Chamfer Distance

[artest08]

Hello,

In the issues, there is an indicated strong baseline. In that, chamfer distance is indicated as DET_l_chamfer. How is it calculated? Are thresholds again the same with Frechet Thresholds? Can we directly calculate it as below?

metrics['OpenLane-V2 Score']['DET_l_chamfer'] = _mAP_over_threshold(
    gts=gts, 
    preds=preds, 
    distance_matrixs=distance_matrixs['chamfer'], 
    distance_thresholds=THRESHOLDS_FRECHET,
    object_type='lane_centerline',
    filter=lambda _: True,
    inject=True, # save tp for eval on graph
).mean()

Thanks in advance

Hi, that is some obsolete code. For evaluation, please refer to the official evaluation kit.
