Abstract

An image processing apparatus includes processing circuitry configured to obtain a range image having pixel values corresponding to a distance of an object in a plurality of captured images obtained by capturing the object on a road surface so as to extract pixel values from the range image, generate vertical direction distribution data indicating a frequency distribution of distance values in a vertical direction of the range image based on the extracted pixel values, calculate a height of the road surface in the range image before generation of the vertical direction distribution data is completed, and generate horizontal direction distribution data indicating a frequency distribution of distance values in a horizontal direction of the range image based on the extracted pixel values and the calculated height of the road surface.
