Abstract
A vehicle for collision avoidance assistance may include: a camera to obtain an image of an object behind the vehicle, and obtain coordinates of a feature point spaced apart from the object, a controller, and a notification unit to output a collision warning. In particular, the controller sets an estimated value of a vector indicating a state of the vehicle based on coordinates of the vehicle, coordinates of the object, and the coordinates of the feature point, determine a predicted value of the estimated value of the vector based on a result of differentiating the estimated value of the vector with respect to time, correct the predicted value, determine the estimated value of the vector, and calculate a distance between the camera and the object to transmit a collision warning signal to the notification unit.
