Mapping cityscapes into cyberspace for visualization

Abstract

This work establishes a cyberspace of a real urban area for visiting on the Internet. By registering entire scenes along every street and at many locations, viewers can visually travel around and find their destinations in cyberspace. The issues we discuss here are mapping of a large-scale area to image domains in a small amount of data, and effective display of the captured scenes for various applications. Route Panoramas captured along streets and panoramic views captured at widely opening sites are associated to a city map to provide navigation functions. This paper focuses on the properties of our extended images-route panorama, addressing the archiving process applied to an urban area, an environment developed to transmit image data as streaming media, and display for scene traversing on the WWW in real time. The created cyberspaces of urban areas have broad applications such as city tour, real estate searching, e-commerce, heritage preservation, urban planning and construction, and vehicle navigation.

Digital scope on communication sheet for media interaction

“…The map overlaid on the sheet can be an atlas of world, city, convention site, exhibition room, designed interior space, human body, etc [14,15,16]. The map can also be a table of items as a brief index of categories.…”

“…A basic function ⎯ position aware display is demanded in such systems for many applications. Examples include finding location-specific data in a map [4,6,14,15,16], exploring media related to an object [1,2], viewing process at a spot, watching structure and diagnosing a part of human body, simulating various effects in a designed space, etc.…”

Employing a Fish-Eye for Scene Tunnel Scanning

“…To register cityscapes for a visual map, the route panorama has been proposed to archive street scenes [1] [2], which is a continuous image different from local panoramic views at static positions. A video camera moves along a smooth path and a long image of the path is generated with the slit scanning mechanism [3][4] [5] [6] [10] [17].…”
