Abstract
A method of estimating a time to collision (TTC) of a vehicle with an object comprising: acquiring a plurality of images of the object; and determining a TTC from the images that is responsive to a relative velocity and relative acceleration between the vehicle and the object.
Claims16
A method of estimating a time-to-collision (TTC) of a vehicle with an object comprising the step of:
- acquiring a plurality of images of the object at known time intervals;
- determining a relative scale of the object in the images;
- and
- determining the time-to-collision (TTC) based on the relative scale and the time intervals, wherein the time-to-collision (TTC) is responsive to the relative velocity and the relative acceleration between the vehicle and the object.
A system for estimating a time-to-collision collision, the system including a camera and a processor mountable in a motor vehicle, the system operable to:
- acquire a plurality of images of the object at known time intervals;
- determine a relative scale of the object in the images;
- and
- determine the time-to-collision (TTC) based on the relative scale and the time intervals, wherein the time-to-collision (TTC) is responsive to the relative velocity and the relative acceleration between the vehicle and the object.
A system for alerting a driver to a possible collision with an object, the system comprising:
- a camera and a processor mountable in a motor vehicle, the system operable to:
- acquire a plurality of images of the object at known time intervals;
- determine the time-to-collision (TTC) based on data from the images and the time intervals;
- and
- determine based on data from the images whether the vehicle and the object are on a course that leads to a collision at the TTC.
