermined distance; (210) External variable of the camera is calculated from each marker; (220) Processes(200,210) are repeated for the different camera; (230) External variations of second set of cameras against external variations of other cameras obtained from process(220) are calculated; (240) External variations of third set of cameras relative origin are estimated; (250) External variations of process(240) are optimized; (253) Reprojection errors of marker set are minimized using the estimation results of process(24); (255) Regulating using additional marker set placed in the front of each camera; (257) Difference between of process(230) on other cameras is minimized; (300) Results are outputted
