In 2004, wang binyong et al. designed a small multi-spectral imager suitable for uav SE21, which is mainly based on the imaging method of multi-array CCD sensor, and has built-in aerial photography control software, which is equipped with flight control system communication, flight parameter collection, real-time data storage and other functions. According to the characteristics of remote sensing payload of uav, the flight test is carried out by using the remote sensing system of uav with large area array CCD camera, and the obtained images meet the requirements of accuracy. With the continuous development of uav technology, uav mapping plays a very important role in remote sensing mapping. The uav can carry a variety of remote sensing equipment, such as high-resolution CCD digital camera, laser scanner, optical camera, and so on, and process the collected image information through corresponding software to make it meet certain accuracy requirements. Image. In practical application, in order to adapt to the development of surveying and mapping, the corresponding resource information is provided to obtain accurate and complete remote sensing image data. Uav mapping technology can directly obtain the corresponding remote sensing information and can be applied in various fields.
