Stationary-start TUV test clips

This dataset contains 86 clips with verified zero-speed starts and requested event durations below 35 seconds, plus one explicitly selected 35-second CCRb clip, across CCRs (stationary target), CCRm (moving target), and CCRb (braking target).

CCRs: 31, CCRm: 50, CCRb: 5

Read clips.csv to select a clip by scenario, speed, or duration. All paths in the manifest are relative to this dataset root. files.csv lists each payload file and byte size. The test split is an organizational choice; no train/test independence claim is made.

The folder name is the clip UUID, with --IVEX appended for shortlisted clips; the source event and recording session UUIDs are separate columns in clips.csv. Start/end values are PTP microseconds. Duration is (end_ptp_us - start_ptp_us) / 1e6. Sensor extraction can include format/index boundary data; use timestamps and seek indexes when reading.

last.usdz contains the complete packaged reconstruction. The USD scene, checkpoint, trajectory/tracks, configuration, and other available assets remain inside the USDZ. Extract the bundle locally only if your tools require individual files. Not every reconstruction has identical optional assets. A compatible NuRec renderer is needed for neural rendering; a generic USD viewer may not render the neural appearance. Radar and RC logs require compatible decoding tools and are not CSV tables.

Ground truth and limitations

GT CSVs retain their original columns and units (the second CSV row contains units). _window.csv preserves only available recorded samples within an estimated clock-aligned interval; it is not extrapolated to fill the clip. Alignment uses speed traces, not an exact hardware clock calibration. Read alignment.json and manifest gt_missing_start_s / gt_missing_end_s before comparing trajectories. Having a matched GT CSV does not guarantee full stationary-window coverage or prove trajectory agreement.

Stationary refers to ego speed at the requested event start. It does not mean the entire scene or target remains stationary. The reconstructed camera sequence can have a slightly narrower frame-available window than the requested recording interval.

Inclusion requires NuRec, recorded RC log, all five radar bins, with GT where a confident match exists. Five selected clips have missing GT; these are flagged by gt_status=missing, an empty gt_window_path, and ground_truth/MISSING_GT.txt. Do not treat them as ground-truth-evaluated clips. Clips missing NuRec or verified recordings are excluded until those artifacts are available. This selection is not a claim of KPI success or visual quality. No PSNR values are supplied; the upstream PSNR computation was unavailable. Perception-agreement failures do not establish missing rendered obstacles.

IVEX shortlist

Folders ending in --IVEX identify the 15 executive-review selections. The additional CCRb clip 8fc7e6c9-e4df-41a8-b11f-c2d650c4f53e is a verified 35-second exception.
