Guidance Method to Allow a User Free Exploration with a Photorealistic View in 3D Reconstructed Virtual Environments

Architectural reconstruction based on photographs is important for digitally archiving historic buildings. In addition, freely exploring a reconstructed Virtual Environment (VE) enhances users’ understanding of and interest in the background cultural information. However, reconstructed models often have errors as well as terribly distorted views when viewed from a point distant from where the pictures were taken. Because of this problem, it is difficult to allow users to freely explore in a VE while keeping photorealistic views.
