Isihloko sokulandela umthathi-nxaxheba othethayo kwinkomfa yevidiyo siye safumana amandla kule minyaka imbalwa idlulileyo. Itekhnoloji yenze ukuba kube nokwenzeka ukuphumeza i-algorithms entsonkothileyo yokucubungula ulwazi lweaudio/yevidiyo ngexesha lokwenyani, nto leyo eyabangela ukuba iPolycom, phantse kwiminyaka eyi-10 eyadlulayo, yazise isisombululo sokuqala sehlabathi ngokulandela umkhondo wesithethi esikrelekrele ngokuzenzekelayo. Kangangeminyaka emininzi bakwazile ukuhlala bengabanikazi kuphela besisombululo esinjalo, kodwa uCisco akazange alinde ixesha elide kwaye azise kwimarike inguqulelo yabo yenkqubo ekrelekrele yeekhamera ezimbini, eyayingumntu okhuphisana ngokufanelekileyo kwisisombululo esivela kwiPolycom. Kangangeminyaka emininzi, eli candelo le-videoconferencing lalinqunyanyiswa bubuchule babantu abaninzi yobunini iimveliso, kodwa eli nqaku linikezelwe kweyokuqala jikelele isisombululo sekhamera yesikhokelo ngelizwi, iyahambelana nezixhobo zombini kunye nesoftware yenkomfa yevidiyo.
Ngaphambi kokuba ndiqhubele phambili ekuchazeni izisombululo kunye nokubonisa amandla, ndifuna ukuqaphela isiganeko esibalulekileyo:
Ndiwongekile ukuba ndiveze kuluntu lwaseHabra , ezinikezelwe kwizisombululo ze-videoconferencing (VCC). Ngoku, ngenxa yemigudu edibeneyo (eyam kunye ne-UFO), inekhaya layo eHabré, kwaye ndimema wonke umntu obandakanyekayo kwesi sihloko sibanzi nesikhoyo ukuba abhalise kuso .
Iimeko ezimbini zokukhomba ikhamera kwisithethi
Okwangoku, abahlanganisi bezisombululo zenkomfa yevidiyo bazikhethela iindlela ezimbini ezahlukeneyo zokuphumeza umsebenzi wokujolisa kumbonisi:
- Okuzenzekelayo-Bukrelekrele
- Semi-automatic - programmable
Inketho yokuqala zizisombululo zeCisco, Polycom kunye nabanye abavelisi; siza kuziqwalasela ngezantsi. Apha sijongene ne-automation epheleleyo yokukhomba ikhamera kumthathi-nxaxheba othethayo kwinkomfa yevidiyo. Ii-algorithms ezizodwa zokusetyenzwa kwesandi/imiqondiso yevidiyo ivumela ikhamera ukuba ikhethe indawo efunekayo ngokuzimeleyo.
Inketho yesibini ziinkqubo ezizenzekelayo ezisekwe kubalawuli abahlukeneyo bolawulo lwangaphandle; asiyi kuziqwalasela ngokweenkcukacha, kuba Eli nqaku linikezelwe ngokukodwa ekulandeleleni okuzenzekelayo kwezithethi.
Kukho abaxhasi abambalwa bemeko yesibini yokuphumeza ukukhomba ikhamera, kwaye kukho izizathu zoku. Abahlanganisi abanamava bayaqonda ukuba izisombululo ezikrelekrele ezivela kwiPolycom kunye neCisco zifuna iimeko ezifanelekileyo zokusebenza ukuze i-automation isebenze ngokufanelekileyo. Kodwa akusoloko kunokwenzeka ukubonelela ngeemeko ezinjalo, ngoko ukusebenza kwenkqubo ngamanye amaxesha kuqinisekiswa sisisombululo esilandelayo kwingxaki yokukhomba ikhamera:
1. Zonke izinto ezifunekayo (izikhundla ze-PTZ kunye ne-optical zoom factor) zingeniswa ngesandla kwangaphambili kwimemori yekhamera (okanye ngamanye amaxesha kumlawuli wokulawula). Njengomthetho, esi sisicwangciso esiqhelekileyo segumbi lokuhlangana, kunye nombono womthathi-nxaxheba ngamnye wenkomfa kwimodi ye-portrait.
