Taw qhia
Koj puas tau ua yeeb yaj kiab thaum taug kev, tsuas pom qhov muag plooj lossis tshee? Qhov ntawd yog lub koob yees duab txav.Duab stabilizationyog thev naus laus zis uas txo qhov muag plooj tshwm sim los ntawm kev co tes, kev co, lossis kev txav. Nws yog ib qho tseem ceeb rau handheld endoscopes, drones, robotic caj npab, thiab automotive koob yees duab. Ntawm Sincere, peb tau tsimcmos module koob yees duabkev daws teeb meem rau ntau tshaj 30 xyoo, suav nrogme koob yees duab modulethiabusb koob yees duab moduletsim nrog stabilization nta. Kab lus no piav qhia txog kev txhim kho cov duab zoo li cas, nws ua haujlwm li cas, thiab qhov twg nws siv.
Image Stabilization yog dab tsi?
Image stabilization (IS) them nyiaj rau lub koob yees duab tsis xav tau los tsim cov duab ntse dua thiab cov yeeb yaj kiab smoother. Ob hom loj:
Optical Image Stabilization (OIS):Hardware-based. Lub lens lossis sensor txav lub cev los tiv thaiv kev txav.
Electronic Image Stabilization (EIS):Software-based. Lub koob yees duab qoob loo cov duab thiab siv cov algorithms kom du suab.
Optical Image Stabilization (OIS)
OIS siv lub lens ntab ntab lossis txav sensor. Gyroscopes ntes cov lus tsa suab, thiab cov actuators me me hloov lub lens / sensor nyob rau sab nraud. Qhov zoo: tsis muaj kev daws teeb meem, zoo rau kev txav loj. Qhov tsis zoo: ntxiv qhov loj me, qhov hnyav, tus nqi - nyuaj raume koob yees duab moduletsim.
Electronic Image Stabilization (EIS)
EIS siv software. Lub koob yees duab captures ib qhov dav ntawm saib, ces cov qoob loo thiab hloov thav duab kom cov ntsiab lus nyob ruaj khov. Qhov zoo: tsis muaj qhov txav mus los, tus nqi qis dua, yooj yim rau kev siv. Qhov tsis zoo: qoob loo cov duab (txo FOV), tsis tshua muaj txiaj ntsig rau kev txav loj.
OIS vs EIS
| Feature | OIS | EIS |
|---|---|---|
| Tsiv qhov chaw | Yog lawm | Tsis muaj |
| Kev daws teeb meem poob | Tsis muaj | Cropping txo kev daws teeb meem |
| Kev ua tau zoo | Zoo rau kev txav loj | Zoo rau me me vibrations |
| Nqi | Siab dua | qis |
| Loj | Loj dua | Compact |
| Zoo tshaj rau | Handheld koob yees duab, high-end video | Drones, koob yees duab ua haujlwm, webcams |
Stabilization los ntawm Module Hom
Lub koob yees duab me me- Siv hauv kev kho mob endoscopes lossis drones. OIS tsis tshua muaj peev xwm (actuator loj dhau). Cia siab rau EIS lossis kev tswj hwm kev ruaj ntseg. Qee cov qauv tso tawm cov ntaub ntawv gyroscope rau kev ua haujlwm tom qab.
USB Lub Koob Yees Duab Module- Rau webcams lossis tshuaj xyuas. Feem ntau tsis muaj EIS built-in; host software (Zoom, Teams) ua kom ruaj khov. Kev lag luamusb koob yees duab modulentawm tripods tej zaum yuav tsis xav tau stabilization.
Lub Koob Yees Duab HD Module / HD Lub Koob Yees Duab Module- Rau cov koob yees duab ua haujlwm lossis cov khoom siv tes tuav. Feem ntau suav nrog EIS. Premium modules yuav suav nrog OIS. Drone-mountedHD Lub Koob Yees Duab ModuleFeem ntau siv EIS (OIS hnyav dhau).
CSI Lub Koob Yees Duab Module- MIPI CSI-2 rau Raspberry Pi, Jetson. Tsis tshua muaj xws li OIS (qhov loj / tus nqi). EIS siv nyob rau hauv software ntawm tus tswv tsev processor. Txheem rau robotics thiab drones.
CMOS Module Lub Koob Yees Duab-Txhua yamcmos module koob yees duabtuaj yeem txhawb EIS yog tias ISP / tus tswv tsev muaj peev xwm. OIS xav tau cov khoom siv tshwj xeeb. Feem ntau cov khoom lag luam yog mounted rau fixtures, yog li stabilization tsis xav tau.
Daim ntawv thov xav tau Stabilization
| Daim ntawv thov | Vim li cas Stabilization tseem ceeb |
|---|---|
| Handheld endoscope | Tus kws phais neeg tuav tes - EIS pab |
| Drone / aerial soj ntsuam | Lub cev muaj zog vibration - EIS qhov tseem ceeb |
| Action koob yees duab | Taug kev, khiav - OIS lossis EIS |
| Automotive (ADAS) | Txoj kev vibration - feem ntau mount-stabilized |
| Robotic caj npab soj ntsuam | Arm txav - EIS lossis software |
| Cov neeg siv khoom webcam | Cov neeg siv txav - EIS hauv software |
Sincere txoj kev
Ntawm Kev Ua Siab Zoo, peb pab cov neeg siv khoom xaiv OIS lossis EIS raws li qhov loj me, nqi, thiab kev ua haujlwm:
- Lub koob yees duab me me- Pom zoo EIS ntawm tus tswv tsev processor (Raspberry Pi, Jetson) kom txuag tau qhov chaw.
- Usb koob yees duab module- Muab cov qauv nrog cov ntaub ntawv gyroscope tso tawm rau tus tswv tsev-raws li EIS.
- Lub koob yees duab hd module / HD Lub Koob Yees Duab Module- tuaj yeem koom ua ke OIS rau cov khoom siv tes ua siab kawg uas qhov chaw tso cai.
