Is photogrammetry hard?

The difficulty of photogrammetry can vary based on several factors, including the complexity of the project, the software used, the quality of input data, and the user's level of experience. Here are some considerations regarding the perceived difficulty of photogrammetry:

1. Basic Photogrammetry:

   • For simple projects, such as creating 3D models of small objects or basic terrain, some photogrammetry software is designed to be user-friendly and may have automated processes.
   • Entry-level photogrammetry software may not require advanced technical skills.

2. Complex Projects:

   • As the complexity of the project increases, such as mapping large areas, capturing intricate details, or dealing with challenging lighting conditions, the difficulty may rise.
   • High-end photogrammetry applications may have more features and require a deeper understanding of the underlying principles.

3. Photography Skills:

   • The quality of the input images is crucial. Knowing how to take well-exposed and well-composed photographs, understanding camera settings, and ensuring proper overlap between images contribute to successful photogrammetric outcomes.

4. Software Learning Curve:

   • The difficulty also depends on the photogrammetry software chosen. Some programs have user-friendly interfaces and are designed for beginners, while others may have steeper learning curves, especially for more advanced features.

5. Hardware Requirements:

   • Processing large datasets or working with high-resolution images may require a computer with sufficient processing power and memory. Understanding hardware requirements and ensuring access to suitable equipment can affect the ease of the photogrammetry process.

6. Experience and Training:

   • Like any skill, becoming proficient in photogrammetry takes practice and experience. Training resources, tutorials, and communities can be valuable for learning and troubleshooting.

In summary, basic photogrammetry for straightforward projects can be accessible to beginners, especially with user-friendly software. However, as projects become more complex or require advanced features, the learning curve may steepen. Patience, practice, and a willingness to learn are key to successfully mastering photogrammetry. Additionally, staying informed about best practices, attending training programs, and seeking help from experienced practitioners can contribute to overcoming challenges and improving skills in photogrammetry.
