Hurdle Touchdown Detection
Frame-accurate hurdle touchdown timing. Pose-based foot tracking detects the moment the foot strikes the ground, computes inter-hurdle intervals, and surfaces optional vision form scores.
Pose-Based Foot Tracking
MediaPipe Pose Landmarker runs in your browser. 33 keypoints per frame, ankle Y-position used to find ground contact.
Velocity Zero-Crossing
Touchdown detected at the frame where vertical foot velocity transitions from descending to ascending. Sub-frame interpolation for precision.
Inter-Hurdle Intervals
Per-hurdle touchdown timestamps, computed intervals between hurdles, deviation from race average. Optional AI form notes.
