Titel: Progress in Real-Time Stereo Vision
The performance of future driver assistance systems - as well as the potential of au-
tonomous robots - depends on precision, robustness and completeness of their envi-
ronment perception. The urban scenario in particular poses high demands on the
computer vision, since dangerous situations have to be recognized fast and with high
confidence. The talk will present a dense stereo analysis scheme with real-time ca-
pability. Recently developed methods to reach maximum precision in sub-pixel accu-
racy will be described. Most known stereo systems concentrate on single image
pairs. It will be shown that a smart fusion of stereo vision and motion analysis (optical
flow) gives much better results than classical frame-by-frame reconstructions. The
basic idea is to track points with depth known from stereo vision over two and more
consecutive frames and to fuse the spatial and temporal information using Kalman
filters. The result is an improved accuracy of the 3D-position and an estimation of the
