Abstract

Techniques for optical flow translation estimation by an inside-out location tracking system may include generating an updated distance parameter by optimizing a distance parameter using a translation vector and a set of other fixed terms of a homography for a set of matched image point pairs in an image, determining whether to keep or to discard the updated distance parameter, optimizing the translation vector using a current distance parameter, either the updated distance parameter or a prior distance parameter that was retained, thereby generating an updated translation vector. An optical flow translation method also may include evaluating for convergence, and iteratively optimizing the distance parameter and the translation vector until there is convergence. Once there is convergence, a current updated translation may be output. Convergence may depend on one or more predetermined thresholds relating to a size of parameter updates, an error reduction, and/or a number of iterations.
