如何进行OpenNI-Linux-Arm64-2.3.0.66安装与调试，很多新手对此不是很清楚，为了帮助大家解决这个难题，下面小编将为大家详细讲解，有这方面需求的人可以来学习下，希望你能有所收获。
最近在研究某摄像头，通过USB插入到Arm64的板子上进行安装调试，这里尝试着把过程记录下来。
从官网上下载相应系统和版本的SDK，我这里是Linux-ARM64版本的，下载的是 OpenNI-Linux-Arm64-2.3.0.66 。或者wget链接地址

阅读README文件，其中
0 OpenNI-Linux-Arm64-2.3.0.66 > cat README OpenNI ------ Website: http://structure.io/openni Building Prerequisites ====================== ... Linux ----- - GCC 4.x From: http://gcc.gnu.org/releases.html Or via apt: sudo apt-get install g++ - Python 2.6+/3.x From: http://www.python.org/download/ Or via apt: sudo apt-get install python - LibUSB 1.0.x From: http://sourceforge.net/projects/libusb/files/libusb-1.0/ Or via apt: sudo apt-get install libusb-1.0-0-dev - LibUDEV sudo apt-get install libudev-dev - JDK 6.0 From: http://www.oracle.com/technetwork/java/javase/downloads/jdk-6u32-downloads-1594644.html Or via apt: sudo apt-get install openjdk-6-jdk - FreeGLUT3 From: http://freeglut.sourceforge.net/index.php#download Or via apt: sudo apt-get install freeglut3-dev - Doxygen From: http://www.stack.nl/~dimitri/doxygen/download.html#latestsrc Or via apt: sudo apt-get install doxygen - GraphViz From: http://www.graphviz.org/Download_linux_ubuntu.php Or via apt: sudo apt-get install graphviz ... Building ======== Building on Windows: Open the solution OpenNI.sln Building on Linux / OS X: Run: $ make Cross-Compiling for ARM on Linux: The following environment variables should be defined: - ARM_CXX=<path to cross-compilation g++> - ARM_STAGING=<path to cross-compilation staging dir> Then, run: $ PLATFORM=Arm make Building for Android: - Create a workspace in eclipse - Import all projects under root directory Creating OpenNI2 Package ======================== - Go into the directory 'Packaging' - Run ReleaseVersion.py [x86|x64|Arm|Android] - Installer will be placed in the 'Final' directory Building in an armhf qemu-enabled docker container ================================================== - Note: we're building from the osrf fork which has a couple of minor tweaks compared to the orbbec upstream repo (https://github.com/orbbec/OpenNI2/compare/orbbec-dev...osrf:orbbec-dev?expand=1): - don't force soft-float in third-party software (because we're building with hard-float) - disable documentation generation (because we don't need it, and also because doxygen seems to just hang in this environment). - Check out the code (because git doesn't work inside qemu): $ git clone https://github.com/osrf/OpenNI2 $ cd OpenNI2 $ git checkout orbbec-dev $ cd .. - Start docker, mounting in the git repo: $ docker run -ti -v `pwd`/OpenNI2:/tmp/OpenNI2 osrf/ubuntu_armhf:trusty bash - Now inside docker, install prereqs (we're removing udev because it somehow conflicts with libudev-dev; we're leaving out doxygen and graphviz because we're not going to build docs): # apt-get update # apt-get remove -y --force-yes udev # apt-get install -y build-essential python libusb-1.0-0-dev libudev-dev openjdk-6-jdk freeglut3-dev - Still inside docker, build the release package (note that, instead of running `ReleaseVersion.py` inside `Packaging`, you could just run `make HAS_JAVA=1 release` at the top level): # cd /tmp/OpenNI2/Packaging # ./ReleaseVersion.py Arm - If all goes well, there will be a file in the docker container called something like `/tmp/OpenNI2/Packaging/Final/OpenNI-Linux-Arm-2.3.tar.bz2`. It's also in the corresponding place in the host filesystem, so it will survive exiting the container. That file contains the compiled libraries (importantly, `OpenNI-Linux-Arm-2.3/Redist/libOpenNI2.so`).
这里指明了一些软件运行所需的依赖和安装方法，这里就不再赘述。后续的 building 等不是必须的操作。
在解压后的目录中，执行 install.sh 文件
sudo sh install.sh
该脚本一共做了两件事，为摄像头设备增加UDEV规则，把开发环境写到 OpenNIDevEnvironment文件中。
cat OpenNIDevEnvironment export OPENNI2_INCLUDE=/home/work/abc/OpenNI-Linux-Arm64-2.3.0.65/Include export OPENNI2_REDIST=/home/work/abc/OpenNI-Linux-Arm64-2.3.0.65/Redist
注意第一个环境变量的Include，实际的目录名称为 include，记得改过来（要么把目录名称改成大写，要么把环境变量改成小写，我这里是选择改环境变量。）
然后再进行加载使其生效。
source OpenNIDevEnvironment
检查一下
env | grep OPENNI2_INCLUDE OPENNI2_INCLUDE=/home/work/abc/OpenNI-Linux-Arm64-2.3.0.66/include
在Samples目录下，我们可以看到很多样例
drwxrwxr-x 3 work work 4096 Jan 20 22:10 Bin drwxrwxr-x 2 work work 4096 Jan 20 22:10 ClosestPointViewer drwxrwxr-x 2 work work 4096 Jan 20 22:10 EventBasedRead drwxrwxr-x 2 work work 4096 Jan 20 22:10 MWClosestPoint drwxrwxr-x 2 work work 4096 Jan 20 22:10 MWClosestPointApp drwxrwxr-x 2 work work 4096 Jan 20 22:10 MultiDepthViewer drwxrwxr-x 3 work work 4096 Feb 8 17:28 MultipleStreamRead drwxrwxr-x 3 work work 4096 Jan 21 20:06 SimpleRead drwxrwxr-x 3 work work 4096 Jan 27 10:59 SimpleViewer drwxrwxr-x 3 work work 4096 Jan 20 22:10 SimpleViewer.java
我们就以SimpleRead为例，来测试一下。进入目录，结构如下：

把 INC_DIRS 中的 ../../Include \ 改成实际的 ../../include \，而 ../Common 目录其实并不存在，也可以注释掉。

}其实是将镜头中心的点所获取到的深度信息不断地进行输出。

可以看到，这里就输出了深度信息。
至此，我们就把OpenNI在Linux/Ubuntu16.04-Arm64上安装成功了。
