Abstract

An approach to achieving a light field three-dimensional (3D) display with a large viewing angular range based on spliced multi-LCDs is investigated. The light field reconstruction principle, LCD-based hardware configuration, and diffuser characteristics are analyzed. A point-to-point mapping calibration method is proposed to improve imaging performance, by using an image sensor to capture the coordinate distributions of the images on the LCD panel, projected onto the display space. By measuring the coordinate distributions, calibration is implemented considering both imaging aberration and geometrical inaccuracy of the whole system. The LCD-based experiment demonstrates that this method can achieve not only fast and precise calibration but also easy scalability, flexible depth, and angular range. A touchable floating 3D scene with correct occlusion, high image resolution, and a large continuous viewing angular range can be observed.
