ʻO NDVI (Normalized Difference Vegetation Index) kahi helu kuhikuhi i hoʻohana pinepine ʻia no ke ana ʻana a me ka nānā ʻana i ke olakino a me ka ikaika o nā mea kanu. Hoʻomaulia ʻia me ka hoʻohana ʻana i nā kiʻi ukali, e ana ana i ka nui o ke kukui ʻike ʻia a kokoke i ka infrared i hōʻike ʻia e nā mea kanu. Hoʻomaulia ʻia ʻo NDVI me ka hoʻohana ʻana i nā algorithms kūikawā i hoʻopili ʻia i ka ʻikepili i loaʻa mai nā kiʻi ukali. Hoʻomanaʻo kēia mau algorithms i ka nui o ke kukui ʻike ʻia a kokoke i ka infrared i hōʻike ʻia e nā mea kanu, a hoʻohana i kēia ʻike e hana i kahi helu kuhikuhi e hiki ke hoʻohana ʻia e loiloi i ke olakino a me ka huahua o nā mea kanu. Eia nō naʻe, kūʻai aku kekahi mau hui i nā kāmela NDVI a i ʻole nā mea ʻike e hiki ke hoʻopili ʻia i nā drones a i ʻole nā kaʻa ea ʻē aʻe e hopu i nā kiʻi NDVI kiʻekiʻe. Hoʻohana kēia mau kāmela i nā kānana kūikawā e hopu i ke kukui ʻike ʻia a kokoke i ka infrared, a laila hiki ke hana ʻia me ka hoʻohana ʻana i nā algorithms NDVI e hana i nā palapala kikoʻī o ke olakino a me ka huahua o nā mea kanu.
ʻO nā aniani i hoʻohana ʻia no nā kāmela a i ʻole nā mea ʻike NDVI ua like ia me nā aniani i hoʻohana ʻia no nā kāmela maʻamau a i ʻole nā mea ʻike. Eia nō naʻe, loaʻa paha iā lākou nā ʻano kikoʻī e hoʻomaikaʻi i ka hopu ʻana o ke kukui ʻike ʻia a kokoke i ka infrared. No ka laʻana, hiki i kekahi mau kāmela NDVI ke hoʻohana i nā aniani me kahi uhi kikoʻī e hōʻemi i ka nui o ke kukui ʻike ʻia e hiki aku ana i ka sensor, me ka hoʻonui ʻana i ka nui o ke kukui kokoke i ka infrared. Hiki i kēia ke kōkua i ka hoʻomaikaʻi ʻana i ka pololei o nā helu NDVI. Eia kekahi, hiki i kekahi mau kāmela NDVI ke hoʻohana i nā aniani me kahi lōʻihi focal kikoʻī a i ʻole ka nui o ka puka e hoʻomaikaʻi i ka hopu ʻana o ke kukui ma ka spectrum kokoke i ka infrared, he mea nui ia no nā ana NDVI pololei. Ma keʻano holoʻokoʻa, ʻo ke koho ʻana o ka aniani no kahi kāmela NDVI a i ʻole sensor e hilinaʻi ʻia i ka noi kikoʻī a me nā koi, e like me ka hoʻonā spatial i makemake ʻia a me ka laulā spectral.
