3D modeling or 3D reconstruction it’s a special approach of data processing, based on special algorithms, that can be accomplish for images with an acquisition angle of aprox. 30 degrees. Multiples viewing angles it’s a plus and this aspect can increase the final reconstruction details and accuracy. This oblique acquisition can be done, for aerial flights, with special metric oblique cameras (multi-sensors cameras with integrated nadir and obliques cone, like Vexcel Ultracam Osprey, Leica RCD30, IGI Penta DigiCAM). For UAV, non-metric cameras can be used, with an oblique viewing from multiple angles. Combined with nadiral view and even with close ranged images from terrain (close to 90 degree viewing) the total reconstruction, for some important elements of interest, can be reproduced with high fidelity (reality reconstruction).
