The PID Extractor software has been developed to extract parallax three-dimensional data from an image stream which then creates enhanced terrain and object visualization.¹ The software gathers parallax information from captured video footage shot with existing standard video cameras and lenses. The parallax information is then displayed in an autostereoscopic manner to reveal irregularities in terrain features, unrecognized objects in military settings, and unique facial features. The PID software provides a tool set for critically aligning images from two or more subject volumes with parallax differences and whose visual fields overlap in some portion of each of the image. A first image with an area of interest is critically aligned to a second image with the same area of interest but with a parallax difference. The images are aligned by means of a software viewer whereby the areas of interest are critically aligned along their translational and rotational axes to converge at some point. This is accomplished by alternating views of each image at between 2 to 60 Hz and adjusting the axial alignment of each image relative to one another until a critical alignment convergence is achieved on a sub-pixel level at a point in the area of interest. Autostereoscopic viewing is achieved by proper presentation of critically aligned images with parallax differences.²
