Aerial photography:

UAV aerial photography takes UAV as the aerial platform and obtains information from airborne remote sensing equipment, such as high-resolution CCD digital camera, optical light camera, infrared scanner, laser scanner, magnetic detector and so on. The image information is processed by computer and made into images according to certain accuracy requirements.

The whole system has outstanding characteristics in design and optimization combination, and it is a new application technology integrating high-altitude shooting, remote control, telemetry technology, video image microwave transmission and computer image information processing.
