25/08/07ʻO nā kiʻi kiʻi kiʻi laina laina i hana ʻia e hopu i nā kiʻi hoʻonā kiʻekiʻe o nā mea e neʻe a mau paha. ʻAʻole like me nā kiʻi paʻi kiʻi maʻamau e kiʻi i ke kiʻi 2D i hoʻokahi ʻike hoʻokahi, kūkulu nā kiʻi kiʻi laina ma ka laina-kūpono no nā noi e like me ka nānā pūnaewele, ka nānā ʻana semiconductor, a me ka hōʻoia hōʻoia.
Hōʻike maʻamau kēia mau pahupaʻikiʻi i hoʻokahi lālani pika (a i ʻole nā lālani he nui i kekahi manawa), a ke hui pū ʻia me kahi kumuhana neʻe a i ʻole ka ʻōnaehana scanning, hiki iā lākou ke hana i nā kiʻi 2D kiʻekiʻe o nā mea o ka lōʻihi. Ma muli o ke ʻano sensor, hoʻohana maʻamau nā kāmela scan line i ka ʻenehana sensor CCD a i ʻole CMOS—e like me ka mea i loaʻa i nā mea he nui.Nā kiʻi paʻi kiʻi CMOS—me CMOS ka mea i koho ʻia ma muli o kona wikiwiki a me ka ikaika o ka ikehu.
He aha ka Line Scan Camera?
Hoʻomaʻamaʻa pinepine ʻia nā kiʻi kiʻi kiʻi laina no ka ʻenehana ma mua o ka hoʻohana ʻana i ka ʻepekema, a loaʻa paha nā palena i nā noi haʻahaʻa haʻahaʻa a i ʻole kiʻekiʻe kiʻekiʻe. ʻO ka walaʻau heluhelu kiʻekiʻe, nā pika liʻiliʻi a me ka haʻahaʻa haʻahaʻa haʻahaʻa hiki ke manaʻo e koi kēia mau pahupaʻikiʻi i nā pae kukui kiʻekiʻe e hāʻawi i kahi SNR hiki ke hana.
Hiki ke hoʻohana ʻia nā kāmela scan line ma ʻelua mau ala mua:
Hopu 1-Dimensional
Hiki ke hopu ʻia ka ʻike hoʻokahi-dimensional, e like me nā noi spectroscopy. Hōʻike pinepine ʻia nā hopena ma ke ʻano kiʻi ma ka polokalamu pahupaʻikiʻi, me ka ikaika ma ka axis y versus camera pixel ma ka x-axis.
Hopu 2-Dimensional
Hiki ke 'scan' ka pahupaʻikiʻi ma o ke kumuhana kiʻi, ma o ka hoʻoneʻe ʻana i ka pahupaʻikiʻi a i ʻole ke kumuhana kiʻi, a hiki ke hana ʻia ke kiʻi 2-dimensional ma ka hopu ʻana i nā ʻāpana 1-dimensional.
Hiki i kēia ʻano kiʻi kiʻi ke kiʻi i nā kiʻi arbitrarily nui i ka ana scan. ʻO ka hiki ke hopu i nā kumuhana i ka neʻe ʻana me ka ʻole o ka neʻe ʻana (a i ʻole nā mea kiʻi ʻoniʻoni ʻōwili) ʻo ia ka mea e hoʻohana pinepine ʻia nā kiʻi kiʻi laina i nā noi ʻoihana, no nā laina hui, ka nānā ʻana i nā kumuhana kiʻi nui, a me nā mea hou aku.
Pehea ka hana ʻana o kahi kiʻi kiʻi kiʻi laina?
Hana pū ka pahupaʻi kiʻi laina me ka mea hoʻoneʻe a i ʻole ka mīkini nānā. Ke hala ka mea ma lalo o ka pahupaʻikiʻi, hopu ʻia kēlā me kēia laina o ke kiʻi i ka manawa. Hoʻohui ʻia kēia mau laina i ka manawa maoli a i ʻole ma o ka polokalamu e hana i kahi kiʻi 2D piha.
Loaʻa nā ʻāpana koʻikoʻi:
● ʻIke 1-Dimensional: ʻO ka lālani hoʻokahi o nā pika.
● Ka hoʻomalu ʻana: ʻO kahi conveyor a i ʻole ka mīkini ʻōwili e hōʻoia i ka neʻe ʻana.
● kukui: ʻO ke kukui laina a i ʻole coaxial pinepine no ka hoʻomālamalama mau ʻana.
Ma muli o ke kūkulu ʻia ʻana o ke kiʻi i kēlā me kēia laina, he mea koʻikoʻi ka synchronization. Inā neʻe like ʻole ka mea a i ʻole ke pio ʻana o ka manawa, hiki ke hoʻololi ʻia ke kiʻi.
Line Scan vs. Area Scan Cameras

