Ubuntu18.04下安装COLMAP
Ubuntu18.04下安装COLMAP
背景
最近在做NeRF⽅⾯的研究，看到了DS-NeRF，感觉挺适合作为baseline进⾏改进，所以跑了⼀下源码。试了⼀下官⽅的数据，没有问题。接着就想试⼀试⾃⼰的数据集。根据官⽅⽂档，要⽤⾃⼰的数据集的话需要⽤到COLMAP⽣成相机数据。所以开始了我的安（cai）装（keng）之路
附上DS-NeRF的GitHub：
Centos安装踩的坑
gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/usr/local/libexec/gcc/x86_64-unknown-linux-gnu/5.4.0/lto-wrapper
Target: x86_64-unknown-linux-gnu
Configured with: ../configure -enable-checking=release -enable-languages=c,c++ -disable-multilib
Thread model: posix
gcc version 5.4.0 (GCC)
gcc版本是5.4.0，⽀持c++11，满⾜要求
然后检查cmake版本运⾏cmake -version
cmake -version
cmake version 3.17.0-rc3
CMake suite maintained and supported by Kitware (kitware/cmake).
博客中推荐boost版本为1.58/1.66
本机器原版本为1.53，稳妥起见，更新到1.58
参考：
其他依赖也都装上：
sudo yum install
gflags-devel
glog-devel
ubuntu安装教程glew-devel
atlas
atlas-devel
lapack-devel
blas-devel
qt5-qtbase-devel
gflags和glog安装

分析依赖
⾸先要弄清楚包之间的依赖关系，⽅便检查有⽆缺失。
通过对于colmap进⾏cmake的结果来看

可见COLMAP的依赖为：CeresSolver、Boost、Eigen、FreeImage、Metis、Glog、OpenGL、Glew、CGAL、CUDA 这⼏个缺⼀不可

安装metis
安装OPENGL、CUDA、FreeImage
没什么好说的
安装Qt5
qmake -v
QMake version 3.1
Using Qt version 5.15.2 in /usr/local/Qt-5.15.2/lib
测试COLMAP是否成功
由于没有图像化界⾯，咱们采⽤命令⾏测试
附上教程：
先scp传点图⽚然后运⾏命令：
colmap feature_extractor --database_path ./database.db --image_path ../images
