Method and apparatus for calibrating a video display overlay
First Claim
1. An apparatus for calibrating a video display overlay, comprising:
- a calibration workstation having calibration indicia disposed therein;
an image capture device adapted to be vehicle-mounted, the image capture device disposed within the calibration workstation and directed toward the calibration indicia, wherein the image capture device is operable to provide a reference image depicting the calibration indicia; and
an image processor electrically connected to the image capture device, wherein the image processor is operable to receive the reference image, identify the portions of the reference image that correspond to the calibration indicia, and thereby calculate a calibration data set.

Abstract
A method and apparatus for calibrating a video display overlay. The method includes the steps of providing calibration indicia, providing an image capture device and an image processor operatively connected to the image capture device, positioning the image capture device with respect to the calibration indicia, capturing an image of the calibration indicia using the image capture device, analyzing the image using the image processor to identify the portions of the image that correspond to the calibration indicia, outputting the result as calibration indicia position data, and calculating a calibration data set based on the calibration indicia position data using the image processor. The apparatus includes calibration indicia, an image capture device directed toward the calibration indicia for providing a reference image, and an image processor electrically connected to the image capture device.
