Guesture based virtual walkthrough of digital heritage sites: Hampi A Indian Digital Heritage (IDH) Project

Introduction to IDH:

India Digital Heritage is a unique initiative by DST (Department of Science and Technology) supporting collaborative projects between researchers in the areas of Technology and Humanities for digital documentation and interpretation of our tangible and intangible heritage. The project highlights art, architecture and cultural legacy of the world heritage site Hampi in Karnataka, the medieval capital of the Vijayanagara dynasty.

Project Discription:

Digital preservation of cultural heritage sites is an important area of research since the accessibility of state of the art techniques in computer vision and graphics. In this project we provide a framework for a realistic walkthrough of digital heritage sites-Hampi. The framework includes 3D data acquisition, different data processing steps, coarse to fine 3D reconstruction and rendering to generate realistic walkthrough. We proposed 3D reconstruction of heritage sites using different 3D data acquisition techniques. We have developed geometry based data processing algorithms for 3D data super resolution and hole filling using Riemannian metric tensor and Christoffel symbols as a novel set of features. We generate a walkthrough of the heritage sites by rendering the 3D reconstructed models. We demonstrate the proposed framework using a walkthrough generated for the Vittala Temple at Hampi.
