篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了安装了kinect和OpenNI 2，kinect可正常启动，但使用NiViewer,显示不出图像，画面是一片空白。求解！相关的知识，希望对你有一定的参考价值。

按照网上的教程顺利安装kinect和OpenNI2，测试kinect已经可以显示出彩色图和深度图。测试OpenNI2的NiViewer却无法显示出任何图像，画面一片空白。OpenNI2-Samples-SimpleViewer也显示的一片空白，OpenNI2-Samples-SimpleReader却能看到数据的变化。将OpenNI2重新安装了无数次，结果都是一样的。这是为什么呢？请大侠们帮帮忙！

参考技术A 更新显卡驱动参考技术B 请问楼主的问题解决了么？参考技术C 我碰到一样的问题了，请问楼主解决了吗？求回复

ubuntu14.04 PCL1.8 OPENNI2.0 OPENCV3.0安装小结

最近入手NvidiaTegra 1 开发板，ARM架构的，做室内三维重建用。今天就讲讲的PCL 1.8+ OPENCV3.1 + OPENNI2.0在ubuntu14.04 上的安装与编译。

更新ubuntu的armhf源，修改source.list，中科大的快！

一、 Opencv

这个网上有很多教程，

1. 安装依赖包和预备环境

$sudo apt-get install build-essential
$sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
$sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev

2.从官网下载opencv3.1源码，并解压

3.创建编译目录，编译

$cd ~/opencv-3.1.0
$mkdir release
$cd release
$cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
$make
$sudo make install

4.测试opencv

$mkdir ~/opencv-lena
$cd ~/opencv-lena
$gedit DisplayImage.cpp

#include <stdio.h>
#include <opencv2/opencv.hpp>
using namespace cv;
int main(int argc, char** argv )
{
  if ( argc != 2 )
  {
    printf("usage: DisplayImage.out <Image_Path>\n");
    return -1;
  }
  Mat image;
  image = imread( argv[1], 1 );
  if ( !image.data )
  {
    printf("No image data \n");
    return -1;
  }
  namedWindow("Display Image", WINDOW_AUTOSIZE );
  imshow("Display Image", image);
  waitKey(0);
  return 0;
}

创建cmakelist编译文件

cmake_minimum_required(VERSION 2.8)
project( DisplayImage )
find_package( OpenCV REQUIRED )
add_executable( DisplayImage DisplayImage.cpp )
target_link_libraries( DisplayImage ${OpenCV_LIBS} )

执行：

$cd ~/opencv-lena
$cmake .
$make

$./DisplayImage lena.jpg

至此opencv配置完毕

二、openni2.0

以下内容是我在youtube上看到的视频：

https://www.youtube.com/watch?v=Bn9WqbYtNBw

1.安装 OpenNI2依赖项

$sudo apt-get install -y g++ python libusb-1.0-0-dev freeglut3-dev doxygen graphviz
$sudo apt-get install libudev-dev

2.从github将openni2源码clone下来

$git clone https://github.com/occipital/OpenNI2.git
$cd OpenNI2

3.修改两处配置Platform.Arm和CommonCppMakefile，适用于arm设备

$gedit ThirdParty/PSCommon/BuildSystem/Platform.Arm

Change:

CFLAGS+= -march=armv7-a -mtune=cortex-a9 -mfpu=neon -mfloat-abi=softfp#-mcpu=cortex-a8

to:

CFLAGS+= -march=armv7-a -mtune=cortex-a15 -mfpu=neon-vfpv4 -mfloat-abi=hard

$gedit ThirdParty/PSCommon/BuildSystem/CommonCppMakefile

---OpenNI2-2.2.0.30/ThirdParty/PSCommon/BuildSystem/CommonCppMakefile.old2014-03-28 19:09:11.572263107 -0700

+++OpenNI2-2.2.0.30/ThirdParty/PSCommon/BuildSystem/CommonCppMakefile 2014-03-2819:09:55.600261937 -0700

@@-95,6 +95,9 @@

OUTPUT_NAME= $(EXE_NAME)

# Wewant the executables to look for the .so‘s locally first:

LDFLAGS+= -Wl,-rpath ./

+ifneq ("$(OSTYPE)","Darwin")

