TLDR
The general problem of recognizing both horizontal and vertical road curvature parameters while driving along the road has been solved recursively and a differential geometry representation decoupled for the two curvature components has been selected.Abstract:
The general problem of recognizing both horizontal and vertical road curvature parameters while driving along the road has been solved recursively. A differential geometry representation decoupled for the two curvature components has been selected. Based on the planar solution of E.D. Dickmanns and A. Zapp (1986) and its refinements, a simple spatio-temporal model of the driving process makes it possible to take both spatial and temporal constraints into account effectively. The estimation process determines nine road and vehicle state parameters recursively at 25 Hz (40 ms) using four Intel 80286 and one 386 microprocessors. Results with the test vehicle (VaMoRs), which is a 5-ton van, are given for a hilly country road. >read more

Automated driving systems: common ground of automobiles and robots
TL;DR: Intelligent transport system projects since 1980s regarded AHS as an important system, not only a single automated vehicle but also an automated platoon were developed, and the R&D focuses on automated transit buses aiming at precision docking and driving along a narrow lane and automated truck platoons aiming at energy saving.

Pavement boundary detection via circular shape models
TL;DR: A circular shape model for detecting pavement boundaries is described and it is shown that the circular shape models enjoy several critical advantages over the polynomial models without any additional increase in model complexity.

Estimation of Object Motion Parameters from Noisy Images
Ted J. Broida,Rama Chellappa +1 more
TL;DR: An approach is presented for the estimation of object motion parameters based on a sequence of noisy images that may be of use in situations where it is difficult to resolve large numbers of object match points, but relatively long sequences of images are available.
