Photogrammetry Case Study - Sun Ribbon.pdf

pdf

Abstract: The initial photogrammetry of this object was very noisy as photo alignment was not perfect. The main culprit was non-ideal visual features due to high reflectivity and the harsh sunlight combined with a generally flat and featureless surface of the object.

The initial pathing for this object could not capture all the necessary aspects to form a complete model.

Key Problems:

Benchmark Category	General Aspect	Subject-Specific Problem
Geometry	Detail	Very thin
Visual Features	Lack of features	Smooth, shiny, dark object
Environment	Ease of Photography	Limited space
	Lighting	Harsh lighting - bad contrast

Additional Techniques Used:

• Different Time of Day

• Adjusted Pathing

• Markers on Subject

Abstract: Nature is notorious in 3D scanning as its features are not easily distinguishable, making scan alignment a hurdle in this project.
