Yealink definities

Acroniemen en termen uitgelegd

Yealink onderzoekt Yealinks vereenvoudigde uitleg van algemene zakelijke communicatietermen met betrekking tot de toepassing van drie belangrijke communicatieapparaten, IP-telefoons, videoconferentieapparatuur en headsets die draaien op Microsoft, Zoom en andere systemen, in zakelijke werkzaamheden.

Wat is Video Fence?

Tegenwoordig gebruiken steeds meer vergaderruimtes glazen wanden/scheidingswanden als achtergrond. Wanneer u de Al-functie gebruikt, is het eenvoudig om niet-deelnemers te selecteren, wat de optimale kijkervaring van externe deelnemers beïnvloedt. Yealink Video Hek is ontstaan. Door het detectiebereik van de camera te beperken (dat vrij kan worden aangepast naar behoefte), worden enkele interferentiefactoren die de trackingnauwkeurigheid beïnvloeden, zoals portretten die aan de muur hangen, reflecties op de glazen wand, enz., verwijderd. Binnen het geselecteerde bereik zal de Al-functie werken zoals verwacht.


Video Fence-functie implementatieproces


Enkele lens:

Yealink gebruikt trigonometrische functies op basis van lensparameters om de diepte te berekenen, dat wil zeggen de afstand tussen de camera en de deelnemer, en de proportionele relatiemethode om de breedte van de deelnemer tot de camera te berekenen, dat wil zeggen de werkelijke afstand tussen de persoon en de middellijn van de foto.


Gebruik een vaste-focuslens om alle hoofdframes te detecteren en filter op basis van de diepte en breedte die door de gebruiker zijn ingesteld. Mensen buiten het detectiebereik worden in de afbeelding omlijst door rode frames en mensen binnen het detectiebereik door groene frames.


Dubbele lenzen:

De diepte wordt berekend met behulp van trigonometrische functies en de breedte met behulp van fittingfuncties.


Twee lenzen met vaste focus: de dubbele lens bestaat uit twee lenzen met vaste focus (zoals SmartVision40) en de Video Fence-functie wordt geïmplementeerd volgens de hierboven genoemde implementatielogica voor één lens.


Zoom + vaste-focuslens: De dubbele lens bestaat uit een zoomlens en een vaste-focuslens. Een high-definition zoomlens met variabele vergroting wordt gebruikt voor detectie en de detectieresultaten worden vervolgens toegewezen aan de vaste-focuslens om nauwkeurigheid te garanderen en de implementatielogica van de vaste-focuslens wordt hergebruikt om de Video Fence-functie te implementeren.




Videohekwerk instelbaar bereik


Het diepte- en breedte-aanpassingsbereik van de video fence-functie verandert afhankelijk van het maximale zichtbare bereik van de camera en kan in principe de middelgrote en grote conferentieruimtes van Microsoft bestrijken. De diepte en breedte die verschillende camera's kunnen bestrijken (d.w.z. het instelbare bereik van de Video Fence) worden gedetailleerd in de onderstaande tabel.

De parameters worden in realtime van kracht en blijven geldig na een herstart, totdat u ze de volgende keer wijzigt en opslaat.



Effectweergave

De Video Fence-functie is effectief in de modi Auto Framing / Speaker Tracking / Multi Focus.

De Video Fence-functie onder Auto Framing is gebaseerd op een vaste-focuslens. De Video Fence-functie onder Speaker Tracking is gebaseerd op een vaste-focuslens. De Video Fence-functie onder Multi Focus is gebaseerd op een zoomlens.
