This paper simultaneously calibrates odometry parameters and the relative pose between a monocular camera and a robot automatically. Most camera pose estimation methods use natural features or artificial landmark tools. However. there are mismatches and scale ambiguity for natural features; the large-scale precision landmark tool is also challenging to make. https://www.ngetikin.com/special-pick-MVP4-Moisture-Vapor-Protection-Anti-Fracture-and-Noise-Reduction-Membrane-special-save/
