Paper Abstract

In the 1995 Collision Avoidance and Automated Traffic Management Sensors Proceedings we presented a stereo vision based approach for detecting the relative location of other vehicles in highway driving. This system was able to track other vehicles which were within the stereo pair visual field of view. In addition, important camera position variables such as inclination angle and camera height were dynamically calculated from image data without the need for external sensors. In collaboration with industrial partners we have tested the algorithm on additional video information under a number of different driving situations. The affect of noise in the camera geometry estimate on the algorithm's performance was also examined. As a result of these tests and the additional requirement of real time performance, a number of modifications were made to the algorithm to increase both its reliability and computational efficiency. We present the results of the testing as well as the algorithmic changes here.
