Collision warning system

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.

2. The system of claim 1 , further including the image capture device, the image capture device configured to acquire image data and generate the plurality of images.

3. The system of claim 1 , wherein the at least one processing device is further configured to determine the at least one collision parameter based on an indicator of a relative acceleration between the vehicle and the object and the plurality of images.

4. The system of claim 1 , wherein the at least one processing device is further configured to determine the at least one value indicative of a Time-to-Collision (TTC) based on an indicator of a relative velocity, and to identify a change in time of the at least one value indicative of the ITC.

5. The system of claim 1 , wherein the object includes a second vehicle moving in a same direction as the vehicle.

6. The system of claim 1 , wherein the object includes a second vehicle moving in a different direction from the vehicle.

7. The system of claim 1 , wherein the object includes a second vehicle moving toward the vehicle.

8. The system of claim 1 , wherein the response includes at least one of: a visual warning, an audible warning, a tactile alarm for a driver of the vehicle, an application of the vehicle's brakes, and an alarm for individuals in the environment of the vehicle.

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.
