Abstract: The present invention provides a method and apparatus for capturing an image of a persons head, or other object, positioned in front of a camera and accurately scaling the head based on the distance of the head from the camera. A sonar system is used determine the distance of the object to the camera. The sonar system can include a first sonar device which is operated to measure the distance of the object to a predetermined point and a second sonar device which is used to measure the distance of the camera to the predetermined point. A calculation of the distance from the object to the camera is based upon the sonar measurements. The image created by the camera can be scaled according to the distance of the object to the camera as determined with the sonar. An image created by the camera can be displayed on a screen of a computer associated with the imaging system.
