STag: A stable fiducial marker system
作者：
Highlights：
• STag is a novel fiducial marker system designed for stable pose estimation.
• In addition to the traditional square border, STag has an inner circular border.
• Circular borders can be localized more stably compared to square borders.
• STag uses the stable circular border to refine the estimated homography.
• The refined homography is more stable and can be used for stable pose estimation.
