Dab tsi LED wavelengths xav tau rau LPR daim ntawv tso cai daim ntawv lees paub?

Hauv LPR (License Plate Recognition) systems, xaiv qhov tsim nyog LED wavelengths yog qhov tseem ceeb rau kev ua tiav qhov kev lees paub siab. Feem ntau, LED wavelengths hauv qab no yog siv:

LED Wavelengths siv hauv LPR

Dawb LEDs: Rau kev muab cov teeb pom kev zoo thiab ci ntsa iab, npog feem ntau ntawm cov teeb pom kev zoo (400-700nm).

Infrared LEDs: Pom tsis pom ntawm tib neeg lub qhov muag, muaj txiaj ntsig zoo rau qhov chaw tsis muaj teeb pom kev zoo thiab txhim kho kev xav ntawm daim ntawv tso cai (ib puag ncig 850nm).

Ultraviolet LEDs: Tso lub teeb ci ultraviolet los ua cov khoom siv fluorescent ntawm daim ntawv tso cai ci ci, txhim kho qhov sib txawv thiab pom tseeb (nyob ib puag ncig 365nm).

 

Cov yam ntxwv uas yuav tsum tau xav txog thaum xaiv cov teeb ci LED

Lub teeb siv zog: Kho raws li daim ntawv thov scenario kom paub meej cov duab.

Xim kub: cuam tshuam cov xim ntawm daim ntawv tso cai daim duab duab; xaiv raws li qhov xwm txheej tiag tiag.

Lifespan thiab Stability: Qhov tseem ceeb rau kev ua haujlwm ruaj khov mus ntev ntawm LPR system.

Los ntawm kev ua tib zoo xaiv qhov tsim nyog LED wavelengths thiab hom teeb pom kev zoo, LPR systems tuaj yeem txhim kho qhov tseeb thiab kev ntseeg siab ntawm daim ntawv tso cai daim ntawv lees paub.
