PricoEye: The Eye of Primary Colors for Fast and Convenient 3D Reconstruction of Fine-grained Pal...
summary
An ultra‑compact add‑on under 3 mm thick and under $2 attaches to a smartphone camera, flashes PCB LEDs in time‑division or frequency‑division multiplexing to simulate multi‑angle illumination, and uses photometric stereo to recover fine ridges as 3D normals. Implementation captures three key frames in a single shot with FDM, reconstructs against 100 high‑precision 3D‑printed fingerprint films with low Hausdorff distance, outperforms RGB baselines on palm recognition, and notes limitations for specular/greasy skin.
