Isihloko sokulandelela umhlanganyeli okhulumayo engqungqutheleni ngevidiyo siye sathuthuka kule minyaka embalwa edlule. Ubuchwepheshe buye benza kwaba nokwenzeka ukusebenzisa ama-algorithms ayinkimbinkimbi okucubungula ulwazi lomsindo/lwevidiyo ngesikhathi sangempela, okwenze i-Polycom, cishe eminyakeni eyi-10 edlule, yethula isisombululo sokuqala esivamile emhlabeni esinokulandelela isipikha esihlakaniphile. Iminyaka eminingana bakwazi ukuhlala bebodwa abanikazi besixazululo esinjalo, kodwa uCisco akazange alinde isikhathi eside futhi alethe emakethe inguqulo yabo yohlelo oluhlakaniphile lwamakhamera amabili, okwakungumncintiswano ofanelekile wesixazululo esivela kuPolycom. Iminyaka eminingi, le ngxenye ye-videoconferencing ibikhawulelwe ngamakhono abantu abambalwa okuphathelene imikhiqizo, kodwa lesi sihloko sinikezelwe kweyokuqala jikelele isixazululo sokuqondiswa kwekhamera ngezwi, elihambisana nakho kokubili ihadiwe kanye nengqalasizinda yesofthiwe yenkomfa ngevidiyo.
Ngaphambi kokudlulela ekuchazeni izixazululo kanye namakhono okukhombisa, ngifuna ukuqaphela umcimbi obalulekile:
Ngizizwa ngihloniphekile ukwethula emphakathini wakwaHabra , ezinikezelwe kuzixazululo ze-videoconferencing (VCC). Manje, ngenxa yemizamo ehlanganyelwe (eyami kanye ne-UFO), inekhaya layo ku-Habré, futhi ngimema wonke umuntu obambe iqhaza kulesi sihloko esibanzi nesamanje ukuthi abhalisele .
Izimo ezimbili zokukhomba ikhamera esipikheni
Okwamanje, abahlanganisi bezixazululo zenkomfa ngevidiyo bazikhethela bona izindlela ezimbili ezihlukene zokwenza umsebenzi wokukhomba umethuli:
- Okuzenzakalelayo - Intelligent
- I-Semi-automatic - iyahleleka
Inketho yokuqala yizixazululo ezivela kuCisco, Polycom nabanye abakhiqizi; sizozicabangela ngezansi. Lapha sibhekene nokuzenzakalela okuphelele kokukhomba umhlanganyeli okhulumayo engqungqutheleni yevidiyo. Ama-algorithms ahlukile okucubungula amasignali omsindo/ividiyo avumela ikhamera ukuthi ikhethe indawo efunekayo ngokuzimela.
Inketho yesibili i-automation systems esekelwe kuzilawuli ezihlukahlukene zangaphandle; ngeke sizicabangele ngokuningiliziwe, ngoba I-athikili igxile ekulandeleleni izipikha ngokuzenzakalelayo.
Kunabasekeli abambalwa besimo sesibili sokuqalisa ukukhomba ngekhamera, futhi kunezizathu zalokhu. Abahlanganisi abanolwazi bayaqonda ukuthi izixazululo ezihlakaniphile ezivela ku-Polycom ne-Cisco zidinga izimo zokusebenza ezikahle ukuze okuzenzakalelayo kusebenze kahle. Kodwa akwenzeki ngaso sonke isikhathi ukunikeza izimo ezinjalo, ngakho-ke ukusebenza kwesistimu ngezinye izikhathi kuqinisekiswa yisixazululo esilandelayo senkinga yokukhomba ikhamera:
1. Konke ukulungiselelwa okudingekayo (izikhundla zedivayisi ye-PTZ kanye ne-optical zoom factor) zifakwa ngesandla kusengaphambili kumemori yekhamera (noma ngezinye izikhathi kusilawuli). Njengomthetho, lolu uhlelo olujwayelekile lwegumbi lomhlangano, kanye nokubuka komhlanganyeli ngamunye wenkomfa kumodi yokuma ngobude.
2. Okulandelayo, abaqalisi bokubiza ukusetha ngaphambilini kufakwa ezindaweni ezishiwo - lezi kungaba ama-microphone consoles noma izinkinobho zomsakazo, ngokuvamile, noma iyiphi idivayisi enganikeza isilawuli isignali esiyiqondayo.
3. Isilawuli sokulawula sihlelwe ngendlela yokuthi umqalisi ngamunye ube nokusetha kwawo kusengaphambili. Uhlelo olujwayelekile lwegumbi - bonke abaqalisi bavaliwe.
