ABSTRACT
This paper presents a technique for vehicle localization. The technique is based on processing images taken by one or more downward pointing cameras. Motion represented by shift between successive images allows us to directly measure the velocity at two points on either side of the axis of motion. From these possibly di erent velocities, we can infer the vehicle speed and turning radius and from those, the vehicle orientation, position, velocity and acceleration vectors.

Outward-Looking Circular Motion Analysis of Large Image Sequences
This paper presents a novel and simple method of analyzing the motion of a large image sequence captured by a calibrated outward-looking video camera moving on a circular trajectory for large-scale environment applications. Previous circular motion ...
Spinning beacons for precise indoor localization
SenSys '08: Proceedings of the 6th ACM conference on Embedded network sensor systemsThis work proposes the novel use of spinning beacons for precise indoor localization. The proposed "SpinLoc" (Spinning Indoor Localization) system uses "spinning" (i.e., rotating) beacons to create and detect predictable and highly distinguishable ...
