Abstract

Augmented Reality (AR) marker is the key linkage between real scene and computer-generated virtual objects, but it is also visually intrusive for overall graphic design. The objective of this paper is to integrate AR and the image-switching effect of dot matrix hologram, which makes the marker invisible under a meaningful cover image from the normal observation angle. The AR marker can be detected from a specific angle. To design the dot matrix hologram, color index image and grayscale image are used to output the grating spots with different pitches and orientations on the photoresist, which lets the dot matrix hologram possesses the image switching effect. The result shows that the invisible marker on the hologram can be detected and the AR effect can be triggered. This proposed technique has a lot of potential value-added applications in the future. It not only expands 2D display to 3D virtual object presentation for amusement enhancement, but also strengthens the product's anticounterfeiting feature and brand protection.
