Virtual attendance system based on remote attendance equipment

Abstract

The invention discloses remote attendance equipment and a corresponding remote attendance system. In the remote attendance equipment, a moving part receives a control command from a control part; a video part collects on-site images and sends the images to a cloud server; an audio part collects on-site sounds and sends the sounds to the cloud server; and the audio and video parts receive audio and video signals from the cloud server for restoring sounds and images. The audio part adopts a multi-microphone array for collecting the on-site sounds. Sounds collected by each microphone are subjected to primary filtering, audio frequencies are subjected to wave beam processing for forming single signals, and then the single signals are subjected to secondary filtering, and thus the position of a main sound source is obtained. According to the invention, a user is allowed to start the remote attendance equipment at any place capable of accessing to the Internet, and to appear at an expected place for on-site communication. Thus, the user is prevented from frequently attending various on-site conferences, and wasted travel time is reduced.

Description

technical field [0001] The invention relates to a virtual presence system, in particular to a virtual presence system based on remote presence equipment, and belongs to the technical field of teleconferencing. Background technique [0002] At present, computer teleconferencing systems have been widely used in various fields of social life. At the same time, with the continuous development of electronic information technology, robot technology has also begun to enter the field of teleconferencing technology. [0003] According to relevant media reports, the American company Anybots has developed a remote monitoring robot called QB. The height of the QB robot is variable, the highest is about 1.75 meters, which is equivalent to the normal height of an adult. The QB robot moves around on two wheels at the speed of a human walking and balances itself as it moves. The QB robot can "see" the surrounding objects through a 5-megapixel camera in one eye and a lower-resolution came...

AI Technical Summary

Problems solved by technology

[0004] However, the QB robot has a limited range of movement and cannot automatically locate the main sound source, resulting in the remote controller sometimes not being able to see the scene

Due to the relatively expensive price, there are only limited users currently using it, so the usage rate of this QB robot is still relatively low