2. Emva koko, abaqalisi bokubiza i-preset efunekayo bafakwe kwiindawo ezichaziweyo - ezi zi-microphone consoles okanye amaqhosha erediyo, ngokubanzi, nasiphi na isixhobo esinokunika umlawuli olawulayo ngomqondiso owuqondayo.
3. Umlawuli wolawulo ucwangciswe ngendlela yokuba umqalisi ngamnye abe ne-preset yakhe. Isicwangciso ngokubanzi segumbi - bonke abaqalisi bacinyiwe.
Ngenxa yoko, xa usebenzisa inkqubo ye-congress, umzekelo, kunye nomlawuli olawulayo, isithethi, ngaphambi kokuba siqalise intetho yakhe, sivula ikhonsoli yakhe yombhobho. Inkqubo yokulawula ngokukhawuleza iqhuba indawo yekhamera egciniweyo.
Le meko isebenza ngokungenasiphako - inkqubo ayifuni ukwenza unxantathu welizwi kunye nohlalutyo lwevidiyo. Ndicofe iqhosha kwaye ukusetha kwangaphambili kwasebenza, akukho kulibaziseka okanye iziphumo zobuxoki.
Iinkqubo zokulawula kunye ne-automation zisetyenziselwa kumagumbi amakhulu, anzima, apho ngamanye amaxesha kungekho enye, kodwa iikhamera zevidiyo ezininzi zifakwe. Ewe, kumagumbi okuhlangana amancinci naphakathi, iinkqubo ezizenzekelayo zifanelekile (ukuba unohlahlo lwabiwo-mali).
Masiqale ngootata baseseko.
Umlawuli we-Polycom EagleEye
Esi sisombululo sakha sadala imvakalelo kwindawo yenkomfa yevidiyo. UMlawuli we-Polycom EagleEye yaba sisisombululo sokuqala kwinkalo yesikhokelo sekhamera ehlakaniphile. Isisombululo siquka iyunithi yesiseko soMlawuli we-EagleEye kunye neekhamera ezimbini. Ubunqabileyo bokuphunyezwa kokuqala kukuba ikhamera enye yabelwe kuphela kwimbono esondeleyo yesithethi, kwaye okwesibini - kwisicwangciso esiqhelekileyo segumbi lentlanganiso. Kwangaxeshanye, ikhamera yesicwangciso ngokubanzi inokubekwa ngokwahlukileyo ngokupheleleyo kwisiseko kwenye indawo kwigumbi lentlanganiso - ayibandakanyekanga ngokuthe ngqo kwinkqubo yokhokelo oluzenzekelayo.
Inkqubo isebenza ngolu hlobo lulandelayo:
- Ikhamera yegumbi ngokubanzi iyasebenza - wonke umntu uthe cwaka
- Isithethi siqala ukuthetha-i-microphone array ithatha ilizwi, ikhamera ibheka kwisandi isebenzisa iteknoloji enelungelo elilodwa lomenzi obandakanya unxantathu welizwi. Ikhamera ngokubanzi isasebenza
- Ikhamera ephambili iqala ukukhangela umthombo wesandi, iqhuba uhlalutyo lwevidiyo. Inkqubo ichonga isithethi ngoqhagamshelo lwempumlo yomlomo, isakhelo somfanekiso wesithethi kwaye ibonise umlambo osuka kwikhamera enkulu.
- Isithethi siyatshintsha. Uluhlu lwemakrofoni luyaqonda ukuba ilizwi livela kwenye indawo. Isicwangciso ngokubanzi sivulwa kwakhona.
- Kwaye emva koko kwisangqa, ukuqala kwinqaku lesi-2
- Ukuba isithethi esitsha sikwisakhelo kunye nesangaphambili, inkqubo yenza utshintsho lwendawo "eshushu" ngaphandle kokutshintsha ukuhamba okusebenzayo ukuya kukudubula ngokubanzi.
