Kev xaiv qhov interface zoo tshaj plaws nyob ntawm ntau yam. Thiab MIPI thiab USB tseem yog ob lub koob yees duab interfaces nrov tshaj plaws. Mus ncig ua si tob rau hauv lub ntiaj teb ntawm MIPI thiab USB interfaces thiab tau txais kev sib piv feature-by-feature.
Tau ob peb xyoos dhau los no, kev pom kev uas siv rau hauv lub koob yees duab tau hloov zuj zus los ntawm ib lo lus nrov mus rau ib qho thev naus laus zis uas siv dav hauv kev lag luam, kev kho mob, kev muag khoom, kev lom zem, thiab kev ua liaj ua teb. Nrog txhua theem ntawm nws txoj kev hloov pauv, kev pom kev uas siv rau hauv lub koob yees duab tau ua kom muaj kev loj hlob ntau ntawm cov koob yees duab interfaces uas muaj rau xaiv. Txawm li cas los xij, txawm tias muaj kev nce qib ntawm thev naus laus zis, MIPI thiab USB interfaces tseem yog ob hom nrov tshaj plaws rau feem ntau ntawm cov ntawv thov pom kev uas siv rau hauv lub koob yees duab.
Kev xaiv lub interface zoo tshaj plaws nyob ntawm ntau yam xws li qhov yuav tsum tau ua ntawm tus ncej / bandwidth, kev daws teeb meem, kev ntseeg tau ntawm kev hloov pauv cov ntaub ntawv, qhov ntev ntawm cable, qhov nyuaj, thiab - tau kawg - tus nqi tag nrho. Hauv tsab xov xwm no, peb saib ob lub interfaces kom meej kom nkag siab zoo dua txog lawv cov peev xwm thiab kev txwv.
720P Lub Koob Yees Duab Module
Saib tob dua ntawm MIPI thiab USB interfaces
Lub koob yees duab MIPI tsis yog dab tsi tab sis ib qholub koob yees duab modulelossis lub kaw lus uas siv MIPI interface los hloov cov duab los ntawm lub koob yees duab mus rau lub platform tswj. Piv txwv li, lub koob yees duab USB siv USB interface rau kev hloov cov ntaub ntawv. Tam sim no, cia peb nkag siab txog ntau hom MIPI thiab USB interfaces thiab qhov chaw uas lawv siv.
MIPI Interface
MIPI yog qhov interface uas siv ntau tshaj plaws hauv kev ua lag luam niaj hnub no rau kev xa duab thiab video ntawm cov koob yees duab thiab cov khoom siv tswj hwm. Nws tuaj yeem yog vim MIPI yooj yim siv thiab nws lub peev xwm los txhawb ntau yam kev siv ua haujlwm siab. Nws kuj tseem muaj cov yam ntxwv muaj zog xws li 1080p, 4K, 8K thiab dhau video thiab kev thaij duab siab.
MIPI interface yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov xws li lub taub hau-mounted virtual reality devices, smart traffic applications, gesture recognition systems, drones, facial recognition, kev ruaj ntseg, surveillance systems, thiab lwm yam.
MIPI CSI-2 Kev Sib Txuas Lus
Tus qauv MIPI CSI-2 (MIPI Camera Serial Interface 2nd Generation) yog ib qho interface uas ua haujlwm tau zoo, pheej yig, thiab yooj yim siv. MIPI CSI-2 muaj qhov siab tshaj plaws ntawm 10 Gb/s nrog plaub txoj kab duab - txhua txoj kab muaj peev xwm xa cov ntaub ntawv txog li 2.5 Gb/s. MIPI CSI-2 ceev dua USB 3.0 thiab muaj ib qho protocol txhim khu kev qha los tswj cov yeeb yaj kiab los ntawm 1080p mus rau 8K thiab dhau ntawd. Tsis tas li ntawd, vim nws cov overhead qis, MIPI CSI-2 muaj qhov net image bandwidth siab dua.
Lub MIPI CSI-2 interface siv tsawg dua cov peev txheej los ntawm CPU - ua tsaug rau nws cov multi-core processors. Nws yog lub koob yees duab interface rau Raspberry Pi thiab Jetson Nano. Lub Raspberry Pi lub koob yees duab module V1 thiab V2 kuj yog raws li nws.
5MP USB Lub Koob Yees Duab Module
Cov kev txwv ntawm MIPI CSI-2 Interface
Txawm hais tias nws yog ib qho interface muaj zog thiab nrov, MIPI CSI muaj qee qhov kev txwv. Piv txwv li, MIPI koob yees duab vam khom cov tsav tsheb ntxiv kom ua haujlwm. Nws txhais tau tias muaj kev txhawb nqa tsawg rau cov duab sensors sib txawv tshwj tsis yog tias cov tuam txhab tsim khoom siv embedded system yeej thawb rau nws!
Kev Sib Txuas Lus USB
Lub USB interface feem ntau yog qhov sib txuas ntawm ob lub tshuab - lub koob yees duab thiab lub PC. Vim tias nws paub zoo txog nws cov peev xwm plug-and-play, kev xaiv lub USB interface txhais tau tias koj tuaj yeem hais lus zoo rau lub sijhawm tsim khoom kim heev thiab siv sijhawm ntev rau koj lub embedded vision interface. USB 2.0, qhov version qub dua, muaj cov kev txwv tseem ceeb. Thaum cov thev naus laus zis pib txo qis, ntau yam ntawm nws cov khoom tsis sib xws. USB 3.0 thiab USB 3.1 Gen 1 interfaces tau tsim tawm los kov yeej cov kev txwv ntawm USB 2.0 Interface.

USB 3.0 Kev Sib Txuas Lus
Lub USB 3.0 (thiab USB 3.1 Gen 1) interface muab cov yam ntxwv zoo ntawm ntau lub interfaces sib txawv. Cov no suav nrog kev sib raug zoo ntawm plug-and-play thiab kev thauj khoom CPU tsawg. Tus qauv kev lag luam pom kev ntawm USB 3.0 kuj ua rau nws muaj kev ntseeg siab rau cov koob yees duab siab thiab cov koob yees duab ceev ceev.
Nws xav tau cov khoom siv kho vajtse tsawg kawg nkaus thiab txhawb nqa bandwidth qis - txog li 40 megabytes ib ob. Nws muaj bandwidth siab tshaj plaws ntawm 480 megabytes ib ob. Qhov no yog 10 npaug sai dua USB 2.0 thiab 4 npaug sai dua GigE! Nws cov peev xwm plug-and-play ua kom ntseeg tau tias cov khoom siv pom kev uas muab tso rau hauv tuaj yeem hloov tau yooj yim - ua rau nws yooj yim los hloov lub koob yees duab puas lawm.
Cov Kev Txwv ntawm USB 3.0 Interface
Qhov tsis zoo tshaj plaws ntawm USB 3.0 interface yog tias koj tsis tuaj yeem khiav cov sensors siab daws teeb meem ntawm qhov ceev ceev. Lwm qhov tsis zoo yog tias koj tsuas yog siv tau ib txoj hlua mus txog qhov deb ntawm 5 meters ntawm tus tswv tsev processor. Txawm hais tias muaj cov hlua ntev dua, lawv txhua tus tau teeb tsa nrog "boosters". Yuav tsum tau kuaj xyuas seb cov hlua no ua haujlwm zoo li cas nrog cov koob yees duab kev lag luam rau txhua tus neeg.
