01 / IMPLEMENTATION & CONTRIBUTION

What the work involves

Local additions wrap upstream VGGT with ONNX sky-mask preprocessing, confidence-based point filtering, reconstruction export, and geometry inspection tools.

Technical depth

ONNX sky segmentation, VGGT depth and camera prediction, depth unprojection, point filtering, and interactive inspection of the reconstructed geometry.

02 / RESULTS

What came out of it

Reconstruction and visualization scripts produce inspectable point-cloud artifacts with sky filtering.

Implementation notes, project records, and supporting artifacts.

Source context & project scope

The original VGGT architecture and model weights are upstream. Local script presence does not establish a new model or a quantitative reconstruction result.

Reconstruction quality and physical-scale accuracy remain unbenchmarked.

Adds sky segmentation and filtering around upstream VGGT inference and geometry utilities.
