Use multispectral camera for soil moisture content detection
Multi-spectral cameras can help farmers manage crops, soil, fertilize and irrigate more effectively.By minimizing sprays, fertilizers, wasted water while increasing crop yields, it is of great benefit to farmers and the wider environment.
I. Requirement description
2. Measure irrigation; control crop irrigation by identifying areas suspected of moisture stress, carry out land improvement based on multispectral data, and install drainage systems and waterways.
2. 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
Multi-spectral photography is to capture the same target through multiple lenses with different filters installed, so that they can receive information radiated or reflected by the same target on different narrow spectral bands at the same time, and you can obtain several different spectral bands of the target.photo.

Multi-spectral images can provide more accurate directional information compared to human eye observation. From the above figure, we can see that the soil moisture in experimental farmland first increases and then decreases in the crop growth period, and it decreases significantly in the late crop growth period (Figure 6 Experimental farmland phase six). From the perspective of the spatial distribution of farmland soil moisture, the soil moisture in farmland has uneven spatial distribution in different periods, which is most obvious in the early stage of crop growth (Figure 1).
Yunyi Technology's multi-spectral camera integrates 4 bands (green light, red light, 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 deficiency.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, Measurement of irrigation: Control crop irrigation by identifying areas suspected of water stress, land improvements are carried out based on multispectral data, and drainage systems and waterways are installed.
5. View the damage of agricultural machinery to crops, perform necessary repairs or replace problematic machinery.
