NDVI isobanura Normalized Difference Vegetation Index. Ni igipimo gikunze gukoreshwa mu gusuzuma kure no mu buhinzi mu gusuzuma no gukurikirana ubuzima n'imbaraga by'ibimera.NDVIipima itandukaniro riri hagati y’imirongo itukura n’imirongo hafi ya infrared (NIR) ya electromagnetic spectrum, ifatwa n’ibikoresho byo kureba kure nka satelite cyangwa drones.

Inzira yo kubara NDVI ni iyi:

NDVI = (NIR – Umutuku) / (NIR + Umutuku)

Muri iyi formula, umugozi wa NIR ugaragaza urumuri rwa hafi ya infrared, naho umugozi utukura ugaragaza urumuri rutukura. Agaciro kari hagati ya -1 na 1, aho agaciro kari hejuru kagaragaza ibimera byiza kandi byuzuye, mu gihe agaciro kari hasi kagaragaza ibimera bike cyangwa ubutaka budafite ibara.

Inkuru ya NDVI

NDVI ishingiye ku ihame ry'uko ibimera bizima bigaragaza urumuri rurerure rwa infrared kandi bigafata urumuri rutukura rwinshi. Mu kugereranya imirongo ibiri ya spectral,NDVIishobora gutandukanya neza ubwoko butandukanye bw'ubutaka butwikiriye kandi igatanga amakuru y'ingirakamaro ku bucucike bw'ibimera, imiterere y'imikurire, n'ubuzima muri rusange.

Ikoreshwa cyane mu buhinzi, amashyamba, gukurikirana ibidukikije, n'ahandi mu rwego rwo gukurikirana impinduka mu bimera uko igihe kigenda gihita, gusuzuma ubuzima bw'ibihingwa, kumenya uduce twibasiwe n'amapfa cyangwa indwara, no gushyigikira ibyemezo byo gucunga ubutaka.

Ni gute wakoresha NDVI mu buhinzi?

NDVI ni igikoresho cy'ingirakamaro mu buhinzi mu gukurikirana ubuzima bw'ibihingwa, kunoza imicungire y'umutungo, no gufata ibyemezo bifatika. Dore uburyo bumwe na bumwe NDVI ishobora gukoreshwa mu buhinzi:

Isuzuma ry'Ubuzima bw'Ibihingwa:

NDVI ishobora gutanga ubumenyi ku buzima rusange n'imbaraga z'ibihingwa. Mu gufata buri gihe amakuru ya NDVI mu gihe cy'ihinga, abahinzi bashobora kumenya ahantu hafite ibibazo cyangwa iterambere ribi ry'ibimera. Agaciro ka NDVI gake gashobora kugaragaza ibura ry'intungamubiri, indwara, ikibazo cy'amazi, cyangwa ibyangiritse. Kumenya ibi bibazo hakiri kare bituma abahinzi bafata ingamba zo kubikosora, nko kuhira imyaka, gufumbira, cyangwa kurwanya udukoko.

Ikoreshwa rya NDVI mu buhinzi

Guteganya umusaruro:

Amakuru ya NDVI yakusanyijwe mu gihe cy'ihinga ashobora gufasha kumenya umusaruro w'ibihingwa. Mu kugereranyaNDVIagaciro mu mirima cyangwa mu turere dutandukanye mu murima, abahinzi bashobora kumenya ahantu hashobora gutanga umusaruro mwinshi cyangwa muto. Aya makuru ashobora gufasha mu kunoza itangwa ry'umutungo, guhindura ubucucike bw'ibihingwa, cyangwa gushyira mu bikorwa tekiniki z'ubuhinzi zinoze kugira ngo umusaruro rusange wongererwe.

Gucunga kuhira:

NDVI ishobora gufasha mu kunoza uburyo bwo kuhira. Mu gukurikirana agaciro ka NDVI, abahinzi bashobora kumenya amazi akenewe mu bihingwa no kumenya ahantu hatoserwa cyane cyangwa hadatose neza. Kubungabunga urwego rwiza rw'ubushuhe bw'ubutaka hashingiwe ku makuru ya NDVI bishobora gufasha mu kubungabunga umutungo w'amazi, kugabanya ikiguzi cyo kuhira, no gukumira ikibazo cy'amazi cyangwa amazi menshi mu bimera.

Gucunga ifumbire mvaruganda:

NDVI ishobora kuyobora ikoreshwa ry'ifumbire. Mu kugena agaciro ka NDVI mu murima, abahinzi bashobora kumenya ahantu hakeneye intungamubiri zitandukanye. Agaciro ka NDVI gakomeye kagaragaza ibimera bizima kandi bikura neza, mu gihe agaciro kari hasi gashobora kugaragaza ko intungamubiri zibura. Mu gukoresha ifumbire neza hashingiwe ku ikoreshwa rya NDVI rihindagurika, abahinzi bashobora kunoza ikoreshwa ry'intungamubiri, kugabanya imyanda y'ifumbire, no guteza imbere imikurire y'ibimera iringaniye.

Gukurikirana indwara n'udukoko:NDVI ishobora gufasha mu gutahura indwara cyangwa udukoko hakiri kare. Ibimera bitameze neza akenshi bigaragaza agaciro ka NDVI kari hasi ugereranije n'ibimera bizima. Gukurikirana NDVI buri gihe bishobora gufasha kumenya ahantu hashobora kuba ikibazo, bigatuma habaho ingamba zikwiye zo kurwanya indwara cyangwa ingamba zigamije kurwanya udukoko.

