Strengths & Limitations
Strengths
- +Provides a non-intrusive and efficient method for large-area data capture.
- +Generates detailed 3D data that can be used for multiple analytical purposes.
Limitations
The quality of the 3D model depends heavily on the drone's flight path, camera settings, and the processing software used. It may not capture fine details or very smooth surfaces accurately without proper calibration.
