360° vision system for a vehicle
First Claim
1. A vehicle environment monitoring system comprising:
- a camera mounted on top of said vehicle;
a conical reflector in operative relation to said camera, said camera and said reflector providing a 360°
field of view image around said vehicle; and
a controller adapted to detect objects within said image, determine a reference angle between said vehicle and a detected object from said image, and generate a distance value between said vehicle and said detected object as a function of a lane width value (w) and said reference angle (q).

Abstract
A vehicle monitoring system including a camera mounted on top of the vehicle reflector in operative relation to the camera. The camera and the conical reflector provide a 360° field of view image around the vehicle. A controller is also included is adapted to detect objects within the field of view image, and determine a reference angle between the vehicle and a detected object. The controller also generates a distance value between the vehicle and the detected object as a function of a lane (w) and a reference angle (q). In one embodiment, the system includes an overhead-view display system including a reference vehicle indicator representative vehicle within the environment and an indicator element adapted to display the detected object with respect to the vehicle indicator as a function of the distance value.
