1.CUDA和CUDNN安装

  • [1] WSL版本cuda安装： 
    >> wget https://developer.download.nvidia.com/compute/cuda/repos/wsl-ubuntu/x86_64/cuda-wsl-ubuntu.pin
>> sudo mv cuda-wsl-ubuntu.pin /etc/apt/preferences.d/cuda-repository-pin-600
>> wget https://developer.download.nvidia.com/compute/cuda/11.7.1/local_installers/cuda-repo-wsl-ubuntu-11-7-local_11.7.1-1_amd64.deb
>> sudo dpkg -i cuda-repo-wsl-ubuntu-11-7-local_11.7.1-1_amd64.deb
>> sudo cp /var/cuda-repo-wsl-ubuntu-11-7-local/cuda-*-keyring.gpg /usr/share/keyrings/
>> sudo apt-get update
>> sudo apt-get -y install cuda
    • [2] cudnn安装： 
      # 1.下载cudnn-linux-x86_64-8.9.2.26_cuda11-archive.tar.xz文件
# 2.解压cudnn压缩包
>> tar -xf cudnn-linux-x86_64-8.9.2.26_cuda11-archive.tar.xz
# 3.将include和lib文件夹下文件拷贝到cuda安装目录下
>> sudo cp cudnn-linux-x86_64-8.9.2.26_cuda11-archive/include/*cudnn.h /usr/local/cuda/include/
>> sudo cp  cudnn-linux-x86_64-8.9.2.26_cuda11-archive/lib/libcudnn* /usr/local/cuda/lib64
# 4.修改库的权限
>> sudo chmod a+r /usr/local/lib64/libcudnn*
      • [3] 添加系统环境变量(.zshrc或.bashrc) 
        export CUDA_PATH=/usr/local/cuda
export CUDA_BIN=/usr/local/cuda/bin
export PATH=$PATH::$CUDA_PATH:$CUDA_BIN
        • [4] 刷新一下系统环境变量 
          # 1.zsh
>> source ~/.zshrc
# 2.bash
>> source ~/.bashrc
          • [5] 查询cuda版本 
            >> nvcc --version
nvcc: NVIDIA (R) Cuda compiler driver

            2.安装依赖库

            2.1 apt安装依赖库

            sudo apt-get -y install git cmake libpng-dev libjpeg-dev libtiff-dev libglu1-mesa-dev
sudo apt-get -y install libboost-iostreams-dev libboost-program-options-dev libboost-system-dev libboost-serialization-dev
sudo apt-get -y install libcgal-dev libcgal-qt5-dev
sudo apt-get install libglfw3-dev

            2.2 OpenCV安装

            • 网上一大堆，懒得写了

              3.OpenMVS编译

              # 1.下载VCG源码
>> git clone https://github.com/cdcseacave/VCG.git vcglib
# 2.下载OpenMVS源码
>> cmake .. -DVCG_ROOT=[VCG源码路径]/vcglib -DCMAKE_BUILD_TYPE=Release

                4.效果测试

                4.0 测试数据

                • openMVS_sample

                  4.1 稠密点云重建(可选项)

                  • 当场景部分缺失时，稠密点云重建模块可以估算一个稠密点云来恢复它们，默认采用patch匹配方法： 
                    >> ./bin/DensifyPointCloud -w [openMVS_sample路径]/mvs-data scene.mvs
                    • 使用meshlab打开点云结果scene_dense.ply

                      4.2 粗略网格重建

                      • 先前获取得到的稀疏或稠密点云被用于网格重建模块： 
                        >> ./bin/ReconstructMesh -w [openMVS_sample]/mvs-data scene_dense.mvs -p scene_dense.ply
                        • 使用meshlab打开网格生成结果scene_dense_mesh.ply：

                          4.3 网格细化(可选项)

                          • 从点云获取到的网格可以进一步细化，进而恢复所有好的细节，更有甚者，恢复更大缺失的部分：
                          • (a) 细化由稀疏点云获取到的网格： 
                            >> ./bin/RefineMesh -w [openMVS_sample]/mvs-data scene.mvs -m scene_dense_mesh.ply -o scene_sparse_mesh_refine.mvs
                            • 看一下结果：

                            • (b) 细化由稠密点云获取到的网格： 
                              >> ./bin/RefineMesh -w [openMVS_sample]/mvs-data scene_dense.mvs -m scene_dense_mesh.ply -o scene_dense_mesh_refine.mvs
                              • 看一下效果：

                                4.4 网格纹理化

                                • 前面步骤获取到的网格被用于网格纹理化模块： 
                                  >> ./bin/TextureMesh -w [openMVS_sample]/mvs-data  scene_dense.mvs -m scene_dense_mesh_refine.ply -o scene_dense_mesh_refine_texture.mvs
                                  • 看一下结果：
