I. System Overview

The ZD-JKA20 Multispectral Vegetation Monitor is an intelligent sensing device specifically designed for modern agriculture and ecological management. It utilizes visible light and multispectral fusion imaging technology to achieve precise quantitative analysis of vegetation physiological indicators. It can quickly generate various commonly used vegetation index data, such as NDVI, GNDVI, NDRE, OSAVI, LCI, etc. Through intelligent combination analysis of multi-band spectral data, it converts key vegetation growth information into visual data maps, providing scientific decision-making support for precision agriculture, ecological restoration, and other scenarios.
