Abstract
An image processing device includes: an extraction unit which extracts a horizontal edge line in which edge points are arranged consecutively in a horizontal direction from an image taken that contains an image of a parking frame; a detection unit which detects a three-dimensional indication body to serve as a stop position indication body in the parking frame based on the horizontal edge line extracted by the extraction unit; and a determining unit which, in a case where a plurality of the horizontal edge lines are arranged in a vertical direction in an image of the three-dimensional indication body detected by the detection unit, determines the stop position regarding one of the plurality of the horizontal edge lines other than a highest horizontal edge line in the vertical direction as corresponding to a top end line of the three-dimensional indication body.
