While outdoor Google Street View cameras capture public roads from vehicle mounts, Street View indoor mapping focuses on digitizing the interiors of commercial buildings. Mapping indoor spaces—such as hotel lobbies, banquet halls, shopping malls, university facilities, and corporate headquarters—requires precise photographic technique to ensure smooth room-to-room transitions on Google Maps. In this guide, we break down the end-to-end rules of Street View indoor mapping.
1. 1. Indoor Mapping Rules & Camera Placement
To build a clean indoor walking path on Google Maps, adhere to four essential positioning rules:
- Nodal Height (1.5m): Maintain camera lens height at 1.5 meters from floor level throughout all rooms.
- Node Proximity (3m–5m): Space camera nodes 3 to 5 meters apart along logical walking paths.
- Clear Line of Sight: Ensure each node has an unobstructed line of sight to the preceding node (avoid placing nodes behind closed doors or thick structural pillars).
- Doorway Transitions: Place one camera node directly in the center of doorways when transitioning between rooms.
- Uniform 1.5m Lens Height: Preventing vertical camera jumping during room transitions.
- 3m–5m Proximity Threshold: Essential spacing required for automated blue-line stitching.
- Doorway Centering: Positioning nodes in doorway openings for smooth room entry.
2. 2. Lighting Setup for Indoor Commercial Spaces
Commercial interiors often feature complex lighting environments, combining warm indoor ambient lights with bright sunlight through glass windows.
Use Multi-Bracketing HDR photography (capturing 3 or 5 exposures at 2EV steps) to preserve window view details while keeping indoor shadows illuminated and digital noise minimal.
- HDR Bracketing: Merging multiple exposures for balanced window and interior lighting.
- Digital Noise Reduction: Keeping ISO settings low (ISO 64 to 200) for crisp photographic detail.
- Nadir Blur / Logo Overlay: Concealing tripod legs at the bottom pole of each panorama.
Common Questions & Answers
Can I map multi-story commercial buildings on Street View?
Yes. Group panoramas by floor levels inside PanoPublish, linking stairways or elevator lobbies to connect multiple building floors on Google Maps.
What camera is best for indoor Street View mapping?
The Ricoh Theta Z1 is widely considered the top camera for indoor mapping due to its dual 1-inch CMOS sensors and RAW DNG bracketed photography.
