Holder camera shooting intelligent analysis teaching recording and playing all-in-one machine

Abstract

The invention discloses a holder camera shooting intelligent analysis teaching recording and playing all-in-one machine. The all-in-one machine comprises a holder and a camera unit carried on the holder. The camera unit comprises a camera which is used for collecting audio and video signals of a teaching scene; a host processing module which is used for receiving the audio and video signals and encoding and packaging the audio and video signals, wherein the packaged audio and video signals are stored locally on one hand and are pushed out in a streaming media form through the 4G network module on the other hand; a video analysis DSP module which is used for receiving the video signal, carrying out classification and identification on a target in the video signal, outputting a motion control signal to the holder control module according to a classification and identification result, and outputting a camera focusing signal to the camera control module so as to track the target in real time. According to the invention, the camera and the holder are integrated, the specific target behavior in the classroom scene is identified and analyzed, and the real-time transmission of the 4G network is combined, so that the intelligent degree of the teaching classroom is further improved.

Description

technical field [0001] The invention relates to the field of intelligent teaching, in particular to a pan-tilt camera intelligent analysis teaching recording and broadcasting all-in-one machine. [0002] technical background [0003] With the continuous development of computer vision and network streaming media technology, coupled with the continuous maturity of cloud computing, mobile Internet and big data analysis technology, its deep integration with modern education has given birth to a new generation of intelligent teaching recording and broadcasting system. [0004] The intelligent recording and broadcasting system generally adopts the method of separating the camera from the recording and broadcasting host, that is, the front end uses an independent camera to obtain video data, and inputs the video into the recording and broadcasting host through SDI and HDMI, etc. After the recording and broadcasting host processes the video data, a On the one hand, the video is store...

AI Technical Summary

Problems solved by technology

[0005] The camera is separated from the recording and broadcasting host, resulting in a large space occupation and insufficient compact structure; the network live broadcast mode based on WiFi or Ethernet has greatly restricted its applicable scenarios; in the past, the recording and broadcasting host was only responsible for recording and live broadcasting, and did not integrate The corresponding intelligent recognition algorithm will take additional time in post-processing
