Abstract

In recent years, glasses-free 3D displays are expected to play an active role in various fields and have been studied. Lenticular glasses-free 3D displays are calibrated based on a one-to-one correspondence between the ray vector emitted from the display and the ray vector observed by the camera. However, in the real world, light emitted from a single pixel on the display affects multiple pixels in the camera, so it is necessary to consider a one-to-many correspondence. In this study, we investigate a calibration method that takes into account the spread of light generated in the real environment by using the light transport matrix that shows the correspondence between the display and the camera. We obtained the light transport matrix and conducted an experiment to generate a display image calibrated to the camera position. The generated image was drawn on the display and observed using the same camera, and it was confirmed that the image was calibrated to the camera position. In the future, we aim to expand the parallax by increasing the number of cameras.