Gushushanya no Gutunganya Imiterere y'Imbuga:Amakuru ya NDVI ashobora gukoreshwa mu gukora amakarita arambuye y'ibimera by'imirima, bigatuma abahinzi bamenya itandukaniro mu buzima bw'ibihingwa n'imbaraga. Aya makarita ashobora gukoreshwa mu gushyiraho uturere ducungwa, aho ibikorwa byihariye, nko gukoresha umusaruro mu buryo buhindagurika, bishobora gushyirwa mu bikorwa hashingiwe ku byo uturere dutandukanye mu murima dukeneye.

Kugira ngo abahinzi bakoreshe neza NDVI mu buhinzi, ubusanzwe bakoresha ikoranabuhanga ryo kumenya kure, nk'amashusho ya satelite cyangwa drones, zifite ibikoresho byo kumenya byinshi bishobora gufata imirongo ikenewe ya spectral. Ibikoresho byihariye bya porogaramu bikoreshwa mu gutunganya no gusesengura amakuru ya NDVI, bigatuma abahinzi bafata ibyemezo bifatika ku bijyanye n'uburyo bwo gucunga ibihingwa.

Ni ubuhe bwoko bw'indorerwamo za kamera zikwiriye NDVI?

Mu gufata amashusho yo gusesengura NDVI, ni ngombwa gukoresha lens za kamera zihariye zikwiriye gufata imigozi ya spectral ikenewe. Dore ubwoko bubiri busanzwe bwa lens zikoreshwa muriNDVIporogaramu:

Ikirahuri cy'urumuri gisanzwe kigaragara:

Ubwo bwoko bwa lenzi bufata spectrum igaragara (ubusanzwe iri hagati ya nanometero 400 na 700) kandi bukoreshwa mu gufata umugozi utukura ukenewe mu kubara NDVI. Lenzi isanzwe igaragara irakwiriye kubera iyo mpamvu kuko yemerera gufata urumuri rutukura rugaragara ibimera bigaragaza.

Ikirahuri cya Near-Infrared (NIR):

Kugira ngo ufate umugozi wa NIR (NIR), ari wo ukenewe mu kubara NDVI, hakenewe lens yihariye ya NIR. Iyi lens yemerera gufata urumuri mu ntera ya infrared (ubusanzwe kuva kuri nanometero 700 kugeza 1100). Ni ngombwa kwemeza ko lens ishoboye gufata neza urumuri rwa NIR idafunguye cyangwa ngo iruhindure.

Amabara y'indorerwamo akoreshwa muri porogaramu za NDVI

Hari ubwo, cyane cyane ku bikoresho by’umwuga byo kureba kure, hakoreshwa kamera za multispectral. Izi kamera zifite sensors nyinshi cyangwa filters zifata imirongo yihariye ya spectral, harimo n’imirongo itukura na NIR ikenewe kuri NDVI. Kamera za multispectral zitanga amakuru nyayo kandi nyayo yo kubara NDVI ugereranije no gukoresha lens zitandukanye kuri kamera isanzwe igaragara.

Ni ngombwa kumenya ko iyo ukoresheje kamera yahinduwe mu gusesengura NDVI, aho akayunguruzo k'imbere ka kamera kasimbuwe kugira ngo gashobore gufata NIR, lens zihariye zakozwe neza kugira ngo zifate urumuri rwa NIR zishobora kuba zidakenewe.

Mu gusoza, NDVI yagaragaje ko ari igikoresho cy'agaciro gakomeye mu buhinzi, gifasha abahinzi kubona ubumenyi bw'ingenzi ku buzima bw'ibihingwa, kunoza imicungire y'umutungo, no gufata ibyemezo bishingiye ku makuru. Bitewe n'uko hakomeje kwiyongera icyifuzo cyo gusesengura neza kandi neza NDVI, ni ngombwa kugira ibikoresho byizewe bifata neza imiyoboro ikenewe ya spectral.

Muri ChuangAn, dusobanukiwe akamaro k'ikoranabuhanga ryo gufata amashusho rifite ireme ryo hejuru mu bikorwa bya NDVI. Niyo mpamvu twishimiye kumenyekanishaIkirahuri cya NDVIes. Yagenewe gukoreshwa mu buhinzi, lenzi yacu yakozwe kugira ngo ifate imigozi itukura n'imirongo iri hafi ya infrared neza kandi isobanutse neza.

Guhindura kamera ya NDVI

Ifite ikoranabuhanga rigezweho ry’ikoranabuhanga n’iry’indorerwamo zigezweho, lensi yacu ya NDVI ituma urumuri rugabanuka, itanga ibisubizo byizewe kandi bihoraho ku mibare ya NDVI. Kuba ihura na kamera zitandukanye kandi byoroshye kuyihuza bituma iba amahitamo meza ku bashakashatsi mu by’ubuhinzi, abahanga mu by’ubuhinzi, n’abahinzi bashaka kuzamura isesengura ryabo rya NDVI.

Ukoresheje lenzi ya NDVI ya ChuangAn, ushobora gufungura ubushobozi bwose bw'ikoranabuhanga rya NDVI, bikaguha imbaraga zo gufata ibyemezo birambuye ku bijyanye no gucunga kuhira, gukoresha ifumbire mvaruganda, kumenya indwara no kunoza umusaruro. Itegereze itandukaniro mu buhanga n'imikorere ukoresheje lenzi yacu ya NDVI igezweho.

Kugira ngo umenye byinshi ku bijyanye na lensi yacu ya NDVI ya ChuangAn no gusesengura uburyo ishobora kunoza isesengura ryawe rya NDVI, sura urubuga rwacu.https://www.opticslens.com/ndvi-lenses-product/.
