Raws li tus qauv zoo tshaj plaws ntawm Raspberry Pi tsev neeg, Raspberry Pi 5 (abbreviated li Pi 5) tau ua tiav qhov kev hloov kho tseem ceeb hauv kev nrhiav tau cov duab. Nws dual MIPI CSI-2 interfaces thiab optimized tsav lub moj khaum txhawb ntau yam ntawm cov ntsiab lus CMOS duab sensors, npog ntau yam xwm txheej los ntawm cov duab yooj yim mus rau AI ntug xam thiab kev yees duab ceev. Los ntawm qhov kev xav paub txog kev tshawb fawb nrov, kab lus no tau txheeb xyuas cov hom, cov yam ntxwv tseem ceeb, thiab cov lus qhia ntawm CMOS sensors txhawb nqa los ntawm Pi 5, muab cov lus qhia rau cov neeg tsim khoom thiab cov neeg nyiam.
I. Hardware Foundation: Lub Core ntawm Sensor Adaptation rau Pi 5
Yog vim li cas vim li cas Pi 5 tuaj yeem sib haum nrog ntau lub CMOS sensors nyob hauv nws cov kho vajtse hloov kho tshiab thiab software ecosystem:
- Nruab nrogdual 22-pin MIPI CSI-2 interfaces(CAM0 thiab CAM1), txhawb kev sib txuas ntawm ob lub koob yees duab. Piv nrog rau yav dhau los 15-pin interface, nws txhim kho cov ntaub ntawv xa tawm bandwidth, ua tau raws li qhov xav tau ntawm siab - daws teeb meem thiab siab -frame-rate duab kis.
- Cov interfaces muab ob lub zog tso tawm ntawm 3.3V thiab 1.8V, yoog rau CMOS sensors nrog cov kev xav tau ntawm lub zog sib txawv, thiab sib xws nrog cov laus 15-pin interface koob yees duab los ntawm adapters.
- Txais covlibcamera driver framework(uas yuav maj mam hloov mus rau rpicam series cov cuab yeej), ib txwm txhawb nqa feem ntau lub ntsiab sensors yam tsis muaj kev txhim kho hauv qab tsav tsheb.
II. Raws li Natively Supported CMOS Sensors
Lub koob yees duab modules launched los ntawm Raspberry Pi officially yog nruab nrog CMOS sensors uas tau undergone nruj compatibility xeem, ua rau lawv nyiam configuration rau Pi 5. Qhov tshwj xeeb tsis muaj raws li nram no:
CMOS Sensor Table
| Sensor Model | Kev daws teeb meem | Nta |
| IMX 219 | 8 MP | Classic nkag-level, xaiv IR lim |
| IMX 477 | 12.3 MP | Txhawb C/CS/M12 lens interfaces, zoo heev low -light performance |
| IMX 708 | 12 MP | Txheem / dav -angle dual versions, xaiv IR lim |
| IMX 296 | 1.6 MP | Ntiaj teb shutter, yam tsawg kawg nkaus raug 30μs |
| IMX 500 | 12.3 MP | Ntawm -chip AI acceleration, txhawb nqa lub hauv paus neural network inference |
| ib 5647 | 5 MP | Thaum ntxov nkag- qauv qauv, txiav tawm |
III. Mainstream Thib Peb-Party Compatible CMOS Sensors
Nrog rau qhov qhib ntawm libcamera tsav lub moj khaum, Pi 5 tuaj yeem sib xws nrog ntau yam thib peb - tog MIPI CSI-2 interface CMOS sensors, txuas ntxiv nthuav dav daim ntawv thov scenarios:
CMOS Sensor Table
| Sensor Series | Cov Qauv Sawv Cev | Cov yam ntxwv tseem ceeb |
| Sony IMX Series | IMX290/327, IMX378, IMX519, IMX462 | Siab rhiab heev, kev siv hluav taws xob tsawg, qee qhov kev txhawb nqa thoob ntiaj teb shutter |
| OmniVision Series | OV 9281/9282, OV 7251 | Feem ntau yog lub ntiaj teb kaw, muaj zog tiag tiag - lub sijhawm ua haujlwm |
| Lwm Cov Qauv Ua Tau Zoo | GC2035, IMX682 | Ua raws li MIPI CSI-2 specification, zoo compatibility |
IV. Cov lus qhia siv tseem ceeb thiab kev xaiv
- System thiab tsav Adaptation: Nws raug nquahu kom siv Raspberry Pi OS (64-ntsis) rau kev sib raug zoo tag nrho. AI sensors xws li IMX500 tsis txhawb Ubuntu systems ib ntus; thib peb-tog sensors zoo li IMX519 xav tau kev teeb tsa ntxiv ntawm cov tsav tsheb muab los ntawm cov tuam ntxhab.
- Dual{0}}Kev teeb tsa lub koob yees duab: Thaum siv ob lub sensors ib txhij, koj yuav tsum tau ntxiv cov cuab yeej ntoo teeb tsa hauv /boot/config.txt, qhia cov qauv sensor sib xws rau CAM0 thiab CAM1 interfaces.
- Scenario-Kev xaiv raws: Xaiv IMX708 rau kev siv txhua hnub, IMX477 rau kev tshaj lij duab zoo, IMX296 rau siab-ceev xwm txheej ceev, IMX500 rau AI inference, thiab IMX219 los yog sib xws thib peb- tog sensors rau qis- cov haujlwm raug nqi.
- Sau ntawv: Siab- daws teeb meem sensors (xws li IMX477) xav tau lub zog ruaj khov; laus 15-pin interface sensors yuav tsum tau txuas nrog los ntawm adapters, thiab yuav tsum tau them nyiaj mloog mus rau tus pin kev sib raug zoo kom tsis txhob muaj kev puas tsuaj ntawm cov cuab yeej.
V. Summary
Los ntawm kev hloov kho kho vajtse interface thiab software ecosystem optimization, Raspberry Pi 5 tau tsim lub CMOS sensor compatibility system uas npog "cov duab yooj yim-cov duab zoo tshaj-AI acceleration-siab-speed photography". Nws tsis tsuas yog txhawb nqa cov qauv ruaj khov nruj xyuas los ntawm cov neeg ua haujlwm tab sis kuj tseem muab qhov chaw hloov pauv hloov tau yooj yim rau thib peb- tog sensors, ua tau raws li qhov xav tau ntau yam los ntawm kev nkag- theem ua haujlwm rau kev txhim kho kev tshaj lij. Nrog kev hloov tshiab tas li ntawm firmware thiab cov tsav tsheb, cov npe ntawm cov sensors txhawb nqa los ntawm Pi 5 yuav nthuav dav ntxiv. Nws raug pom zoo tias cov neeg tsim khoom hloov kho lub kaw lus tsis tu ncua kom tau txais kev txhawb nqa kev sib raug zoo tshiab.
