ʻO ka NDVI (Normalized Difference Vegetation Index) he papa kuhikuhi maʻamau no ke ana a nānā ʻana i ke olakino a me ka ikaika o nā mea kanu. Hoʻohana ʻia ia me ka hoʻohana ʻana i nā kiʻi ukali, kahi e ana i ka nui o nā kukui ʻike ʻia a kokoke-infrared i hōʻike ʻia e nā mea kanu. Ua helu ʻia ʻo NDVI me ka hoʻohana ʻana i nā algorithm kūikawā i hoʻopili ʻia i ka ʻikepili i loaʻa mai nā kiʻi satellite. Noʻonoʻo kēia mau algorithms i ka nui o nā kukui ʻike ʻia a kokoke i ka infrared i hōʻike ʻia e nā mea kanu, a hoʻohana i kēia ʻike e hana i kahi index hiki ke hoʻohana ʻia e loiloi i ke olakino mea kanu a me ka huahana. Eia nō naʻe, ke kūʻai aku nei kekahi mau hui i nā kāmela NDVI a i ʻole nā seni hiki ke hoʻopili ʻia i nā drones a i ʻole nā kaʻa lewa ʻē aʻe e hopu i nā kiʻi NDVI kiʻekiʻe. Hoʻohana kēia mau kāmela i nā kānana kūikawā e hopu i nā 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 mea kanu a me ka huahana.
ʻO nā lens i hoʻohana ʻia no nā kiʻi paʻi kiʻi NDVI a i ʻole nā mea ʻike e like me nā lens i hoʻohana ʻia no nā kāmela maʻamau. Eia nō naʻe, loaʻa iā lākou nā hiʻohiʻona kikoʻī no ka hoʻopaʻa ʻana i ke kukui ʻike ʻia a kokoke i ka infrared. No ka laʻana, hiki i kekahi mau pahupaʻi kiʻi NDVI ke hoʻohana i nā lens me kahi uhi kikoʻī e hōʻemi i ka nui o nā kukui ʻike ʻia e hiki i ka mea ʻike, ʻoiai e hoʻonui ana i ka nui o nā kukui infrared kokoke. Hiki i kēia ke kōkua i ka hoʻomaikaʻi ʻana i ka pololei o nā helu NDVI. Hoʻohui hou, hiki i kekahi mau pahupaʻi kiʻi NDVI ke hoʻohana i nā lens me kahi kikoʻī kikoʻī a i ʻole ka nui ākea e hoʻopaʻa pono i ka hopu ʻana o ka mālamalama i loko o ka spectrum infrared kokoke, he mea nui ia no nā ana NDVI pololei. Ma ke ʻano holoʻokoʻa, ʻo ke koho ʻana o ka lens no kahi kāmela NDVI a i ʻole sensor e hilinaʻi i ka noi kikoʻī a me nā koi, e like me ka hoʻonā spatial i makemake ʻia a me ka laulā spectral.
