VEHICLE POSITIONING METHOD AND ITS SYSTEM
First Claim
1. A vehicle positioning method, comprising steps of:
- (a) mounting multiple visible marks in a photographing-available range of a camera mounted in front of one vehicle, wherein each visible mark contains a position information related to a location of the visible mark;
(b) capturing one of the visible marks;
(c) image-processing the captured visible mark to read the position information thereof, and calculating a distance between the captured visible mark and the vehicle; and
(d) calculating GPS coordinates of the vehicle according to the position information of the captured visible mark and the distance.

Abstract
A vehicle positioning method and its system are disclosed. The vehicle positioning method has a camera adapted to be mounted in front of a vehicle, multiple visible marks mounted in a photographing-available range of a camera, and a vehicle positioning system. Each visible mark contains a position information related to a location of the visible mark. The vehicle positioning system receives an image of the visible mark captured from the camera and image-processes the image to read the position information of the captured visible mark. The vehicle positioning system further calculates a distance between the captured visible mark and the vehicle and then further corrects the position information of the captured visible mark to have GPS coordinates of the vehicle.

7. A vehicle positioning system, comprising:
-
a camera mounted in front of a vehicle; multiple visible marks, each of which is mounted within an available range of the camera and contains a position information related to a location of the visible mark; and a vehicle positioning device mounted inside the vehicle and electronically connected to the camera and having; an image processing module electronically connected to the camera to receive an image of the visible mark captured by the camera and image-processing the image to read the position information of the captured visible mark; a local position calculating module electronically connected to the image processing module and the camera to obtain the image and the position information of the captured visible mark to calculate a distance between the captured visible mark and the vehicle, and then outputting the position information of the captured visible mark and the distance; a vehicle position calculating module electronically connected to the local position calculating module to receive the distance and the position information of the captured visible mark, wherein the vehicle position calculating module corrects the position information of the captured visible mark to have GPS coordinates of the vehicle. - View Dependent Claims (8, 9, 10, 11, 12)
