I-NDVI imi kwisalathiso somhlaba oqhelekileyo. Isalathiso esiqhele ukusetyenziswa kwimvakalelo ekude kunye nezoLimo yokuvavanya nokubeka iliso kwimpilo kunye nobubi bohlaza.I-NVVIAmanyathelo umahluko phakathi kwe-Bod kunye ne-New-Inrad-Inner (NIR) ye-ENGROMAGT SINTTRUMS, ethi ifakwe izixhobo ezikude ezinjengesatellite okanye i-drones.

Ifomula yokubala i-NVVI yile:

I-NVVI = (i-NIR-Red) / (hir + ibomvu)

Kule fomula, iqela le-NIR libonisa ukugxininiswa kwe-infrared ekufuphi, kwaye ibhendi ebomvu imele i-Red. Amaxabiso aqala ukusuka -1 ukuya kwi-1, ngamaxabiso aphezulu abonisa impilo kunye nezityalo ezixineneyo, ngelixa amaxabiso asezantsi amele uhlaza okanye umhlaba ongenanto.

I-NDVI le-NDVI

I-NDVI isekwe kumgaqo wokuba uhlaza olusempilweni lubonakalisa ukukhanya okufuphi ne-infrared okufuphi nokufumana ukukhanya okubomvu. Ngokuthelekisa amaqela amabini abonakalayo,I-NVVIUnokwahlula ngokukuko phakathi kweentlobo ezahlukeneyo zekhava yomhlaba kwaye unikezele ngolwazi oluxabisekileyo malunga nokuxinana kwezityalo, iipateni zokukhula, kunye nempilo epheleleyo.

Isetyenziswa ngokubanzi kwezolimo, amahlathi, ukubeka esweni kwendalo, kunye namanye amabala okubeka esweni utshintsho kwizityalo ngokuhamba kwexesha, vavanya impilo echaphazelekayo yimbalela okanye izifo, kunye nokuxhasa izigqibo zolawulo lomhlaba.

Ungayisebenzisa njani i-NVI kwezoLimo?

I-NDVI sisixhobo esibalulekileyo kwezolimo sokubeka impilo yezityalo, ukulawulwa kwezixhobo ezifanelekileyo, kunye nokwenza izigqibo ezizolwazi. Nazi ezinye iindlela ze-NVVI ezinokusetyenziswa kwezolimo:

Uvavanyo lwezempilo lwesityalo:

I-NVVI inokubonelela ngengqondo kwimpilo yonke kunye namandla okukhula kwezityalo. Ngokufaka idatha ye-NDVI nge-NDVI ixesha lokukhula, amafama anokuchonga iindawo zoxinzelelo okanye uphuhliso lwezityalo olubi. Ixabiso eliphantsi le-NDVI linokubonakalisa ukusilela kwesondlo, izifo, uxinzelelo lwamanzi, okanye umonakalo wezifuno. Ukufunyanwa kwangoko kwale micimbi kuvumela amafama ukuba athathe amanyathelo okulungisa, njengokunkcenkceshela, ukuchumisa, okanye ukulawula izinambuzane.

Ukusetyenziswa kwe-NDVI kwezoLimo

Uqikelelo:

Idatha ye-NDVI iqokelelwe kulo lonke ixesha lokukhula linokunceda ukuqikelela isivuno sesityalo. NgokuthelekisaI-NVVIamaxabiso onke amasimi awahlukeneyo okanye imimandla ngaphakathi kwentsimi, amafama akwazi ukubona iindawo ezinesivuno esiphezulu okanye esisezantsi. Olu lwazi lunokunceda ekuthini ukwabiwa kwezixhobo, ukutshintsha uxinano lokutyala, okanye ukusebenzisa ubuchwephesha bokulingwa ngokuchanekileyo ukwandisa imveliso ngokubanzi.

