3D Modeling

   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 aquisition angle of aprox. 30 degrees, but multiple wieving can increase the reconstruction details and accuracy. This oblique aquisition can be done for aerial flights with special metric oblique cameras (   multi-sensors cameras with integrated nadir and obliques cones, like Vexcel Ultracam Osprey , Leica RCD30, IGI Penta DigiCAM ). For UAV, non-metric cameras can be used with an oblique viewing  from multiples angles and combined also with nadiral viewing and even with close range images from terrain,  close to 90 degree viewing, for very high details of some important element that requires a total reality reconstruction.
