Error code:   DatasetGenerationCastError
Exception:    DatasetGenerationCastError
Message:      An error occurred while generating the dataset

All the data files must have the same columns, but at some point there are 12 new columns ({'n_frames', 'boot95_high_pct', 'iqr_high_pct', 'iqr_low_pct', 'median_scale_err_pct', 'median_depth_m', 'median_planarity_mm', 'boot95_low_pct', 'depth_bin_m', 'median_tilt_deg', 'region', 'median_u_px'}) and 17 missing columns ({'t_s', 'planarity_rms_mm', 'plane_dist_m', 'frame', 'scale_err_x_pct', 'corners', 'session', 'recording', 'tilt_deg', 'scale_err_pct', 'u_px', 'r_px', 'v_px', 'depth_z_m', 'square_x_mm', 'square_y_mm', 'scale_err_y_pct'}).

This happened while the csv dataset builder was generating data using

ODL Stereo Depth-Scale Accuracy 25-90 cm

English technical note | Korean technical note

ODL Field Note #09 — Stereo depth-scale accuracy (25–90 cm)

Reproduction code and derived measurements for Origin Data Lab Technical Field Note #09.

What it measures

Stereo depth-scale error of a fisheye stereo+IMU rig (R8 OEM, ODL-EGO S1 configuration) against ChArUco squares measured with a steel rule.

Reproduce

pip install opencv-contrib-python-headless==4.10.0.84 numpy pandas pyyaml matplotlib
export ODL_DATA=analysis/data          # detection JSONs + factory_calibration.yaml
PYTHONPATH=analysis python3 analysis/a1_depth_scale.py out
PYTHONPATH=analysis python3 analysis/make_figures.py out

factory_calibration.yaml is manufacturer material and is not included; without it the triangulation step cannot be reproduced. Detection JSONs (corner coordinates) are included.

Outputs

file	content
a1_per_frame.csv	one row per stereo frame: distance, tilt, image position, square size, scale error
a1_scale_summary.csv	medians / IQR / bootstrap CI per distance bin and edge region
a1_tape_holds.csv	tape-measure holds vs stereo distance with linear fit

Limits

Single unit, single day, automated analysis only. See methodology.md.

Licence: to be decided (candidates: MIT for code, CC BY 4.0 for CSV) — not applied yet.
