Apparatus and method for Vegetation index detection using multispectral image

摘要

The present invention relates to an apparatus and method for detecting a vegetation index using a multi-spectral image, comprising: an optical module for separating light entering through one or more lenses into image signals of each wavelength band using an image sensor for each wavelength band; a solar radiation measurement module that measures the intensity of sunlight incident from the outside and provides a solar radiation value; an exposure compensation module for adjusting an exposure value of the image sensor for each wavelength band based on the insolation value; When an image signal of each wavelength band is input through an image sensor for each wavelength band to which an exposure value corrected through the exposure compensation module is applied, an inter-pixel correction value of an image of each wavelength band is calculated, and the calculated correction value is used to an image processing module for storing the corrected pixel data and then synthesizing the pixel data to provide a multi-spectral image; and a detection module for calculating a Vegetation Index using the multi-spectral image, and monitoring the type and biophysical state of vegetation in the corresponding area using the calculated vegetation index.
