US Patent 11676397 System and method for detecting an object collision

A system for detecting an object collision includes a processor and a memory in communication with the processor with an objection collision detection module. The objection collision detection module has instructions that, when executed by the processor, cause the processor to obtain a first image and a second image of a scene from a camera sensor mounted to a vehicle, determine a change amount between the first image and the second image, and based on the change amount, determine at least one of that an object is approaching the vehicle or the object has collided with the vehicle. The change amount represents the number of pixels with the same location value that changed intensity values between the first and second images.