Ulawulo lokunkcenkceshela:

I-NVI inganceda ekusebenziseni iindlela zokunkcenkceshela. Ngokubeka iliso kwi-NDVI amaxabiso e-NDVI, amafama anokumisela iimfuno zamanzi zezityalo kwaye ichonge iindawo zokunkcenkceshela okanye ezingaphantsi. Ukugcina amanqanaba okufuma komhlaba osekwe kwidatha ye-NDVI anokukunceda ukugcina izixhobo zamanzi, ukunciphisa iindleko zokunkcenkceshela, kunye nokuthintela uxinzelelo lwamanzi okanye i-tersting kwizityalo.

Ulawulo lwechumiso:

I-NVVI inokukhokela isicelo sesichumisi. NguMgangatho we-Meppe NDVI Ixabiso kwintsimi, amafama akwazi ukubona iindawo ezinemfuno ezongezekayo zesondlo. Amaxabiso aphezulu e-NDVI abonisa uhlaza oluhlala lusempilweni, ngelixa amaxabiso asezantsi anokubonisa ukusilela kwesondlo. Ngokusebenzisa izichumisi ngokusekwe ngokuthe ngqo kwisicelo esikhethekileyo se-NDVIP, amafama anokuphucula ukusetyenziswa kwesondlo, ukunciphisa inkunkuma ye-thortilizer, kunye nokukhuthaza ukukhula kwezityalo.

Isifo kunye ne-Pest Hownist:I-NDVI inganceda ekufumanekeni kwangethuba kwezifo okanye izifuno ezinamava. Izityalo ezingenampilo zihlala zibonisa amaxabiso asezantsi e-NDVI xa kuthelekiswa nezityalo ezisempilweni. Ukubeka iliso kwi-NDVI rhoqo kunokunceda ukuchonga iindawo ezinokubakho, ukuvumela ungenelelo ngexesha elifanelekileyo malunga neendlela zolawulo lwezifo ezifanelekileyo okanye amanyathelo athatyathiweyo echibini.

Imephu yensimi kunye ne-zoning:Idatha ye-NDVI inokusetyenziselwa ukwenza iimephu ezineenkcukacha zemihlaba, ivumela amafama ukuba achonge umahluko kwimpilo yezityalo kunye namandla. Ezi mephu zingasetyenziselwa ukwenza imimandla yolawulo, apho iintshukumo ezithile, ezinjengokusetyenziswa kwexabiso lezinto ezifakiweyo, zinokuphunyezwa ngokusekwe kwiimfuno ezithile zeenkalo ezahlukeneyo ezisentsimini.

Ukusebenzisa ngokufanelekileyo i-NDVI kwezoLimo, amafama axhomekeke kwitekhnoloji yokuqonda okude, njengokufana nemifanekiso yesatellite okanye i-drones, ixhotywe ngeenzwa ezifanelekileyo zokufaka iindidi ezifunwayo. Izixhobo zesoftware ezikhethekileyo zisetyenziselwa ukwenza kwaye zihlalutye idatha ye-NDVI, ivumela amafama ukuba enze izigqibo ezinolwazi malunga neendlela zokulawulwa kwezityalo.

Luhlobo luni lweencwadana zekhamera ezifanelekileyo kwi-NDVI?

Xa ukufaka imifanekiso yohlalutyo lwe-NDVI, kubalulekile ukusebenzisa iilensi zekhamera ezifanelekileyo zokufaka iibhendi ezifunwayo. Nazi iintlobo ezimbini eziqhelekileyo zeelensi ezisetyenziselwaI-NVVIIzicelo:

I-lens ebonakalayo ebonakalayo:

Olu hlobo lwelensi luthintela imbonakalo ebonakalayo (iqhele ukusukela kwi-400 ukuya kwi-700 ukuya kwi-700 i-nanometers) kwaye isetyenziselwa ukufaka ibale iqela elibomvu le-NDHI efunekayo kwi-NDHI CUATE. Ilensi ebonakalayo ebonakalayo ilungele le njongo njengoko ivumela ukufaka ukukhanya okubomvu okubonakalayo.

