IMG-3D / Sensor-Assisted Scan Lab

01 / INPUT

Move sideways around a stationary, textured object, keeping it centered. Aim for 8–18° between views, 60–85% visual overlap, and a steady phone. Gyro helps estimate orientation, not position.

Camera & motion permissions require HTTPS. Move around the object, not just rotate in place.

FOREGROUND CUT OFF

Reduce distant background geometry. Mesh density, edge filter and foreground cut can be reapplied to the current scan.

Prioritize nearby subject features Allow low-quality keyframes

Depth inference runs locally with WebGPU or CPU fallback. Image correspondences + robust depth scaling establish pose; optional gyro orientation can improve registration when it agrees with visual matches. Rejected views are not fused.

Drag to orbit the mesh; pinch or wheel to zoom. Camera grid is an image reference, not live AR tracking. On a phone choose SPLIT VIEW to monitor both source and reconstruction.
