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

On-vehicle image processing device for vehicular control
TL;DR: In this paper, the authors propose an image processing device that includes a first camera that captures the periphery of a vehicle, specific region extracting units that extract regions, each of which is closer to the edge of an image than to the center of the image, as specific regions, and a movement amount calculating unit that calculates the amount of movement of the vehicle on the basis of image information in a plurality of specific regions.

A Combined Approach to Stereopsis and Lane-Finding
TL;DR: In this article, a new approach for vision-based longitudinal and lateral vehicle control is proposed, which uses binocular vision for lane marker detection and longitudinal vehicle control, and two modules are integrated, consisting of a new, domain-specific, efficient binocular stereo algorithm, and a lane marker detector.

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.
