Camera-based wide-area self-posture estimation is an effective method to understand and learn about human motion, especially in sports. However, although rapid spatial tracking typically requires markers, prepositioned markers require extensive preparation in advance, and area projection markers exhibit problems in bright environments. In this study, we propose a system for spatial tracking and graphics display using vector-based laser projection embedded with M-sequence dashed line markers. The proposed approach is fast, wide-area, and can operate in bright environments. The system enables embedding and calibration of M-sequence codes in non-circular vector shapes, as well as rapid image processing recognition. We verified that the accuracy and speed of the proposed approach sufficed through static and dynamic tracking evaluations. We also demonstrate a practical application.
