I-NDVI (I-Normalized Difference Vegetation Index) sisalathiso esisetyenziswa ngokuqhelekileyo ukulinganisa nokubeka iliso kwimpilo yezityalo kunye nokomelela. Ibalwa kusetyenziswa umfanekiso wesathelayithi, olinganisa ubungakanani bokukhanya okubonakalayo kunye nekufutshane ne-infrared ebonakaliswa luhlaza. I-NDVI ibalwa kusetyenziswa i-algorithms ekhethekileyo esetyenziswe kwidatha efunyenwe kwimifanekiso yesathelayithi. Ezi zixhobo zithatha ingqalelo ubungakanani bokukhanya okubonakalayo kunye nokufutshane kwe-infrared kubonakaliswe zizityalo, kwaye usebenzise olu lwazi ukuvelisa isalathiso esingasetyenziselwa ukuvavanya impilo yezityalo kunye nemveliso. Nangona kunjalo, ezinye iinkampani zithengisa iikhamera ze-NDVI okanye izinzwa ezinokuqhotyoshelwa kwiidrone okanye ezinye iimoto zasemoyeni ukuze zibambe imifanekiso ye-NDVI enesisombululo esiphezulu. Ezi khamera zisebenzisa izihluzi ezikhethekileyo ukubamba ukukhanya okubonakalayo kunye nokufutshane kwe-infrared, okunokuthi emva koko kusetyenzwe kusetyenziswa i-NDVI algorithms ukuvelisa iimephu ezineenkcukacha zempilo yezityalo kunye nemveliso.
Iilensi ezisetyenziselwa iikhamera ze-NDVI okanye izinzwa ngokuqhelekileyo zifana neelensi ezisetyenziselwa iikhamera eziqhelekileyo okanye izinzwa. Nangona kunjalo, banokuba neempawu ezithile zokwandisa ukubanjwa kokukhanya okubonakalayo kunye nokufutshane kwe-infrared. Ngokomzekelo, ezinye iikhamera ze-NDVI zingasebenzisa iilensi ezineengubo ezithile zokunciphisa umlinganiselo wokukhanya okubonakalayo ofikelela kwinzwa, ngelixa ukwandisa inani lokukhanya okukufutshane kwe-infrared. Oku kunokunceda ukuphucula ukuchaneka kwezibalo ze-NDVI. Ukongeza, ezinye iikhamera ze-NDVI zinokusebenzisa iilensi ezinobude obugxininisiweyo okanye ubungakanani bokuvula ukuze kulungiswe ukubanjwa kokukhanya kwi-spectrum ekufutshane ne-infrared, okubalulekileyo kwimilinganiselo ye-NDVI echanekileyo. Ngokubanzi, ukhetho lwelensi yekhamera ye-NDVI okanye inzwa iya kuxhomekeka kwisicelo esithile kunye neemfuno, ezifana nesisombululo esifunwayo sendawo kunye noluhlu lwe-spectral.