I-downside, ngokombono wam, kubukho bekhamera enye kuphela. Oku kubangela ukulibaziseka okukhulu xa kutshintshwa izithethi. Kwaye ngalo lonke ixesha ngexesha lokukhomba, inkqubo ijika kwisicwangciso esiqhelekileyo segumbi - ngexesha lencoko edlamkileyo, oku kuqhwanyaza kuqala ukucaphukisa.
Polycom EagleEye uMlawuli II
Olu luguqulelo lwesibini lwesisombululo esivela kwiPolycom, ekhutshwe kutsha nje. Umgaqo wokusebenza uye watshintsha kwaye uye waba njengesisombululo esivela kwiCisco. Ngoku zombini iikhamera ze-PTZ zezona ziphambili kwaye zisebenza ngokutshintsha ngaphandle komthungo ukusuka kumbonisi omnye ukuya komnye. Uyilo oluqhelekileyo lwegumbi lokuhlangana ngoku lubanjwe yikhamera ehlukeneyo ehlanganiswe kumzimba weyunithi yesiseko se-EagleEye Director II. Ngesizathu esithile, umlambo ovela kule khamera ebanzi uboniswa kwifestile eyongezelelweyo kwikona yesikrini, ehlala i-1/9 yomlambo oyintloko. Umgaqo wokumisa uyafana - unxantathu welizwi kunye nohlalutyo lomjelo wevidiyo. Kwaye iibhotile ziyafana: ukuba inkqubo ayiboni umlomo othethayo, ikhamera ayiyi kujolisa. Kwaye le meko inokwenzeka kaninzi - isithethi siye sajika, isithethi siye sajika, isithethi sithetha nge-ventriloquist, isithethi sivale umlomo waso ngesandla okanye uxwebhu.
Zombini iividiyo zentengiso zidutyulwe ngokufanelekileyo - abantu aba-2 bathetha ngokutshintshana, kwaye bavula imilomo yabo ngokungathi bakwidinga kunye nengcali yentetho. Kodwa nakwiimeko ezinjalo ezisulungekileyo kukho ukulibaziseka okukhulu kakhulu. Kodwa ukuyila akunakulunga - umfanekiso otofotofo otofotofo.
Cisco TelePresence SpeakerTrack 60
Ukuchaza esi sisombululo, ndiya kusebenzisa isicatshulwa esivela kwincwadana esemthethweni.
I-SpeakerTrack 60 ithatha indlela ekhethekileyo yeekhamera ezimbini ukutshintshela ngokukhawuleza phakathi kwabathathi-nxaxheba. Enye ikhamera ifumana ngokukhawuleza umbonisi osebenzayo, ngelixa enye ikhangela kwaye ibonise umbonisi olandelayo. I-MultiSpeaker feature inqanda ukutshintsha okungeyomfuneko ukuba isithethi esilandelayo sele sikhona kwisakhelo sangoku.
Ngelishwa, andizange ndibe nethuba lokuvavanya i-SpeakerTrack 60 ngokwam. Ngoko ke, izigqibo kufuneka zenziwe ngokusekelwe kwimbono "ephuma kwintsimi" kwaye isekelwe kwiziphumo zohlalutyo lwevidiyo yokubonisa engezantsi. Ndibale ukulibaziseka okukhulu malunga nemizuzwana eyi-8 xa ndikhomba umsasazi omtsha. Umndilili wokulibaziseka ibiyi 2-3 seconds, ukugweba ngevidiyo.
