Hydrology and Water Resources
Using aerial vehicles without pilot (UAV-unmanned aerial vehicle) or Drone has seen a rapid development, over the last decade, in order to obtain spatial information of the Earth's surface. This scientific paper was realized for the Hydrotechnical Node of Costei, from Timis County and has as purpose the processing of aerial images, obtained from a Phantom4 Pro device, which is capable to capture video at 4K resolution at 30 frames per second and Full HD 1080p at 120 frames per second for a slow motion with a Sony EXMOR camera that can take photos at 12 megapixels, with a maximum flight speed of 20m/s. The device is equipped with positioning equipment, which connects to both GPS and GLONASS, allowing it to connect faster to satellites and position itself with high accuracy in the air. Phantom 4 automatically records the details of each flight made, so you can check your previous flights. In order to achieve the 3D model, were used oblique and vertical images with the highest accuracy. Nadir imaging was performed at an average height above ground (AGL–Above Ground Level) of approx. 140m. The imaging data was processed with the AgiSoft PhotoScan program using a number of 112 aerial images. For image processing, the software proposes for each processing stage, different parameters that determine the precision and time of the final processing of the Costei Hydrotechnical Node.
