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; determine at least one collision parameter based on an indicator of a relative acceleration between the vehicle and the object, wherein the indicator of the relative acceleration is determined based on the plurality of images; compare the at least one collision parameter with a predetermined threshold; and cause a response in the system if the comparison between the at least one collision parameter and the predetermined threshold indicates a possible collision between the vehicle and the object.
