Input: OpenLABEL (expected structure)

COSMO reads OpenLABEL JSON and extracts object metadata and per-frame rotated bounding boxes (rbbox).

Required content

COSMO expects, per frame, objects that contain an rbbox with at least five values:

[cx, cy, w_px, h_px, yaw] in pixel coordinates.

COSMO looks for rbbox values under:

• openlabel.frames[*].objects[*].object_data.rbbox.val, or
• ...rbbox.shape.val (supported variant)

Optional object metadata

If present under openlabel.objects, COSMO uses:

• type (e.g., car, truck, pedestrian)
• optional subtype and role (mapped to OSI-like naming/codes when possible)

Confidence

COSMO can read confidence from: object_data.vec.confidence.val (if present).
