CALIBRATION TARGET DETECTION APPARATUS, CALIBRATION TARGET DETECTING METHOD FOR DETECTING CALIBRATION TARGET, AND PROGRAM FOR CALIBRATION TARGET DETECTION APPARATUS

摘要

without increasing the storage capacity, low-cost feasible calibration target detection device (200), on the long and photometric area setting section 22 for setting the metering area, the metering information in the metering zone with the metering unit (21) for detecting, a predetermined one direction to the other direction, the metering area, perpendicular to the one direction on the long direction of the long Accordingly, and scanning, a first profile representing a change in the metering information generated in the second direction and at the same time, the metering area on the long to the other direction as the long direction, and thus the one-way scan, the one direction of the change in photometric information represents the second generation section for generating a luminance profile profile (23), used for calibration of the vehicle-mounted camera that is included in the captured image acquired by the in-vehicle camera 20 on the basis of the first feature points of the profile and a second profile at which the calibration target, or, and a position calculation unit 30 for calculating the position of the predetermined part of the target configuration. ;
