• Scalability
  openMVG can handle large datasets effectively, making it suitable for complex and large-scale projects.

Possible disadvantages of openMVG

• Steep Learning Curve
  Despite its documentation, openMVG can be challenging for beginners to master due to its complexity and the depth of knowledge required in multiple-view geometry.
• Performance
  Being an open-source project, it might not be as optimized for performance as some commercial software, potentially leading to longer processing times.
• Sparse Support for Non-Standard Workflows
  The library is designed with standard multiple-view geometry workflows in mind, which might limit flexibility for custom or non-standard applications.
• Reliance on Additional Libraries
  openMVG often requires integration with other libraries (e.g., OpenCV, Eigen) for full functionality, which can complicate setup and dependency management.
• Limited User Interface
  The library does not offer a robust graphical user interface, necessitating more command-line proficiency and manual coding.
