Zusammenfassung:There are provided a calibration apparatus and method capable of obtaining a high-precision calibration result by taking out only feature points on a road surface from images captured by an in-vehicle camera which is a calibration target. A road surface range is estimated by using feature points appearing in an image(s) captured by a camera (a front camera 102 or a rear camera 103) that is not a camera on which the calibration is executed (a side camera 106); and the calibration is executed by using only feature points existing within the estimated road surface range from among the feature points appearing in an image(s) captured by the camera on which the calibration is executed.
