Is it possible to find out driveable area based on HD map in motion dataset?

Open TimHo0331 opened this issue 2 years ago • 5 comments

dear authors, thank you very much for releasing the data!

I want to find out the driveable area using the vector map provided in the motion dataset? (e.g. to see if a xy coordinate is in the driveable area) How can I do that? can you help me? Thank you so much!

We do not provide a direct way to compute driveable area. You will need to develop an algorithm for this. We do provide lane centers, lane boundaries, and road edges which also contain direction vectors that you can use for this purpose. Please let me know if you have further questions.

Hi @scott-ettinger,

May I know what types of map features constitute the boundary of the drivable area? Does it include 'ROAD_EDGE_UNKNOWN', 'ROAD_EDGE_BOUNDARY', and 'ROAD_EDGE_MEDIAN'? And what about the road line types?

Sorry for the late reply, I think it depends on how you define "drivable area". The road surface is defined by the TYPE_ROAD_EDGE_BOUNDARY and TYPE_ROAD_EDGE_MEDIAN features. The RoadLine features define where a vehicle is allowed to drive within that road surface. Please let me know if you have further questions.

Thanks for the reply.

In relation to this, I am trying to create a polygon of the road based on the waymo map in order to evaluate drivable area estimation algorimths. I am having a hard time doing so because the road boundaries are out of order. Any way I could streamline this process?
