Cov lus pom zoo xaiv rau 5-Megapixel USB Lub Koob Yees Duab Module
Hauv kev ua haujlwm xws li kev pom lub tshuab, kev saib xyuas kev ruaj ntseg, thiab cov duab kos duab, kev xaiv ntawm cov duab kos duab ncaj qha cuam tshuam rau kev ua tau zoo thiab kev ntseeg siab ntawm tag nrho cov kab ke. Raws li cov ntaub ntawv tshwj xeeb muaj, tsab xov xwm no muab cov kev tshuaj ntsuam xyuas ntawm lub koob yees duab module uas siv AR0331 sensor, muaj 5-megapixel tso zis, txhawb USB 2.0 interface thiab UVC plug-thiab-ua si raws tu qauv, thiab nthuav qhia cov lus pom zoo xaiv los qhia txog kev txiav txim siab kho vajtse rau cov haujlwm muaj feem xyuam.
1. Kev ntsuas kev ua tau zoo thiab kho qhov muag zoo
Lub module tau nruab nrog 1/3-inch AR0331 sensor ua ke nrog 2.2µm pixel loj, muab lub hauv paus ruaj khov rau kev ntsuas siab. Nws txhawb kev daws teeb meem txog 2048 × 1536 thiab ua tiav tus ncej tus nqi ntawm 30 fps raws li kev daws teeb meem feem ntau siv, ua kom tau raws li qhov yuav tsum tau muaj ntawm dynamic scenes qhov twg cov lus tsa suab yog qhov tseem ceeb. Qhov tseem ceeb, cov qauv qhia tau hais tias muaj kev ua tau zoo hauv kev tswj cov duab geometric distortion, nrog cov lus qhia meej qhia tias pincushion lossis chim distortion tsis tshaj 1%. Qhov kev ntsuas no tshwj xeeb yog qhov tseem ceeb rau kev pom kev pom tseeb xws li kev ntsuas qhov ntev thiab qhov chaw tso khoom. Tsis tas li ntawd, qhov yuam kev ntawm kev tsim cov xim yog txwv tsis pub dhau 20%, thiab kho qhov tsis zoo rau qhov ci, qhov sib piv, qhov sib luag, thiab qhov sib npaug dawb tso cai rau cov qauv kom muaj xim zoo sib xws nyob rau hauv cov teeb pom kev sib txawv.
2. Interface thiab Protocol Compatibility
Lub module txais yuav USB 2.0 interface thiab ua raws li UVC (USB Video Class) plug{1}}thiab-play protocol. Qhov kev tsim no ua rau muaj tseeb ntsaws- thiab- ua si ua haujlwm thoob plaws Windows XP los ntawm Windows 10 systems, txo qhov nyuaj ntawm kev sib koom ua ke thiab kev saib xyuas. Nyob rau hauv cov nqe lus ntawm cov zis tawm tswv yim, nws txhawb peb hom encoding: MJPG, YUY2, thiab H.264, muab cov neeg siv yooj yim hauv cov duab ntes thiab compression thoob plaws platforms nrog sib txawv bandwidths thiab muaj peev xwm ua. Tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas muaj siab tiag tiag- lub sijhawm yuav tsum tau ua, suav nrog H.264 pab tswj cov duab zoo thaum txo qis kev sib kis.
3. Environmental Adaptability thiab Reliability
Nrog rau kev khiav hauj lwm kub ntawm -20℃mus rau 70℃thiab ib tug ruaj khov kev khiav hauj lwm ntau yam ntawm 0℃mus rau 50 degree, lub module qhia ib tug℃ntawm dav -kub adaptability, ua rau nws haum rau xa mus nyob rau hauv ib puag ncig nrog tseem ceeb sab hauv tsev- sab nraum zoov kub variations. Cov kev ntsuam xyuas kev ntseeg tau tau teev tseg hauv cov lus qhia tshwj xeeb npog qhov kub thiab tsis kub cia thiab ua haujlwm, thermal shock, dawb- caij nplooj zeeg, kev co, thiab electrostatic paug. Cov xwm txheej xeem thiab cov qauv kev lees paub tau txhais tau meej meej -piv txwv li, qis- qhov ntsuas kub ua haujlwm tau ua ntawm -30℃rau 96 teev, thiab kev ntsuas poob yog ua los ntawm qhov siab ntawm 150 cm rau 10 repetitions. Cov txiaj ntsig kev xeem no qhia tau hais tias cov qauv tau tsim thiab tsim los tiv thaiv qee qhov ntawm cov neeg kho tshuab thiab ib puag ncig kev ntxhov siab, ua rau nws tsim nyog rau cov chaw lag luam, kev ruaj ntseg sab nraum zoov, thiab lwm yam xwm txheej uas yuav tsum muaj kev ntseeg siab.
4. Mechanical Design and Manufacturing Details
Lub module nta ib daim ntawv cog lus ntsuas 38 hli × 38 hli, yooj yim rau kev sib koom ua ke. Cov txheej txheem tsim khoom siv SMT (Surface Mount Technology) thiab ua raws li RoHS cov qauv, ua kom muaj kev ua raws li ib puag ncig thiab ntev -lub sij hawm sib koom ua ke kev ntseeg tau los ntawm cov khoom siv. Cov ntaub ntawv qhia tshwj xeeb suav nrog cov kev xav tau meej meej rau kev kuaj xyuas lub lens kom huv, sealing daim ntawv thov, thiab pom qhov tsis xws luag -piv txwv li, lub lens yuav tsum tsis pom muaj khawb los yog kis kab mob nyob rau hauv lub teeb pom kev zoo, thiab lub sealant yuav tsum tau muab sib npaug zos rau yam tsis muaj overflow. Cov ntsiab lus zoo li no feem ntau cuam tshuam txog qib kev tswj hwm ntawm cov txheej txheem tsim khoom thiab ua cov ntaub ntawv tseem ceeb rau kev ntsuas cov khoom sib xws thiab ua haujlwm ntev thaum xaiv.
Summary of Selection Recommendations
Thaum xav txog kev txais yuav hom koob yees duab module, nws raug nquahu kom ua qhov kev ntsuam xyuas dav dav raws li qhov loj me hauv qab no:
