Abstract: PURPOSE: A stereo image matching device and a method thereof are provided to obtain an accurate image matching result even though brightness of a right camera is different from brightness of a left camera. CONSTITUTION: A census cost calculating unit(150) calculates a census cost corresponding to the pair of first and second pixels. A support weight calculating unit(171) calculates a right image and a left image, or support weights of second right/left images. A cost integrating unit(180) calculates an energy value of each node corresponding to the pair of the first and second pixels using the census cost and the support weights. A dynamic programming unit(190) matches images by dynamic programming based on the energy value of each node.
