Taw qhia
Txhua lub koob yees duab module uas tawm hauv lub Hoobkas - rau kev kho mob endoscope, lub koob yees duab kev ruaj ntseg, lossis tus neeg tsav tsheb tsis muaj zog - tau raug ntsuas. Calibration ua kom ntseeg tau tias lub module tsim cov duab zoo ib yam, txawm tias qhov sib txawv me me hauv lo ntsiab muag, sensors, thiab sib dhos. Yog tsis muaj nws, ob qhov zoo tib yam-saib modules tuaj yeem muaj xim sib txawv, tsom xam cov ntsiab lus, lossis ci ntsa iab. Rau cov tuam txhab sivOEM Lub Koob Yees Duab Modulecov kev pabcuam, calibration yog ib kauj ruam tseem ceeb. Ntawm Sincere, peb tau tsimcmos module koob yees duabkev daws teeb meem rau ntau tshaj 30 xyoo, thiab calibration yog ib feem ntawm txhua qhov module peb tsim. Kab lus no piav qhia tias kev ntsuas ntsuas yog dab tsi, vim li cas nws tseem ceeb, thiab nws cuam tshuam dab tsi.
Lub Koob Yees Duab Module Calibration yog dab tsi?
Lub koob yees duab modulecalibration ntsuas thiab kho rau variations ntawm optical, hluav taws xob, thiab mechanical yam ntxwv. Cov variations no yog los ntawm:
Lens manufacturing (focal length, centering, distortion)
Sensor variations (rhiab heev, tsaus nti tam sim no, puas pixels)
Kev sib dhos misalignment (lens qaij, ua kom pom tseeb)
Calibration siv cov kev kho - khaws cia rau hauv lub module lub firmware - kom cov duab kawg raws li specifications. Piv txwv li, ibautofocus lub koob yees duab moduleyuav tsum paub qhov twg infinity tsom txoj hauj lwm yog rau txhua chav tsev, vim hais tias lub lens yuav zaum me ntsis siab dua los yog qis dua vim cov kua nplaum tuab.
Vim li cas Calibration thiaj li tsim nyog
| Qhov teeb meem | Tsis muaj Calibration | Nrog Calibration |
|---|---|---|
| Xim raug | Dawb tshuav sib txawv | Cov xim sib xws |
| Ua kom pom tseeb | Autofocus tuaj yeem plam lub ncov siab | Txhim khu kev tsom |
| Distortion | Lub lens khoov tsis raug | Cov kab ncaj nraim nyob ncaj |
| Vignetting | Tsaus fab | Uniform brightness |
| Cov pixels tsis zoo | Bright los yog tsaus nti | Daim ntawv qhia thiab yog |
Hom Calibration
1. Lens thiab Sensor Alignment (Active Alignment)
Cov kauj ruam tseem ceeb tshaj plaws yog aligning lub lens txheeb ze rau lub sensor. Thaum lub sij hawmActive Alignment txheej txheem, lub lens yog txav mus rau hauv rau axes thaum lub sensor ntes ib daim ntawv ntsuam xyuas. Software pom txoj hauj lwm uas sharpness yog maximized thiab ces kaum yog sib npaug. Qhov no yog qhov tseem ceeb rau4K koob yees duab modulesvim tej misalignment ruins ntug nthuav dav. Active alignment kuj muab ib qhoautofocus lub koob yees duab modulepaub pib txoj hauj lwm.
2. Dawb tshuav thiab kho xim
Lub module ntes ib daim npav grey lossis daim duab xim raws li tus qauv teeb pom kev zoo. Lub processor xam cov kev kho kom zoo rau cov liab, ntsuab, thiab xiav raws, khaws cia rau hauv lub cim xeeb. Rau ibai lub koob yees duab modulesiv hauv kev paub txog cov khoom, cov xim zoo ib yam yog qhov tseem ceeb - txwv tsis pub AI tuaj yeem faib cov khoom tsis raug.
3. Lens Shading Correction (LSC)
Lenses feem ntau ua rau cov ces kaum tsaus dua li qhov chaw (vignetting). Calibration ntsuas lub brightness falloff thiab tsim ib tug kho daim ntawv qhia uas brightens lub ces kaum.
4. Geometric Distortion Kho
Wide-angle lo ntsiab muag ua rau lub thoob distortion. Calibration ntsuas tus qauv thiab siv ib qho kev kho software (los yog khw muag khoom tsis siv tom qab).
5. Autofocus Calibration
Rau ibautofocus lub koob yees duab module, tus actuator (VCM) txav lub lens. Calibration ntsuas lub lens txoj hauj lwm (siv lub Hall sensor los yog sib piv cheb) thiab tsim ib daim ntawv qhia ntawm tsav tam sim no thiab tsom mus deb. Qhov no qhia qhov autofocus algorithm raws nraim qhov twg yuav txav mus rau qhov chaw muab lub hom phiaj.
6. Kev kho Pixel tsis raug
TxhuaLub koob yees duab sensor modulemuaj qee qhov pixels tsis zoo (kub, daig, lossis tuag). Calibration txheeb xyuas lawv thiab khaws lawv cov kev tswj xyuas. Lub ISP tom qab ntawd hloov lawv nrog cov txiaj ntsig pixel nyob sib ze - pom tsis tau rau tus neeg siv.
Calibration rau txawv Module Hom
- Autofocus lub koob yees duab module- Xav tau cov kev txwv tsom xam thiab lub rooj tsom-nyob deb.
- AI lub koob yees duab module- Yuav tsum muaj xim zoo ib yam, geometry, thiab sharpness thoob plaws units yog li tus qauv AI tsis xav tau kev cob qhia.
- 4K koob yees duab modules- Kev sib koom ua ke yog qhov yuav tsum tau ua; Lens shading kho yuav tsum tau meej heev.
- CMOS module koob yees duab- Txawm tias cov qauv yooj yim tau txais txiaj ntsig los ntawm kev tshuav dawb thiab kho pixel tsis raug.
Calibration hauv OEM Lub Koob Yees Duab Module Manufacturing
RauOEM Lub Koob Yees Duab Modulentau lawm, calibration yog ua nyob rau hauv txhua txhua module - tsis yog cov qauv. Ib kab ib txwm muaj xws li:
Daim ntawv ntsuam xyuas (xim checker, lub hom phiaj daws teeb meem, thaj chaw uniformity)
Tswj illumination
Calibration software
Ib qho khoom siv uas tuav lub module thiab sib txuas lus ntawm USB lossis MIPI
Lub module's firmware yog hloov kho nrog cov ntaub ntawv calibration. Cov txheej txheem yuav siv li ob peb vib nas this ib module thiab yog tag nrho automated.
