+# 3D Object Detection Submission Format
+
+The evaluation expects the following fields within a `pandas.DataFrame`:
+
+- `tx_m`: x-component of the object translation in the egovehicle reference frame.
+- `ty_m`: y-component of the object translation in the egovehicle reference frame.
+- `tz_m`: z-component of the object translation in the egovehicle reference frame.
+- `length_m`: Object extent along the x-axis in meters.
+- `width_m`: Object extent along the y-axis in meters.
+- `height_m`: Object extent along the z-axis in meters.
+- `qw`: Real quaternion coefficient.
+- `qx`: First quaternion coefficient.
+- `qy`: Second quaternion coefficient.
+- `qz`: Third quaternion coefficient.
+- `score`: Object confidence.
+- `log_id`: Log id associated with the detection.
+- `timestamp_ns`: Timestamp associated with the detection.
+- `category`: Object category.
+
+An example looks like this:
+
+```python
+# These detections are only for example purposes.
+
+display(detections)  # Detections is type `pd.DataFrame`

+We need to export the above dataframe for submission. This can be done by:

+```python
+import pandas as pd

+detections.to_feather("detections.feather")
+```
+
+Lastly, submit this file to the competition leaderboard.
