New camera pose refinement method bypasses triangulation errors

Researchers have developed a new method for camera pose refinement that avoids triangulation, a common step that can introduce errors. This triangulation-free approach, which expresses structure as scalar depths, maintains the accuracy of initial coarse priors from mobile AR frameworks. The technique also incorporates graduated non-convexity, allowing it to handle significantly larger errors in the initial priors than existing methods, achieving robust results even with substantial perturbations.
