1. A camera calibration system comprising at least one processor which implements:

  • a vanishing point detecting module configured to detect, from at least one reference detection object existing in a detection region, a first vanishing point and a second vanishing point;

    a view mode determining module configured to determine a camera view mode on the basis of a result of comparing a distance from a position in the detection region to the first vanishing point with a distance from the position to the second vanishing point, by determining the camera view mode, among a plurality of predetermined camera view modes corresponding to a plurality of predetermined camera calibration methods, that corresponds to the result of the comparing; and

    a camera calibration module configured to select a camera calibration method corresponding to the determined camera view mode among the plurality of predetermined camera calibration methods, and perform camera calibration through the selected camera calibration method,wherein the determined camera view mode corresponds to an angle between a photographing direction of a camera capturing the detection region and a horizontal plane, the angle being determined on the basis of the result of the comparing.
