compute laneiou

[zyk516]

Hello, according to https://github.com/hirotomusiker/CLRerNet/blob/main/configs/clrernet/base_clrernet.py#L53, iou_dynamick uses lane_width=7.5 / 800 and use_pred_start_end=False, but iou_cost uses lane_width=30 / 800 and use_pred_start_end=True.I want to know why they use different settings. Could you please explain it to me?

Thank you, we employ wider virtual width for the IoU cost just to balance with the classification cost. https://github.com/hirotomusiker/CLRerNet/blob/main/libs/core/bbox/assigners/dynamic_topk_assigner.py#L180
