Software thiab kho vajtse rau advanced kev ruaj ntseg tshuab yog muaj peev xwm mus daws tau cov teeb meem ntawm tej complexity ntawm tag nrho cov hom ntawm industrial, kev sib raug zoo thiab domestic hom phiaj. Cov cuab yeej tseem ceeb ntawm kev ruaj ntseg tshuab yog video surveillance systems, thiab cov kev cai rau kev ua haujlwm ntawm lub tshooj yog nce zuj zus ntxiv.

Integrated kev ruaj ntseg tshuab

Tib platform kev ruaj ntseg system muaj xws li modules hluav taws kev tiv thaiv cov khoom, kev nkag tswj, CCTV, los yog kaw Circuit Court TV (cot). Cov dej num ntawm qhov kawg kom txog thaum nyuam qhuav raug txwv rau kev saib xyuas thiab yees duab ntawm qhov teeb meem ntawm lub vev xaib thiab nyob ib sab ntawm thaj chaw, archiving thiab cia cov ntaub ntawv. Cov kev yees duab classical muaj ntau qhov teeb meem tseem ceeb:

• Qhov zoo tshaj plaws ntawm tib neeg. Ua haujlwm ntawm lub lag luam thaum tus tshaj tawm tawm xov xwm ntau heev.
• Impossibility ntawm kev phais kev phais, tsis tuaj yeem tsom xam.
• Lub sijhawm muaj nuj nqis rau kev nrhiav thiab cim qhov kev tshwm sim.

Txoj kev loj hlob ntawm digital technologies coj mus rau creation ntawm "ntse" tshuab kaw lus.

Muaj zog hauv kev txawj ntse

Lub hauv paus ntsiab lus ntawm lub ntsej muag video keb soj ntsuam yog video analytics - ib lub tshuab raws li kev siv thiab kev siv algorithms rau cov duab paub thiab cov duab ua, sau cov ntaub ntawv sau los ntawm kev tshawb fawb video. Cov khoom siv yam tsis muaj kev pabcuam pejxeem tuaj yeem ntes thiab taug qab nyob rau ntawm lub sijhawm ntawm lub sijhawm (lub tsheb, pab pawg neeg), qhov teeb meem uas muaj feem cuam tshuam (pa taws, hluav taws, tsis cuam tshuam kev cuam tshuam nrog kev lag luam ntawm cov koob yees duab video), cov xwm txheej hauv lub programmed thiab lub sijhawm teem ceeb toom. Vim qhov kev lim dej ntawm cov ntaub ntawv video tsis muaj paj laum, cov thauj ntawm kev sib txuas lus raws thiab cov archive database yog ho txo.

Cov ntsiab lus nrov tshaj plaws ntawm video analytics yog lub ntsej muag ntawm lub ntsej muag paub. Nyob ntawm cov dej num tau ua thiab cov hauj lwm uas tau muab rau, qee qhov yuav tsum tau muaj rau cov khoom siv.

Firmware

Rau kev ua haujlwm ntawm cov txheej txheem, ntau hom IP koob yees duab nrog cov yam ntxwv ua haujlwm sib txawv. Tshawb nrhiav ntawm qhov khoom nyob rau hauv cov tswj kev kawm yog kho los ntawm panoramic view cameras nrog ib lub rooj ntawm 1 Mp thiab ib tug focal ntev ntawm 1 mm thiab yog coj los ntawm kev thaij cuab yeej. Cov no yog cov koob yees duab ntau dua (ntawm 2Mp, ntawm 2 hli), uas tsim kev paub txog cov tswv yim yooj yim (3-4 tsis muaj). Txheeb xyuas cov khoom siv cov koob yees duab nrog cov duab zoo, zoo rau daim ntawv thov ntawm cov txheej txheem algorithms (ntawm 5 Mp, 8-12 mm). Qhov nrov tshaj plaws software rau ntsej muag lub suab "Face Intellect" (tsim tawm - lub tuam txhab Tsev Tswj), Lub ntsej muag tus thawj coj (lub tuam txhab "Synesis") thiab VOCORD FaceControl (VOCORD) qhia txog:

• Kev muaj peev xwm ntau dua ntawm qhov khoom (txog li 99%).
• Kev them nyiaj yug rau ntau hom kev sib hloov cov koob yees duab.
• Tseem muaj kev sib cais tib neeg txawm nyob hauv ib qho kev sib txeeb ntiv taw.
• Lub vam meej ntawm kev npaj cov ntaub ntawv tshawb xyuas.

