【开箱评测三】用RPLIDAR A2搭建hector_mapping |
本帖最后由 SLAMTEC 于 2016-12-28 15:01 编辑 1. 安装RPLIDAR包 建立catkin工作空间,在其src目录下git包: git clone https://github.com/robopeak/rplidar_ros 返回工作空间 catkin_make编译 2. 下载安装hector_mapping sudo apt-get install ros-indigo-hector-slam 3. 在rplidar_ros/launch/目录下添加 hector_mapping_demo.launch文件 文件如下: <launch> <node pkg="hector_mapping" type="hector_mapping" name="hector_mapping" output="screen"> <!-- Frame names --> <param name="pub_map_odom_transform" value="true"/> <param name="map_frame" value="map" /> <param name="base_frame" value="base_link" /> <param name="odom_frame" value="base_link" /> <!-- Tf use --> <param name="use_tf_scan_transformation" value="true"/> <param name="use_tf_pose_start_estimate" value="false"/> <!-- Map size / start point --> <param name="map_resolution" value="0.05"/> <param name="map_size" value="2048"/> <param name="map_start_x" value="0.5"/> <param name="map_start_y" value="0.5" /> <param name="laser_z_min_value" value = "-1.0" /> <param name="laser_z_max_value" value = "1.0" /> <param name="map_multi_res_levels" value="2" /> <param name="map_pub_period" value="2" /> <param name="laser_min_dist" value="0.4" /> <param name="laser_max_dist" value="5.5" /> <param name="output_timing" value="false" /> <param name="pub_map_scanmatch_transform" value="true" /> <!--<param name="tf_map_scanmatch_transform_frame_name" value="scanmatcher_frame" />--> <!-- Map update parameters --> <param name="update_factor_free" value="0.4"/> <param name="update_factor_occupied" value="0.7" /> <param name="map_update_distance_thresh" value="0.2"/> <param name="map_update_angle_thresh" value="0.06" /> <!-- Advertising config --> <param name="advertise_map_service" value="true"/> <param name="scan_subscriber_queue_size" value="5"/> <param name="scan_topic" value="scan"/> </node> <node pkg="rplidar_ros" type="rplidarNode" name="rplidarNode" output="screen"> <param name="serial_port" type="string" value="/dev/ttyUSB0"/> <param name="serial_baudrate" type="int" value="115200"/> <param name="frame_id" type="string" value="laser"/> <param name="inverted" type="bool" value="false"/> <param name="angle_compensate" type="bool" value="true"/> </node> <node pkg="tf" type="static_transform_publisher" name="base_to_laser_broadcaster" args="0 0 0 0 0 0 /base_link /laser 100"/> <node pkg="rviz" type="rviz" name="rviz" args="-d $(find hector_slam_launch)/rviz_cfg/mapping_demo.rviz"/> </launch> 运行这个launch文件,可以使用hector_mapping建地图。 如下图所示 要注意hector_mapping是不带里程计的,手拿着都可以建地图。 本文作者:Steven.Zhang (欢迎关注:http://www.rosclub.cn/) |
