Recently, many researches on autostereoscopic displays have been carried out. In this work, we propose a new display configuration using the Pepper's ghost effect and a dynamic image adjustment method for a large scale autostereoscopic display. We also propose a method for extending the number of viewpoints for simultaneous viewing by multiple people. In the experiment, after constructing the device, we acquired the light transport matrix using two cameras and dynamically adjusted the video images. We observed parallax in the adjusted images, and we confirmed that the images were stereoscopic. At present, only one person can view the stereoscopic images at the same time because only two parallax images are presented. However, when acquiring the light transport matrix, we can create the video from multiple viewpoints by increasing the number of cameras. In the future, we will experiment using three cameras and confirm that the three-dimensional image presentation is possible by three parallaxes.
In this research, in order for autostereoscopic display of dual projection types to display the image with larger parallax, we improved a new optimization method of the two projector images. We achieved that aim by deriving a new update formula in addition system and adjusting the target light field and weight matrix to create the area that saturates light.
