Accurate Three-Dimensional Orientation Measurement Using Digital Images or Video

Abstract

This report discusses an approach to measuring orientation vectors and angles from video or photographs. It builds on an earlier technical report that describes a simple and straightforward means of calibrating a cameras field of view (see technical report ARMET-TR-18031 or DTIC Submission AD1083571). The methods described in the report provide measurements made with extremely high accuracy in both the two-dimensional and three-dimensional spaces. This approach corrects large-scale distortions and provides precision that is orders of magnitude beyond current capabilities from simplistic approaches such as measuring an angle using the inverse tangent of two pixel locations.
