18.18.2. Photogrammetry and 3D Reconstruction

Try these first

1. 1.

   What is photogrammetry?

   Hint

   Think of how images are used to understand objects.

2. 2.

   Name a software tool used for photogrammetry.

   Hint

   These tools are related to UAVs and image processing.

3. 3.

   What technique is used to create 3D models from 2D images?

   • Lidar
   • Photogrammetry
   • Thermal Imaging

   Hint

   Think of how images can show depth.

4. 4.

   True or False: Structure from Motion (SfM) is a term for creating elevation models.

   • True
   • False

   Hint

   Consider the primary functions of SfM.

5. 5.

   Imagine you have been tasked with mapping a complex terrain using UAV images. Describe the steps you would take to ensure accurate photogrammetric modeling, including software considerations.

   Hint

   Think about the entire workflow from planning to processing.

6. 6.

   Discuss how varying weather conditions can affect photogrammetry results. What strategies might you implement to mitigate these challenges?

   Hint

   Reflect on the challenges each weather condition presents.
