The SDK development library and Demo program are completely open source, providing developers with comprehensive development materials and convenient development
methods.
Close-range observation of plant growth and simultaneous multispectral/visible light imaging comprehensively capture plant shape, texture, spectrum, and other physiological characteristics, providing a data foundation for plant phenotyping research.
Based on spectral differences between crops and the surrounding environment, such as weeds and soil, this system accurately identifies and segments crop seedlings, quantitatively assesses the area of crop plants within a unit area, and calculates regional seedling emergence rates, providing data support for scientific research, breeding, and agricultural seedling replacement.
Based on different vegetation cover scenarios, appropriate vegetation remote sensing indices are selected to analyze growth and cover status, and plant health is assessed based on growth uniformity.
