I-NDVI imele inkomba yemicimbi ejwayelekile yemihluko. Kuyinkomba esetshenziswa kakhulu ekuzwa okukude nezolimo ukuhlola nokuqapha impilo kanye nobungqabavu bezimila.NDVIKukala umehluko phakathi kwamabhendi abomvu futhi asondele-infrared (NIR) we-electromagnetic spectrum, etholwa ngamadivayisi wokuzwa okukude njengama-satellites noma ama-drones.

Ifomula yokubala i-NDVI yile:

I-NDVI = (NIR - RED) / (NIR + Red)

Kule formula, i-NIR band imele izibalo eziseduze ze-infrared, futhi i-Red band imele isibalo esibomvu. Amanani asuka ku-1 kuye ku-1, anamanani aphezulu akhombisa izitshalo ezinempilo futhi ezinobukhulu, ngenkathi amanani aphansi amelela imifino ephansi noma emhlabathini ongenalutho.

Inganekwane ye-NDVI

INDVI isuselwa emgomeni wokuthi izimila ezinempilo zibonisa ukukhanya okusondele kakhulu futhi zithola ukukhanya okubomvu okwengeziwe. Ngokuqhathanisa amabhande amabili abukeli,NDVIIngahlukanisa ngempumelelo phakathi kwezinhlobo ezahlukene zesembozo somhlaba futhi zinikeze imininingwane ebalulekile mayelana nobukhulu bezimila, amaphethini okukhula, kanye nempilo yonke.

Kusetshenziswa kabanzi kwezolimo, amahlathi, ukuqapha imvelo, kanye nezinye izinkambu ukuqapha ushintsho ezimihleni ngokuhamba kwesikhathi, zihlole impilo yezitshalo, zihlose izindawo ezithintekile ngesomiso noma isifo sokusekela umhlaba.

Ungayisebenzisa kanjani i-NDVI kwezolimo?

I-NDVI iyithuluzi elibalulekile kwezolimo lokuqapha impilo yezitshalo, ukulungiselela ukuphathwa kwezinsizakusebenza, kanye nezinqumo ezinolwazi. Nazi izindlela ezithile ze-NDVI ezingasetshenziswa kwezolimo:

Ukuhlolwa Kwezempilo Crop:

I-NDVI inganikeza ukuqonda okwezempilo jikelele kanye nobungqabavu bezilimo. Ngokuthwebula njalo idatha ye-NDVI ngaphezulu kwesizini ekhula, abalimi bangakhomba izindawo zokuxineka noma ukuthuthukiswa kwezitshalo ezingezinhle. Amanani we-NDVI aphansi angakhombisa ukushiyeka kwezakhi zomzimba, izifo, ukucindezelwa kwamanzi, noma ukulimala kwezinambuzane. Ukutholwa kusenesikhathi kwalezi zinkinga kuvumela abalimi ukuthi bathathe izinyathelo zokulungisa, njengokunisela okuhlosiwe, umanyolo, noma ukulawulwa kwezinambuzane.

Ukusetshenziswa kwe-NDVI kwezolimo

Ukubikezela ukubikezela:

Idatha ye-NDVI eqoqwe kuyo yonke inkathi yokukhula ingasiza ukubikezela isivuno sezilimo. NgokuqhathanisaNDVIamanani emikhakheni ehlukene noma izifunda ngaphakathi kwensimu, abalimi bangakhomba izindawo ezinezithelo eziphakeme noma eziphansi ezingaba khona. Lolu lwazi lungasiza ekwakheni ukwabiwa kwezinsizakusebenza, ukuguqula ukutshala kokutshala, noma ukusebenzisa amasu wokulima anembile ukuze wandise umkhiqizo jikelele.

Ukuphathwa kokunisela:

I-NDVI ingasiza ekwakheni kahle kokunisela. Ngokuqapha amanani we-NDVI, abalimi banganquma izidingo zamanzi zezilimo futhi bakhombe izindawo ezingaphezudlwana noma ngaphansi kokunisela. Ukugcina amazinga asemsangi onamandla wenhlabathi kususelwa kudatha ye-NDVI kungasiza ukonga izinsiza zamanzi, kunciphise izindleko zokunisela, futhi uvikele ukucindezelwa kwamanzi noma ukufakwa kwamanzi ezitshalweni.

Ukuphathwa komanyolo:

I-NDVI ingaqondisa uhlelo lomanyolo. Ngokuthola amamephu we-NDVI ngaphesheya kwensimu, abalimi bangakhomba izindawo ezinezidingo ezahlukahlukene zezakhi. Amanani aphezulu we-NDVI akhombisa izimila ezinempilo futhi ezikhula ngamandla, ngenkathi amanani aphansi kungaphakamisa ukusilela kwezakhi zomzimba. Ngokusebenzisa umanyolo ngokusekelwe kuhlelo lokusebenza lwe-NDVI-Guided Rate Appares, abalimi bangathuthukisa ukusebenza kahle kwezakhi zomsoco, banciphise imfucuza yomanyolo, futhi bakhuthaze ukukhula kwezitshalo okulinganiselayo.

Izifo Ukuqapha izinambuzane:I-NDVI ingasiza ekutholweni kusenesikhathi kwezifo noma izinambuzane. Izitshalo ezingenampilo zivame ukukhombisa amanani aphansi we-NDVI ngokuqhathaniswa nezitshalo ezinempilo. Ukuqapha ejwayelekile kwe-NDVI kungasiza ekuboneni izindawo eziyinkinga ezingaba khona, okwenza ukungenelela okufika ngesikhathi ngamasu afanele okulawulwa kwezifo noma izindlela zokulawula izinambuzane ezihlosiwe.

