Estimating 3D Polyhedral Building Models by Registering Aerial Images - Advanced Concepts for Intelligent Vision Systems - page 246

Fig. 6. Estimated 3D polyhedral models from aerial images. Despite the presence of
significant shadows the approach has provided the correct models.

Table 1. Method comparison associated with one facet having three vertices. The first
column depicts the estimated height of the model vertices obtained with a DEM. The
second (third) column displays the estimated heights using our approach with SSD
function (SAD function).

DEM SSD SAD

Vertex1 height 41.96m 42.75m 42.22m

Vertex2 height 41.36m 40.87m 40.98m

Vertex3 height 39.78m 40.10m 40.22m

Average deviation 0.0m 0.53m 0.36m
