Landscape change from daytime to nighttime under augmented reality environment

AR (Augmented Reality) technology, which uses actual landscape photography captured with a camera on-site as a base and then overlays virtual objects on that landscape image, is valid for landscape simulation. In this study, we generate nightscape images by superimposing high-luminance segments (virtual objects) over darkening landscape i ages. They are adjusted due to dark adaption modification. We found that the nightscape was evaluated more highly than the daytime landscape, and we were able to quantitatively confirm that evaluations were high for landscape in twilight after sundown.
