A Method for Tracking Road Objects

摘要

In this paper, we present a new road traffic monitoring approach for a highway control and managementsystem called RoadGuard. This system copes with several challenges in this type of applications in order tocount and track road objects robustly. It adopts a novel approach for tracking road objects, first, todetermine continuously their positions on the road, and then it uses vehicle positions to estimate theirtrajectories. The trajectory analysis provides vital information to control and manage highway traffic. Inthis paper, our main contribution is a tracking method based on a coherent strategy where both region andobject information are used to establish objects correspondence over time. Our method operates in twophases: a spatial analysis that uses a multilevel region descriptors matching in order to identify objectinteractions and particular object states; and a continuous temporal analysis applied to cope with trackmanagement issues. As demonstrated experimentally, the proposed method can detect, track and countroad objects accurately in highway videos that include several constraints. In addition, it produceseffective and stable road objects tracking.