Ngenxa yalokho, lapho usebenzisa i-congress system, isibonelo, kanye nesilawuli esilawulayo, isikhulumi, ngaphambi kokuqala inkulumo yaso, sivula ikhonsoli ye-microphone yomuntu siqu. Isistimu yokulawula icubungula ngokushesha indawo yekhamera elondoloziwe.
Lesi simo sisebenza ngokungenasici - isistimu ayidingi ukwenza unxantathu wezwi nokuhlaziya amavidiyo. Ngicindezele inkinobho futhi ukusetha ngaphambilini kwasebenza, akukho ukubambezeleka noma imibono engamanga.
Amasistimu okulawula kanye ne-automation asetshenziswa emakamelweni amakhulu, ayinkimbinkimbi, lapho ngezinye izikhathi engekho eyodwa, kodwa amakhamera wevidiyo amaningana afakiwe. Yebo, emakamelweni okuhlangana amancane naphakathi nendawo, amasistimu azenzakalelayo afaneleka impela (uma unesabelomali).
Ake siqale ngabasunguli bobaba.
Umqondisi we-Polycom EagleEye
Lesi sixazululo sake sadala umuzwa emkhakheni wenkomfa ngevidiyo. I-Polycom EagleEye Director yaba yisixazululo sokuqala emkhakheni wokuqondisa amakhamera ohlakaniphile. Isixazululo siqukethe iyunithi yesisekelo ye-EagleEye Director namakhamera amabili. Isici salokho kuqaliswa kokuqala ukuthi ikhamera eyodwa yabelwe kuphela ukubuka eduze kwesikhulumi, futhi okwesibili - ohlelweni olujwayelekile lwegumbi lomhlangano. Ngesikhathi esifanayo, ikhamera yohlelo olujwayelekile ingabekwa ngokuhlukana ngokuphelele nesisekelo kwenye indawo egumbini lomhlangano - ayibandakanyeki ngokuqondile enqubweni yokuqondisa ezenzakalelayo.
Uhlelo lusebenza kanje:
- Ikhamera yegumbi elijwayelekile iyasebenza - wonke umuntu uthule
- Isipikha siqala ukukhuluma - i-microphone array iphakamisa izwi, ikhamera iya emsindweni isebenzisa ubuchwepheshe obunelungelo lobunikazi obuhlanganisa unxantathu wezwi. Ikhamera evamile isasebenza
- Ikhamera eyinhloko isanda kuqala ukubheka umthombo womsindo, yenza izibalo zevidiyo. Isistimu ihlonza isipikha ngoxhumano lwe-eye-nose-mouth, ifreyima isithombe sesipikha futhi ibonise ukusakaza okuvela kukhamera enkulu.
- Isipikha siyashintsha. Uhlu lwamakrofoni luyaqonda ukuthi izwi livela kwenye indawo. Uhlelo olujwayelekile luyavulwa futhi.
- Bese kuba yindilinga, kusukela ephuzwini lesi-2
- Uma isipikha esisha sikuhlaka lwangaphambilini, isistimu yenza ushintsho lwendawo “eshisayo” ngaphandle kokushintsha ukugeleza okusebenzayo kube ishothi evamile.
Okubi, ngokubona kwami, ukuba khona kwekhamera eyodwa kuphela eyinhloko. Lokhu kubangela ukubambezeleka okukhulu lapho kushintsha izipikha. Futhi ngaso sonke isikhathi ngesikhathi sokukhomba, uhlelo luvula uhlelo olujwayelekile lwegumbi - phakathi nengxoxo ejabulisayo, lokhu kucwayiza kuqala ukucasula.
Umqondisi we-Polycom EagleEye II
Lena inguqulo yesibili yesixazululo esivela ku-Polycom, ekhishwe kamuva nje. Umgomo wokusebenza uye waba nezinguquko futhi usufana nesixazululo esivela kwaCisco. Manje womabili amakhamera e-PTZ yiwo ayinhloko futhi asebenza ngokushintsha iziteshi ngaphandle komthungo esuka komunye umethuli aye komunye. Isakhiwo esijwayelekile segumbi lomhlangano manje sithwetshulwa ikhamera ehlukile ehlanganiswe emzimbeni weyunithi yesisekelo ye-EagleEye Director II. Ngesizathu esithile, ukusakaza okuvela kule khamera ye-engeli ebanzi kuboniswa efasiteleni elingeziwe ekhoneni lesikrini, elithatha u-1/9 wokusakaza okuyinhloko. Umgomo wokuma uyafana - unxantathu wezwi nokuhlaziywa kokusakaza kwevidiyo. Futhi amabhodlela ayafana: uma uhlelo lungawuboni umlomo okhulumayo, ikhamera ngeke ihlose. Futhi lesi simo singenzeka kaningi - isikhulumi sifulathele, isikhulumi siphendukele eceleni, isikhulumi siyi-ventriloquist, isikhulumi sivale umlomo waso ngesandla noma idokhumenti.
