People Capture

Applicable methods: Video reconstruction (phone/camera), single map reconstruction in Lixel P1 portrait mode

Special Challenges of People Capture

People are dynamic subjects with extra difficulties compared to static objects:

• People move involuntarily (breathing, blinking, shifting weight)
• Hair and clothing details are complex
• Facial expressions need to stay consistent

Full-Body People Capture

Orbit Method (Recommended)

1. The subject stands still in a natural pose
2. The photographer slowly orbits around the subject:
   • First loop: eye-level height (chest), covering front and back
   • Second loop: low position (knee height), tilting slightly upward
   • Third loop: high position (above the head), tilting slightly downward
3. Keep the total duration within 60–90 seconds

Key points:

• Tell the subject to stay completely still (do not talk, do not blink)
• Shoot quickly (it is hard for people to stay still for more than 2 minutes)
• Avoid casting the subject's shadow onto themselves

Head/Half-Body People Capture

1. The subject sits on a chair with a neutral facial expression
2. The photographer moves slowly in an arc 0.5–1 m in front of the subject:
   • From the front to 90° on the left
   • Back to the front, then to 90° on the right
   • From the front to above the head (top-down)
3. Total duration 30–60 seconds

People Capture Parameter Recommendations

People Capture Considerations

• Hair: Dark long hair easily loses detail; ensure sufficient lighting
• Glasses: Lens reflections produce artifacts; recommend removing them or using a polarizing filter
• Loose clothing: Clothing fluttering in the wind produces artifacts; choose fitted clothing
• Multi-person scenes: Capture only one person at a time, others leave the frame
