MIPI Camera VS USB Camera

Kusankhidwa kwa mawonekedwe oyenerera bwino kumatengera zinthu zambiri. Ndipo MIPI ndi USB akhalabe awiri mwamakamera otchuka kwambiri. Yendani mozama kudziko la MIPI ndi USB interfaces ndikupeza kufananitsa kwa mawonekedwe.

Pazaka zingapo zapitazi, masomphenya ophatikizidwa asintha kuchokera ku buzzword kupita kuukadaulo wogwiritsiridwa ntchito m'mafakitale, azachipatala, ogulitsa, zosangalatsa, ndi zaulimi. Ndi gawo lililonse la chisinthiko chake, masomphenya ophatikizidwa atsimikizira kukula kwakukulu kwa kuchuluka kwa mawonekedwe a kamera omwe mungasankhe. Komabe, ngakhale kupita patsogolo kwaukadaulo, mawonekedwe a MIPI ndi USB akhalabe mitundu iwiri yodziwika bwino pamawonekedwe ambiri ophatikizidwa.

Kusankhidwa kwa mawonekedwe oyenerera bwino kumadalira zinthu zambiri monga chiwerengero cha chimango / bandwidth, kuthetsa, kudalirika kwa kusamutsa deta, kutalika kwa chingwe, zovuta, ndipo - ndithudi - mtengo wonse. M'nkhaniyi, tiyang'ana ma interfaces onse mwatsatanetsatane kuti timvetse bwino zomwe angathe komanso zolephera zawo.

Kuyang'ana mozama pa MIPI ndi mawonekedwe a USB

 

Kamera ya MIPI si kanthu koma akamera modulekapena dongosolo lomwe limagwiritsa ntchito mawonekedwe a MIPI kusamutsa zithunzi kuchokera ku kamera kupita ku nsanja yolandila. Poyerekeza, kamera ya USB imagwiritsa ntchito mawonekedwe a USB kusamutsa deta. Tsopano, tiyeni timvetsetse mitundu yosiyanasiyana ya MIPI ndi USB yolumikizirana ndi komwe imagwiritsidwa ntchito.

MIPI Interface

MIPI ndiye mawonekedwe omwe amagwiritsidwa ntchito kwambiri pamsika wamasiku ano potumiza zithunzi ndi makanema pakati pa makamera ndi zida zolandirira. Zitha kukhala chifukwa chosavuta kugwiritsa ntchito kwa MIPI komanso kuthekera kwake kuthandizira mitundu ingapo yamapulogalamu apamwamba kwambiri. Imabweranso ndi zida zamphamvu monga 1080p, 4K, 8K ndi kupitilira makanema komanso kujambula kokwezeka kwambiri.

Mawonekedwe a MIPI ndi chisankho chabwino pamapulogalamu monga zida zokwezedwa pamutu, kugwiritsa ntchito mwanzeru magalimoto pamsewu, makina ozindikira ndi manja, ma drones, kuzindikira nkhope, chitetezo, makina owunikira, ndi zina zambiri.

 

MIPI CSI-2 Interface

Muyezo wa MIPI CSI-2 (MIPI Camera Serial Interface 2nd Generation) ndiwowoneka bwino kwambiri, wotchipa, komanso wosavuta kugwiritsa ntchito. MIPI CSI-2 imapereka chiwongolero chachikulu cha 10 Gb/s chokhala ndi mayendedwe anayi azithunzi - njira iliyonse yomwe imatha kusamutsa deta mpaka 2.5 Gb/s. MIPI CSI-2 imathamanga kuposa USB 3.0 ndipo ili ndi ndondomeko yodalirika yogwiritsira ntchito kanema kuchokera ku 1080p mpaka 8K ndi kupitirira. Kuphatikiza apo, chifukwa chakuchepa kwake, MIPI CSI-2 ili ndi bandwidth yazithunzi zapamwamba.

Mawonekedwe a MIPI CSI-2 amagwiritsa ntchito zinthu zochepa kuchokera ku CPU - chifukwa cha mapurosesa ake ambiri. Ndilo mawonekedwe a kamera a Raspberry Pi ndi Jetson Nano. Raspberry Pi kamera ya V1 ndi V2 imakhazikitsidwanso.

Zochepa za MIPI CSI-2 Interface

Ngakhale ndi mawonekedwe amphamvu komanso otchuka, MIPI CSI imabwera ndi zoletsa zochepa. Mwachitsanzo, makamera a MIPI amadalira madalaivala owonjezera kuti agwire ntchito. Zikutanthauza kuti pali chithandizo chochepa cha masensa azithunzi osiyanasiyana pokhapokha opanga makina ophatikizidwa amakankhiradi!

Chiyankhulo cha USB

Mawonekedwe a USB amakhala ngati cholumikizira pakati pa machitidwe awiri - kamera ndi PC. Popeza imadziwika bwino chifukwa cha luso lake la pulagi-ndi-sewero, kusankha mawonekedwe a USB kumatanthauza kuti mutha kutsazikana ndi nthawi zodula, zokokedwa komanso zotsika mtengo zamawonekedwe anu ophatikizidwa. USB 2.0, mtundu wakale, uli ndi zofooka zazikulu zaukadaulo. Pamene teknoloji ikuyamba kuchepa, zigawo zake zingapo zimakhala zosagwirizana. USB 3.0 ndi mawonekedwe a USB 3.1 Gen 1 adakhazikitsidwa kuti athe kuthana ndi malire a USB 2.0 Interface.

USB 3.0 Interface

Mawonekedwe a USB 3.0 (ndi USB 3.1 Gen 1) amaphatikiza zinthu zabwino zamakomedwe osiyanasiyana. Izi zikuphatikizanso kugwirizana kwa pulagi-ndi-sewero ndi kutsika kwa CPU. Mawonekedwe a mafakitale a USB 3.0 amawonjezeranso kudalirika kwake pamakamera apamwamba kwambiri komanso othamanga kwambiri.

Imafunikira zida zowonjezera zochepa ndipo imathandizira bandwidth yotsika - mpaka 40 megabytes pamphindikati. Ili ndi bandwidth yopitilira 480 megabytes pamphindikati. Izi ndizothamanga nthawi 10 kuposa USB 2.0 komanso nthawi zinayi kuposa GigE! Kuthekera kwake kwa pulagi-ndi-sewero kumatsimikizira kuti zida zowoneka bwino zitha kusinthidwa mosavuta - kupangitsa kuti ikhale yosavuta kusintha kamera yowonongeka.

Zochepa za USB 3.0 Interface

Choyipa chachikulu cha mawonekedwe a USB 3.0 ndikuti simungathe kuyendetsa masensa apamwamba kwambiri pa liwiro lalikulu. Kugwetsa kwina ndikuti mutha kugwiritsa ntchito chingwe mpaka mtunda wa mita 5 kuchokera pa purosesa yolandila. Ngakhale zingwe zazitali zilipo, zonse zimakhala ndi "zowonjezera". Momwe zingwezi zimagwirira ntchito limodzi ndi makamera aku mafakitale ziyenera kuyang'aniridwa pa vuto lililonse.
