| #### This is the official repository for [Stereophotoclinometry Revisited](https://arxiv.org/abs/2504.08252), which is currently under review for publication to AIAA's [Journal of Guidance, Control, and Dynamics (JGCD)](https://arc.aiaa.org/loi/jgcd) |
|
|
| **Photoclinometry-from-Motion (PhoMo)** is a framework for _autonomous_ image-based surface reconstruction and characterization of small celestial bodies. PhoMo integrates photoclinometry into a structure-from-motion (SfM) pipeline that leverages deep learning-based keypoint extraction and matching (i.e., [RoMa](https://github.com/Parskatt/RoMa)) to enable _simultaneous_ optimization of the spacecraft pose, landmark positions, Sun vectors, and surface normals and albedos. |

| ## Dataset Structure |
|
|
| Each directory contains a subdirectory for each of the sites used in the paper, i.e., Cornelia (`cornelia/`), Ahuna Mons (`ahunamons/`), and Ikapati (`ikapati/`). |
|
|
| `images/`: Contains the input images for each site (i.e., Cornelia, Ahuna Mons, and Ikapati) in multiple formats. |
|
|
| - `*_calib.npy`: Radiometrically calibrated to units of reflectance (L/F). |
| - `*_uncalib.npy`: |
| - `*.png`: |
