Vehicle Collision Avoidance

2020
Road accidents are considered as one of the major reasons of deaths. The proposed vehicle collision avoidance system aims to increase the traffic efficiency and safety. Through the proposed system, the driver can be alerted to the surrounding hazards by communicating with other drivers.

Visually guided collision avoidance and collision achievement

Trends in Cognitive Sciences, 2000
To survive on today's highways, a driver must have highly developed skills in visually guided collision avoidance. To play such games as cricket, tennis or baseball demands accurate, precise and reliable collision achievement. This review discusses evidence that some of these tasks are performed by predicting where an object will be at some sharply ...

Visual Collision Avoidance by Segmentation

Proceedings of IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS'94), 1995
Visual collision avoidance involves two difficult subproblems: obstacle recognition and depth measurement. We present a class of algorithms that use particularly simple methods for each subproblem and derive a set of sufficient conditions for their proper functioning based on a set of idealizations.

Distributed reactive collision avoidance

Autonomous Robots, 2012
The work contained in this paper concerns a novel approach to the n-vehicle collision avoidance problem. The vehicle model used here allows for three-dimensional movement and represents a wide range of vehicles. The algorithm works in conjunction with any desired controller to guarantee all vehicles remain free of collisions while attempting to follow ...

Collision avoidance in cloth animation

The Visual Computer, 1996
For cloth modeling and animation, we use a physically based model to simulate the dynamic formation of folds, pleats, and wrinkles and the final static appearance of cloth draped over a rigid object. To simulate the behavior of the cloth and its final static appearance on the model, we propose a new collision and self-collision avoidance method to ...

Generalized reciprocal collision avoidance

The International Journal of Robotics Research, 2015
Reciprocal collision avoidance has become a popular area of research over recent years. Approaches have been developed for a variety of dynamic systems ranging from single integrators to car-like, differential-drive, and arbitrary, linear equations of motion. In this paper, we present two contributions. First, we provide a unification of these previous

Collision avoidance for nonrigid objects

Zeitschrift für Operations Research, 1988
The path existence problem and the collision detection problem for time-varying objects in a geometric scene are discussed. For a large class of spherical nonrigid objects, exact solutions of the path existence problem are developed based on decomposition techniques and graph traversal.

Collision avoidance in satellite clusters

Proceedings of the 2002 American Control Conference (IEEE Cat. No.CH37301), 2002
A collision avoidance methodology for satellite clusters is developed and simulated. A set membership algorithm is used to monitor and predict guaranteed position uncertainty ellipsoids over time. Distances between ellipsoids can be calculated on-line in order to evaluate when and how fast a collision may occur.

Formation control with collision avoidance

IEEE Conference on Decision and Control and European Control Conference, 2011
We present a formation flight control strategy featuring a collision avoidance scheme. The control algorithm is based on a Sliding Mode controller. The controller sliding surfaces account for aircraft maneuvering limitations, restricting the required velocities to a feasible set.
