安装过程可能遇到的问题：

解决方案E: Unable to locate package ros-kinetic-rgbd-launch

roslaunch astra_camera astra.launch


rosrun camera_calibration cameracalibrator.py --size 12x9 --square 0.020 image:=/image_raw camera:=/camera --no-service-check

乐视体感astra pro深度摄像头在ros系统获取 深度图像 彩色图像 无色彩点云数据 彩色点云数据
1.Pull the repository into your ROS workspace

/catkin_ws/src
git clone https://github.com/orbbec/ros_astra_camera

Create astra udev rule

roscd astra_camera
./scripts/create_udev_rules

Go to catkin workspace and compile astra_camera

/catkin_ws
catkin_make --pkg astra_camera

若：

Could not find a package configuration file provided by "libuvc" with any of the following names:
libuvcConfig.cmake
libuvc-config.cmake

安装解决之：

sudo apt-get install ros-kinetic-uvc-camera

发布压缩图像话题需要安装插件：

sudo apt-get install ros-kinetic-image-* 

2.无法打开摄像头解决方法

[ INFO] [1485844378.430540517]: No matching device found.... waiting for devices. Reason: astra_wrapper::AstraDevice::AstraDevice(const string&) @ /home/dwikyerl/catkin_ws/src/ros_astra_camera/src/astra_device.cpp @ 76 : Device open failed

之前在两个x64的ubuntu下使用很正常，不知道nano上是为什么报错;
突然想起来好像没写udev/rules.d，就赶紧写了一下：

cd /etc/udev/rules.d/ sudo gedit 56-orbbec.rules
复制下面内容进去：

SUBSYSTEM=="usb", ATTR{idProduct}=="0400", ATTR{idVendor}=="2bc5", MODE:="0666", OWNER:="root", GROUP:="video"

SUBSYSTEM=="usb", ATTR{idProduct}=="040a", ATTR{idVendor}=="2bc5", MODE:="0666", OWNER:="root", GROUP:="video"

写完突然又发现openni没安装，赶紧

sudo apt-get install ros-kinetic-openni-*
和
sudo apt-get install ros-kinetic-opnenni2-*

再次驱动astra就没问题了！
重启udev

sudo service udev reload
sudo service udev restart

重插底盘和乐视的USB线
启用环境

source /opt/ros/kinetic/setup.bash

没有彩色图像

sudo apt-get install ros-kinetic-uvc-camera
sudo apt-get install ros-melodic-uvc-camera
sudo apt-get install v4l-utils
sudo v4l2-ctl --list-devices