Cov qauv ntawm kev paub txog tus qauv

Cov kev paub txog biometric biometric yog los ntawm kev txheeb xyuas cov kev sib txuas ntawm tus qauv ntawm tus neeg tau nyeem rau ib qho qauv tshwj xeeb. Kev xaav yuav siv qhov chaw nyob rau ntawm lub sijhawm. IP lub koob yees duab broadcasts video kwj mus rau lub davhlau ya nyob twg, thiab lub ntsej muag kev paub lub ntsej muag pom cov ntawv xov ntawm cov duab rau cov duab khaws cia hauv database. Muaj ob txoj kev loj. Thawj yog raws li cov ntsiab lus zoo li qub: cov ntsiab lus ntawm kev ua biometric tsis tsim ib qho hluav taws xob hauv cov qauv ntawm ib tug xov tooj tshwj xeeb uas muaj feem xyuam rau ib tus neeg. Qhov thib ob hom ua qauv rau "tib neeg" thiab nws yog yus tus kheej txoj kev kawm thiab kev coj ua. Kev qhia ntawm ib tug neeg raws li daim duab yees duab yuav siv rau qhov kev hloov hauv lub hnub nyoog thiab lwm yam (muaj ib lub siab, ib hwj txwv los yog khauj tsiav, tsom iav). Cov cuab yeej no tso cai rau koj mus ua hauj lwm txawm tias cov duab qub thiab, yog tias tsim nyog, nrog X-rays.

Ntsej muag Nrhiav Algorithm

Qhov feem ntau ntawm txoj kev kuaj pom ntsej muag yog siv Haar cascades (poob lawm ntawm qhov ncauj qhov ntswg). Lub npog ntsej muag yog ib qhov rectangular window nrog sib txawv ua ke ntawm cov xim dub thiab dub.

Lub tswv yim ntawm qhov kev zov me nyuam yog raws li nram no: cov duab thaij duab yog npog nrog lub npog qhov ncauj qhov ntswg, thiab los ntawm cov txiaj ntsig ntawm qhov kev sib haum xeeb (suav cov pixels ntes hauv cov xim dub thiab dub) qhov sib txawv sib piv, piv rau ib qho chaw pib tus nqi.

Los txhim kho txoj hauj lwm ntawm chav ua haujlwm, qhov zoo (thav ntawv, qhov twg neeg muaj ntsej muag) thiab qhov tsis zoo (tsis muaj) cov qauv kev kawm raug tsim. Nyob rau hauv rooj plaub thawj zaug, qhov tshwm sim ntawm kev pom zoo yog siab tshaj tus nqi pib, nyob rau hauv rooj plaub thib ob nws qis dua. Lub ntes ntawm cov neeg uas muaj qhov yuam cai muaj kev txiav txim siab pom cov nyiaj sib tw ntawm tag nrho cov cascades thiab, yog tias qhov pib tshaj qhov teeb meem, qhia cov neeg nyob hauv kab ntawv.

Vev thaus liv yees duab

Tom qab nrhiav tau thiab thaj chaw, lub teeb ci thiab qhov sib lawv liag ntawm daim duab tshwm sim nyob rau hauv theem ua ntej. Ntxiv ua - xam cov nta thiab kev qhia - muaj peev xwm nqa tawm los ntawm ntau txoj kev.

Thaum luam ib lub ntsej muag tag nrho hauv ib chav uas muaj teeb pom kev zoo, cov txiaj ntsim tau zoo yog qhia los ntawm algorithms uas ua haujlwm nrog 2D dluab. Ntsuam xyuas cov ntsiab lus thiab kev ncua ntawm lawv, lub ntsej muag ntawm lub ntsej muag ntsej muag pom tseeb qhov tseeb ntawm kev qhia los ntawm cov coefficients ntawm qhov txawv ntawm qhov "live" snapshot thiab tus qauv sau npe.

Cov duab thaij duab 3-dimensional tiv taus cov kev hloov hauv lub teeb pom kev zoo, qhov kev pom zoo ntawm lub kaum sab xis yog nce mus txog 45 degree. Ntawm no, tsis yog cov ntsiab lus thiab cov kab yog cov kev soj ntsuam, tab sis kuj yog cov khoom ntawm qhov chaw (curvature, profile), lub metric ntawm ncua ntawm lawv. Rau kev khiav lag luam ntawm cov kev pom zoo li no, qhov siab tshaj plaws ntawm kev teev cia cov video nrog rau cov zaus txog li 200 thav ob ntawm yuav tsum tau ua. Lub hauv paus ntawm lub kaw lus muaj cov koob yees duab tso suab nrog ib lub duab ntawm 5 megapixels, siab kho qhov daws teeb meem thiab kev ua yuam kev tsawg teev synchronization. Tsis tas li ntawd, lawv txuas nrog lub sij hawm tshwj xeeb sij hawm xa mus rau cov sync pulses.

