Method for deciding the position of an observer, and an observer tracking 3D display system and method using that

摘要

The present invention provides an observation position indicator to the observer, if the observer is not in a three-dimensional image viewing position ( to be guided by the Indicator), the observer location method and relates to a three-dimensional observer tracking display system and method using the same, according to the method of determining the position of the viewer, one image of the viewer acquired by the camera detecting a center position of the eyes of the observer in; Obtaining the internal parameters of the camera information; Left / right rotation angle () to calculate the phase with the detected position of the center of the eyes and the focal length of the camera; The camera's center and distance information for a specific point to the up / down rotation with a central location for each of the two eyes () and calculating; And a calculating value ( z ) the distance between the observer and the image display device using the calculated right / left rotation angle and distance information up to a certain point and the center of the camera.
