Dear author,

I noticed that you have addressed several times already, but I still find it a bit unclear. I notice that in your work bev_h is 50 and bev_w is 100. I assume this means that the vehicle is facing the positive X axis. But what about the positive Y axis? Does that mean the leftward direction of the vehicle? Or after you flip the Y axis, actually downward means leftward?

Yes, I think you've almost got it. The positive X-axis points rightward on BEV feature space (and the vehicle is facing positive X-axis too). The positive Y-axis points upward on BEV, which means the lefthand side of the vehicle.

@yuantianyuan01 Can you explain why there is a minus in this part? https://github.com/yuantianyuan01/StreamMapNet/blob/000ce22f2fae6a1798a57471f820b8232ae76a74/plugin/models/mapers/StreamMapNet.py#L135 may be there smt to do with this line but I don't understand why did you do that: https://github.com/yuantianyuan01/StreamMapNet/blob/000ce22f2fae6a1798a57471f820b8232ae76a74/plugin/models/mapers/StreamMapNet.py#L66
