To provide a calibration device in which the calculation accuracy of the position of a calibration index can be improved.SOLUTION: An on-vehicle camera fitting angle detection device 100 comprises: a camera 52 which is mounted on a vehicle and images a calibration index included in a calibration sheet arranged in the periphery of the vehicle; a center position calculation unit 120 which, from the image of the calibration index captured by the camera 52, calculates the center position of the calibration index; a camera posture calculation unit 130 which, based on the center position calculated by each center position calculation unit 120, 150, calculates the posture of the camera 52; a top view image generation unit 140 which, based on the camera posture calculated by the camera posture calculation unit 130, generates a top view image of the calibration index; and a center position calculation unit 150 which, from the top view image of the calibration index, calculates the center position of the image.SELECTED DRAWING: Figure 3
