Our research and development of "sky-air-ground" integrated intelligent agricultural monitoring system came into being. The system integrates technologies such as hyperspectral imaging, UAV group collaboration, ground intelligent equipment and AI decision-making platform to build a comprehensive monitoring system. With hyperspectral imaging technology, it accurately captures crop physiological and biochemical information and efficiently identifies pests and diseases and nutrient deficiencies. Through the cooperative operation of unmanned aerial vehicles and land vehicles, the three-dimensional cruise of farmland and intelligent obstacle avoidance are realized, the monitoring efficiency and coverage are greatly improved, and the agricultural monitoring is transformed from traditional manual inspection to intelligent and accurate monitoring. This project is committed to solving the core problems of inefficient traditional agricultural supervision, serious waste of resources, scattered data and slow disaster response, helping agricultural production to transform and upgrade towards digitalization, precision and sustainability, and providing strong support for the implementation of the rural revitalization strategy.