I-infrared-infrared (NIR) lens:

Ukufaka i-infrared ye-infrared (i-NIR) ye-Inf), ebaluleke kakhulu kwi-NDHI ukuba ukubala, iilensi ze-nan ze-Nir ezizodwa ziyafuneka. Le lens ivumela ukuba ifake ukukhanya kwindawo ekufutshane ye-infrared (iqhele ukusukela kwi-700 ukuya kwi-1100 i-nanometers). Kubalulekile ukuba kuqinisekiswe ukuba ilensi iyakwazi ukuthoba ngokuchanekileyo i-NIR ngaphandle kokucoca okanye ukulungisa.

Iilensi ezisetyenziselwa izicelo ze-NDVI

Ngamanye amaxesha, ngakumbi kwizicelo zokuziva ezikude, iikhamera ezikulindelekile. Ezi khamera zixhotyiswe ngeenzwa ezininzi okanye iifilitha ezithimba izibhengezo ezibonakalayo ezibonakalayo, kubandakanya ne-bod kunye ne-NIR efunekayo kwi-NDVI. Iikhamera ezimlinganayo zibonelela ngedatha echanekileyo nechanekileyo yokubala kwe-NDVI xa kuthelekiswa nokusebenzisa iileyi ezahlukeneyo kwikhamera ebonakalayo ebonakalayo.

Kufanelekile ukuba uqaphele ukuba xa usebenzisa ikhamera ye-NDVI ekuhlaziyiweyo, apho icebo leefiltha zangaphakathi zekhamera lithathelwe indawo ukuvumela ukubanjwa, iilensi ezithile ezilungiselelwe ukufakwa ekuthinteleni i-NIR ayinakuyimfuneko.

Ukuququmbela, I-NDVI iqinisekisiwe ukuba sisixhobo esibonakalayo sezolimo, sibenza amafama ukuba afumane ulwazi olunzima kwimpilo yezityalo, enze izigqibo eziqhutywa idatha. Ngemfuno eqhubekayo yokukhula kwe-NVI ngokuchanekileyo nangokufanelekileyo, kubalulekile ukuba ube nezixhobo ezithembakeleyo ezithimba iibhendi ezifunekayo ngokuchaneka.

EChiangan, siyakuqonda ukubaluleka kwetekhnoloji yokucinga ephezulu kwizicelo ze-NDVI. Kungenxa yoko le nto sizingca ngokwazisa bethuI-NDVI Lenses. Yenzelwe ngokukodwa ukusetyenziswa kwezolimo, ilensi yethu inikiwe ukuba ifake iibhendi ezibomvu nezikufuphi ne-infraed angeniselwano ngokulinganayo kunye nokucaciswa.

Ukuguqulwa kwekhamera ye-NDVI

Inemigangatho yokutsala i-ofting kunye neelensi eziphambili, i-lens yethu ye-NDVI iqinisekisa ukugqwetha okuncinci, ukuhambisa iziphumo ezinokuthenjwa nezingaguqukiyo zobalo lwe-NDVI. Ukuhambelana kwamanani eekhamera kunye nokudityaniswa kwayo ngokulula kwenza ukhetho olufanelekileyo kubaphandi bezolimo, i-agromist, kwaye amafama afuna ukuphakamisa uhlalutyo lwabo lwe-NDVI.

Nge-chiangan ye-chiangan's ye-hiangan ye-hiangan, ungavula amandla apheleleyo etekhnoloji ye-NDVI, ukukuxhobisa ukuba wenze izigqibo ezinolwazi malunga nolawulo lokunkcenkceshela, isicelo sesichumisi, kunye nokuphuculwa kwesivuno. Vala umahluko kubo ngokuchanekileyo nangokwenzakala kunye ne-Artional yethu ye-Art ye-Art ndlovi.
