Basic Study on Creating VR Exhibition Content Archived Under Adverse Conditions

In this research, we propose a VR content creation method which reproduces the original appearance of the cultural properties based spherical image taken under adverse conditions. The proposed method consists of brightness adjustment and spherical image synthesis for improvement of appearance. In the adjustment of the brightness, \(\gamma \) correction is performed so that the contrast is smoothed. In the spherical image synthesis, images are selected according to the user’s eye direction, and the image is synthesized after conversion by Moebius transformation. In order to verify the proposed method, the methods were applied to spherical images taken in the real world and evaluated. In the brightness adjustment method, the similarity between feature points is improved by the proposed method. In spherical image synthesis method, it was confirmed that the deviation became small as a result of calculation of the compositional deviation between the actual spherical image taken and the synthesized image.