Womabili amavidiyo okukhangisa ashuthwe ngendlela efanele - abantu abangu-2 bakhuluma ngokushintshana, futhi bavula imilomo yabo njengokungathi ngesikhathi sokubonana nomelaphi wenkulumo. Kodwa ngisho nasezimweni ezinjalo ezicwengisisiwe kukhona ukubambezeleka okukhulu kakhulu. Kepha uhlaka alunasici - i-portrait shot enethezekile.
I-Cisco TelePresence SpeakerTrack 60
Ukuchaza lesi sixazululo, ngizosebenzisa umbhalo ovela encwajaneni esemthethweni.
I-SpeakerTrack 60 ithatha indlela eyingqayizivele yamakhamera amabili ukushintsha ngokushesha phakathi kwabahlanganyeli. Enye ikhamera ithola ngokushesha ukusondelana komethuli osebenzayo, kuyilapho enye icinga futhi ibonise umethuli olandelayo. Isici se-MultiSpeaker sivimbela ukushintsha okungadingekile uma isipikha esilandelayo sesivele sikhona kuhlaka lwamanje.
Ngeshwa, angizange ngibe nethuba lokuzivivinya mina i-SpeakerTrack 60. Ngakho-ke, iziphetho kufanele zifinyelelwe ngokusekelwe embonweni "ovela ensimini" futhi ngokusekelwe emiphumeleni yokuhlaziywa kwevidiyo yomboniso engezansi. Ngibale ukubambezeleka okukhulu cishe kwemizuzwana eyi-8 lapho ngikhomba umethuli omusha. Ukulibaziseka okumaphakathi bekungamasekhondi angu-2-3, uma kubhekwa ividiyo.
I-HUAWEI Intelligent Tracking Video Camera VPT300
Ngithole lesi sixazululo esivela kuHuawei ngephutha. Isistimu ibiza cishe u-$9K. Isebenza kuphela ngamatheminali eHuawei. Onjiniyela bangeze “iqhinga” labo - ukwakheka kwevidiyo kusuka kuzipikha ezimbili esikrinini esisodwa uma kungekho omunye egumbini. Mayelana nezici nokusebenza okumenyezelwe, lena inguqulo ethakazelisa kakhulu yesistimu yokuqondisa ezenzakalelayo. Kodwa, ngeshwa, angitholanga nhlobo impahla yedemo. Okuwukuphela kwevidiyo evele kulesi sihloko kube ukubuyekezwa kwevidiyo ehleliwe yesixazululo, ngaphandle komsindo wangempela, osethelwe emculweni. Ngakho, kwakungenakwenzeka ukuhlola izinga lesistimu. Ngenxa yalesi sizathu, ngeke ngicabangele le nketho.
Ngiyabona ukuthi uHuawei unebhulogi esebenzayo ku-Habré - mhlawumbe ozakwabo bazokwazi ukushicilela ulwazi oluwusizo ngalo mkhiqizo.
Isixazululo esisha - jikelele
- i-monoblock, ehlanganisa amakhamera amabili e-PTZ okulandelela izikhulumi, amakhamera amabili akhelwe ngaphakathi okuhlaziya ukwakheka okujwayelekile kwegumbi, kanye ne-microphone array eyakhelwe esisekelweni secala - njengoba ubona, awekho ama-bulky futhi izakhiwo ezintekenteke njengalezo zabamelene nazo.
Ngaphambi kokuthi ngiqale ukuchaza umkhiqizo omusha, ngizohlanganisa izici nezici zezixazululo ezivela kwaCisco nasePolycom ukuze ngiqhathanise. ngokunikezwa okukhona.

- Ukuxhumana okuguquguqukayo — nge-HDMI, isistimu ihlangana nazo zombili izinhlelo zekhompiyutha zekhompiyutha nesoftware yevidiyo
- Izindleko eziphansi - Ngokusebenza okufanayo, i-A12VT ithengeka kaningi kusabelomali kuneziphakamiso ezichazwe ngenhla.
Ukukhombisa ukuthi isistimu isebenza kanjani, siqophe ukubuyekezwa kwevidiyo. Umsebenzi wawungewona ukukhangisa kangako kunokusebenza. Ngakho-ke, ividiyo ayinazo izindlela zevidiyo yokuphromotha yePolycom. Indawo ekhethelwe ukwethulwa bekungelona ihhovisi elimele abantu, kodwa bekuyigumbi lomhlangano elabhorethri likazakwethu, inkampani ye-IPMatika.
Umgomo wami wawungekona ukufihla amaphutha esistimu, kodwa, ngokuphambene nalokho, ukuveza amabhodlela okusebenza, ukuphoqelela uhlelo ukwenza amaphutha.
