Dab tsi yog Qhov Yuav Tsum Tau Rau Raspberry Pi Lub Koob Yees Duab Module?
Ua ntej, muaj cov kev xav tau sib xws rau Raspberry Pi motherboard qauv. Lub Raspberry Pi Lub Koob Yees Duab Module txuas mus rau motherboard ntawm CSI -2 interface, yog li nws yog qhov tsim nyog los xyuas kom meej tias Raspberry Pi motherboard muaj qhov sib xws CSI -2 interface thiab kev txhawb nqa kho vajtse. Cov qauv Raspberry Pi thaum ntxov tsuas yog txhawb nqa 15-pin CSI-2 interface thiab muaj qhov txwv bandwidth thiab suav lub zog txhawb nqa rau siab - daws teeb meem modules. Cov qauv tshiab tau nruab nrog CSI-2 interfaces sai dua thiab tuaj yeem hloov kho rau cov kev daws teeb meem siab, siab-nruab nqi modules. Tsis tas li ntawd, qee cov qauv hauv Raspberry Pi Zero series muaj qhov loj me me CSI-2 interface thiab xav tau ib qho tshwj xeeb mini CSI-2 adapter cable; lawv tsis tuaj yeem siv tus qauv CSI-2 ribbon cables ncaj qha, yog li kev yuav khoom ntxiv ntawm lub adapter cable yog tsim nyog.
Qhov thib ob, muaj cov khoom siv hluav taws xob. Lub Raspberry Pi Lub Koob Yees Duab Module feem ntau ua haujlwm ntawm qhov hluav taws xob ntawm 3.3V, thiab lub zog yog muab ncaj qha los ntawm CSI -2 interface ntawm Raspberry Pi motherboard, tshem tawm qhov xav tau rau lub zog ntxiv. Txawm li cas los xij, nws yog ib qho tseem ceeb los xyuas kom meej lub zog ruaj khov rau Raspberry Pi motherboard: yog tias Raspberry Pi txuas nrog ntau lub siab - siv cov khoom siv hluav taws xob ib txhij, tag nrho cov tam sim no tuaj yeem tshaj qhov muaj peev xwm ntawm lub hwj chim adapter, ua rau muaj qhov hloov pauv ntawm qhov hluav taws xob thiab cov duab tom qab ntawm lub koob yees duab module. Yog li ntawd, nws yog ib qho tsim nyog yuav tau xaiv lub hwj chim adapter nrog lub peev xwm txaus raws li tag nrho cov hwj huam siv ntawm Raspberry Pi kom tsis txhob cuam tshuam rau lub module kev ua haujlwm vim muaj hluav taws xob tsis txaus.
Thaum kawg, muaj cov kev xav tau rau accessories thiab installation. Lub lo ntsiab muag ntawm Raspberry Pi Lub Koob Yees Duab Modules feem ntau yog tshem tau lossis kho tau. Nws yog ib qho tsim nyog los xaiv lub lens tsim nyog raws li daim ntawv thov scenario, thiab thaum lub sij hawm installation, xyuas kom meej tias lub lens yog raws nraim nrog lub sensor kom tsis txhob cov duab misalignment thiab blurriness. Yog tias siv nyob rau hauv cov xwm txheej sab nraum zoov, yuav tsum tau siv cov ntaub thaiv dej kom tsis txhob muaj kev puas tsuaj rau lub module los ntawm nag thiab plua plav. Tsis tas li ntawd, qee qhov modules xav tau kev hloov pauv ntawm Raspberry Pi's I2C interface, yog li nws yog qhov tsim nyog los xyuas kom meej tias I2C muaj nuj nqi ntawm Raspberry Pi tau qhib; txwv tsis pub, cov kev txwv xws li kev tsom xam thiab raug tsis tuaj yeem hloov kho.
