Resumen
In this paper, we propose a reflective augmented reality (AR) display system based on integral imaging (II) using a mirror-based pinhole array (MBPA). The MBPA, obtained by punching pinholes on a mirror, functions as a three-dimensional (3D) imaging device, as well as an image combiner. The pinhole array of MBPA can realize a pinhole array-based II display, while the mirror of MBPA can image the real objects, so as to combine the images of the real objects with the reconstructed 3D images. The structure of the proposed reflective AR display is very simple, and only a projection system or a two-dimensional display screen is needed to combine with the MBPA. In our experiment, a 25cm × 14cm sized AR display was built up, a combination of a 3D virtual image and a real 3D object was presented by the proposed AR 3D display. The proposed device could realize an AR display of large size due to its compact form factor and low weight.
