Research background and significance
A ground object spectrometer is an instrument that uses spectral technology to measure the characteristics of ground objects. It can measure and analyze the reflective characteristics and other characteristics of ground objects. It has a wide range of applications in many fields such as geographic information science, agricultural science, geophysics, etc., mainly used for ground object characteristic analysis and remote sensing data analysis.
Equipment application introduction
1. Crop classification and planting structure analysis
Multi-crop fine identification: Based on the spectral "fingerprints" of different crops (such as the reflectivity differences of rice, corn, and wheat in the near-infrared band), large-scale farmland crop type classification is achieved to assist agricultural statistics and policy formulation.
2. Early detection of pests and diseases: When crops are attacked by pests and diseases, leaf pigments (such as chlorophyll) and cell structures change, and the spectrum shows abnormal absorption in the visible light band (400-700nm), which can detect diseases before the symptoms are observed by the naked eye.
3. Soil salinization and heavy metal pollution monitoring: Indirect assessment of soil salinity through the spectral response of the soil-crop system
