VEHICLE VISION SYSTEM USING REFLECTIVE VEHICLE TAGS
First Claim
1. A vision system of a vehicle, said vision system comprising:
- a camera configured to be disposed at a vehicle equipped with said vision system so as to have a field of view forward of the equipped vehicle;
an image processor operable to process image data captured by said camera when said camera is disposed at the equipped vehicle;
a tag element disposed at another vehicle, said tag element having a pattern thereat;
wherein, with said camera disposed at the equipped vehicle and when the tag element is present in the field of view of said camera, said image processor is operable to process image data by said camera to determine the pattern of the tag element present in the field of view of said camera;
wherein said image processor compares the determined pattern of the tag element to a database of patterns and classifies the tag element at least in part responsive to determination that the determined pattern of the tag element generally matches a pattern of the database; and
wherein the pattern of the tag element disposed at the other vehicle includes information at least pertaining to a type of the other vehicle.

Abstract
A vision system of a vehicle includes a camera configured to be disposed at a vehicle so as to have a field of view exterior of the vehicle. A tag or retroreflective element is disposed at another vehicle. With the camera disposed at the vehicle and when the tag element is present in the camera'"'"'s field of view, an image processor is operable to process captured image data to determine a pattern of the tag element present in the field of view of the camera. The image processor compares the determined pattern of the tag element to a database of patterns and classifies the tag element at least in part responsive to determination that the determined pattern of the tag element generally matches a pattern of the database. The pattern of the tag element disposed at the other vehicle includes information pertaining to a type of the other vehicle.

13. A vision system of a vehicle, said vision system comprising:
-
a camera configured to be disposed at a vehicle equipped with said vision system so as to have a field of view forward of the equipped vehicle; an image processor operable to process image data captured by said camera when said camera is disposed at the equipped vehicle; a tag element disposed at another vehicle, said tag element having a two dimensional pattern thereat; wherein, with said camera disposed at the equipped vehicle and when the tag element is present in the field of view of said camera, said image processor is operable to process image data by said camera to determine the two dimensional pattern of the tag element present in the field of view of said camera; wherein said image processor compares the determined two dimensional pattern of the tag element to a database of two dimensional patterns and classifies the tag element at least in part responsive to determination that the determined two dimensional pattern of the tag element generally matches a two dimensional pattern of the database; wherein the pattern of the tag element disposed at the other vehicle includes information at least pertaining to one of (i) a type of the other vehicle and (ii) a size of the other vehicle; and wherein, responsive to determination that the determined two dimensional pattern of the tag element generally matches a two dimensional pattern of the database, the headlamps of the equipped vehicle are adjusted. - View Dependent Claims (14, 15, 16, 17)

18. A vision system of a vehicle, said vision system comprising:
-
a camera configured to be disposed at a vehicle equipped with said vision system so as to have a field of view forward of the equipped vehicle; an image processor operable to process image data captured by said camera when said camera is disposed at the equipped vehicle; a tag element disposed at another vehicle, wherein the tag element has a coding pattern thereat; a near infrared light source disposed at the equipped vehicle and operable to emit near infrared light; wherein the tag element reflects near infrared light emitted by said near infrared light source, and wherein said camera is sensitive to near infrared light; wherein, with said camera disposed at the equipped vehicle and when the tag element is present in the field of view of said camera, said image processor is operable to process image data by said camera to determine the coding pattern of the tag element present in the field of view of said camera; wherein said image processor compares the determined coding pattern of the tag element to a database of patterns and classifies the tag element at least in part responsive to determination that the determined coding pattern of the tag element generally matches a coding pattern of the database; wherein the coding pattern of the tag element disposed at the other vehicle includes information at least pertaining to one of (i) a type of the other vehicle and (ii) a size of the other vehicle. - View Dependent Claims (19, 20)
