NDVI (Normalized Difference Vegetation Index) indekisi inowanzoshandiswa kuyera uye kutarisa hutano hwezvinomera uye simba. Inoverengwa pachishandiswa satellite imagery, inoyera huwandu hwechiedza chinooneka uye chiri pedyo-infrared chinoratidzwa nezvinomera. NDVI inoverengerwa ichishandisa algorithms akakosha akaiswa kune data rinowanikwa kubva kumifananidzo yesatellite. Aya maalgorithms anotarisa huwandu hwechiedza chinooneka uye chiri pedyo-infrared chinoratidzwa nezvinomera, uye shandisa ruzivo urwu kugadzira index inogona kushandiswa kuongorora hutano hwezvinomera uye goho. Nekudaro, mamwe makambani anotengesa NDVI makamera kana masensa anogona kusungirirwa kune drones kana dzimwe mota dzemuchadenga kutora yakakwirira-resolution NDVI mifananidzo. Aya makamera anoshandisa mafirita ane hunyanzvi kubata ese ari maviri anooneka uye ari pedyo-infrared mwenje, ayo anogona kuzogadziriswa achishandisa NDVI algorithms kugadzira akadzama mepu dzehutano hwezvinomera uye goho.
Malenzi anoshandiswa kumakamera eNDVI kana masensa anowanzo kufanana nemalenzi anoshandiswa kune akajairwa makamera kana masensa. Nekudaro, ivo vanogona kunge vaine chaiwo maitiro ekugadzirisa kubatwa kweinooneka uye pedyo-infrared mwenje. Semuyenzaniso, mamwe makamera eNDVI anogona kushandisa malenzi ane jira rakati kuti aderedze huwandu hwemwenje unooneka unosvika ku sensor, uku uchiwedzera huwandu hwepedyo-infrared light. Izvi zvinogona kubatsira kuvandudza kurongeka kweiyo NDVI kuverenga. Pamusoro pezvo, mamwe makamera eNDVI anogona kushandisa malenzi ane hurefu hwekutarisa kana saizi yekuvhura kuti agone kubatwa kwechiedza mune iri pedyo-infrared spectrum, izvo zvakakosha kune chaiyo NDVI kuyerwa. Pakazere, sarudzo yelens yeNDVI kamera kana sensor inotsamira pane chaiyo application uye zvinodiwa, senge inodiwa spatial resolution uye spectral renji.
