25/08/07Makamera ojambulira mzere ndi zida zapadera zojambulira zomwe zimapangidwa kuti zizijambula zithunzi zowoneka bwino za zinthu zoyenda kapena zopitilira. Mosiyana ndi makamera achikhalidwe omwe amajambula chithunzi cha 2D pakuwonekera kamodzi, makamera ojambulira mzere amapanga zithunzi mzere ndi mzere-oyenera kugwiritsa ntchito monga kuyang'ana pa intaneti, kusanthula kwa semiconductor, ndi kutsimikizira ma phukusi.
Makamerawa amakhala ndi mzere umodzi wa ma pixel (kapena mizere ingapo), ndipo akaphatikizidwa ndi mutu wosuntha kapena makina ojambulira, amatha kupanga zithunzi zapamwamba za 2D za zinthu zautali uliwonse. Kutengera mtundu wa sensa, makamera ojambulira mzere nthawi zambiri amagwiritsa ntchito ukadaulo wa sensa ya CCD kapena CMOS-ofanana ndi zomwe zimapezeka m'malo ambiri.Makamera a CMOS-ndi CMOS kukhala chisankho chokondedwa chifukwa cha liwiro lake komanso mphamvu zake.
Kodi Kamera Yojambulira Mzere Ndi Chiyani?
Makamera ojambulira mzere nthawi zambiri amakonzedwa kuti azigwiritsidwa ntchito m'mafakitale m'malo mogwiritsidwa ntchito ndi sayansi, ndipo amatha kukhala ndi malire pazowunikira pang'ono kapena zolondola kwambiri. Phokoso lowerenga kwambiri, ma pixel ang'onoang'ono komanso kuchita bwino kwambiri kumatha kutanthauza kuti makamerawa amafunikira kuwala kwakukulu kuti apereke SNR yogwira ntchito.
Makamera ojambulira mzere angagwiritsidwe ntchito m'njira ziwiri zazikulu:
1-Dimensional Capture
Zambiri za mbali imodzi zitha kujambulidwa, monga m'mapulogalamu a spectroscopy. Zotsatira nthawi zambiri zimayimiriridwa mu mawonekedwe a graph mu pulogalamu ya kamera, mwamphamvu pa y-axis motsutsana ndi pixel ya kamera pa x-axis.
2-Dimensional Capture
Kamera ikhoza 'kufufuzidwa' pamutu wojambula, kupyolera mukusuntha kamera kapena mutu wojambula, ndipo chithunzi cha 2-dimensional chikhoza kupangidwa pojambula magawo a 1-dimensional motsatizana.
Kujambula kwamtunduwu kumathandizira kujambula zithunzi zazikulu mosasamala mugawo la sikani. Kutha kujambula anthu mukuyenda popanda kusokoneza (kapena zojambula zotsekera) kumatanthauza kuti makamera ojambulira mizere amagwiritsidwa ntchito kwambiri m'mafakitale, popanga mizere, kuyang'anira nkhani zazikulu zojambula, ndi zina zambiri.
Kodi Kamera Yojambulira Mzere Imagwira Ntchito Motani?
Kamera yojambulira mzere imagwira ntchito mogwirizana ndi chinthu chosuntha kapena makina ojambulira. Pamene chinthu chikudutsa pansi pa kamera, mzere uliwonse wa chithunzicho umajambulidwa motsatizana ndi nthawi. Mizere iyi imaphatikizidwa mu nthawi yeniyeni kapena kudzera pa mapulogalamu kuti apange chithunzi chonse cha 2D.
Zigawo zikuluzikulu zikuphatikizapo:
● 1-Dimensional sensor: Nthawi zambiri mzere umodzi wa ma pixel.
● Kuwongolera kuyenda: Makina otumizira kapena ozungulira amatsimikizira kuyenda.
● Kuunikira: Nthawi zambiri kuyatsa kwa mzere kapena coaxial kuti muwunikire mosasintha.
Chifukwa chithunzicho chimamangidwa mzere ndi mzere, kulunzanitsa ndikofunikira. Ngati chinthucho chikuyenda mosagwirizana kapena nthawi yazimitsidwa, kusokonezeka kwa chithunzi kumatha kuchitika.

Mwachidule, makamera ojambulira mizere amapambana pojambula zinthu zomwe zikuyenda mwachangu kapena zazikulu kwambiri. Makamera ojambulira m'dera ali oyenerera kugwiritsa ntchito omwe ali ndi zolinga zazing'ono kapena zokhazikika.
Zofunika Kwambiri za Makamera Ojambula Pamizere
Posankha kamera yojambulira mzere, ganizirani izi:
● Kusankha zochita: Chiwerengero cha ma pixel pamzere uliwonse, kukhudza mulingo watsatanetsatane.
● Mtengo wa Mzere (Hz): Chiwerengero cha mizere yojambulidwa pa sekondi iliyonse—yofunikira pakuwunika kothamanga kwambiri.
● Mtundu wa Sensa: CMOS (yachangu, yotsika mphamvu) motsutsana ndi CCD (mtundu wapamwamba wazithunzi nthawi zina).
● Chiyankhulo: Zosankha zosamutsa deta monga GigE, Camera Link, kapena CoaXPress.
● Dynamic Range & Sensitivity: Zofunikira pakuwunika zinthu zowala mosiyanasiyana kapena zowunikira.
● Mtundu motsutsana ndi Monochrome: Makamera amtundu amagwiritsa ntchito mizere ingapo yokhala ndi zosefera za RGB; monochrome ikhoza kupereka kukhudzika kwakukulu.
