This chapter applies anisotropic Gaussian scale space theory for modeling affine shape modifications of moving blobs in the context of vision-based driver assistance systems. First, affine blobs are detected in an image sequence and tracked; second, their scale ratios are used for the derivation of 3D motion characteristics. For example, this also allows to estimate the navigation angles of a moving camera in 3D space. The theoretical concept is explained in detail, and illustrated by a few experiments, including an indoor experiment and also the estimation of navigation angles of a car (i.e., of the ego-vehicle) in provided test sequences. The numerical evaluations indicate the validity of the idea and advantages to vehicle vision. © 2009 Springer-Verlag.
