How to record video for CFD testing
Positioning:
- Stand approximately 10 feet away from your subject.
- Begin walking in a complete 360-degree circle around the subject.
Framing:
- Keep the subject centered in your frame throughout the recording.
- Focus especially on the front of the rider and bike, as these areas are key for wind resistance analysis.
Camera Movement:
- Gradually vary your camera height as you move, raising and lowering it to capture multiple viewing angles.
- Maintain smooth, steady movements for clear and consistent footage.
Lighting:
- Use bright, even lighting conditions for best results.
- Natural daylight is ideal, but avoid harsh shadows that may interfere with feature tracking.
Camera Settings:
- Anything over 720p is acceptable. Try not to exceed 200mb.
- Use recording options that minimize lens distortion for the clearest footage.
Consistency:
- Maintain a consistent distance of about 10 feet throughout your circular path.
- Ensure all necessary angles of the subject are captured to help the software generate accurate 3D reconstructions.
