OpenDRIVE 2 Lanelets - Converter

This repository provides the code for an OpenDRIVE (www.opendrive.org) to lanelets (www.mrt.kit.edu/software/liblanelet) converter.

Installation

The following python packages have to be available:

numpy
scipy
lxml
matplotlib (only for GUI)
PyQt5 (only for GUI)

If needed, the converter libraries can be installed using pip:

git clone https://gitlab.lrz.de/koschi/converter.git
cd converter && pip install .

Example OpenDRIVE Files

Download example files from: http://opendrive.org/download.html

Usage

Using our provided GUI

Additional requirement: PyQt5. Start the GUI with python gui.py

Using the library in your own scripts

from lxml import etree
from opendriveparser import parse_opendrive
from opendrive2lanelet import Network

# Import, parse and convert OpenDRIVE file
fh = open("input_opendrive.xodr", 'r')
openDrive = parse_opendrive(etree.parse(fh).getroot())
fh.close()

roadNetwork = Network()
roadNetwork.loadOpenDrive(openDrive)

scenario = roadNetwork.exportCommonRoadScenario()

# Write CommonRoad scenario to file
fh = open("output_commonroad_file.xml", "wb")
fh.write(scenario.export_to_string())
fh.close()

Known Problems

When trying to use the gui.py under Wayland, the following error occurs:

This application failed to start because it could not find or load the Qt platform plugin "wayland" in "".
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.
Reinstalling the application may fix this problem.

Set the platform to xcb using this command: export QT_QPA_PLATFORM="xcb"

ToDo

CommonRoad does not support lane types right now. When this is implemented, the OpenDRIVE types have to be mapped onto the CommonRoad ones and added to the lanelet output.
Adjacent lanes are not working properly yet, support is not included in software right now.
Lane merges may cause problems with predecessor or successor definition.
