System and process for projecting location-referenced panoramic images into a 3-D environment model and rendering panoramic images from arbitrary viewpoints within the 3-D environment model

A system and process of morphing location-referenced panoramic images into views at nearby locations. When using panoramic images in an interactive tour, a user might desire to see the environment from viewpoints for which no panoramic images are available. This invention makes this possible. It enables a user to experience views from arbitrary locations in the environment, so as long as one or more panoramic images are available at nearby locations. In particular, this invention makes it possible to combine two non-overlapping geo-referenced panoramic video streams into a new video stream which seamlessly transitions between these streams. When used in a client-server architecture, this invention also makes it possible for the server to transmit a sparse sequence of panoramic images, and provide the user with a dense panoramic video stream, by synthesizing the missing panoramic images. Said system and process is also applicable to incomplete panoramic images, photographs, and video.
