Unmanned Aerial Vehicle（UAV） remote sensing technology can obtain high-quality data in a low-cost and high-throughput way, and has become an important part of modern agriculture. In recent years, with the application of UAV remote sensing technology in agriculture. This paper aims to summarize the development status and problems of UAV remote sensing technology in agriculture, focusing on the specific application direction, existing problems and solving countermeasures. This paper introduces detailed examples of the application of UAV remote sensing technology in agriculture, including four aspects of crop growth monitoring, yield estimation, pest disaster monitoring and irrigation management. In addition, this article also discusses the challenges and existing problems faced by the application of drone remote sensing technology in the agricultural field, such as data processing and analysis, data integration and fusion, data accuracy and reliability, and drone operation supervision issues. Corresponding solutions are proposed to promote the development and promotion of drone technology on the basis of effective management of drones, and contribute to the sustainable development of agriculture.
