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：

1 https://github.com/ktossell

2 https://orbbec3d.com/develop/

也可以直接下载打包好的资源：

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：

~/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：

~$ sudo apt-get install ros-kinetic-astra-camera ros-kinetic-astra-launch

完毕后，使用：

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：

~$ roslaunch astra_launch astra.launch

使用rqt_image_view：

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。

~$ rosrun libuvc_camera camera_node

[ERROR] [1481169521.461465837]: Permission denied opening /dev/bus/usb/002/004

出现报错，修改端口权限，重试。

relaybotbox@relaybotbox-desktop:~$ sudo chmod 777 /dev/bus/usb/002/004

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。
