Vehicle and control method thereof

A control method of a vehicle, the control method comprising:

• receiving a first image captured by a first camera mounted on the vehicle, wherein the first image is captured in a first direction, the first direction being an optical axis direction of the first camera;
• receiving a second image captured by a second camera mounted on the vehicle, wherein the second image is captured in a second direction perpendicular to the first direction, the second direction being an optical axis direction of the second camera;
• receiving a third image captured by a third camera mounted on the vehicle, wherein the third image is captured in a third direction perpendicular to each of the first direction and the second direction, the third direction being an optical axis direction of the third camera;
• detecting calibration markers from the first image, the second image, and the third image;
• calibrating a first movement value in the optical axis direction of each of the first camera, the second camera, and the third camera;
• calibrating a second movement value in the second direction of the first camera based on the calibrated first movement value in the optical axis direction of the second camera;
• and
• calibrating a third movement value in the third direction of the first camera based on the calibrated first movement value in the optical axis direction of the third camera;
• and
• calibrating a capture area of the first camera.
