• 网站: https://colmap.github.io/
• GitHub: https://github.com/colmap/colmap

安装

Windows

从 GitHub发布页 GitHub Releases 下载预编译的二进制, 区分带CUDA和不带CUDA的版本.

Ubuntu

在 Ubuntu 22.04 下可以通过apt install colmap安装, 但是这样安装的是不带CUDA支持的版本

支持CUDA的版本需要通过编译安装, 可以参考的安装说明

• https://github.com/colmap/colmap/issues/2366
• https://github.com/dberga/nerfstudio/blob/main/INSTALL.md

注意不要被 Conda 的环境影响

Make sure you configure and compile from a consistent dev environment. It seems you are using anaconda. You probably want to start from a clean build folder and make sure you are not in a virtual anaconda environment.

编译步骤 (参考 https://github.com/dberga/nerfstudio/blob/main/INSTALL.md )

1. 安装依赖

sudo apt-get install \git \cmake \ninja-build \build-essential \libboost-program-options-dev \libboost-filesystem-dev \libboost-graph-dev \libboost-system-dev \libeigen3-dev \libflann-dev \libfreeimage-dev \libmetis-dev \libgoogle-glog-dev \libgtest-dev \libsqlite3-dev \libglew-dev \qtbase5-dev \libqt5opengl5-dev \libcgal-dev \libceres-dev

导出仓库

git clone https://github.com/colmap/colmap.git

编译, 注意CMAKE_CUDA_ARCHITECTURES代表的是显卡硬件架构编号, rtx2080ti 对应75, rtx4060ti 对应89

cd colmap
mkdir build
cd build
cmake .. -GNinja -DCMAKE_CUDA_ARCHITECTURES=75
sudo chown -R $(whoami) .
ninja -j1 
sudo ninja install
