Field multispectral phenotype imaging system

The vast majority of information about gene expression comes from single plant experiments conducted under controlled environments in greenhouses or climate chambers. Planting plants under different climate and soil conditions will result in different phenotypes compared to individual plants grown in controlled environments. The main reason is that the increase in plant density significantly changes the structure and physiology of plants due to competition for light, nutrients, and water. Another reason is the dynamic response of genotypes to different environments and management. Therefore, the field phenotype of crops should be based on non-destructive measurements at the canopy level, such as measuring light interception, total leaf area, growth rate, and biomass. Based on the above, we will use phenotype as a method for measuring plant dynamic development using visual and remote sensing based growth, structure, and physiological responses. Currently, Videometer has developed a field phenotype called PhenoField that is not affected by wind and different spectral radiationField multispectral phenotype imaging systemUsed to measure spectral and geometric features of the canopy, such as vegetation indices and canopy texture. The system consists of two box structures with a vertically movable external box that can be lowered to the ground and closely attached to the soil surface to eliminate the influence of wind and sunlight. A top centered CCD camera is installed in the internal casing, positioned 2 meters above the ceiling surface. The imaging area is 1.0 m × 1.0 m. An LED light panel is installed in the internal box to generate nine spectral wavelengths as the light source for multispectral images. The interior of the internal box is painted white to obtain diffuse reflection illumination when shading.
