Ubuntu 環境 openMVG+openMVS 配置

1. openMVG

比較簡單，直接按照 build wiki 的步驟一步一步來就沒問題。

Instruction: Build on Linux

# Install the required external libraries.
sudo apt-get install libpng-dev libjpeg-dev libtiff-dev libxxf86vm1 libxxf86vm-dev libxi-dev libxrandr-dev

# If you want see the view graph svg logs, install Graphviz.
$ sudo apt-get install graphviz

# Checkout OpenMVG.
$ git clone --recursive https://github.com/openMVG/openMVG.git

# 設置編譯和安裝路徑
$ cd openMVG
$ mkdir openmvg-build
$ mkdir openmvg-bin
$ cd openmvg-build

# Configure and build
$ cmake -DCMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=/path/to/openMVG/openmvg-bin ../src/
$ cmake --build . --target install

2. openMVS

2.1 這一步就比較麻煩了，因為wiki里面的指導不一定能安裝成功。

# Prepare and empty machine for building
apt-get update && apt-get install -qq
apt-get -y install build-essential git mercurial cmake libpng-dev libjpeg-dev libtiff-dev libglu1-mesa-dev libxmu-dev libxi-dev

#Boost (Required)
apt-get -y install libboost-iostreams-dev libboost-program-options-dev libboost-system-dev libboost-serialization-dev

#Eigen (Required)
git clone https://gitlab.com/libeigen/eigen.git --branch 3.3
cd eigen
mkdir eigen-build && cd eigen-build
cmake . .. -CMAKE_INSTALL_PREFIX=/path/to/eigen/eigen-bin
make && make install
cd ../..

2.2 下面這一步可能會出現問題，最好自己下載源碼編譯

#OpenCV (Required)
apt-get -y install libopencv-dev

# Build opencv from source
git clone https://github.com/opencv/opencv.git
cd opencv
git reset --hard 3.4.1
mkdir opencv-bin
mkdir opencv-build && cd opencv-build
cmake -DCMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=/path/to/opencv/opencv-bin ..
make -j8
make install

2.3 接下來的兩個庫直接按步驟就可以

#CGAL (Required)
apt-get -y install libcgal-dev libcgal-qt5-dev

#VCGLib (Required)
git clone https://github.com/cdcseacave/VCG.git vcglib

#Ceres (Required)
apt-get -y install libatlas-base-dev libsuitesparse-dev

# If google source encounter connection time out, try github
# git clone https://ceres-solver.googlesource.com/ceres-solver ceres-solver
git clone https://github.com/ceres-solver/ceres-solver.git

cd ceres-solver
git reset --hard 1.14.0
mkdir ceres-bin
mkdir ceres-build && cd ceres-build
cmake . ../ -DMINIGLOG=ON -DBUILD_TESTING=OFF -DBUILD_EXAMPLES=OFF
make -j2 && sudo make install
cd ../..

#GLFW3 (Optional)
apt-get -y install freeglut3-dev libglew-dev libglfw3-dev

2.4 進入主要步驟

#OpenMVS
git clone https://github.com/cdcseacave/openMVS.git openMVS
cd openMVS
mkdir openmvs-bin
mkdir openmvs-build && cd openmvs-build

cmake . ../ -DCMAKE_BUILD_TYPE=Release -DVCG_ROOT="/path/to/vcglib" -DBUILD_SHARED_LIBS=ON

#If something goes wrong, try to set shared libs OFF

#Install OpenMVS library (optional):
make -j8 && make install

2.5 make的過程中出現undefined reference錯誤記錄如下

make[1]: *** [apps/Viewer/CMakeFiles/Viewer.dir/all] Error 2

make: *** [all] Error 2

openMVS的git issue里面提到的思路或許能解決問題

in CMakeList.txt, add lines like below (replace {{target_name}} to your own):

find_package(Boost COMPONENTS system filesystem REQUIRED)
target_link_libraries({{target_name}} ${Boost_FILESYSTEM_LIBRARY})
target_link_libraries({{target_name}} ${Boost_SYSTEM_LIBRARY})

實際解決時，在每一個模塊下面的CMakeLists.txt中添加動態鏈接庫

# openMVS/apps/InterfaceCOLMAP/CMakeLists.txt
cxx_executable_with_flags_no_pch(InterfaceCOLMAP "Apps" "${cxx_default}" "MVS;${OpenMVS_EXTRA_LIBS}" ${LIBRARY_FILES_C} ${LIBRARY_FILES_H})

target_link_libraries(InterfaceCOLMAP
        ${OpenCV_LIBRARIES}
        ${Boost_LIBRARIES}
        )

2.6 運行過程中遇到以下的問題

error: "There is no defined intrinsic data in order to compute an essential matrix for the initial pair."

解決方案

參考 openMVS git issue

 

至此配置完成，找一些數據如Middlebury dino/temple、DTU scan9、ETHD Pipes、Strecha fountain-P11等就可以運行測試了。
