Using 3-d Virtual Reality Models for Image Orientation

Advances in sensor technology and computing capabilities and modalities are revolutionizing close-range image collection and analysis for geospatial applications. These advances create the need for new ways of handling and processing video datasets at quasi real time rates. In this paper we present an innovative two step orientation technique for ground level motion imagery using a 3 dimensional virtual model as control information. In the first step few select anchor frames are orientated precisely via an image orientation-through-queries approach. In the second step, intermediate frames are orientated relatively to these anchor frames through an innovative analysis of building façade variations in them. Combined, these two steps comprise a complete approach to motion imagery orientation using a VR as control information.
