本文环境

my@test:~$ hostnamectl
Icon name: computer-desktop
Chassis: desktop
Operating System: Ubuntu 20.04.6 LTS
Kernel: Linux 5.15.0-117-generic
Architecture: x86-64

退出conda环境

建议退出conda环境，conda环境的libtiff.so等动态链接库可能会影响到opencv的安装

conda deactivate

openssl的安装

cmake的安装需要OpenSSL 的头文件和库文件，Ubuntu 20.04LTS 系统自带 OpenSSL ，但是这个OpenSSL 是没有<头文件.h>和<动态库文件.so及静态库文件.a>的，所以需要手动下载。

sudo apt-get install libssl-dev

my@test:~/下载$ sudo apt-get install libssl-dev

正在读取软件包列表... 完成
正在分析软件包的依赖关系树       
正在读取状态信息... 完成

...

此方法会把OpenSSL的头文件放在 “/usr/include/openssl” ，动态库文件（libssl.so、libcrypto.so）、静态库文件（libssl.a、libcrypto.a）均放在 “/lib/x86_64-linux-gnu”

未下载OpenSSL头文件、库文件，cmake安装会报以下错误：Could not find OpenSSL

cmake的安装

1. cmake下载

Download CMake cmake网址

点击上述链接进入gitlab页面可下载cmake指定版本，以及可查看安装过程的指令CMake / CMake · GitLabCMake, the cross-platform, open-source build system.https://gitlab.kitware.com/cmake/cmake

本文使用cmake3.30.4 source源码版本

2. 解压

tar -xvzf cmake-3.30.4.tar.gz

my@test:~/下载$ tar -xvzf cmake-3.30.4.tar.gz
cmake-3.30.4/
cmake-3.30.4/.clang-format
cmake-3.30.4/.clang-tidy
cmake-3.30.4/Auxiliary/
cmake-3.30.4/Auxiliary/CMakeLists.txt
cmake-3.30.4/Auxiliary/bash-completion/

...

当然，如果是ubuntu桌面版，可以直接右击“提取到...”

3. 执行“文件检查&编译&安装”

cd cmake-3.30.4/./bootstrap && make -j8 && sudo make install

my@test:~/下载$ cd cmake-3.30.4/

my@test:~/下载/cmake-3.30.4$ ./bootstrap && make -j8 && sudo make install

cmake安装到了/usr/local/share/cmake-3.30路径

报错

CMake Error at /home/my/anaconda3/lib/cmake/Qt5Gui/Qt5GuiConfigExtras.cmake:9 (message):
  Failed to find "GL/gl.h" in

  Tests/CMakeLists.txt:280 (find_package)

会看到链接动态库到anaconda了，是由于没退出anaconda base环境造成的，先conda deactivate，再删除CMakeCache.txt，重新./bootstrap && make -j8 && sudo make install

5. 软链接

sudo ln -sf /usr/local/bin/cmake /usr/bin/

6. 验证版本

my@test:~/下载/cmake-3.30.4$ cmake --version
cmake version 3.30.4

CMake suite maintained and supported by Kitware (kitware.com/cmake).

opencv的安装

1. 下载依赖

sudo apt-get install build-essential unzip pkg-configsudo apt-get install libjpeg-dev libpng-dev libtiff-devsudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-devsudo apt-get install libxvidcore-dev libx264-devsudo apt-get install libgtk-3-devsudo apt-get install libatlas-base-dev gfortransudo apt-get install python3-dev

2. opencv下载

https://opencv.org/releases/ opencv下载

https://github.com/opencv/opencv_contrib/releases/tag/4.10.0 opencv_contrib下载

3. 解压

unzip opencv-4.10.0.zipunzip opencv_contrib-4.10.0.zip

my@test:~/下载$ unzip opencv-4.10.0.zip 
Archive:  opencv-4.10.0.zip
71d3237a093b60a27601c20e9ee6c3e52154e8b1
  creating: opencv-4.10.0/
  inflating: opencv-4.10.0/.editorconfig

...

当然，如果是ubuntu桌面版，可以直接右击“提取到...”

