FPGA-based lens undistortion and image rectification for stereo vision applications (Erratum)

FPGA-based multi-view stereo system with flexible measurement setup

“…Since both images have line-corresponding content in the overlapping region (i.e. horizontal epipolar lines on both images with the same y-coordinate), the complexity of the correspondence point search is reduced [14,19]. We use the well-known Semi-Global Matching (SGM) algorithm by Hirschmüller [10] for calculated a dense disparity map.…”

“…The advantage of an FPGA-based heterogeneous MVS system is that pre-processing steps and especially the computationally intensive correspondence point search, also called stereo matching, are outsourced to one or more FPGAs reducing the data streams [14]. However, the development effort of a hardware-near processing is very high.…”
