Case Studies

Photogrammetry

This article features case studies of the photogrammetry process. They will show how the Benchmark (linked below) has been applied, the challenges the subject presented and the additional techniques that were applied to successfully capture the subject.

Sun Ribbon

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.
