PROBLEM TO BE SOLVED: To provide a camera calibration device capable of suppressing a wrong attitude from being specified as a fitting attitude of an on-vehicle camera owing to an inclination of a vehicle.SOLUTION: A camera calibration device comprises a first inclination sensor 51 which detects an angle of inclination of a front camera 5 to a horizontal plane, and a vehicle body-side inclination sensor 3 which detects an angle of inclination of a self-vehicle to the horizontal plane. Detection results that the first inclination sensor 51 and vehicle body-side inclination sensor 3 output are stored in a memory 12. A vehicle attitude specification part that a control part 1 comprises specifies a vehicle attitude to the horizontal plane from a most frequent value of the detection result of the vehicle body-side inclination sensor 3, and a fitting attitude specification part specifies a vehicle attitude influence quantity as a quantity by which the vehicle attitude affects the detection result of the first inclination sensor 51, thereby specifying the fitting attitude of the front camera 5 by removing the vehicle attitude influence quantity from a most frequent value of the detection result of the first inclination sensor 51.SELECTED DRAWING: Figure 1 |
