Paper Abstract

In this paper we address the registration of close range imagery to virtual urban models, using buildings and other fixed objects in a scene. We introduce a novel approach, using radiometric and spatial queries to support the registration of ground level imagery. Image registration involves the comparison of an image’s content to the information contained in a VR model, to identify in the VR model the facades that best resemble the ones contained in the processed imagery. This registration-through-queries approach allows us to use coarse information in the form of imprecisely outlined facades to perform image registration, removing the requirements for time-consuming processes like precise delineation of control point measurement. In the paper we introduce radiometric indexing schemes to support object facade queries, and present experiments to demonstrate the function of these metrics in our image registration framework.
