Abstract: PURPOSE: A method and a device for matching image, and an object detecting apparatus using the same are provided to generate a disparity map with high reliability by removing and interpolating the disparity map with low reliability. CONSTITUTION: An initial matching unit(410) matches a stereo image and generates an initial disparity map. A disparity remover(420) calculates the reliable value of the disparity values of the disparity map and compares the reliable value with the reference value. The disparity remover removes the disparity value with the reliable value below the reference value. A disparity interpolator(430) interpolates the disparity value with low reliability, and generates and outputs the interpolated disparity map.

Abstract: PURPOSE: An object feature extraction device for accurately extracting the feature of object regardless of the targets of the various shapes is provided to accurately extract the specific information of a road using a v-parallax map. CONSTITUTION: If a time difference map of an image of a target is inputted, a v-time difference map generator(110) creates the v- parallax map through a parallax map. A binarizer(120) binarizes the v- parallax map through the maximum frequency according to a column and a row. A common unit extractor(130) creates the commonly binarized v-time difference map by the extraction of a common unit of a v-time difference map binarized by column and a v-time difference map binarized by row. An interpolator(140) outputs the feature information of the object by the interpolation of the collaboration binarization of the v- parallax map.
