US Patent 10259383 Rear collision alert system

An apparatus comprising a sensor and a processor. The sensor may be configured to capture video frames of an environment near a vehicle. The processor may be configured to (i) receive the video frames from the sensor, (ii) perform video analytics on the video frames and (iii) generate a control signal in response to the video analytics. The video analytics may analyze visual content in the video frames to identify an object approaching the vehicle. The video analytics may determine an expected path of the object approaching the vehicle. The control signal may be configured to generate a warning for the object approaching the vehicle if the expected path poses a collision hazard with the vehicle.
