Abstract
By defining an angular separation in a train of sequential images, and using an interlaced sequence of pairs of images matched by that defining angle, it is possible to create live 3D video from a single camera mounted on a remote vehicle as though in the in the immediate vicinity of the object being viewed. Such a camera can be mounted on a moving vehicle such as a plane or a satellite In addition, computational power is provided to adaptively (and predictively) smooth out motion irregularities between these image pairs, so that smooth 3D video may be obtained. Continual feature-based correlation between successive frames allows corrections for various transformations so that there is a one-on-one correspondence in size, projection, orientation, etc. between matched frames, which enables capture and display of smooth 3D video.
