COLMAP serves as a versatile pipeline for Structure-from-Motion (SfM) and Multi-View Stereo (MVS), featuring both graphical and command-line interfaces. This software provides an extensive array of functionalities for the reconstruction of both ordered and unordered collections of images. It operates under the new BSD license, with the most recent source code accessible on GitHub. Building upon previous research, users must also credit the original authors of specific algorithms utilized within COLMAP, as outlined in the source code documentation. For user convenience, the pre-compiled binaries for Windows include executables for both the graphical and command-line interfaces. To launch the COLMAP GUI, you can simply double-click the COLMAP.bat batch script or execute it from either the Windows command shell or Powershell. The command-line interface can be accessed in the same manner, as the batch script automatically configures the required library paths. Additionally, to view the list of available commands within COLMAP, you can execute COLMAP.bat -h in the cmd.exe command shell or Powershell. This flexibility in accessing the software makes it a powerful tool for image reconstruction tasks.
