There is provided a calibration apparatus for calculating a camera installation parameter with respect to a flat surface without preparing two sets of parallel lines on the flat surface, with respect to which the camera installation parameter is to be obtained. An acquirer acquires a photographed image of two linearly-extending lines substantially perpendicular to a flat surface. An extractor extracts the two linearly-extending lines from the acquired image through image processing. A calculator calculates a vanishing point from the extracted two linearly-extending lines and calculates a camera installation parameter with respect to the flat surface on the basis of coordinates of the vanishing point and given coordinates different from the coordinates of the vanishing point.