+LDFLAGS += -lpthread

+endif

OUTPUT_COMMAND= $(CXX) -o $(OUTPUT_FILE) $(OBJ_FILES) $(LDFLAGS)

endif

ifneq "$(SLIB_NAME)" ""

4.修改makefile，增加sample，即在makefile文件末尾添加：

core_samples: $(CORE_SAMPLES)
tools: $(ALL_TOOLS)

5.编译

$make
$make core_samples # this probably isn‘t necessary, they should already be built
$GLUT_SUPPORTED=1 make tools#GLUT_SUPPORTED tells the make to compile NiViewer for OpenGL

6.安装libfreenect，否则无法驱动primesensor

安装依赖项

$sudo apt-get install cmake freeglut3-dev pkg-config build-essential libxmu-dev libxi-dev libusb-1.0-0-dev –y

下载源码并编译

$ git clone git://github.com/OpenKinect/libfreenect.git
$ cd libfreenect
$ mkdir build
$ cd build
$ cmake ..
$ make
$ sudo make install
# Build the OpenNI2 driver
$ cmake .. -DBUILD_OPENNI2_DRIVER=ON
$ make

将libfreenect的so拷贝到OpenNI的驱动文件夹下

$ Repository=../../Bin/Arm-Release/OpenNI2/Drivers
$ cp -L lib/OpenNI2-FreenectDriver/libFreenectDriver* ${Repository}

设置使用传感器的权限

$ sudo usermod -a -G video Ubuntu

7.回到openni2目录，将头文件和so文件拷贝到/usr目录下

$ sudo cp -r Include /usr/include/openni2
$ sudo cp -r Bin/Arm-Release/OpenNI2 /usr/lib/
$ sudo cp Bin/Arm-Release/libOpenNI2.* /usr/lib/

8.创建packageconfig文件

# this will enable ubuntu to find the location of the drivers, libraries and include files.
$ sudo gedit /usr/lib/pkgconfig/libopenni2.pc

and fill it with this:

prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include/openni2

Name: OpenNI2
Description: A general purpose driver for all OpenNI cameras.
Version: 2.2.0.0
Cflags: -I${includedir}
Libs: -L${libdir} -lOpenNI2 -L${libdir}/OpenNI2/Drivers -lDummyDevice -lOniFile -lPS1080.so

检验：

# To make sure it is correctly found, run
$ pkg-config --modversion libopenni2

# which should give the same version as defined in the file above (2.2.0.0)

最后一步：

# Linux has used the udev system to handle devices such as USB connected peripherals.

$ cd Packaging/Linux
$ sudo cp primesense-usb.rules /etc/udev/rules.d/557-primesense-usb.rules

三、PCL安装

参考：

http://larrylisky.com/2014/03/03/installing-pcl-on-ubuntu/

安装依赖环境

sudo apt-get install g++
sudo apt-get install cmake cmake-gui
sudo apt-get install doxygen  
sudo apt-get install mpi-default-dev openmpi-bin openmpi-common  
sudo apt-get install libflann1 libflann-dev
sudo apt-get install libeigen3-dev
sudo apt-get install libboost-all-dev
sudo apt-get install libvtk5.8-qt4 libvtk5.8 libvtk5-dev
sudo apt-get install libqhull*
sudo apt-get install libusb-dev
sudo apt-get install libgtest-dev
sudo apt-get install git-core freeglut3-dev pkg-config
sudo apt-get install build-essential libxmu-dev libxi-dev 
sudo apt-get install libusb-1.0-0-dev graphviz mono-complete
sudo apt-get install qt-sdk openjdk-7-jdk openjdk-7-jre
sudo apt-get install phonon-backend-gstreamer
sudo apt-get install phonon-backend-vlc

从github上下载pcl最新版本并编译

$git clone https://github.com/PointCloudLibrary/pcl.git pcl-trunk ln -s pcl-trunk pcl(我是直接下载了压缩包，解压的，不然太慢了)
$mkdir release
$cd release
$cmake -DCMAKE_BUILD_TYPE=None -DBUILD_GPU=ON -DBUILD_apps=ON -DBUILD_examples=ON ..
$make
$sudo make install

至此完成安装，但是是VTK有问题的，留着下次解决

四、最后再给出三个库同时使用的情形：

CMakeLists.txt

cmake_minimum_required(VERSION 2.8)

   ENDIF (OpenNI2_FIND_REQUIRED)
