Test F3F3: Clark and Tikir Photometric Function - Analysis
Since the Clark and Tikir photometric function behaved so differently to the Lommel-Seeliger photometric function during testing, the sub-test results are analyzed here in detail. The F3F3 sub-test digital terrain model (Clark and Tikir photometric function) suffered from pervasive degradation with every processing step performed, eventually failing to build topography for a subset of landmarks at the 5cm tiling step. This failure is illustrated by the 5cm Landmark Test, reported below.
5cm Landmark Test
Background: A subset of new landmarks (28 of 225) created during the 5cm tile failed to achieve minimum image correlations across the images. At 5cm each landmarks contains approximately 12 Detailed Survey PolyCam images. At this scale elimination of low correlating images is not allowed, instead low-correlating images must be aligned by hand. On investigation it was found that the lithos template degraded rapidly with iteration leading to rapid loss of image correlation scores. This behavior was found to be pervasive across landmarks of all latitudes within the TAG site region, all available viewing conditions and all ground sample distances (GSDs) including the start model landmarks at 35cm, 75cm, and 150cm GSD.
