Today's stereo vision algorithms and computing technology allow real-time 3D data
analysis, for example for driver assistance systems. A recently developed Semi-Global
Matching (SGM) approach by H. Hirschmüller became a popular choice due to performance
and robustness. This paper evaluates different parameter settings for SGM, and its main
contribution consists in suggesting to include a second order prior into the smoothness term
of the energy function. It also proposes and tests a new cost function for SGM. Furthermore …
