简易场景下的路径规划

Global planner: A* (carla_ros_bridge 自带)

Local planner: Lattice Planner、EM Planner

Build

1.安装依赖：

• Ubuntu 18.04/20.04

• ROS Melodic/Noetic

• Eigen

• cmake >= 3.5

• python3.X

• Carla simulator (0.9.11)

  安装配置手册：https://carla.readthedocs.io/en/latest/start_quickstart/

• ROS bridge for CARLA simulator(0.9.11)

  安装配置手册：https://carla.readthedocs.io/projects/ros-bridge/en/latest/ros_installation_ros1/

• Carla scenario_runner(0.9.11)

​ 安装配置手册：https://carla-scenariorunner.readthedocs.io/en/latest/getting_scenariorunner/

2. 配置工作空间

快速配置方式：

cd scripts
./quickly_setup.sh

手动配置方式：

1.创建src文件，放置功能包源码：
  mkdir -p ~/catkin_ws/src

2.进入src文件夹
  cd ~/catkin_ws/src

3.将功能包复制到的src目录下

4.初始化文件夹
  catkin_init_workspace

5.编译工作空间
  catkin build
  
  #catkin build -DCMAKE_BUILD_TYPE=Debug  #for debug

Run Controller Demo
