UAV remote sensing sensor is based on remote sensing tasks of different types, the use of airborne equipment remote sensing corresponding, such as high resolution CCD camera, digital camera, light optical multispectral imaging instrument, infrared scanner, laser scanner, magnetometer, synthetic aperture radar etc.. The use of remote sensing sensor should be digital, small size, light weight, high precision, large storage capacity, excellent performance and so on. UAV remote sensing technology can quickly update, modify and upgrade the geological environment information and outdated GIS database. Provide timely technical guarantee for administration, land and geological environment management of government and related departments.
The sensor image automatic identification and rapid stitching software in the data processing, fast processing and quick check data can quickly realize the image quality, the flight quality, to meet the real-time technical requirements of the whole system. Further modeling, analysis of the use of the remote sensing image processing software. Many small digital cameras use the UAV remote sensing system (or scanner) as the airborne remote sensing equipment, compared with the traditional aerial, existing problems like the smaller, more than the number of images, according to the characteristics of the remote sensing images and camera calibration parameters, shooting (or scanned) when the attitude data and related geometric models the geometric and radiometric correction of the image, the development of the corresponding software of interactive processing.
Remote sensing UAV can be divided into fixed wing UAV, unmanned remote sensing machine two kinds of types, no fixed airfoil and wing gliding through the power system to realize man-machine landing and flight, flight and flight control remote control are easy to realize, the wind resistant capacity is relatively strong, there are many types, can be equipped with a variety of sensors at the same time. Take off way taxiing, ejection, vehicle, rocket and aircraft on the way; landing taxiing, parachute and net etc.. Fixed wing UAV landing needs more empty space, more suitable for mine resources, forestry and pasture monitoring aerial aerial monitoring, aerial monitoring, marine environmental pollution source and diffusion monitoring, land use monitoring, water conservancy and electric power aerial photography.
The advantage of unmanned aerial vehicle is that it can take off and land at a certain point, and the requirement for the landing site is not high. However, the structure of unmanned remote sensing is relatively complex, the difficulty of control is also large, so the species is limited, mainly used in the investigation of emergencies, such as single landslide exploration, volcanic environment monitoring and other fields.
The existing aerial remote sensing technology can not meet the needs of economic development. New remote sensing technology for the development of economic construction and cultural services. Aerial platform technology based on remote sensing UAV, it is a new technology developed to meet these needs, can better satisfy the present demand of aerial remote sensing business in our country, the old geographic data update.
