Phone Video for Gaussian Splatting: Corners, Occlusions and Missing Views
Start phone capture by planning coverage and connected views. As you walk around a building, keep shared landmarks in adjacent frames and move to positions that reveal hidden sides. This guide uses a street corner to explain routes, turns and checks before leaving.
English narration. The video illustrates capture methods in 3D; it is not captured footage or a reconstruction result.
Start with a manageable area
Choose one facade, street corner or small space and decide where you want to view it from. Walk the route first to check the start, end, corners and occlusions, then set a clear capture boundary.
Capture from accessible places where you can walk and pause safely. Record areas you cannot observe rather than entering restricted locations to fill a gap.
Move while keeping the building in view
Move steadily along the building, keeping shared windows, corners and ground features in adjacent frames. Rotating the phone from one spot cannot reveal all hidden sides, while a fast sweep can blur the footage.
Keep the lens, focal length and capture mode consistent where possible. Avoid abrupt zooming or lens switching during capture. Check sharpness and exposure in a short clip before continuing.
Film the transition around a corner
As you approach a corner, capture intermediate positions showing both facades, then turn gradually toward the next side. Keep a corner or window from the preceding segment visible until the next segment is clearly in view.
If a turn is too fast, blocked by a passerby or missing between two clips, record the transition again. Start from an already well-covered area and reconnect to the following segment.
Reveal hidden sides and reconnect the detail
When an area under a canopy, behind a column or inside a recess is unclear, identify the missing surface before choosing a new viewpoint. Include surrounding structure in supplementary footage so the detail retains its spatial context.
Water, reflective glass and moving people cannot replace stable landmarks. Keep fixed structures such as walls, steps and door frames in view, and review reflective or moving areas carefully.
Pause and review before leaving
Inspect individual frames at the start, corners, occlusions and end. Zoom in to check detail, then look for shared landmarks between segments. Sharp but disconnected clips and continuous but blurred footage both need more capture.
Keep original videos organized by area and capture session. Do not replace them with edited transitions or social-platform copies. Test reconstruction on a small area, then inspect missing regions and floaters along the intended viewing route.
