Lateral Optical Geometry
Badminton Court Camera Placement Diagram
⭐ Position 1 (Side-Court Midline): Optical axis is perpendicular (90°) to smash flight path.
⭐ 1. Lateral Distance (3.0m - 5.0m)

Place tripod 3 to 5 meters (10–16 ft) outside the court sideline, aligned with the net post or short service line. This keeps the full smash trajectory in frame.

πŸ“ 2. Tripod Height (1.1m - 1.4m)

Set tripod height to chest / waist level (1.2m / 4 ft) with a slight 5°–10Β° upward tilt. This captures both the jump smash overhead contact (3.0m) and court floor impact.

πŸ”Š 3. Unobstructed Audio Path

Ensure phone microphone faces the court. Sound Assist analyzes the explosive 1.8–4.5 kHz sweet-spot crack to verify smashes within a Β±250ms coincidence window.

BWF Standard Court: 13.40m Γ— 6.10m (Top-Down View)
⭐ Position 1: Side-Line Mid-Court 98% Accuracy
Optical Viewing Angle: 90Β° (Perpendicular / Pure Lateral)
Optical Foreshortening: Zero (cos 0Β° = 1.00)
Tripod Distance: 3.5m - 4.5m from sideline
Recommended Elevation: 1.2m (Chest Level, +8Β° Tilt)
Why this position is best:

Smash velocity vector travels directly across the camera sensor plane (lateral Ξ”x displacement). Every pixel delta accurately translates to physical meters per second without perspective distortion.
