Visual sensing technology yog ib qho ntawm xya pawg loj ntawm kev paub txog technology. Visual sensors xa mus rau cov sensors uas xam cov yam ntxwv ntau (thaj chaw, qhov chaw ntawm lub ntiajteb txawj nqus, qhov ntev, txoj hauj lwm, thiab lwm yam) ntawm ib yam khoom los ntawm kev ua cov duab ntawm cov dluab ntes los ntawm lub koob yees duab, thiab tso zis cov ntaub ntawv thiab kev txiav txim. Cov teeb pom kev zoo yog cov ntaub ntawv ncaj qha rau tag nrho lub tshuab pom kev, feem ntau yog tsim los ntawm ib lossis ob daim duab sensors, qee zaum nrog lub teeb pom kev zoo thiab lwm yam khoom siv pabcuam. Lub luag haujlwm tseem ceeb ntawm lub zeem muag sensor yog kom tau txais cov duab qub txaus kom ua tiav los ntawm lub tshuab tsis pom kev.
Lub hauv paus ntsiab lus ua haujlwm ntawm qhov pom kev pom:
Lub zeem muag pib los ntawm ib txoj hauv kev kom tau txais cov ntaub ntawv ib puag ncig sab nraud hauv lub ntiaj teb lom neeg, thiab yog txoj hauv kev zoo tshaj plaws rau cov kab mob ntuj tsim kom tau txais cov ntaub ntawv. Nws yog ib qho ntawm cov khoom tseem ceeb ntawm kev txawj ntse lom neeg. "80 feem pua ntawm tib neeg cov ntaub ntawv tau txais los ntawm lub zeem muag. Raws li qhov kev tshoov siab no, cov kws tshawb fawb tau pib nruab "qhov muag" rau cov tshuab ua kom cov tshuab kom tau txais cov ntaub ntawv sab nraud los ntawm "saib" zoo li tib neeg, uas ua rau yug los ntawm kev qhuab qhia tshiab - computer vision . Los ntawm kev tshawb fawb txog kev pom kev lom neeg, tib neeg xyaum thiab tsim cov tshuab tsis pom kev, txawm hais tias muaj qhov sib txawv tseem ceeb ntawm tib neeg kev pom lub cev. ", Tab sis qhov no yog kev ua tiav ntawm kev siv tshuab sensor. Lub ntsiab lus ntawm kev siv lub ntsej muag sensor yog cov duab ua thev naus laus zis, uas ntes cov cim los ntawm qhov chaw ntawm cov khoom thiab kos duab rau kev nthuav qhia rau cov kws tshawb fawb.
Visual sensors muaj ntau txhiab pixels uas ntes lub teeb los ntawm tag nrho cov duab. Lub clarity thiab fineness ntawm cov duab feem ntau yog ntsuas nyob rau hauv cov nqe lus ntawm kev daws teeb meem, qhia nyob rau hauv cov nqe lus ntawm cov pixels. Tom qab ntes cov duab, lub qhov muag pom kev sib piv nws nrog cov duab siv khaws cia hauv nco rau kev tshuaj xyuas. Piv txwv li, yog tias lub teeb pom kev pom tau teeb tsa los txheeb xyuas cov khoom siv tshuab nrog yim lub bolts raug tso, lub sensor paub tias cov khoom uas tsuas yog xya lub bolts yuav tsum raug tso tseg, lossis cov khoom siv nrog cov bolts tsis zoo. Tsis tas li ntawd, tsis hais qhov twg lub tshuab tivthaiv nyob rau hauv qhov kev pom, thiab tsis hais seb cov khoom rotates li ntawm 360 degree ntau npaum li cas, cov teeb pom kev zoo tuaj yeem txiav txim siab. Qhov tshwm sim ntawm qhov pom kev siv tshuab daws qhov teeb meem ntawm lwm cov sensors tsis tuaj yeem ua haujlwm vim qhov chaw txwv qhov loj me lossis cov cuab yeej tshawb pom loj, uas tau txais tos dav los ntawm kev lag luam kev lag luam.
Kev pom kev siv thev naus laus zis suav nrog 3D pom kev siv thev naus laus zis, thiab 3D pom kev pom muaj ntau yam kev siv, xws li multimedia mobile xov tooj, network koob yees duab, digital koob yees duab, neeg hlau pom kev navigation, automotive kev nyab xeeb systems, biomedical pixel tsom xam, human-computer interfaces, virtual. Kev muaj tiag, kev soj ntsuam, kev sim kev lag luam, wireless chaw taws teeb sensing, microscopy technology, astronomical observation, autonomous ocean navigation, scientific instruments, thiab hais txog. Cov ntawv thov sib txawv no yog ua raws li 3D pom duab sensor thev naus laus zis. Tshwj xeeb, 3D duab thev naus laus zis muaj cov ntawv thov ceev hauv kev tswj hwm kev lag luam thiab kev tsav tsheb tsav tsheb.
Intelligent visual sensing technology kuj yog ib hom kev pom kev siv tshuab. Lub ntsej muag ntse ntse nyob rau hauv cov cuab yeej ntse ntse pom kev siv tshuab, tseem hu ua lub koob yees duab ntse, yog qhov ceev tshaj plaws tsim cov thev naus laus zis tshiab hauv kev ua haujlwm ntawm lub tshuab pom hauv xyoo tas los. Lub koob yees duab ntse yog lub tshuab me me tsis pom kev nrog lub luag haujlwm ntawm kev nrhiav cov duab, ua cov duab, thiab xa cov ntaub ntawv. Nws yog embedded computer vision system. Nws muab cov duab sensors, digital processors, kev sib txuas lus modules, thiab lwm yam khoom siv rau hauv ib lub koob yees duab. Vim qhov kev tsim qauv sib xyaw ua ke, qhov nyuaj ntawm qhov system tuaj yeem txo qis thiab kev ntseeg tau zoo dua. Nyob rau tib lub sijhawm, qhov system loj tau raug txo qis heev, nthuav dav hauv daim ntawv thov kev pom kev siv tshuab.
Qhov zoo ntawm cov cuab yeej ntse pom kev zoo xws li kev kawm yooj yim, siv, txij nkawm, thiab kev teeb tsa, nrog rau kev muaj peev xwm tsim kho qhov muag pom kev zoo thiab ua haujlwm zoo nyob rau lub sijhawm luv luv, tau ua rau kev txhim kho sai ntawm cov tshuab no. Cov duab nrhiav tau ntawm lub qhov muag pom kev pom feem ntau yog tsim los ntawm CCD / CMOS lub koob yees duab, lub tshuab kho qhov muag, lub teeb pom kev zoo, thiab daim npav yuav khoom. Nws hloov cov duab kho qhov muag rau hauv cov duab digital thiab xa mus rau cov duab ua haujlwm.
