360 Capture for Gaussian Splatting: Why Camera Positions Matter
A 360 camera records the view around it, but one position cannot reveal every hidden surface. To reconstruct a scene you can explore from different positions, connect multiple capture viewpoints. This guide follows rooms, doorways and corners through capture, review and supplementary shots.

Change position to reveal hidden surfaces
Turning a camera at a doorway changes its direction, but a cabinet, door frame or corner may still hide part of the room. List the viewpoints you want to explore in the reconstructed scene, then move the camera along accessible paths.
Each new position should reveal more of the scene while retaining visible corners, furniture edges or floor texture from the preceding view. Capture the connections between rooms as well as the rooms themselves.
Check the camera with a short test
Clean the lenses, check storage and battery, and keep the camera support steady. Record a short test along the planned route. Review exposure, sharpness and stitching, and check that your grip does not cover a lens.
Keep the original camera files. If panorama export is required, follow the device and software format requirements. Test the import workflow with a small area before expanding the capture.
Connect spaces through doors and corners
Capture a connected sequence outside the doorway, near the frame and inside the room. Keep the frame, floor or nearby furniture visible through the transition instead of jumping from outside to the back of the room.
Slow down at corners and reveal the other side gradually. Review the sequence: if all landmarks from the previous space disappear before the next space becomes visible, capture intermediate positions.
Check stitching and occlusions near objects
For objects close to the lenses, inspect stitching areas for misalignment, doubled edges or changing shapes. Change position and orientation so that other frames also show the important surface clearly.
Smooth-looking stitching does not establish complete coverage. Check stitching quality and coverage from multiple positions separately; a fixed distance cannot replace reviewing the actual footage.
Inspect individual frames before reshooting
Smooth playback does not guarantee sharp frames. Pause around doorways, corners and nearby objects to inspect motion blur, overexposure and occlusion by moving people. If one part of the route is weak, recapture it together with its connections.
Before leaving, check that adjacent areas share visible structures, required surfaces appear from several positions and the original files are saved. Reconstruct a small area first and inspect it from the intended viewpoints before expanding.
