Abstract

Targeting from video relies upon precise image and video registration. Historically, the technology to automate this georegistration has operated using 2D transform spaces under the often naive assumption that the imaged geometry is planar. The author previously demonstrated a fast 2D-to-3D registration algorithm that removes this assumption, provided a digital elevation model (DEM) is available. Whereas the previous algorithm operated independently on each frame of a video sequence, a new 2D-to-3D algorithm is proposed that exploits the structural consistency of the imaged geometry across frames. This work presents this novel algorithm and explores its efficacy in reducing targeting error.