I-HUAWEI Intelligent Tracking Video Camera VPT300
Ndifumene esi sisombululo sivela kuHuawei ngengozi. Inkqubo ixabisa malunga ne-9K yeedola. Isebenza kuphela ngeetheminali zeHuawei. Abaphuhlisi bongeze eyabo "iqhinga" - uyilo lwevidiyo kwizithethi ezibini kwiscreen esinye ukuba akukho mntu wumbi egumbini. Ngokweempawu kunye nokusebenza okubhengeziweyo, olu luguqulelo olunomdla kakhulu lwenkqubo yokhokelo oluzenzekelayo. Kodwa, ngelishwa, andizange ndifumane nto yedemo. Ividiyo kuphela evele kwesi sihloko yayiyividiyo ehleliweyo yophononongo lwesisombululo, ngaphandle kwesandi sokuqala, esisetelwe kumculo. Ngaloo ndlela, kwakungenakwenzeka ukuvavanya umgangatho wenkqubo. Ngesi sizathu, andiyi kuqwalasela olu khetho.
Ndiyabona ukuba uHuawei unebhlog esebenzayo kuHabré - mhlawumbi oogxa bakhe baya kuba nakho ukupapasha ulwazi oluluncedo kule mveliso.
Entsha - isisombululo jikelele
- i-monoblock, kubandakanywa iikhamera ezimbini ze-PTZ zokulandelela izithethi, iikhamera ezimbini ezakhelwe ngaphakathi zokuhlalutya ukuhlelwa ngokubanzi kwegumbi, kunye ne-microphone array eyakhelwe kwisiseko secala - njengoko ubona, akukho nto ininzi kwaye izakhiwo eziethe-ethe ezifana nezo zabachasi.
Ngaphambi kokuba ndiqale ukuchaza imveliso entsha, ndiza kudibanisa iimpawu kunye neempawu zezisombululo ezivela eCisco nasePolycom ukuze ndithelekise. kunye nezibonelelo ezikhoyo.

Njengeenzuzo ezimbini eziphambili nezingenakuphikiswa zesisombululo SmartCam A12 Voice Tracking Ndifumene:
- Uqhagamshelo oluguquguqukayo - nge-HDMI, inkqubo idibanisa kunye ne-hardware kunye ne-software ye-terminal ye-conferencing ye-software
- Ixabiso eliphantsi - Ngokusebenza okufanayo, i-A12VT ifikeleleka ngamaxesha amaninzi kuhlahlo lwabiwo-mali kunezindululo ezichazwe ngasentla.
Ukubonisa indlela esebenza ngayo inkqubo, sirekhode uphononongo lwevidiyo. Umsebenzi wawungeyontengiso ingako njengoko usebenza. Ke ngoko, ividiyo ayinazo iipathos zevidiyo yePolycom yokuthengisa. Indawo ebikhethelwe umboniso ibingeyoofisi yabameli, kodwa ligumbi leentlanganiso elebhu yeqabane lethu, inkampani ye-IPMatika.
Injongo yam yayingekho ukufihla iziphene zenkqubo, kodwa, ngokuchaseneyo, ukuveza imiqobo yokusebenza, ukunyanzela inkqubo ukuba yenze iimpazamo.
Ngokombono wam, inkqubo iphumelele iimvavanyo ngempumelelo. Ndithetha oku ngokuzithemba kuba ngexesha lokubhala eli nqaku, isisombululo undwendwele amagumbi okuhlangana okwenene alishumi elinesibini abathengi bethu. Ukungasebenzi kakuhle kwe-automation kwabonwa ngokukodwa kwiimeko zokuphulwa kwemithetho yokusebenza ecetyiswayo. Ngokukodwa, umgama omncinci kubathathi-nxaxheba abakufutshane. Ukuba uhlala kufutshane kakhulu nekhamera, ngaphantsi kwemitha, uluhlu lwemakrofoni aluyi kukwazi ukukubona kwaye ilensi ayizukwazi ukukulandela.
Ukongeza kumgama, kukho enye imfuneko - ukuphakama kwekhamera.
Ukuba ikhamera ifakwe iphantsi kakhulu, iingxaki zokuma kwelizwi zinokwenzeka. Inketho phantsi kweTV, ngelishwa, ayizange isebenze.
