| # Sample inputs shipped with meteor-p150 |

|
| Only REDISTRIBUTABLE data goes here (Apache-2.0 / MIT / CC-BY with attribution). Data whose license is unstated or |
| non-commercial (the Autoware demo rosbag, nuScenes, Argoverse 2, ...) is NOT shipped: `code/scripts/fetch_samples.sh` |
| downloads it (sha256-checked) for the tests and benchmarks. |
|
|
| Never use the `.bin` suffix here (or `.pt`, `.pth`, `.ckpt`, `.safetensors`): tt-model's staging silently drops |
| those suffixes from `code/` (`CODE_IGNORE`, tt-model-manager `src/tt_kernel/build.py:328-332`). Store point clouds as |
| `.npy` / `.npz` / `.pcd`. |
|
|
| Next to each sample, `<stem>.reference.json` is the `/predict` body of the fp32 CPU reference (`tt_meteor.reference`, |
| `Output.to_dict()`) on it; `server/smoke_test.py` compares the served output with it (the smoke gate for synthetic |
| samples, which may give no detections). When the output depends on the serve profile or the model variant, store |
| one per profile or variant as `<stem>.<profile>.reference.json` / `<stem>.<variant>.reference.json`. Regenerate it |
| whenever the reference, the weights or the post-processing changes. |

| | `synthetic_8cam.json` | the request manifest: the eight camera PNGs (all present), calibration preset `synthetic_8cam`, `ego_speed` 8.0 m/s, stream id + ego pose; `tt_meteor.load_sample(path)` -> `model(**kwargs)`; `server/client.py --sample` / `server/smoke_test.py` build the `/predict` body from it | generated by `code/scripts/make_synthetic_sample.py` | Apache-2.0 (data generated by this repository) | |
| | `synthetic_8cam/<CAM>.png` | eight 768x432 RGB images (lossless PNG, 1.4 MB in total): a ray-cast street (a straight two-lane road with lane lines, a stop line and a zebra crossing, kerbs, pavements, facades, box-shaped vehicles and pedestrians) seen by a generic METEOR-like rig; the pixels of the objects (only those) were then optimised against the fp32 CPU reference (gradient ascent through the image encoder, the lift, the BEV detector and the box refiner, 88 steps) until the 3D heads report six vehicles and two pedestrians with large margins (scores 0.889-0.993 against the thresholds 0.35 / 0.15) and nothing else (strongest other heatmap cell 0.179 vehicle / 0.072 VRU), so bf16 numerics cannot flip a published box. A test pattern, not a photograph: the objects carry noisy texture | as above | Apache-2.0 | |
| | `synthetic_8cam.reference.json` | the `/predict` body of the fp32 CPU reference (`tt_meteor.reference.pipeline.MeteorReference`, PCC 1.0 vs ONNX Runtime) on the request above as a fresh stream (`timing_ms` emptied): 8 boxes (6 VEHICLE, 2 VRU), 10 2D boxes, plan mode 0 (the car ahead and a red light: the selected path brakes), traffic light red; `server/smoke_test.py` (the container smoke, `--expect VEHICLE:6,VRU:2` by default) and `tests/test_e2e_device.py` compare the served body with it | `code/scripts/make_synthetic_sample.py finalise` | Apache-2.0 | |
|
|
| The calibration preset `../calib/synthetic_8cam.json` is the same generated rig (round numbers of our own: METEOR's |
| slot layout, 98 deg wide cameras front and back, corner cameras pitched 25 deg down, 30.4 deg narrow cameras, fy = |
| 0.87 fx like METEOR's vertically squashed training images, 1.9 m above the road). |
|
|
| A real-world sample (PandaSet 019 frame 40, CC BY 4.0 + PandaSet Dataset Terms, METEOR's 8-slot layout) is prepared |
| but **not shipped** until the redistribution of PandaSet-derived samples is approved; the device tests read it from |
| the git-ignored `staging_samples_pandaset/` of the development checkout (`tests/paths.py`). METEOR's own demo scenes |
| (`AutowareFoundation/meteor-demo-scenes`, research / demonstration use only) and nuScenes (CC BY-NC-SA 4.0) are never |
| shipped: `code/scripts/fetch_samples.sh` notes where to fetch them. |
