   Hint

   Think about how colors help identify issues.

2. 2.

   Name one advantage of infrared cameras.

   Hint

   Consider what happens when water is present in structures.

3. 3.

   What is the primary function of an RGB camera in structural inspection?

   • Detect thermal anomalies
   • Capture color images
   • Create 3D models

   Hint

   Consider what colors reveal about a structure’s condition.

4. 4.

   True or False: Infrared cameras can only detect surface-level damage.

   • True
   • False

   Hint

   Think about where problems might be hidden.

5. 5.

   Propose a scenario where visual sensors could misidentify a problem in structural inspections. Discuss how to mitigate such risks.

   Hint

   Consider environmental factors that impede visibility.

6. 6.

   Design a comprehensive inspection plan using both RGB and infrared cameras for a large bridge. Discuss key factors to ensure successful application.

   Hint

   Think about how often and when inspections should take place for accuracy.
