Photogrammetry using 3D graphics and projective textures

We present a process that enables mensuration in a 3D-visualization environment using multiple overlapping images. A Virtual Projector with accurate camera information allows imagery to be projected onto terrain and feature surfaces. This method encourages the use of multiple overlapping images in VR. We present results that demonstrate the ability of this process to efficiently produce photospecific VR and accomplish accurate mensuration in a multi-image environment.