I-Field Maple and Soning:Idatha ye-NDVI ingasetshenziswa ukudala amamephu wemifino eningiliziwe yamasimu, avumele abalimi bakwazi ukubona ukuhlukahluka kwezempilo kanye nobungqabavu. Lawa mamephu angasetshenziswa ukudala izindawo zokuphatha, lapho izenzo ezithile, ezinjengezinga lokufaka lokufaka, zingasebenza ngokususelwa kwizidingo ezithile zezindawo ezahlukahlukene ngaphakathi kwensimu.

Ukuze usebenzise ngempumelelo i-NDVI kwezolimo, abalimi ngokuvamile bathembela kubuchwepheshe obude bokuzwa, njengezithombe ze-satellite noma ama-drones, ahlomele izinzwa ze-multispectral ezikwazi ukubamba amabhande abukeli adingekayo. Amathuluzi wesoftware akhethekile asetshenziselwa ukucubungula futhi ahlaziye idatha ye-NDVI, evumela abalimi ukuthi benze izinqumo ezinolwazi mayelana nezitshalo zokuphatha izitshalo.

Hlobo luni lwamalensi wekhamera alungele i-NDVI?

Uma kuthumba izithombe zokuhlaziywa kwe-NDVI, kubalulekile ukusebenzisa ama-lens athile wekhamera alungele ukuthwebula amabhande adingekayo. Nazi izinhlobo ezimbili ezijwayelekile zamalensi ezisetshenziselwaNDVIIzicelo:

I-Lens Ejwayelekile Ebonakalayo Ebonakalayo:

Lolu hlobo lwamalensi luthwebula i-spectrum ebonakalayo (imvamisa esukela kuma-nanometers angama-400 kuya kwayi-700) futhi isetshenziselwa ukuthwebula ibhendi ebomvu edingekayo ukuze kubalwe kwe-NDVI. Ilensi elula ebonakalayo ebonakalayo ilungele le njongo njengoba ivumela ukuthwebula ukukhanya okubomvu okubonakalayo okubonisa izitshalo.

I-Lens esondele (NIR):

Ukuthwebula ibhendi ye-infrared infrared (NIR), ebalulekile ekubalweni kwe-NDVI, kudingeka i-NIR Lens ekhethekile. Le lens ivumela ukuthwebula ukukhanya ebangeni eliseduze le-infrared (ngokuvamile kusuka kuma-nanometers angama-700 kuya kwayi-1100). Kubalulekile ukuqinisekisa ukuthi ilensi iyakwazi ukubamba ngokunembile ukukhanya kwe-NIR ngaphandle kokuhlunga noma ukuyihlanekezela.

Amalensi asetshenziselwa izinhlelo ze-NDVI

Kwezinye izimo, ikakhulukazi ukuthola izicelo zokuzwa okukude kahle, amakhamera we-multispectral asetshenziswa. Lawa makhamera afakwe izinzwa eziningi noma izihlungi ezithwebula amabhendi athile abukekayo, kufaka phakathi ama-band abomvu nakwa-nir adingekayo kwi-NDVI. Amakhamera we-Multispectral anikezela ngedatha enembile futhi eqondile yokubala ye-NDVI ngokuqhathaniswa nokusebenzisa ama-lens ahlukile kwikhamera ebonakalayo ebonakalayo ekhangayo.

Kuhle ukuqaphela ukuthi lapho usebenzisa ikhamera elungisiwe yokuhlaziywa kwe-NDVI, lapho kufakwe khona isihlungi sekhamera sangaphakathi ukuze kuvunyelwe ukuthwebula i-NIR, amalensi athile athuthukiselwe ukukhanya kwe-NIR kungadingeka.

Ekuphetheni, I-NDVI ifakazele ukuthi iyithuluzi elikhulu kwezolimo, enika abalimi ukuthola ukuqonda okubucayi empilweni yezitshalo, bandisa ukuphathwa kwezinsiza, futhi benze izinqumo eziqhutshwa ngedatha. Ngesidingo esanda njalo sokuhlaziywa kwe-NDVI okunembile nangobuciko, kubalulekile ukuba nemishini ethembekile edonsa amabhande afanelekile ngokunemba.

EChuangan, siyakuqonda ukubaluleka kobuchwepheshe obusezingeni eliphezulu lokucabanga ngezicelo ze-NDVI. Kungakho siziqhenya ngokwethula kwethuNDVI Lenses. Yakhelwe ngokukhethekile ukusetshenziswa kwezolimo, ilensi yethu inenjinizo yokuthwebula amabhendi abomvu nawaseduze asondele ngokunemba nokucaca.

Ukuguqulwa kwekhamera ye-NDVI

Okubandakanya ama-opics we-cutting-opting kanye ne-lens ethuthukisiwe, i-NDVI Lens yethu ethuthukisiwe iqinisekisa ukuhlanekezela okukhanyayo okuncane, ukuletha imiphumela ethembekile futhi engaguquki yezibalo ze-NDVI. Ukuhambisana kwalo ngohla lwamakhamera kanye nokuhlanganiswa kwayo okulula kwenze kube yisinqumo esihle sabaphenyi bezolimo, izazi zezolimo kanye nabalimi abafuna ukuphakamisa ukuhlaziywa kwabo kwe-NDVI.

Nge-Chuangan's NDVE Lens, ungavula amandla aphelele we-NDVI Technology, ukukunikeza amandla okwenza izinqumo ezinolwazi ngokwengeziwe mayelana nokuphathwa kokunisela, isicelo somanyolo, ukutholwa kwezifo, nokutholwa kwezifo, nokutholwa kwezifo, nokutholwa kwezifo kanye nokuthola amandla. Izwa umehluko ekuqondeni nasekusebenzeni nge-NDVE lens yethu ye-NDVI.
