PROBLEM TO BE SOLVED: To provide a camera calibration device capable of easily installing a marker for calibration in the calibration of a stereo camera or the like attached to a gate of an automatic ticket gate or the like and reducing the time and labor of calibration work. SOLUTION: The camera calibration device calibrates cameras at a gate 10 which has a gate path 11 and also has the cameras 12A and 12B and an object detection sensor 13, and includes: a carriage 21 freely moved in the gate path 11; a calibration marker device 20 including a marker column 22 to which markers 22A, 22B and 22C at known height positions are attached; and a processor 14 for camera calibration, for taking out the information of the marker from image information obtained by photographing by the camera and calculating a calibration camera parameter on the basis of the information of the marker when the position of the calibration marker device is detected by the object detection sensor.
