hokuyo激光雷达跑Cartographer
在安装好Cartographer和hokuyo激光雷达之后，我们就可以开始用激光雷达跑了。
本文部分参考博客https://www.cnblogs.com/wenhust/p/6047258.html，但本文安装的是谷歌源码cartographer，lua文件中的变量名字目前是最新的。
一、建立相关文件
1、首先在catkin_google_ws/src/cartographer_ros/cartographer_ros/launch文件夹下建立launch文件demo_hokuyo.launch
2、然后在catkin_google_ws/src/cartographer_ros/cartographer_ros/configuration_files下建立lua配置文件demo_hokuyo.lua
include "map_builder.lua"
include "trajectory_builder.lua"
options = {
map_builder = MAP_BUILDER,
trajectory_builder = TRAJECTORY_BUILDER,
map_frame = "map",
tracking_frame = "laser",
published_frame = "laser",
odom_frame = "odom",
provide_odom_frame = false,
use_odometry = false,
use_nav_sat = false,
use_landmarks = false,
publish_frame_projected_to_2d = false,
num_laser_scans = 1,
num_multi_echo_laser_scans = 0,
lookup_transform_timeout_sec = 0.2,
submap_publish_period_sec = 0.3,
pose_publish_period_sec = 5e-3,
num_subdivisions_per_laser_scan = 1,
num_point_clouds = 0,
lookup_transform_timeout_sec = 0.2,
submap_publish_period_sec = 0.3,
pose_publish_period_sec = 5e-3,
trajectory_publish_period_sec = 30e-3,
rangefinder_sampling_ratio = 1.,
odometry_sampling_ratio = 1.,
fixed_frame_pose_sampling_ratio = 1.,
imu_sampling_ratio = 1.,
landmarks_sampling_ratio = 1.,
}
MAP_BUILDER.use_trajectory_builder_2d = true
TRAJECTORY_BUILDER_2D.use_imu_data = false
TRAJECTORY_BUILDER_2D.use_online_correlative_scan_matching = true
POSE_GRAPH.optimization_problem.huber_scale = 1e2
return options
3、最后在该文件夹下建立rviz配置文件demo_hokuyo.rviz

二、开始建图
roscore//启动roscore
rosrun urg_ne urg_node _ip_address:=192.168.0.10//启动UST-20LX激光雷达
roslaunch cartographer_ros demo_hokuyo.launch//启动demo_hokuyo.launch
接下来就可以移动激光雷达去建图了！
