Taw qhia
A koob yees duab moduleyog ntau tshaj ib tug sensor ntxiv lens. Yuav kom tau txais cov duab zoo tshaj plaws, qis tshaj latency, thiab txhim khu kev qha ua haujlwm, koj yuav tsum saib tag nrho cov yeeb yaj kiab - los ntawm kev xaiv sensor mus rau interface thiab firmware. Txawm koj siv tus qauvHD koob yees duab modulelos yog kev caiOEM koob yees duab module, muaj pov thawj txoj kevoptimize lub koob yees duab module kev ua tau zootsis nce nqi lossis complexity. Cov kab lus no muab cov kauj ruam ua tau zoo tshaj plaws los ntawm kojCMOS Lub Koob Yees Duab Module.
Qhov "Performance" txhais li cas?
Kev ua tau zoo tuaj yeem txhais tau ntau yam:
Kev daws teeb meem siab (nrawm nthuav dav rau kev tshuaj xyuas)
Tsawg-light rhiab heev (ntshiab duab hauv qhov tsaus ntuj)
Tsawg latency (cov lus teb ntawm lub sijhawm rau neeg hlau)
Cov xim tsis sib xws (raug siv kho mob)
Tsawg zog (hnyav roj teeb lub neej)
Txiav txim siab qhov tseem ceeb tshaj plaws rau koj qhov project ua ntej koj pib.
1. Xaiv txoj cai CMOS Lub Koob Yees Duab Module
Lub sensor yog lub hauv paus. ACMOS Lub Koob Yees Duab Modulemuaj zog-npaum thiab sai dua li cov laus CCDs. Kom optimize:
Xaiv lub sensor nrog txoj caipixel loj- loj pixels (Ntau dua los yog sib npaug rau 2.0 µm) muab kev ua tau zoo dua qis-teeb pom kev zoo; me pixels cia siab dua.
Rau qhov tsaus ntuj, siv aBSI (rov qab-illuminated)sensor - nws ntes ntau lub teeb.
Rau cov khoom txav, xaiv antiaj teb shutterkom tsis txhob muaj qhov muag plooj.
IbOEM koob yees duab modulecia koj xaiv qhov tseeb sensor rau koj xav tau, tsis yog ib feem.
2. Muab lub Lens rau lub Sensor
Lub lens yuav tsum daws qhov sensor qhov nthuav dav. Lub siab daws teeb meem sensor nrog lub lens yas pheej yig yuav tsis ntse. Txhim khokoob yees duab module kev ua tau zoo:
Siviav los yog hybrid lo ntsiab muagnrog zoo optical zoo.
Xaiv qhov tsawg txausf-npe(f / 1.8 - f / 2.4) rau koj lub teeb pom kev zoo.
Xaivtsau tsomthaum paub txog kev ua haujlwm deb - nws txuag lub zog thiab qhov chaw. Sivautofocustsuas yog thaum qhov kev ncua deb sib txawv.
Rau ibHD koob yees duab module(1080p), ib qho dlej ntau lub iav lens feem ntau txaus.
3. Kho cov duab teeb liab processor (ISP)
Txawm tias qhov zoo tshaj plaws sensor tuaj yeem tsim cov duab tsis zoo yog tias ISP teeb tsa tsis raug. Rauoptimize kev ua tau zoo:
Khotxo suab nrov- ntau dhau blurs nthuav dav; me ntsis nplooj nplej.
Teebntsemus rau theem uas txhim kho cov npoo tsis muaj halos.
Calibratedawb tshuav nyiaj li casrau koj lub teeb pom kev zoo (xws li, LED, hnub ci). Siv nws pib dawb tshuav nyiaj li cas (AWB) rau cov teeb pom kev sib xyaw.
Pabdynamic ntau yam (WDR)yog tias koj qhov chaw muaj ob qhov chaw kaj thiab tsaus.
NtauCMOS Lub Koob Yees Duab Modulesensors muaj built-in ISP blocks. Rau kev tswj tag nrho, siv cov khoom siv raw-tso tawm thiab ua cov duab ntawm koj tus tswv tsev.
4. Xaiv qhov zoo interface
Lub interface cuam tshuam latency, lub zog, thiab ntev cable. Rauoptimize lub koob yees duab module kev ua tau zoo:
Rau embedded systems, sivMIPI CSI-2- Tsawg latency, tsis tshua muaj zog, kev sib txuas ncaj qha.
Rau cov khoom siv txuas nrog PC,USB(UVC) yooj yim tab sis ntxiv ob peb milliseconds.
For long distances (>5 m), siv Ethernet (GigE) lossis siv USB txuas ntxiv.
IbOEM koob yees duab moduletuaj yeem ua tau nrog lub interface uas haum rau koj cov architecture.
5. Txo latency
Kev siv lub sijhawm tiag tiag (robots, endoscopy) xav tau qis latency. Yuav kom ua tiav nws:
Siv antiaj teb shuttersensor tshem tawm dov shutter ncua.
Hla ISP cov kauj ruam uas tsis tsim nyog (piv txwv li, txo cov suab nrov hnyav) yog tias tus tswv tsev tuaj yeem daws lawv.
XaivMIPIhla USB, thiab zam kev txuas wireless (Wi-Fi ntxiv 20–100 ms).
6. Tswj kev siv hluav taws xob
Rau cov cuab yeej siv roj teeb, kev siv hluav taws xob zoo yog qhov tseem ceeb. Cov txheej txheem muaj xws li:
Sivstandby hom- sensor thiab ISP yuav tsum kos<1 mA when idle.
Txo lubncej tus nqithaum tsis xav tau kev ceev nrawm (piv txwv li, 5 fps rau lub koob yees duab saib xyuas).
Sivthaj tsam ntawm kev txaus siab (ROI)- nyeem tsuas yog ib feem me me ntawm lub sensor, txuag cov ntaub ntawv thiab lub zog.
Rau ibHD koob yees duab moduleat 1080p, aim rau<200 mW active power.
7. Kev sim raws li qhov xwm txheej tiag
Tsis muaj ntau txoj kev xav hloov qhov kev sim tiag tiag hauv ntiaj teb. Siv lub hom phiaj daws teeb meem thiab cov xim checker hauv koj qhov teeb pom kev tiag tiag. Tshawb xyuas:
Nyias hla tag nrho cov duab.
Xim raug tiv thaiv kev siv.
Qhov tob ntawm qhov chaw - puas yog koj qhov kev ua haujlwm nyob deb?
8. Ua hauj lwm nrog kev paub OEM lub koob yees duab Module Chaw tsim tshuaj paus
Cov modules tawm ntawm lub txee yog kev sib haum xeeb. Ua tiagoptimize lub koob yees duab module kev ua tau zoorau koj qhov kev siv tshwj xeeb, xav txog ib qhoOEM koob yees duab module. Ib tus kws tshaj lij tsim khoom tuaj yeem:
