Data for LookUp3D: Data-Driven 3D Scanning

This deposit contains captured and processed data for LookUp3D, a novel calibration and reconstruction procedure for structured light scanning that foregoes explicit point triangulation in favor of a data-driven lookup procedure. The key idea is to sweep a calibration checkerboard over the entire scanning volume with a linear stage and acquire a dense stack of images to build a per-pixel lookup table from colors to depths. Imperfections in the setup, lens distortion, and sensor defects are baked into the calibration data, leading to a more reliable and accurate reconstruction.

Captured data is provided in TIFF or JPEG file formats, along with the calibrated lookup table files in numpy-specific file formats and a JSON configuration file. Processed data is provided as point clouds (ASCII .ply files) corresponding to figures presented in the paper (plus additional examples) and OBJ (.obj) files used to measure error.
