## Summary

To address the limited surface area on thin cylindrical objects that makes planar markers difficult to place, a dual-color stripe marker is proposed. It uses the cylinder's known curvature to improve monocular camera pose measurement accuracy, with the two-color boundary providing a long centerline and dots and printed edges providing features at different depths.
