VEHICULAR VISION SYSTEM WITH DETERMINATION OF A BICYCLE APPROACHING FROM REARWARD OF THE VEHICLE

A vehicular vision system includes a camera and an image processor that processes frames of image data captured by the camera. With the vehicle parked, the vehicular vision system processes frames of captured image data to track a three dimensional object to determine movement of the three dimensional object relative to the parked vehicle. The vehicular vision system determines that the three dimensional object is a bicycle sideward and rearward of the parked vehicle and approaching the parked vehicle from rearward of the parked vehicle. With a door of the parked vehicle closed, and at least in part responsive to the determined bicycle being within a threshold distance to the parked vehicle and approaching a side region adjacent the door of the vehicle, the vehicular vision system generates an output indicative of determination of the determined bicycle approaching the side region adjacent the door of the vehicle.
