How to build COLMAP using Docker

Requirements

Host machine with at least one NVIDIA GPU/CUDA support and installed drivers (to support dense reconstruction).
Docker (for CUDA support 19.03+).

Quick Start

Check that Docker >=19.03 installed on your host machine:
bash
```
docker --version
```
Setup the NVIDIA driver and nvidia-toolkit on your host machine:

For Ubuntu host machines: ./setup-ubuntu.sh For CentOS host machines: ./setup-centos.sh
Run the run script, using the full local path to your preferred local working directory (a folder with your input files/images, etc.):
bash
```
./run.sh /path/where/your/working/folder/is
```
This will put you in a directory (inside the Docker container) mounted to the local path you specified. Now you can run COLMAP binaries on your own inputs like this:
bash
```
colmap automatic_reconstructor --image_path ./images --workspace_path .
```
Alternatively, you can run the run-gui script, which will start the graphical user interface of COLMAP:
bash
```
./run-gui.sh /path/where/your/working/folder/is
```

Build from Scratch

After completing steps 1-2, you can build the Docker image from scratch using the Dockerfile. First, update the CUDA and Ubuntu versions in Dockerfile lines 1-2 to match your system, then:

bash

./build.sh
./run.sh /path/where/your/working/folder/is
