Abstract

In recent years, there has been a lot of research on autostereoscopic displays. In this work, we propose the viewpoints extension method for the stacked Pepper's Ghost method [1] for simultaneous viewing of stereoscopic images by multiple people. In the proposed method, we use three cameras to obtain the light transport matrix, which is the pixel correspondence between the display and the camera. In this way, we extended the number of viewpoints from two to three. In addition, the number of viewpoints can be extended to the number of cameras by increasing the number of cameras. In our experiments, we captured the target light field image, obtained the light transport matrix, and optimized the layer image. The experimental results showed that the optimization accuracy was lower than that for two viewpoints, but it was still possible to present disparity images from three viewpoints, confirming that the number of viewpoints can be expanded. In the future, we aim to present images more stereoscopically by presenting disparity in the vertical direction.
