1. 安装框架 hector_slam_example [https://github.com/DaikiMaekawa/hector_slam_example]
参考网址： http://m.blog.csdn.net/article/details?id=49026955
或 http://www.cnblogs.com/zxouxuewei/p/5307736.html ----- 二.利用深度相机仿激光数据创建地图
1.1 git clone
1.2 添加 clone 路径到 $ROS_PACKAGE_PATH
ROS_PACKAGE_PATH=/home/durant35/Workspace/ROS/hector_slam/hector_slam_example:$ROS_PACKAGE_PATH
1.3 安装
rosdep install hector_slam_example
2. 运行
2.1 确保 $ROS_PACKAGE_PATH 找到 hector_slam_example
ROS_PACKAGE_PATH=/home/durant35/Workspace/ROS/hector_slam/hector_slam_example:$ROS_PACKAGE_PATH
2.2 修改 clone 路径下的 launch 文件，这里修改 hector_hokuyo.launch，换成我们自定义的驱动 urg_node
<!-- Modified by Durant35, use another driver urg_node instead of hokuyo_node
<node pkg="hokuyo_node" type="hokuyo_node" name="hokuyo_node"/>
-->
<node pkg="urg_node" type="urg_node" name="urg_node">
<!-- Set the port to connect to here ethernet -->
<param name="ip_address" type="string" value="192.168.0.10"/>
</node>
注：param节点用于传参数，可有可无，因为默认就是 192.168.0.10
具体参数及参数类型，请查看驱动wiki说明
2.3 启动，运行，进入实验建图
roslaunch hector_slam_example hector_hokuyo.launch
2.4 如何解决没办法显示轨迹的问题
<!-- Modified by Durant35, for generating trajectory, follow
https://github.com/tu-darmstadt-ros-pkg/hector_slam/blob/catkin/hector_slam_launch/launch/tutorial.launch
<include file="$(find hector_geotiff)/launch/geotiff_mapper.launch"/>
-->
<include file="$(find hector_geotiff)/launch/geotiff_mapper.launch">
<arg name="trajectory_source_frame_name" value="scanmatcher_frame"/>
<arg name="map_file_path" value="$(arg geotiff_map_file_path)"/>
</include>

gmapping库需要两个输入，其一为激光雷达数据/scan，其二为全局的tf转换关系；且gmapping需求的tf中需要一个里程计数据以构建坐标系
