Abstract
An object detection apparatus, using at least one processing circuit, for detecting an object in an image capturing area based on parallax information generated from a plurality of images captured by a plurality of image capturing units, includes a parallax histogram information generator to generate vertical-direction parallax histogram information indicating a frequency profile of parallax values in each of vertical row areas in a captured image based on the parallax information; and an object image area extraction unit to extract, among parallax values having frequency exceeding a given frequency threshold, a group of pixels having parallax values existing within proximity of a given parallax value and having a pixel-to-pixel interval in an image left-to-right direction within a given range as an object image area displaying an object based on the vertical-direction parallax histogram information.
