Key Points

To introduce APERO, an open-source bundle adjustment tool designed for automatic image orientation, camera calibration, and accurate 3D photogrammetric reconstruction.
Integrated computer vision algorithms for initial parameter estimation with photogrammetric compensation for total error minimization.
Incorporated a comprehensive library of parametric distortion models for pinhole and fish-eye cameras alongside georeferencing modules.
Evaluated software performance using real-world professional benchmark datasets, including the 3D-Arch workshop dataset.
Demonstrated accurate automatic orientation and calibration across heterogeneous image sets and complex multi-view camera geometries.
Provided robust mathematical modeling for wide-angle and fish-eye optical distortions.
Enabled end-to-end geo-referenced 3D modeling workflows suitable for architectural, archaeological, and geomorphological applications.
