The present invention relates to a parallax information generating apparatus and method for stereo matching based on a vertical census transform based on a stereo matching operation for reducing the amount of computation for overlapping areas for operations between neighboring windows in a stereo matching operation in a stereo matching operation will be. An apparatus and method for generating parallax information through stereo matching based on vertical census conversion according to the present invention are characterized by setting a left image window centered at a specific point of a left image provided from a stereo camera, A window setting unit for setting a right image window of the same size to a point located within a maximum parallax predicted value with respect to a point while moving the right image window in the X axis direction; A vertical cell generation unit for generating a vertical cell value for the vertical region by using a brightness difference between the central pixel and the remaining pixels of the vertical region and storing the generated vertical cell value in all the vertical regions constituting the window, Using the vertical cell value for the window, And a Hamming weight bit stream of right image windows for different points located within a maximum parallax predicted value are compared with each other to obtain a Hamming weight bit stream for a left image and a right image, And a parallax information generating unit for generating parallax information.
