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 quality of the results and … See more 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 rectified … See more The idea behind SGM is to perform line optimisation along multiple directions and computing an aggregated cost The cost is … See more • 3D reconstruction • Computer stereo vision • Structure from motion See more The main drawback of SGM is its memory consumption.