4.移动opencv_contrib

将opencv_contrib-4.10.0移到opencv-4.10.0文件夹下

5. cmake链接

cmake opencv_contrib-4.10.0会下载外网额外的组件，注意网速慢

cd opencv-4.10.0/mkdir buildcd buildcmake -D CMAKE_BUILD_TYPE=Release -D OPENCV_EXTRA_MODULES_PATH=../opencv_contrib-4.10.0/modules ..

my@test:~/下载/opencv-4.10.0/build$ cmake -D CMAKE_BUILD_TYPE=Release -D OPENCV_EXTRA_MODULES_PATH=../opencv_contrib-4.10.0/modules ..
CMake Warning (dev) at CMakeLists.txt:127 (enable_language):
  project() should be called prior to this enable_language() call.
This warning is for project developers.  Use -Wno-dev to suppress it.

-- The C compiler identification is GNU 9.4.0
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Check for working CXX compiler: /bin/c++ - skipped

如果有报错信息如下：

CMake Error at CMakeLists.txt:10 (message):
  

  FATAL: In-source builds are not allowed.

         You should create a separate directory for build files.

-- Configuring incomplete, errors occurred!

则需要先删除cmake缓存

rm ../CMakeCache.txt

6. 编译

make -j8

my@test:~/下载/opencv-4.10.0/build$ make -j8
[  0%] Built target opencv_videoio_plugins
[  0%] Built target opencv_dnn_plugins
[  0%] Built target opencv_highgui_plugins

...

报错1

报错信息：

fatal error: openjpeg.h: No such file or directory

原因是找不到openjpeg文件，我的解决是修改报错信息中给的.hpp文件：

先locate openjpeg.h，输出/usr/include/openjpeg-2.3/openjpeg.h

修改.hpp文件的引入

//#include <openjpeg.h>
#include </usr/include/openjpeg-2.3/openjpeg.h>

报错2

/usr/lib/x86_64-linux-gnu/libopencv_imgcodecs.so.3.2.0: undefined reference to `TIFFReadDirectory@LIBTIFF_4.0'
//usr/lib/libgdal.so.20: undefined reference to `TIFFLastDirectory@LIBTIFF_4.0'

//usr/lib/libgdal.so.20: undefined reference to `TIFFSwabArrayOfShort@LIBTIFF_4.0'

在确保libtiff-dev已安装的情况下，sudo apt-get install libtiff4-dev

cmake指令增加 -D BUILD_TIFF=ON

7. 安装opencv

sudo make install

my@test:~/下载/opencv-4.10.0/build$ sudo make install 
[  0%] Built target opencv_dnn_plugins
[  0%] Built target opencv_highgui_plugins
[  2%] Built target libopenjp2

SIBR_viewers的安装

GitHub - graphdeco-inria/gaussian-splatting: Original reference implementation of "3D Gaussian Splatting for Real-Time Radiance Field Rendering"

gs谈到了SIBR的安装，但是我的安装过程有报错

1. 依赖安装

sudo apt install -y libglew-dev libassimp-dev libboost-all-dev libgtk-3-dev libopencv-dev libglfw3-dev libavdevice-dev libavcodec-dev libeigen3-dev libxxf86vm-dev libembree-dev

my@test:~/postg/thesis/gaussian-splatting/SIBR_viewers$ sudo apt install -y libglew-dev libassimp-dev libboost-all-dev libgtk-3-dev libopencv-dev libglfw3-dev libavdevice-dev libavcodec-dev libeigen3-dev libxxf86vm-dev libembree-dev
正在读取软件包列表... 完成
正在分析软件包的依赖关系树       
正在读取状态信息... 完成 

2. 切换SIBR的分支

如果是ubuntu20.04，还需要切换SIBR的分支，如果是ubuntu22.04则不需要

cd SIBR_viewersgit checkout fossa_compatibility

my@test:~/postg/thesis/gaussian-splatting/SIBR_viewers$ git checkout fossa_compatibility
M    CMakeLists.txt
M    src/projects/remote/CMakeLists.txt
已经位于 'fossa_compatibility'
您的分支与上游分支 'origin/fossa_compatibility' 一致。

3. cmake链接

cmake -Bbuild . -DCMAKE_BUILD_TYPE=Release

报错1

中途可能卡顿，是因为在下载其他依赖组件。我的解决方法是换一个cmake版本（比如使用sudo apt-get install cmake），就成功了

--Populating library imgui...

报错2

报错信息：

CMake Error in src/core/system/CMakeLists.txt:
  Imported target "Boost::system" includes non-existent path

    "/include"

  in its INTERFACE_INCLUDE_DIRECTORIES.  Possible reasons include:

  * The path was deleted, renamed, or moved to another location.

