Abstract
A time-to-contact estimate determination system is disclosed for generating an estimate as to the time-to-contact of a vehicle moving along a roadway with an obstacle. The time-to-contact estimate determination system comprises an image receiver and a processor. The image receiver is configured to receive image information relating to a series of at least two images recorded as the vehicle moves along a roadway. The processor is configured to process the image information received by the image receiver to generate a time-to-contact estimate of the vehicle with the obstacle.
