Dab tsi yog External Trigger Camera Module?
Lub Sab Nraud Trigger Lub Koob Yees Duab Module yog ib qho khoom siv tshwj xeeb uas tsim los pib cov duab lossis yees duab ntes tsuas yog hauv cov lus teb rau cov teeb liab sab nraud, ua kom muaj tseeb synchronization nrog cov txheej txheem sab nraud, cov xwm txheej, lossis cov khoom siv. Nws tus nqi tseem ceeb nyob rau hauv kev sib txuas cov duab ua haujlwm nrog cov xwm txheej tiag tiag hauv ntiaj teb, kom ntseeg tau tias lub sijhawm ntes tau sib haum nrog cov xwm txheej tshwj xeeb.
Tshaj li cov ntsiab lus tseem ceeb, nws muaj peb yam tseem ceeb uas paub qhov txawv ntawm cov kev daws teeb meem zoo tib yam:
- Lub tswv yim tseem ceeb: Nws decouples qhov kev txiav txim siab ntawm "thaum twg" los ntes cov duab los ntawm lub koob yees duab nws tus kheej, muab kev tswj hwm rau qhov xwm txheej sab nraud. Lub koob yees duab tseem nyob rau hauv lub xeev standby, ua raws li ib tug passive execution unit kom txog thaum nws tau txais cov lus txib.
- Cov Ntsiab Lus Tseem Ceeb: Lub ntsiab lus ntawm cov qauv no yog nws qhov kev tawm tswv yim tus pin (GPIO), uas yog tsim los kom tau txais cov cim taw qhia sab nraud.
- Kev Ua Haujlwm: Thaum muaj qhov teeb meem tshwm sim ua ntej tau ntsib (piv txwv li, qhov hluav taws xob nce siab), lub koob yees duab tam sim ntawd ua tiav qhov raug ntes rau ib tus ncej lossis ib ntu ua ntej.
Hauv qhov tseem ceeb, nws yog lub zeem muag sensor tsim los rau kev sib koom ua ke thiab kev tshwm sim - tau tsav cov duab tau.
Qhov txawv ntawm Sab Nraud Trigger Camera Module thiab Ordinary Camera Module?
Qhov tseem ceeb sib txawv ntawm ob qhov lus dag nyob rau hauv "txawm hais tias lub sijhawm ntes yog tswj los ntawm cov teeb liab sab nraud lossis sab hauv logic." Hauv qab no yog cov ncauj lus kom ntxaws sib piv siv qhov loj me:
|
Sib piv Dimension |
Sab nrauv Trigger Lub Koob Yees Duab Module |
Ordinary Camera Module |
|
Trigger Source & Capture Logic |
Cia siab rau cov teeb liab sab nraud (xws li, sensor pulses, controller commands) pib ntes; tsis muaj autonomous capture los ntawm lub neej ntawd. |
Cia siab rau cov logic sab hauv (piv txwv li, cov neeg siv phau ntawv ua haujlwm, app commands, timers, los yog nruam shooting settings) pib capture. |
|
Synchronization Muaj peev xwm |
Siab: Txhawb ntau- cov khoom synchronization (xws li, ntau lub koob yees duab, sensors) ntawm kev sib koom ua ke sab nraud; lub sij hawm yuam kev<1ms. |
Tsawg: Nyuaj rau synchronize nrog cov tshuab sab nraud; Lub sijhawm ntes yog ywj siab ntawm cov xwm txheej sab nraud (piv txwv li, lub koob yees duab hauv xov tooj tsis tuaj yeem sync nrog lub conveyor siv sensor). |
|
Latency ntawm Capture Initiation |
Tsawg (khoom siv kho vajtse: ~ 0.1–1ms; software trigger: ~ 10–50ms) kom tau raws li siab -kev ceev xwm txheej xav tau. |
Siab (feem ntau ~ 100–500ms) vim kev ua haujlwm sab hauv (piv txwv li, app teb, nws pib- tsom xam kho) ua ntej ntes. |
|
Kev siv fais fab |
qis dua: Tseem nyob hauv "tsis muaj zog" thaum tsis muaj qhov tshwm sim (tsuas yog cov kab hluav taws xob yooj yim nkaus xwb); siv zog tsuas yog thaum ntes. |
Siab dua: Ua kom puv - lub zog ua haujlwm txawm tias tsis ntes (xws li, saib ua ntej tas mus li, nws pib-sensor saib xyuas) los txhawb kev ntes tus kheej. |
|
Core Application Hom phiaj |
"Event-driven imaging": capture dluab/videos raws nraim thaum muaj xwm txheej tshwm sim (xws li, kuaj xyuas cov khoom tsis raug, kaw qhov siab -kev sib tsoo ceev). |
"Scenario-kev ywj pheej imaging": Kev ntes raws li tus neeg siv xav tau lossis ua ntej- teeb tsa cov cai (piv txwv li, thaij duab scenery, kaw cov yeeb yaj kiab txhua hnub). |