Kodwa ukufaka inkqubo ngaphezulu kwesixhobo sokubonisa yindlela efanelekileyo yokuba isixhobo sisebenze. Ishelufu yekhamera ibandakanyiwe; kukunyuka kodonga kuphela kuxhaswe njengomgangatho.
Isebenza njani iSmartCam A12 Voice Tracking
Iilensi eziphambili ze-PTZ zineendima ezilinganayo - umsebenzi wazo kukulandelela ababonisi kunye nokubonisa isicwangciso esipheleleyo. Ukuhlaziywa komfanekiso opheleleyo kwigumbi kunye nokuzimisela komgama kwizinto zenziwa ngokusebenzisa imijelo yevidiyo efunyenwe kwiikhamera ezimbini ezidibeneyo kwisiseko senkqubo. Eli nqaku likuvumela ukuba unciphise ixesha lokuphendula kwi-lens xa utshintsha isithethi ukuya kwi-1-2 imizuzwana. Ikhamera iyakwazi ukutshintshana phakathi kwabathathi-nxaxheba ngesigqi esikhululekile, nokuba batshintshiselana ngezivakalisi ezifutshane.
Umboniso wevidiyo wokusebenza kwenkqubo ubonisa ngokupheleleyo ukusebenza . Kodwa, kwabo bangakhange bayibukele le vidiyo, ndiza kuchaza ngamagama umgaqo wokusebenza kwe-automation:
- Igumbi alinalutho: enye yeelensi ibonisa isicwangciso esiqhelekileyo, okwesibini sikulungele - silinde abantu
- Abantu bangena egumbini kwaye bathathe izihlalo zabo: i-lens yasimahla ifumana abathathi-nxaxheba ababini abagqithisayo kwaye yenze isakhelo somfanekiso obajikelezileyo, inqumle indawo engenanto yegumbi.
- Ngelixa abantu beshukumayo, iilensi ziyatshintshana zilandelela wonke umntu osegumbini, zibagcine kumbindi wesakhelo.
- Isithethi siqala ukuthetha: i-lens iyasebenza, ilungelelaniswe kwisicwangciso esiqhelekileyo. Eyesibini ijolise kwisithethi, kwaye emva koko iya kwimo yosasazo
- Isithethi siyatshintsha: ilens elungelelanisiweyo kwisithethi sokuqala iyasebenza, kwaye eyesibini ilens iwisa umfanekiso obanzi kwaye ilungelelanise isithethi esitsha.
- Ngomzuzu wokutshintsha umfanekiso ukusuka kwisithethi sokuqala ukuya kwisibini, i-lens yamahhala ilungiswa ngokukhawuleza kwisicwangciso esiqhelekileyo segumbi.
- Ukuba wonke umntu uthule, i-lens yamahhala iya kubonisa isicwangciso esiqhelekileyo esenziwe ngokulungele ngaphandle kokulibaziseka
- Ukuba isithethi sitshintsha kwakhona, i-lens yamahhala iya kumfuna
isiphelo
Ngokombono wam, esi sisombululo, esiboniswe kwi-ISE kunye ne-ISR kunyaka odlulileyo, sisondeza iteknoloji ephakamileyo - ukuba kungekhona kubantu, ngoko-shishini ngokuqinisekileyo. Kucacile ukuba kwii-ruble ezingama-400 amawaka, abantu abambalwa baya kuthenga "ithoyizi" enjalo ekhaya, kodwa kwishishini, kwinkomfa yevidiyo yenkampani, esi sisisombululo esifikelelekayo kwaye esifanelekileyo kwingxaki yokujolisa ngokuzenzekelayo ikhamera.
Ngenxa yokuguquguquka , inkqubo ingasetyenziselwa njengesisombululo ukusuka ekuqaleni, okanye njengokwandiswa kokusebenza kwesiseko senkomfa yevidiyo ekhoyo. Ukudibanisa nge-HDMI linyathelo elikhulu kumsebenzisi, ngokungafaniyo neenkqubo zobunikazi zabavelisi abachazwe ngasentla.
