A PDA-Based System for Recognizing Buildings from User-Supplied Images

摘要

This paper reports on research into and development of portable hardware that will enable users in the field to send images, and associated positional data from a PDA to a server for processing. The central aim is to provide navigational and informational services to an urban mobile user based on building recognition. The paper begins by describing the hardware before presenting research into server-side building recognition methods that operate by comparing user-supplied images with images generated by an existing 3d virtual model.
