System for Communicating a Vehicle Position and Speed during Accident

Abstract

In this paper, this paper seeks an answer to the question: can a vehicle automatically report to the emergency units its position and speed when an accident is occurred? It presents an approach that relates to an accident detection and prevention system. It is particularly related to a system that sends a message to designated parties (such as vehicle owner and emergency helpers) when a certain speed has been detected and when an accident has been detected with a resulting speed below a certain threshold. The proposed system includes a microcontroller, modem, nock sensor, and speed selection box is used to send messages when a certain speed has been exceeded and when an accident has occurred and the resulting speed of the vehicle is less than a predetermined threshold. The message sent can be a text message sent over a GSM modem.

Overcoming Singularity of Euler Angles in Robot Pose Estimation using Axis Rotation

“…focal lengths, and image centers) , refers respectively to the feature number, frame number, and camera number (either camera 1 or camera 2 of the stereo pair) , and is the measurement noise. The Jacobian of the EKF is composed of the derivatives of with respect to the six pose parameters of equation (1). More about the EKF implementation can be found in [5], [6], and [7].…”

“…Many applications require solving this problem. For example, in [1] the location and speed of a vehicle are communicated in case of an accident. Pose estimation is used in [2] for optimizing the turning velocity of a robot.…”