Ua ntej, muaj cov kev cai rau kev khiav hauj lwm thiab kev txhawb nqa tsav tsheb. Lub Raspberry Pi Lub Koob Yees Duab Module nyob ntawm qhov kev ua haujlwm Raspberry Pi kev ua haujlwm lossis cov tshuab tau sib xws, thiab nws yog qhov tsim nyog los xyuas kom meej tias qhov system version txhawb nqa module tus tsav tsheb. Cov tshuab thaum ntxov feem ntau txhawb nqa lub tsev qiv ntawv Picamera, thaum cov tshuab tshiab tau hloov mus rau Libcamera tsev qiv ntawv. Siv cov txheej txheem qub los hloov mus rau tus qauv tshiab ntawm lub module yuav ua rau tus neeg tsav tsheb tsis sib haum. Yog li ntawd, nws yog ib qho tsim nyog yuav tau hloov kho Raspberry Pi system mus rau qhov tseeb ruaj khov version thiab hloov kho lub firmware siv cov cuab yeej raug cai los xyuas kom meej tias tus neeg tsav tsheb sib phim cov qauv qauv.
Qhov thib ob, muaj cov kev cai rau cov tsev qiv ntawv software thiab kev txhim kho ib puag ncig. Rau cov duab ntes thiab kev txhim kho, cov tsev qiv ntawv software sib txuas yuav tsum tau teeb tsa: rau Python developers, lub tsev qiv ntawv Picamera2 lossis lub tsev qiv ntawv Picamera yuav tsum tau teeb tsa, uas tuaj yeem ua tiav sai ntawm pip cov lus txib. Rau C/C++ developers, Libcamera development package yuav tsum tau nruab. Ntxiv rau, txhawm rau siv cov haujlwm siab heev, nws tseem yuav tsum tau nruab cov tsev qiv ntawv nyob hauv, xws li OpenCV, FFmpeg, thiab TensorFlow Lite. Cov tsev qiv ntawv no yuav tsum raug xaiv raws li cov khoom siv kho vajtse ntawm Raspberry Pi kom tsis txhob muaj teeb meem kev teeb tsa vim qhov tsis sib xws ntawm architecture.
Ua ntej, muaj cov kev cai rau kev teeb pom kev zoo thiab kev yees duab ib puag ncig. Cov duab sensors ntawm Raspberry Pi Lub Koob Yees Duab Modules kuj me me, ua rau muaj teeb pom kev tsawg -sensing peev xwm. Yog li ntawd, nws yog ib qho tsim nyog los xaiv ib hom qauv tsim nyog raws li qhov xwm txheej: nyob rau hauv cov xwm txheej uas muaj lub teeb pom kev txaus, siv cov xim tsis tu ncua; nyob rau hauv tsawg- teeb los yog tsaus nti, yuav tsum tau siv ib tug NoIR module (tsis muaj ib tug infrared lim) ua ke nrog ib tug infrared sau lub teeb nrog ib tug wavelength ntawm 850nm los yog 940nm. Txwv tsis pub, cov teeb meem xws li lub suab nrov ntau dhau thiab qhov ci ntsa iab yuav tshwm sim. Tsis tas li ntawd, rau siab - kev ua kom pom tseeb, nws yog ib qho tsim nyog los xyuas kom meej lub teeb pom kev zoo kom tsis txhob cuam tshuam qhov sib piv thiab nthuav dav ntawm daim duab.
Qhov thib ob, muaj kev xav tau rau qhov kub thiab txias. Kev khiav hauj lwm kub ntawm Raspberry Pi Lub Koob Yees Duab Modules feem ntau yog 0℃txog 50 degree. Siv lub module nyob rau hauv huab cua kub ib puag ncig tej zaum yuav ua rau kom txo tau sensor kev ua tau zoo los yog txawm puas rau module. Yog li ntawd, kev ntsuas kub yuav tsum tau ua nyob rau hauv ib puag ncig huab cua, xws li txhim kho cov dab dej kub rau lub module lossis siv cov ntaub thaiv npog. Nyob rau tib lub sij hawm, cov ribbon cables thiab interfaces ntawm lub module yog kuj tsis yooj yim sua; ntev - lub sij hawm vibration los yog nquag ntsaws thiab unpluggging tej zaum yuav ua rau kev sib cuag tsis zoo. Yog li, nyob rau hauv qhov teeb meem kev teeb tsa ruaj khov, cov ribbon cables yuav tsum muaj kev ruaj ntseg zoo kom tsis txhob muaj kev puas tsuaj los ntawm sab nraud.
