Abstract
In integral imaging, reproducing the depth information of three-dimensional (3D) objects accurately is one of the goals of scientific researchers. Based on the existing research, this paper proposes a new, to the best of our knowledge, elemental image array (EIA) generation algorithm, which does not need to know the depth information of the spatial scene. By dividing the distance between the display lens array (LA) and the synthetic LA equally, and comparing the variance of the pixels corresponding to the partial of the display LA at different positions, it can obtain the depth information of the 3D objects accurately, and then the value of the synthetic pixel can be calculated. Thus, a new EIA with accurate depth information is generated. Finally, the proposed algorithm has been verified in experiments of both virtual objects and real objects.
