Carla学习笔记（二）服务器跑carla，本地运行carla-ros-bridge并用rviz显示

一、服务器跑carla

详见Carla学习笔记（一）服务器跑carla本地显示窗口_Zero_979的博客-CSDN博客

只需要启动服务器端就行：

./CarlaUE4.sh -carla-rpc-port=2000 -RenderOffScreen -graphicsadaper=1

二、本地下载 carla-ros-bridge

官方库：https://github.com/carla-simulator/ros-bridge

下载完后编译一下

具体操作：参考官方文档Install ROS Bridge for ROS 1 - CARLA Simulator

1. Create a catkin workspace:

    mkdir -p ~/carla-ros-bridge/catkin_ws/src

2. Clone the ROS Bridge repository and submodules:

    cd ~/carla-ros-bridgegit clone --recurse-submodules https://github.com/carla-simulator/ros-bridge.git catkin_ws/src/ros-bridge

5. Set up the ROS environment according to the ROS version you have installed:

    source /opt/ros/<melodic/noetic>/setup.bash

6. Install the required ros-dependencies:

    cd catkin_wsrosdep updaterosdep install --from-paths src --ignore-src -r

7. Build the ROS bridge:

    catkin build   # alternatively catkin_make

三、运行carla-ros-bridge里的demo

下载并且编译完成后，我们来启动运行：

 vi ~/carla-ros-bridge/catkin_ws/devel/setup.bash

然后在这个文件里添加两行：

export CARLA_ROOT=/你的路径/CARLA_0.9.13（也可能是其它版本）
export PYTHONPATH=$PYTHONPATH:$CARLA_ROOT/PythonAPI/carla/dist/carla-0.9.13-py3.7-linux-x86_64.egg（替换成你egg文件）:$CARLA_ROOT/PythonAPI/carla

进入到carla_ad_demo文件夹里，修改代码里的Host为你服务器的地址

source ~/carla-ros-bridge/catkin_ws/devel/setup.bash
roslaunch carla_ad_demo carla_ad_demo.launch

不出意外的话就会弹出窗口，按P进入自动驾驶模式。

 四、启动rviz

在~/catkin_ws/src/ros-bridge/carla_ad_demo/config下启动 rviz carla_ad_demo.rviz

点击左下角的add

 

就能看到camera成像啦！也可以自己加一些其他的监视。
