Virtual navigation of complex scenes using clusters of cylindrical panoramic images
Abstract
The traditional approach of generating novel virtual views of an object or a
scene is to render the appropriate 3-D model. The alternative is to render
directly from the original images; this approach, which is based on pixel
interpolation or reprojection, is called image-based rendering.
In this paper, we describe a technique that enables virtual navigation
within a complex environment using an image-based rendering technique. In
particular, we make use of clusters of cylindrical panoramic
images. Each cluster of panoramic images allows the user to smoothly
navigate within a particular area, say within a single room. Having a
collection of such interconnected clusters would enable the user to
seamlessly navigate within a complex environment, such as an entire floor
of a building, with each cluster representing a room. To achieve this
goal, we examine a few techniques for image-based rendering using a cluster
of cylindrical panoramic images to synthesize views from virtual
viewpoints. We also describe our method for enabling smooth transition
between clusters.
