DISTANCE DETERMINATION SYSTEM FOR A VEHICLE USING HOLOGRAPHIC TECHNIQUES
First Claim
1. A distance determination system for a vehicle, the distance determination system comprising:
- an apparatus for generating and displaying a pattern generated by a holographic encoded medium in operable communication with an actuator and in communication with an electromagnetic radiation source configured to produce coherent electromagnetic waves;
an imager configured to acquire image data representative of a field of view from the vehicle; and
a distance determination module in communication with the imager and configured to locate at least one feature of the pattern in the image data and determine an estimated distance between the vehicle and the at least one feature based at least in part on a known position of the apparatus, a known position of the imager, and a layout of the pattern.

Abstract
According to one aspect, a distance determination system for a vehicle includes an apparatus for generating and displaying a pattern generated by a holographic encoded medium in operable communication with an actuator and in communication with an electromagnetic radiation source configured to produce coherent electromagnetic waves. The distance determination system also includes an imager and a distance determination module in communication with the imager. The imager is configured to acquire image data representative of a field of view from the vehicle. The distance determination module is configured to locate at least one feature of the pattern in the image data and determine an estimated distance between the vehicle and the at least one feature based at least in part on a known position of the apparatus, a known position of the imager, and a layout of the pattern.

11. A method of distance determination in a vehicle, the method comprising:
-
directing coherent electromagnetic waves from an electromagnetic radiation source at a holographic encoded medium in operable communication with an actuator; controlling the actuator to move the holographic encoded medium such that a pattern is generated; acquiring image data representative of a field of view from the vehicle; locating at least one feature of the pattern in the image data to establish a detected position of the at least one feature in the image data; and determining an estimated distance between the vehicle and the at least one feature based at least in part on a known position of the apparatus, a known position of the imager, and a layout of the pattern. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
