Orbbec Astra Pro传感器在ROS（indigo和kinetic）使用说明 rgb depth同时显示
这款摄像头使用uvc输入彩色信息，需要libuvc和libuvc_ros这样才能在ROS正常使用彩色功能。
请在下面网址，分别下载对应包：

首先安装驱动，依据版本选择下载驱动中合适的版本：
依据下列文档说明进行安装：特别注意标出部分
#############Note################### # For user with ARM based development board: # With CPU Structure older than Cortex A17, use OpenNI-Linux-Arm-2.3 Nofilter.tar for better performance #################################### # There are two zip files, one is for 32bit machine, the other one is for 64bit # We choose 64bit(x64) and make the example as follows: 这里应为系统是Ubuntu 16.04 64bit PC选择对应64bit版本 # To run visual samples(e.g., SimpleViewer), you will need freeglut3 header and libaries, please install:
$ sudo apt-get install build-essential freeglut3 freeglut3-dev
#check udev version, Orbbec Driver need libudev.so.1, if can't find it, can make symbolic link from libudev.so.x.x, #which usually locate in /lib/x86_64-linux-gnu or /lib/i386-linux-gnu
$ldconfig -p | grep libudev.so.1 $cd /lib/x86_64-linux-gnu $sudo ln -s libudev.so.x.x.x libudev.so.1 # copy tgz file to any place you want(e.g., Home) # unzip tgz file
拷贝到对应文件夹并解压缩：
$ tar zxvf OpenNI-Linux-x64-2.2-0118.tgz $ cd OpenNI-Linux-x64-2.2
# run install.sh to generate OpenNIDevEnvironment, which contains OpenNI development environment
$ sudo ./install.sh # please replug in the device for usb-register # add environment variables
$ source OpenNIDevEnvironment # build sample(e.g., SimpleViewer) $ cd Samples/SimpleViewer $ make # run sample # connect sensor $ cd Bin/x64-Release $ ./SimpleViewer
# now you should be able to see a GUI window showing the depth stream video # If the Debian Jessie Lite is used for testing, it may require the following installation for properly start the viewer.
$ sudo apt-get install libgl1-mesa-dri
安装完毕后，进行功能测试：
[html] view plain copy print ? ~/tools/OpenNI-Linux-x64-2.3/Samples/Bin$ ls ClosestPointViewer MultiDepthViewer org.openni.jar EventBasedRead MultipleStreamRead org.openni.Samples.SimpleViewer libMWClosestPoint.so MWClosestPointApp org.openni.Samples.SimpleViewer.jar libOpenNI2.jni.so OpenNI2 SimpleRead libOpenNI2.so OpenNI.ini SimpleViewer
使用./SimpleViewer和./ClosestPointViewer，注意传感器特性，深度视觉0.4-8.0米，如下：
安装ROS功能包，以kinetic为例，indigo类似：
[html] view plain copy print ? ~$ sudo apt-get install ros-kinetic-astra-camera ros-kinetic-astra-launch
完毕后，使用：
[html] view plain copy print ? relaybotbox@relaybotbox-desktop:~$ roslaunch astra_launch astra.launch device.launch pointclouds.launch astra_tf_prefix.launch ir.launch processing.launch color.launch kinect_frames.launch depth.launch manager.launch relaybotbox@relaybotbox-desktop:~$ roslaunch astra_launch astra.launch
工作正常的话可以看到：

发现rgb并没有正确显示？？需要UVC支持。
编译libuvc过程如下：注意红色部分
`libuvc` is a cross-platform library for USB video devices, built atop `libusb`. It enables fine-grained control over USB video devices exporting the standard USB Video Class (UVC) interface, enabling developers to write drivers for previously unsupported devices, or just access UVC devices in a generic fashion. ## Getting and Building libuvc Prerequisites: You will need `libusb` and [CMake](http://www.cmake.org/) installed. To build, you can just run these shell commands: Git clone https://github.com/ktossell/libuvc cd libuvc mkdir build cd build cmake .. make && sudo make install
and you're set! If you want to change the build configuration, you can edit `CMakeCache.txt` in the build directory, or use a CMake GUI to make the desired changes.
## Developing with libuvc
The documentation for `libuvc` can currently be found at https://int80k.com/libuvc/doc/.
然后编译libuvc_ros：注意红色部分
`libuvc_camera` is a ROS driver that supports webcams and other UVC-standards-compliant video devices. It's a cross-platform replacement for `uvc_camera`, a Linux-only webcam driver. Documentation is available on the ROS wiki: [libuvc_camera](http://wiki.ros.org/libuvc_camera).
使用catkin_make，如果报错，注意libusb.h的位置。使用locate libusb.h，并将其放到合适位置：
~$ sudo cp /usr/include/libusb-1.0/libusb.h /usr/local/include/libuvc/
修改下libuvc.h中include中的路径。
在启动roscore后，使用：
~$ rosrun libuvc_camera camera_node
查看rgb。

出现报错，修改端口权限，重试。

使用 rqt_image_view ，查看rgb如下：
同时使用也是可以的。
安装配置完毕，可以开始使用这款视觉传感器了。
