Semi-global matching (SGM) is a computer vision algorithm for the estimation of a dense disparity map from a rectified stereo image pair, introduced in 2005 by Heiko Hirschmüller while working at the German Aerospace Center. Given its predictable run time, its favourable trade-off between … Meer weergeven Pixelwise stereo matching allows to perform real-time calculation of disparity maps by measuring the similarity of each pixel in one stereo image to each pixel within a subset in the other stereo image. Given a … Meer weergeven The idea behind SGM is to perform line optimisation along multiple directions and computing an aggregated cost $${\displaystyle S(p,d)}$$ by summing the costs to … Meer weergeven • 3D reconstruction • Computer stereo vision • Structure from motion Meer weergeven The main drawback of SGM is its memory consumption. An implementation of the two-pass 8-directions version of the algorithm requires to store $${\displaystyle W\times H\times D+3\times W\times D+D}$$ elements, since the accumulated cost volume … Meer weergeven • "Stereo vision".
