Original Abstract Submitted
In a camera calibration apparatus, a vanishing point calculation uni calculates a “first vanishing point” in the horizontal direction based on a first coordinate pair and a second coordinate pair acquired by an acquisition unit and calculates a “second vanishing point” in the vertical direction based on a third coordinate pair and a fourth coordinate pair acquired by the acquisition unit. The camera parameter calculation unit calculates a camera parameter of a camera based on the first vanishing point and the second vanishing point calculated by the vanishing point calculation unit. Each of the first coordinate pair and the second coordinate pair is related to a part of a human horizontally distributed in a world coordinate space. Each of the third coordinate pair and the fourth coordinate pair is related to a part of a human vertically distributed in the world coordinate space.
