Kodi mukudabwa momwe mungasankhire pakati pa Rolling shutter ndiChotseka chapadziko lonsepa pulogalamu yanu? Kenako, werengani nkhaniyi kuti mumvetse bwino kusiyana pakati pa rolling shutter ndi global shutter ndi momwe mungasankhire yomwe ikugwirizana bwino ndi pulogalamu yanu.
Makamera amakono a mafakitale ndi makina ojambula zithunzi ali ndi masensa omwe amajambula ndi kujambula zithunzi zosiyanasiyana kuti agwiritsidwe ntchito pokonza ndi kusanthula. Masensawa amagwiritsa ntchito shutter yamagetsi kuti agwire zithunzi. Shutter yamagetsi ndi chipangizo chomwe chimayang'anira kuwonekera kwa zitsime za photon pa sensa. Chimazindikiranso ngati ma pixels ali owonekera mzere ndi mzere kapena ngati matrix yonse. Mitundu iwiri yayikulu ya shutter yamagetsi ndi Rolling shutter ndi Global shutter. Nkhaniyi ikufotokoza njira zotsekera, kusiyana pakati pa ma shutter awiriwa, ndi komwe angawagwiritse ntchito.
Chotsekera chozungulira
Kodi Rolling shutter ndi chiyani?
Kachitidwe kozungulira ka shutter mu kamera kamawonetsa mizere ya ma pixel imodzi pambuyo pa inzake, ndi nthawi yosiyana kuchokera pamzere umodzi kupita ku wina. Poyamba, mzere wapamwamba wa chithunzicho umayamba kusonkhanitsa kuwala ndikumaliza. Kenako mzere wotsatira umayamba kusonkhanitsa kuwala. Izi zimapangitsa kuchedwa kwa nthawi yomaliza ndi yoyambira yosonkhanitsa kuwala kwa mizere yotsatizana. Nthawi yonse yosonkhanitsa kuwala pamzere uliwonse ndi yofanana.
Chotsekera Chozungulira
Kusiyana kwa kujambula pakati pa sensa yozungulira ndi sensa yozungulira kumaonekera kwambiri mukutenga zithunzi zosinthika. Zinthu zoyenda mwachangu zikagwidwa ndi sensa yozungulira, zotsatira za sensa yozungulira zimachitika. Mu sensa yozungulira, ma pixel onse a array mu sensa ya chithunzi samawonekera nthawi imodzi ndipo mzere uliwonse wa ma pixel a sensa umasanthulidwa motsatizana. Chifukwa cha izi, ngati chinthu chikuyenda mofulumira kuposa nthawi yowonekera ndi nthawi yowerenga ya sensa ya chithunzi, chithunzicho chimasokonekera chifukwa cha kuwonekera kwa kuwala kozungulira. Izi zimatchedwa zotsatira za sensa yozungulira.
Chotseka Padziko Lonse
Kodi Global Shutter ndi chiyani?
Chotseka chapadziko lonseMu sensa ya chithunzi, ma pixel onse a sensa amalola ma pixel onse kuyamba kuwonekera ndikusiya kuwonekera nthawi imodzi kwa nthawi yowonetsedwa yokonzedwa panthawi iliyonse yopeza chithunzi. Pambuyo pa nthawi yowonekera, kuwerenga deta ya ma pixel kumayamba ndipo kumapitilira mzere ndi mzere mpaka deta yonse ya ma pixel itawerengedwa. Izi zimapanga zithunzi zosasokonekera popanda kugwedezeka kapena kupotoka. Masensa a shutter padziko lonse nthawi zambiri amagwiritsidwa ntchito kujambula zinthu zoyenda mwachangu.
Kodi sensa ya shutter yapadziko lonse imagwira ntchito bwanji?
Chotsekera chapadziko lonse chimavumbula mizere yonse ya chithunzi nthawi imodzi, 'kuzizira' chinthu choyenda pamalo pake. Izi zimaletsa kusokonekera, zomwe zimapangitsa ukadaulo wa chotsekera chapadziko lonse kukhala chisankho chabwino kwambiri pakugwiritsa ntchito zinthu zoyenda komanso mayendedwe ofulumira, kuphatikizapo kuzindikira kwa chiphaso cha galimoto ngati gawo la kuwunika magalimoto, mwachitsanzo.
Ubwino wa masensa otsekera padziko lonse lapansi:
1. Mitengo yapamwamba ya chimango
2. Kusanja kwakukulu
3. Zithunzi zooneka bwino, ngakhale zitawonetsedwa kwa kanthawi kochepa
4. Makhalidwe abwino kwambiri a phokoso, ngakhale mutakhala ndi kuwala koipa
5. Mitundu yosiyanasiyana yamphamvu
6. Mphamvu yapamwamba ya quantum mpaka 70%
Kodi tikufuna kuti kamera ya shutter yapadziko lonse ndi kamera yozungulira yozungulira?
Kamera ya shutter yapadziko lonse imagwiritsidwa ntchito makamaka kujambula zinthu zoyenda mwachangu popanda zinthu zakale komanso kusokoneza kayendedwe. Makamera a shutter apadziko lonse lapansi amagwiritsidwa ntchito pazinthu monga kutsatira mpira, makina oyendetsera mafakitale, maloboti osungiramo zinthu, ma drones ndi zina zotero.
Ma sensor ozungulira amapereka mphamvu yabwino kwambiri yojambulira zithunzi ndipo angagwiritsidwe ntchito pazinthu zotsika mtengo. Amagwiritsidwa ntchito kwambiri pojambula zinthu zoyenda pang'onopang'ono monga matrakitala a ulimi, ma conveyor othamanga pang'onopang'ono, ndi mapulogalamu odziyimira pawokha monga ma kiosks, ma barcode scanner, ndi zina zotero.
