argoverse2 question #45

Open PeggyPeppa opened 1 year ago

PeggyPeppa commented 1 year ago

The lanesegments in the argoverse2 map are broken into several pieces. How do you deal with this problem?

LegendBC commented 1 year ago

we merge pieces into instance here

PeggyPeppa commented 1 year ago

Got it! But this part of code seems not consider the intersection's（in argoverse2, the linesegment has key "is_intersection"） influence. Only considering all linesegments are the same type and then use shapley api to conduct merging?

LegendBC commented 1 year ago

Intersection's lanesegments (None type lanemark) are not the divider defined in HDMapNet, so we have not included them in data preprocessing.

Thanks!

Besides can this method deal with the merge or split of lines?

LegendBC commented 1 year ago

You can refer to another project https://github.com/hustvl/LaneGAP to deal with lane graph especially.
