Abstract:
PURPOSE: A stereo matching system using a dynamic programming method and method thereof are provided to output a parallax map by composing stereo matching results. CONSTITUTION: An image compensation unit(120) compensates images. A matching cost calculation unit(130) calculates junction costs for the compensated images. A stereo matching unit(140) executes a viterbi algorithm matching method using two or more PD(Penalty of Disparity discontinuity) values for the calculated junction costs. A restriction condition application unit(150) negates pixels of a closed area on each generated disparity map. A matching result synthesis unit(160) syntheses a plurality of parallax maps which negate the pixels of the closed area.
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.
