In recent years, drone technology has achieved remarkable development, making drones no longer limited to the basic functions of aerial photography, but have occupied a place in many fields such as agriculture, forestry, electricity, and reconnaissance. In particular, the new T60 agricultural drone released by DJI has attracted widespread attention.What we want to do today is the multi-spectral aerial survey drone. With its own small and portable, integrated multi-spectral + visible light imaging system and other technical highlights, it is applied to agricultural crop growth monitoring and natural resource survey and exploration, and bringing intelligent progress to agricultural production operations.
The growth process of different crops will be differentiated. For rice fertilizer sprinkling, cotton control, potato spraying foliar fertilizer, etc., drones are used to obtain accurate multispectral images of crops, making agricultural operations more three-dimensional, data-based and intelligent.Multi-spectral drones can efficiently collect crop directional information, help users to have a deeper understanding of crop growth status, and can conduct crop growth analysis, capture abnormal states, and use variable fertilization and medicine.In addition, we can also apply it to environmental monitoring and natural resource surveys such as water eutrophication monitoring, forest distribution survey, urban greening area survey, etc.So how does drones achieve these, the most important thing is that they are equipped with multi-spectral cameras.
Multi-spectral technical requirements:
1. Four spectral channels need to be detected in green band (500-600nm), red band (600-700nm), red edge band (700-730nm), and near-infrared band (700nm-1.3um).
2. Four cameras are shooting in real time synchronously
Working principle of multispectral cameras:
Multi-spectral photography is to capture the same target through multiple lenses with different filters installed, so that it can receive information radiated or reflected by the same target on different narrow spectral bands at the same time, and you can obtain the

Yunkey Technology (
) professional camera solutions are provided. The multi-spectral camera developed by it integrates 4 bands (green, red, red edge and near infrared). All cameras have 2 million pixels and are equipped with global shutters.With just a simple operation, soil volume moisture content and various agricultural testing can be achieved efficiently and quickly.1. Identify pests, diseases and weeds.Optimize pesticide use and crop spray with early detection.
2. Provide data on soil fertility and optimize fertilization by detecting nutritional deficiencies.Help land management, whether to produce or convert crops, etc.
3. Calculate the plant and determine the number of crops or planting spacing issues.Estimate crop yield.
4. Measuring irrigation: Control crop irrigation by identifying areas suspected of water stress, perform land improvement based on multispectral data, and install drainage systems and waterways.
5. Check the damage of agricultural machinery to crops, carry out necessary repairs or replace problematic machinery.
