lanelet2anchors

This package enables the generation of diverse map-based anchor paths for a given lanelet or vehicle pose. It was developed as part of our paper Lanelet2 for nuScenes: Enabling Spatial Semantic Relationships and Diverse Map-based Anchor Paths. For details check our project page.

Installation

Use Python >= 3.8 and pip to install

pip install lanelet2anchors

Usage

Check the notebooks in the documentation for details and examples.

Generate anchors for given vehicle

from lanelet2anchors import AnchorGenerator

lanelet_map = AnchorGenerator(
    osm_file=osm_file, origin_latitude=49.00345654351, origin_longitude=8.42427590707
)

anchors = lanelet_map.create_anchors_for_vehicle(
    vehicle_pose=X,
    anchor_length=100,
    num_anchors: 5,
)

Generate anchors for a given Lanelet

from lanelet2anchors import AnchorGenerator

lanelet_map = AnchorGenerator(
    osm_file=osm_file, origin_latitude=49.00345654351, origin_longitude=8.42427590707
)

anchors = lanelet_map.create_anchors_for_lanelet(
    lanelet_id=lanelet_map.lanelet_ids[0], anchor_length=100
)
