As urban road intersections are prone to traffic congestion and traffic accidents, monitoring the crossing of vehicles and predicting the state is needed to reduce traffic congestion, regulate driver behavior and prevent accidents. Background subtraction and mean shift tracking are used to track vehicles. The whole monitoring process is as following. Firstly, secondary selected strategy is used to...
This paper is based on NDRC project "National Large and medium-sized agricultural products market informatization construction projects," developing the logistics process of real-time tracking management system for real-time Management of agricultural products in China. The real-time monitoring system of the logistics is designed with four subsystems: testing the temperature and humidity...
An improved monocular vision method is studied for intelligent vehicle to detect the preceding car in the structural road environment. Through identifying the edges of the car, the object is detected; the false object is eliminated and the eligible object expressed as a 2-D model is acquired. Then the location of object in the next frame is predicted by Kalman filter, and the object is detected near...
This paper presents a platoon control algorithm, which does not require an exact model of a vehicle and is robust against model uncertainties. The suggested platoon control scheme in this paper consists of a headway controller and a velocity/acceleration controller while the velocity/acceleration controller adjust the output of the vehicle for tracking the command from the headway controller. We also...
The aim of this paper is to carry out a comparison between several algorithms of the Kalman filters family for nonlinear systems. Alter having presented the most popular of them and showed its limitations, we introduce some new Kalman filters and compare them for the vehicle localization problem. This comparison is based on the predictive step what corresponds to the worst case that it can occur in...
This paper proposes a novel discrete trajectory tracking controller for a class of nonholonomic vehicles. Using existing velocity control laws based on the kinematic model and backstepping technology, the proposed discrete controller can accommodate not only traditionally continuous trajectories but also trajectories involving discontinuity points, while retaining the stability proved by Lyapunov...