I ka pōkole, ʻoi aku ka maikaʻi o nā kāmela scan line i ke kiʻi ʻana i nā mea holo wikiwiki a nui loa. ʻOi aku ka maikaʻi o nā kiʻi paʻi kiʻi ʻāpana no nā noi me nā pahu hopu static a liʻiliʻi paha.
ʻO nā hiʻohiʻona koʻikoʻi o nā kāmela Scan Line
Ke koho ʻana i kahi kāmela scan line, e noʻonoʻo i kēia mau kikoʻī:
● Hoʻoholo: Ka helu o nā pika ma kēlā me kēia laina, e pili ana i ka pae kikoʻī.
● Laina Laina (Hz): Ka helu o nā laina i hopu ʻia i kēlā me kēia kekona—mea nui no ka nānā ʻana i ka wikiwiki.
● ʻAno ʻIke: CMOS (wikiwiki, mana haʻahaʻa) vs. CCD (kiʻekiʻe kiʻi maikaʻi ma kekahi mau hihia).
● Interface: Nā koho hoʻoili ʻikepili e like me GigE, Link Camera, a i ʻole CoaXPress.
● Kūlana Dynamic & Sensitivity: He mea koʻikoʻi no ka nānā ʻana i nā mea me ka ʻōlinolino like ʻole a i ʻole ka hoʻohālikelike.
● kala vs. Monochrome: Hoʻohana nā kāmela kala i nā lālani he nui me nā kānana RGB; Hiki i ka monochrome ke hāʻawi i ka ʻike kiʻekiʻe.

Pehea e kiʻi ai ka pahupaʻi kiʻi laina i nā kiʻi kala?
Hoʻohana maʻamau nā kiʻi kiʻi kiʻi laina kala i nā ʻenekona tri-linear, aia ʻekolu laina like o nā pika, kēlā me kēia me kahi kānana ʻulaʻula, ʻōmaʻomaʻo, a polū paha. I ka neʻe ʻana o ka mea ma mua o ka mea ʻike, hopu kēlā me kēia laina waihoʻoluʻu i kāna kahawai paʻa i ke kaʻina. Hoʻohui ʻia kēia mau mea e hana i kahi kiʻi kala piha. Pono ka hoʻonohonoho pololei ʻana i mea e pale aku ai i ka misalignment kala, ʻoi aku ka nui ma nā wikiwiki kiʻekiʻe.
Pehea e koho ai i ke kiʻi paʻi kiʻi laina pololei
Ke koho ʻana i ka pahupaʻikiʻi kūpono e pili ana i nā koi o kāu noi. Eia kekahi mau kumu nui e noʻonoʻo ai:
● Pono wikiwiki: E hoʻoholo i kāu pono laina laina ma muli o ka wikiwiki o ka mea.
● Pono e hoʻoholo: E hoʻohālikelike i ka ʻōlelo hoʻoholo i kāu mau ʻae ʻana.

Inā kānalua ʻoe, e kamaʻilio me kahi loea ʻike mīkini a mea kūʻai paha e hōʻoia i ka hoʻohālikelike ʻana me kāu hoʻolālā ʻōnaehana a me nā pahuhopu noi.
ʻEhia laina i loaʻa i kahi pahupaʻi kiʻi laina monochrome?
ʻO ka pahu kiʻi kiʻi laina monochrome maʻamau i loaʻa i hoʻokahi laina o nā pika, akā aia kekahi mau hiʻohiʻona i ʻelua mau laina like ʻole. Hiki ke hoʻohana ʻia kēia mau mea ʻike laina nui no ka hoʻomaikaʻi ʻana i ka maikaʻi o ke kiʻi ma o ka hoʻonui ʻana i nā hōʻike he nui, hoʻonui i ka naʻau, a i ʻole ka hopu ʻana i nā kihi kukui like ʻole.
ʻOiai ua lawa nā kāmeʻa laina hoʻokahi no ka nui o ka nānā ʻana i ka wikiwiki, ʻoi aku ka maikaʻi o nā mana ʻelua a me nā laina quad-line i nā kaiapuni koi, ʻoi aku ka nui o kahi haʻahaʻa haʻahaʻa a i ʻole ke kiʻekiʻe ikaika.
No ka aʻo hou aku e pili ana i ka ʻenehana scan line ma nā noi kiʻi liʻiliʻi, e nānā i kā mākou ʻatikala:
