Ubuntu下安装RealSense的Ros包
Ubuntu下安装RealSense的Ros包
1.介绍
准备工作：
首先需要在Ubuntu中安装Ros(Ubuntu16.04对应的Ros版本为ROS Kinetic)，关于Ubuntu下Ros的安装大家可参考下面网址：
- http://wiki.ros.org/kinetic/Installation/Ubuntu
- https://blog.csdn.net/shijiegong123/article/details/103082119
2.安装RealSense的Ros包
Install Intel® RealSense™ ROS from Sources
Create a catkin workspace
-
$mkdir -p ~/catkin_ws/src
-
$cd ~/catkin_ws/src/
-
Clone the latest Intel® RealSense™ ROS from here into
catkin_ws/src/
https://github.com/IntelRealSense/realsense-ros/releases -
$catkin_init_workspace
-
$cd .. -
$catkin_make clean
-
$catkin_make -DCATKIN_ENABLE_TESTING=False -DCMAKE_BUILD_TYPE=Release
-
$catkin_make install
$echo "source ~/catkin_ws/devel/setup.bash" >> ~/.bashrc
- $source ~/.bashrc
若编译时出现
realsense2_camera/src/base_realsense_node.cpp:363:14: error: ‘class ddynamic_reconfigure::DDynamicReconfigure’ has no member named ‘publishServicesTopics’ ddynrec->publishServicesTopics();
原因：
IntelRealSense-Ros上缺少DDynamic_reconfigure（被intel删掉了），因此需要安装DDynamic_reconfigure
解决办法：
-
sudo apt-get install ros-kinetic-ddynamic_reconfigure （没有效果）
-
需要进入
https://github.com/pal-robotics/ddynamic_reconfigure 下载源码DDynamic_reconfigure，将源码放到catkin_ws/src/下再重新catkin_make
3.使用
安装好RealSense的Ros包后，打开终端使用下面指令查看
$roslaunch realsense2_camera rs_rgbd.launch(或者roslaunch realsense2_camera rs_camera.launch)
$rostopic echo /camera/color/camera_info
4.问题
