1. 激光雷达硬件连接

1.1 工具准备

准备一套速腾聚创16线激光雷达
本文使用的PC系统是Ubuntu 1804系统，也使用Ubuntu 1604，Ubuntu 20.04；
准备AC 220V电源或DC 12V；

1.2 硬件连接

[1] 如下图所示，将雷达一端的航插头接口与雷达电源盒子的航插头接口两个，对准红点接好；

[2] 接上电源，接上网线，一端接入到PC，一端接入到电源盒子，如下图；

[3] 设置PC Ubuntu1804静态IP，速腾聚创16线激光雷达出厂默认发送到192.168.1.102，在连接前可以通过wireshark抓包工具进行检测；

！！！正常发送UDP数据流才算正常接入！！！

2. 激光雷达参数配置

从以上数据流可以看出，雷达的IP是192.168.1.200，PC的静态IP是192.168.1.102，端口分别是6699、7788；

如果需要修改这些信息，需要使用速腾聚创16线激光雷达的官方上位机，下载路径：https://www.robosense.ai/resources-27

本文不做解释！！

3. ROS驱动安装&&参数配置

[1] 使用Git下载驱动：https://github.com/RoboSense-LiDAR/rslidar_sdk

git clone https://github.com/RoboSense-LiDAR/rslidar_sdk.git
cd rslidar_sdk
git submodule init
git submodule update

[2] 安装Pcap

sudo apt-get install -y  libpcap-dev

[3] 参数配置，打开config.yaml，安装提示配置；

[4] 驱动直接编译

按照如下指令即可编译运行程序。直接编译也可以使用ROS相关功能(不包括ROS2)，但需要在程序启动前手动启动roscore，启动后手动打开rviz才能看到可视化点云结果。

cd rslidar_sdk
mkdir build && cd build
cmake .. && make -j4
./rslidar_sdk_node

4. rviz点云展示

显示点云如下
