In modern agricultural engineering, plant protection UAV has been widely recognized and used, it use the advanced flight control, intelligent flow control and large data platform to ensure the precise farming. But another application of agricultural unmanned aerial vehicles cannot be ignored - agricultural remote sensing. Remote sensing is considered another potential market for agricultural unmanned aerial vehicles. With the accelerated pace of precision agriculture, remote sensing represents another broad future for agricultural unmanned aerial vehicles.
Nowadays agricultural drone remote sensing mainly have following functions:
1. Monitoring pests and diseases and aerial pesticide spraying
Pests and diseases are a direct factor affecting crop yields and are one of the major agricultural disasters in the world. Large-scale pests and diseases will cause huge losses to agricultural production and the national economy. According to the United Nations Food and Agriculture Organization statistics, world food production losses due to pests and diseases accounted for more than 20% of total grain output.
The use of remote sensing monitoring technology to follow the progress of pests and diseases, is conducive to the development of precision management, so that timely detection, timely treatment, but also conducive to early prevention and treatment. The pesticide spraying UAV can spray the pesticides accordingly.
2. Statistical analysis of plant number and seedling rate
Some companies have developed software and mapping solutions for UAV software and provide growth analysis tools for crops. By crop count, Area to analyze whether the current crop is the best growth distance. In addition, users can also use the UAV remote sensing mapping hardware and software technology to analyze the new planted seedling rate to determine the re-planting program.
3. Analyze soil properties
Agricultural remote sensing is a convenient means to promote the standardization of agriculture. In precision agriculture, there is an important concept called the normalized vegetation index.
4. Assessment of crop damage after natural disasters
After natural disasters occur, remote sensing techniques can be used to assess damage after storms and freezing disasters.
5. Overview of terraced fields, easy to correct in time
The terraced field is a stepped farmland built on the slope along the contour line. It is an important soil and water conservation measure. It has the function of keeping water, soil conservation and fertilizer.
Satellite remote sensing has been developed for a long time, but the satellite is susceptible to weather conditions, and the orbital period is longer. In comparison, agricultural UAVs are more flexible and easy to deploy. It is believed that with the UAV platform, sensor and software technology to further enhance the future UAV as satellite and other remote sensing platform to complement the means to help in agriculture to build a more complete monitoring network.