  * An install or uninstall procedure did not complete successfully.

  * The installation package was faulty and references files it does not
  provide.”

直接有效的解决方法是创建/include文件夹，并将boot文件夹复制到include文件夹下

locate boost/version.hpp  ##定位boost文件夹，我的boost文件是在 /usr/include/boost

sudo mkdir /include

sudo cp -r /usr/include/boost/ /include/ ##复制文件夹

4. 编译安装

cmake --build build -j24 --target install

报错

报错信息：

   29 | #  include <opencv2/opencv.hpp>
      |            ^~~~~~~~~~~~~~~~~~~~

解决方法：c++ 中——fatal error: opencv2/opencv.hpp: No such file or directory #include ＜opencv2/opencv.hpp＞_opencv2: no such file or directory #include <openc-CSDN博客

至此，SIBR安装完毕

SIBR运行

将3D gaussian-splatting代码在ubuntu20.04 & CUDA11.8下的配置_3d gaussian splatting 环境搭建 ubuntu-CSDN博客

中的训练结果运行，训练结果的目录结构如下：

my@test:~/postg/thesis/gaussian-splatting/data$ tree output

        └── iteration_7000
            └── point_cloud.ply

4 directories, 5 files

1. 运行SIBR

cd install/bin./SIBR_gaussianViewer_app -m /home/my/thesis/gaussian-splatting/data/output/

报错1

报错信息：

my@test:~/thesis/gaussian-splatting/SIBR_viewers/install/bin$ ./SIBR_gaussianViewer_app -m /home/my/thesis/gaussian-splatting/output/

./SIBR_gaussianViewer_app: error while loading shared libraries: libwebp.so.7: cannot open shared object file: No such file or directory

（1）查看依赖的动态链接库，发现部分没链接上

ldd ./SIBR_gaussianViewer_app

my@test:~/thesis/gaussian-splatting/SIBR_viewers/install/bin$ ldd ./SIBR_gaussianViewer_app

        libwebp.so.7 => not found
        libLerc.so => not found
        libjpeg.so.9 => not found
        libdeflate.so.0 => not found

（2）手动创建链接，先找到动态链接库，如果没有就sudo apt-get install ...

locate libwebp.so.7

my@test:~/thesis/gaussian-splatting/SIBR_viewers/install/bin$ locate libwebp.so.7

/home/my/anaconda3/lib/libwebp.so.7

（3）然后将.so复制到lib中

cp /home/my/anaconda3/lib/libwebp.so.7 /home/my/thesis/gaussian-splatting/SIBR_viewers/install/lib/

my@test:~/thesis/gaussian-splatting/SIBR_viewers/install/bin$ cp /home/my/anaconda3/lib/libwebp.so.7 /home/my/thesis/gaussian-splatting/SIBR_viewers/install/lib/

（4）再调用 ldd ./SIBR_gaussianViewer_app 查看动态库是否链接上

报错2

已放弃 (核心已转储)

（1）是因为OpenGL的版本问题，解决如下，查看OpenGL的版本：

sudo apt install mesa-utils -yglxinfo | grep OpenGL

my@test:~/thesis/gaussian-splatting/SIBR_viewers/install/bin$ glxinfo | grep OpenGL
OpenGL vendor string: Mesa/X.org
OpenGL renderer string: llvmpipe (LLVM 12.0.0, 256 bits)
OpenGL core profile version string: 4.5 (Core Profile) Mesa 21.2.6
OpenGL core profile shading language version string: 4.50
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 3.1 Mesa 21.2.6
OpenGL shading language version string: 1.40
OpenGL context flags: (none)
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.2 Mesa 21.2.6
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20
OpenGL ES profile extensions:

其中OpenGL core profile version string: 4.5，则直接指令带上MESA_GL_VERSION_OVERRIDE=4.5即可

MESA_GL_VERSION_OVERRIDE=4.5 ./SIBR_gaussianViewer_app -m /home/my/thesis/gaussian-splatting/output/

可视化结果

键位：qweasd控制平移，uiojkl控制旋转

q下，e上，w前进，s后退

选择trackball，可以用鼠标进行旋转

这个ubuntu环境下的可视化配置耗费我很多时间，直接在windows上可视化更方便，也早已实现。我也深刻理解了奥卡姆剃刀原则--“如无必要，勿增实体”，谨记。
