Collision warning system
First Claim
Patent Images
1. A system for providing an indication of a possible collision between a vehicle and an object, the system comprising:
- at least one processing device configured to;
receive a plurality of images from an image capture device;
use the plurality of images to determine at least one collision parameter and to determine trajectories, in the plurality of images, of at least two features of the object, the trajectories being representative of movement paths of the at least two features across the plurality of images;
determine whether the vehicle and the object are on a collision course based on the at least one collision parameter and the trajectories of the at least two features of the object; and
cause a response in the system if the vehicle and the object are determined to be on a collision course.

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.

1. A system for providing an indication of a possible collision between a vehicle and an object, the system comprising:
-
at least one processing device configured to; receive a plurality of images from an image capture device; use the plurality of images to determine at least one collision parameter and to determine trajectories, in the plurality of images, of at least two features of the object, the trajectories being representative of movement paths of the at least two features across the plurality of images; determine whether the vehicle and the object are on a collision course based on the at least one collision parameter and the trajectories of the at least two features of the object; and cause a response in the system if the vehicle and the object are determined to be on a collision course. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. A vehicle, comprising:
-
a body; an image capture device having at least one field of view relative to an exterior of the body, the image capture device configured to acquire image data at time intervals to provide a plurality of images; at least one processing device configured to; receive the plurality of images from the image capture device; use the plurality of images to determine at least one collision parameter and to determine trajectories, in the plurality of images, of at least two features of an object, the trajectories being representative of movement paths of the at least two features across the plurality of images; determine whether the vehicle and the object are on a collision course based on the at least one collision parameter and the trajectories of the at least two features of the object; and cause a response in the vehicle if the vehicle and the object are determined to be on a collision course.

10. A method for providing an indication of a possible collision between a vehicle and an object, the method comprising:
-
receiving a plurality of images from an image capture device; using the plurality of images to determine at least one collision parameter and to determine trajectories, in the plurality of images, of at least two features of the object, the trajectories being representative of movement paths of the at least two features across the plurality of images; determining whether the vehicle and the object are on a collision course based on the at least one collision parameter and the trajectories of the at least two features of the object; and causing a response in the vehicle if the vehicle and the object are determined to be on a collision course.