Lub xeev ntawm kev ua lag luam niaj hnub

Thawj lub nruab ntawm kev tswj hwm biometric, vim tias lawv cov nqi siab, tau tsim rau cov tub rog hauv xeev xwb thiab tsuas yog nyob rau nruab nrab thaum xyoo 1990 uas lawv muaj rau cov koom haum lag luam. Txoj kev loj hlob sai ntawm technology thiab microprocessor technology tau tso cai rau kom muaj tseeb ntawm lub tshuab thiab nthuav cov uas muaj ntawm lawv daim ntawv thov. Nyob rau hauv kev ua lag luam ntawm peb lub teb chaws txoj hauj lwm muaj rau American thiab West European kev ruaj ntseg system tuam ntxhab. Tus thawj coj ntawm kev muag khoom yog cov cuab yeej ntawm cov tuam txhab ZN Vision Technology thiab Visionics. Cov lus cog tseg loj tshaj plaws ntawm Lavxias teb sab yog cov kev tshawb fawb thiab cov khoom siv ntawm Vocord, NTechLab, Soling, VizhnLabs thiab MDG pawg, uas, nrog rau lwm yam, kuj koom nrog txawv teb chaws complexes rau Lavxias teb sab.

Lub Computer Lub Cev Ntsej Muag

Lub teb daim ntawv tshaj tawm txog kev tiv thaiv tsis tseem ceeb yog kev sib ntaus tawm tsam kev ua phem thiab kev ua phem. Daim duab ntawm lub txim txhaum lub ntsej muag yog muab cia rau hauv cov ntaub ntawv. Nyob rau hauv cov chaw uas muaj kev sib ntau ntawm tib neeg (tshav dav hlau, tsheb nqaj hlau, chaw kav khw, chaw sib tw ua si), ib qho dej ntawm cov neeg raug kaw cia rau cov neeg uas xav tau kev pab.

Tus kheej tom ntej yog kev tswj cov kev tswj: tus qauv ntawm daim duab duab ntawm daim pib hluav taws xob yog muab piv nrog cov qauv tau los ntawm cov ntaub ntawv ua los ntawm cov koob yees duab yees duab. Cov txheej txheem yuav siv qhov chaw instantly, tsis tau ntxiv cov yeeb yam ntxiv (as opposed to luam cov retina ntawm lub qhov muag los yog dactyloscopy).

Lwm txoj kev lag luam loj sai yog kev lag luam. Sib tham sib billboard yuav luam theej duab ib tug neeg lub ntsej muag, thiab txiav txim seb nws pw ua ke thiab uas muaj hnub nyoog, visualizes tsuas yog tus tawm hais tias yuav tsum muaj feem nthuav rau tus neeg.

Tshaj tawm thiab kev npaj kev txhim kho

Lub systems ntawm paub ntawm cov neeg nyob rau hauv lub banking sector yog heev nyob rau hauv kev thov. Vim tias dhau xyoo, tom qab lub installation ntawm 50,000 ntse yees duab yees hauv lawv qhov chaw ua hauj lwm, lub Post Bank Bank tau tswj kom muaj nyiaj ntau lab ntawm cov nyiaj los ntawm kev tiv thaiv kev dag hauv cov credit thiab them nyiaj. Kws txawj ntse hais tias los ntawm 2021 yuav tsum tsim kom muaj kev sib koom tes tsim kho cov cuab yeej hluav taws xob thiab cov kev khiav haujlwm hauv cov ATM yuav ua tau tom qab lub cim qhia tus neeg lub ntsej muag.

Nyob rau hauv kaum xyoo tom ntej high technologies yuav cia qhib lub network ntawm lub khw uas muaj kev pabcuam rau tus kheej: tus neeg yuav khoom dhau los ntawm lub khw muag khoom, xaiv qhov khoom lawv nyiam thiab nplooj. Lub system ntawm kev paub txog cov duab thiab cov duab yuav txiav txim seb tus neeg yuav tus neeg yuav khoom, yuav yuav thiab yuav cia nws tus account kom tsim nyog.

Ua hauj lwm yog tab tom tsim los tsim cov txheej txheem rau kev pom lub xeev kev xav. Kev ntsuam xyuas ntawm tib neeg tus cwj pwm txawv yuav tsum muaj nyob rau hauv kev sib txuas lus hauv ntau hom xov xwm: animation, cinematography, kev lag luam ntawm creation ntawm lub computer ua si.
