Image data processing followed the standard photogrammetric pipeline.
All image datasets has been aligned in order to calculate internal and external orientation of the camera.
Ground control points has been marked a priori in the images in order to refine the alignment and to maximize the accuracy and precision of the datasets.
For every dataset has been chosen a appropriate amount of control point extracted from laser point cloud. Using a matching algorithm has been generated a point cloud of the measured surfaces that was oriented in the same coordinate system defined during the topographic campaign.
The resulting point cloud has been cleaned and merged with the laser dataset.
The data processing is focused to produce a 3D textured model of the Temenos.
Furthermore, the 3D point cloud is used to draw a 2D map and sections of the monument, to highlight the actual state and the degradation/structural problems.
