We propose an adaptive image mapping method that removes image discontinuity, which is the main degradation factor of image quality in an integral floating display. The proposed method is based on a newly modified image mapping algorithm that removes image discontinuity for an observer at a specific location. By taking advantage of an eye tracking scheme, the modified algorithm can produce a floating 3D image in real time for moving observers as well. The observable area of the proposed system is analyzed, and we show that multiple observers in the area can view floating 3D images without interfering with one another’s views. The effect of tracking error on the floating 3D image is analyzed, and a strategy to deal with it is also given.
