Run automatic structure-aware incremental SfM reconstruction.

This function runs the full SfM pipeline: feature extraction, matching, geometric verification, and incremental reconstruction with hybrid point+line registration and structure triangulation.

The input reconstruction needs camera intrinsics and image list but NOT poses. The pipeline estimates poses from scratch (incremental SfM). The reconstruction is passed in-memory to avoid COLMAP’s binary format which drops unposed frames/images on write.

Parameters:

options – Configuration options
image_dir – Path to images
output_dir – Output directory for results
recon – In-memory Reconstruction with cameras and images (no poses required)
db_path – Optional COLMAP database (default: run frontend)
structure_db_path – Optional structure database (default: run frontend)
neighbors – Optional image neighbors for frontend

Returns:

Path to output directory containing reconstructed models
