Camera Calibration Device And Camera Calibration Method
Abstract: Provided is a camera calibration device with which it is possible to easily and highly precisely estimate camera parameters without installing special calibration equipment or carrying out a measurement of three dimensional coordinates of a reference point which is employed in the calibration. A normal vector acquisition means (81) acquires from an image of a camera to be calibrated a normal vector which is perpendicular to a reference horizontal plane. A rotational matrix estimation means (82) projects the obtained normal vector in a virtual plane for projection which is perpendicular to the horizontal plane which is the reference of the normal vector evaluates that the projected normal vector is perpendicular to the reference horizontal plane and estimates a rotational matrix which is to be employed in the camera calibration.
