Computation System OS : windows 7 professional Processor : Intel core I7-4930k CPU @ 3.40 GHz (8 processors / 16 threads) RAM : 64 Go GPU : Nvidia GeForce GTX 980 1.2. Dataset The dataset is composed of 203 pictures over the city of Graz (Austria). The dataset was acquired from a Microsoft UltraCam Osprey mounted on an airplane and is composed of 39 nadir and 164 oblique photos. Position and orientation information are available for each photo of the dataset. The multi-cameras system is composed of: 1 Nadir camera o Sensor size : 70.044*45.084 mm o focal length : 80 mm o Photo dimensions : 11674*7514 Pix o boresight angle : vertical o orientation : landscape (according to flight direction). 2 oblique cameras oriented forward and backward o Sensor size : 53.4*39.9 mm o focal length : 120 mm o Photo dimensions : 8900*6650 Pix o boresight angle : 45° from vertical o orientation : landscape 2 oblique cameras oriented left and right o Sensor size : 53.4*39.9 mm o focal length