Ngokubona kwami, uhlelo luphumelele izivivinyo. Lokhu ngikusho ngokuzethemba ngoba ngesikhathi sokubhala lesi sihloko, isixazululo uvakashele amagumbi okuhlangana angempela ayishumi nambili amakhasimende ethu. Ukungasebenzi kahle kwe-automation kwabonwa kuphela ezimeni zokwephulwa kwemithetho enconyiwe yokusebenza. Ikakhulukazi, ibanga elincane eliya kubahlanganyeli abaseduze. Uma uhlezi eduze kakhulu nekhamera, ngaphansi kwemitha, i-microphone array ngeke ikwazi ukukubona futhi ilensi ngeke ikwazi ukukulandela.
Ngaphezu kwebanga, kunenye imfuneko - ukuphakama kwekhamera.
Uma ikhamera ifakwe iphansi kakhulu, kungase kuvele izinkinga zokuma kwezwi. Inketho ngaphansi kwe-TV, ngeshwa, ayizange isebenze.
Kodwa ukufaka isistimu ngaphezulu kwedivayisi yokubonisa kuyindlela ekahle yokuthi idivayisi isebenze. Ishalofu lekhamera lifakiwe; okokukhweza odongeni kuphela okusekelwa njengokujwayelekile.
Isebenza kanjani i-SmartCam A12 Voice Tracking
Amalensi e-PTZ ayinhloko anezindima ezilinganayo - umsebenzi wawo ukulandelela abethuli ngokushintshana nokubonisa uhlelo lonke. Izibalo zesithombe esiphelele segumbi kanye nokunqunywa kwebanga lezinto kwenziwa kusetshenziswa imifudlana yevidiyo etholwe kumakhamera amabili ahlanganiswe nesisekelo sohlelo. Lesi sici sikuvumela ukuthi unciphise isikhathi sokusabela selensi lapho ushintsha isipika sibe imizuzwana engu-1-2. Ikhamera iyakwazi ukushintshanisa ababambiqhaza ngesigqi esikhululekile, ngisho noma beshintshana ngemisho emifushane.
Ukuboniswa kwevidiyo kokusebenza kwesistimu kubonisa ngokugcwele ukusebenza . Kepha, kulabo abangakayibukeli ividiyo, ngizochaza ngamagama umgomo wokusebenza kwe-automation:
- Igumbi alinalutho: elinye lamalensi libonisa uhlelo olujwayelekile, elesibili selilungile - lilinde abantu
- Abantu bangena egumbini futhi bahlale ezihlalweni zabo: ilensi yamahhala ithola ababambiqhaza ababili abeqisayo futhi ifake isithombe esibazungezile, inqamule ingxenye engenalutho yegumbi.
- Ngenkathi abantu behamba, amalensi ayashintshana ngokulandela wonke umuntu osegumbini, abagcine phakathi nendawo yohlaka.
- Isikhulumi siqala ukukhuluma: ilensi iyasebenza, ilungiswe ohlelweni olujwayelekile. Eyesibili iqondiswe kusipika, bese ingena kumodi yokusakaza
- Isipikha siyashintsha: ilensi elungiselwe isipikha sokuqala iyasebenza, futhi ilensi yesibili yehlisa ishothi ebanzi bese iqondana nesipika esisha.
- Ngesikhathi sokushintsha isithombe sisuke kusipikha sokuqala siye kwesesibili, ilensi yamahhala ilungiswa ngokushesha ibe nohlelo olujwayelekile lwegumbi.
- Uma wonke umuntu ethule, ilensi yamahhala izobonisa icebo elivamile elenziwe ngomumo ngaphandle kokubambezeleka
- Uma isipikha sishintsha futhi, ilensi yamahhala izomfuna
isiphetho
Ngokubona kwami, lesi sixazululo, esethulwa kwa-ISE nase-ISR ngonyaka odlule, sisondeza ubuchwepheshe obuphezulu - uma kungenjalo kubantu, khona-ke ebhizinisini ngokuqinisekile. Kuyacaca ukuthi ngama-ruble ayizinkulungwane ezingu-400, abantu abambalwa bazothenga "ithoyizi" elinjalo ekhaya, kodwa ibhizinisi, umhlangano wevidiyo wenkampani, lokhu kuyisixazululo esingabizi kakhulu futhi esikahle senkinga yokuhlonza ikhamera ngokuzenzakalelayo.
Njengoba kunikezwe ukuguquguquka , isistimu ingasetshenziswa njengesixazululo kusukela ekuqaleni, noma njengesandiso sokusebenza kwengqalasizinda ekhona yenkomfa ngevidiyo. Ukuxhuma nge-HDMI kuyisinyathelo esikhulu esiya kumsebenzisi, ngokungafani nezinhlelo zobunikazi zabakhiqizi abachazwe ngenhla.
