typical applicationTypical application

Plant Phenotype ResearchClose observation of plant growth status and simultaneous multi-spectral/visible light imaging, comprehensive acquisition of plant shape, texture, spectrum and other physiological characteristics, providing a data basis for plant phenotype research.
Vegetation Coverage MonitoringBased on the spectral differences between crops and weeds, soil and other environments, the precise identification and plant segmentation of crop seedlings can be completed, the area of crop plants in a unit area can be quantitatively evaluated, and the regional emergence rate can be calculated to provide data support for scientific research and breeding, farming seedling supplementation, etc.
Plant Health AssessmentBased on different vegetation coverage scenarios, the corresponding and applicable vegetation remote sensing index is selected, and the growth and coverage status are analyzed, and the plant health is evaluated by the growth uniformity traits.
