您好，在超大路口时，路口远端可能会超出BEV空间的建模距离，在当前的问题定义下，退出车道是不会在GT或Pred中表示完全的。
在一定程度上，BEV检测模型可以模糊地从图像中捕捉到较远处路口的特征，因此路口内的虚拟连接线还是有迹可循的，但预测准确度会受到一定影响。在这种情况下，长距离、大范围的BEV检测还有待探索。
另外，您所提到的遮挡问题，可以通过时序模型或补全模型来在一定程度上得到缓解。

感谢您的回复！目前在大型路口的长距离、大范围的BEV检测确实是一个还在成长的问题，或许不同焦段的相机传感器能够起到一些作用。还有关于遮挡的问题，使用补全模型真的是一个很有意思的点！会持续关注您后面的工作的，手动点赞👍
