The road to auto-charting
Each milestone is a devlog entry. Here's where things stand.
- ●M0 — Track ball and players through one rally with SAM 3
- ○M1 — Court keypoints → homography → real court coordinates
- ○M2 — Detect hits and bounces from ball trajectory
- ○M3 — Rally segmentation → shot sequences → MCP notation
- ○M4 — Validate against a human-charted Match Charting Project match
