An Automatic Collision Avoidance System Based on LiDAR

Applied Mechanics and Materials, 2014
For vehicle-borne LiDAR, a mathematical model is built for the computation and reconstruction of laser point cloud with the scanning data, GPS data and IMU data. 3D point cloud of the road and the scenery on the both sides of the road is obtained. Then according to the trajectory of the vehicle, 3D roaming for the scenery on the both sides of the road ...

Automatic Collision Avoidance Manoeuvres for Surface Ships

OCEANS 2019 - Marseille, 2019
This paper discusses a method to transfer the conventional nautical approach to plan and execute collision avoidance (CA) manoeuvres for surface vessels into an automatic operation. The method requires a digital manoeuvre plan or rather the planned route berth to berth based on specific dynamic motion model of the vessel.

Automatic Air Collision Avoidance System Testing

AIAA Modeling and Simulation Technologies Conference, 2015
The Automatic Air Collision Avoidance System (Auto ACAS) is a technology under development by the Air Force Research Laboratory in partnership with Lockheed Martin. Auto ACAS provides last resort air-to-air collision protection during air combat training operations by automatically maneuvering aircraft away from each other while minimizing interference

INTERNATIONAL COLLISION REGULATIONS FOR AUTOMATIC COLLISION AVOIDANCE

1996
This thesis considers the relationship between collision regulations and an automatic collision avoidance system (ACAS). Automation of ship operations is increasingly common. The automation of the collision avoidance task may have merit on grounds of reduced manual workload and the elimination of human error.

Automatic pre-crash collision avoidance in cars

IEEE Intelligent Vehicles Symposium, 2004, 2004
In recent years, a number of European Commission funded projects have investigated how the objective of increasing pedestrian safety can be attained by means of intelligent driver assistance systems. The results already at disposal show that, while in the long range case, a warning system, to alert the driver as soon as a vulnerable road users (VRU) is

Automatic collision avoidance using model-predictive online optimization

2012 IEEE 51st IEEE Conference on Decision and Control (CDC), 2012
In many traffic emergency situations a collision cannot be prevented by braking alone. Therefore, we propose an obstacle avoidance algorithm that simultaneously optimizes steering and braking. As an emergency scenario approaches the driving limits, a strong nonlinear constraint between braking and cornering develops, suggesting the formulation of a ...

The Study for Ships Automatic Collision Avoidance System

IFAC Proceedings Volumes, 1992
Abstract In order to get safety of saling ships and reduce the risk of collisions, an automatic collision avoidance system is very useful. The principle of automatic collision avoidance and the relative mathematical model are given in this paper. The paper presents also algorithms for calculating the course, relative velocity, true velocity, true ...

A semi-automatic handheld mechatronic endoscope with collision-avoidance capabilities

Proceedings 2000 ICRA. Millennium Conference. IEEE International Conference on Robotics and Automation. Symposia Proceedings (Cat. No.00CH37065), 2002
We describe the design and results achieved in the development of a semi-automatic mechatronic tool for computer-assisted endoscopy. The aim of our research is to reduce the risk of damage to delicate anatomical parts in minimally invasive surgical interventions.

An Automatic Collision Avoidance Approach to Assist Remotely Operated Quadrotors

2017
The use of quadrotors to civilian and military missions has been increased and the challenges involved on controlling it, mainly in indoors and restricted environments, has been attracting robotics researchers. Thus, an automatic collision avoidance approach is of utmost importance in this scenario, given the difficulty of control and the risk of ...
