Design and Principle Analysis of UAV Remote Sensing Sensor Circuit

inductance

Remote sensing UAV sensors are based on different types of remote sensing tasks, using corresponding on-board remote sensing devices, such as high-resolution CCD digital cameras, light optical cameras, multi-spectral imagers, infrared scanners, laser scanners, magnetic meters, Synthetic aperture radar, etc. The remote sensing sensor used should be digital, small in size, light in weight, high in precision, large in storage capacity, and excellent in performance. UAV remote sensing technology quickly updates, modifies, and upgrades geological environment information and outdated GIS databases. Provide timely technical guarantees for the administration, land and geological environment management of the government and relevant departments.

Analysis of Remote Sensing Sensor Data Processing Technology

The sensor has automatic image recognition and fast splicing software in data processing, which can quickly realize image quality, rapid inspection of flight quality and rapid processing of data to meet the real-time and fast technical requirements of the whole system. Further construction and analysis use the corresponding remote sensing image processing software. At present, the UAV remote sensing system uses a small digital camera (or scanner) as the on-board remote sensing device. Compared with the traditional aerial film, there are problems such as small image size and large number of images, and the characteristics of the remote sensing image and Camera calibration parameters, attitude data during shooting (or scanning), and geometry and radiation correction of the image with respect to the geometric model, and corresponding software developed for interactive processing.

Unused remote sensing technology

Remote sensing drones can be divided into two types: fixed-wing UAVs and unmanned remote sensors. Fixed-wing UAVs can take off and land and fly through the power system and wing taxiing. Both remote control and program-controlled flight are easy. Realized, the wind resistance is also strong, and there are many types, which can carry a variety of remote sensing sensors at the same time. The take-off modes include taxiing, ejection, on-board, rocket boosting, and aircraft launching; landing methods include taxiing, parachute, and collision. The take-off and landing of fixed-wing UAVs requires relatively empty space, which is more suitable for aerial resources aerial monitoring, forestry and grassland aerial photography, marine environmental aerial monitoring, pollution source and diffusion situation monitoring, land use monitoring, and water conservancy and electric power aerial photography. application.

Unmanned remote sensing aircraft technology advantage

The technical advantage of the unmanned remote sensing aircraft is that it can take off and land at a fixed point. The requirements for the landing and landing site are not high. The flight is also controlled by radio remote control or through an onboard computer. However, the structure of the unmanned remote sensing machine is relatively complicated and difficult to operate. Therefore, the type is limited, and it is mainly used in the investigation of emergencies, such as single landslide exploration and volcanic environment monitoring.

Unmanned remote sensing machine application field

A: UAVs are used to capture low-altitude large-scale images, and the FORMOSAT2 classification is used for anomaly extraction to intercept illegal dumpings (solid waste, etc.) in Taoyuan County for environmental pollution and law enforcement investigations.

B: Using remote sensing drones to conduct natural disaster investigations and accurately assess the loss of yards and villages through orthophoto processing and analysis. It shows the rapid reflection capability of UAV remote sensing technology and provides timely and accurate data for disaster management.

C: UAVs can quickly reach the scenes in areas that are difficult for people to access. On-board high-precision digital cameras and radar scanners can be used to investigate the erupting volcanoes and evaluate the disaster.

The existing methods of aerial remote sensing technology have been unable to meet the needs of economic development. The new remote sensing technology serves the growing economic construction and cultural undertakings. The technology of using remote sensing drone as aerial photography platform is a new applied technology developed to meet this need. It can better meet the needs of China's aviation remote sensing business at present, and update old geographic data. .
