Abstract

The invention discloses a real-time positioning recording device and a real-time positioning recording method; the real-time positioning recording device comprises a pickup matrix, a camera, a camera focus positioning and audio processing module, a multimedia file module, and a network sending module; the camera focus positioning and audio processing module comprises a camera positioning analysis module, a pickup audio filter module and an audio processing module; the pickup matrix comprises multiple pickups; after the camera starts to work, the camera positioning analysis module determines a focus, fallen on the pickup matrix, of the camera; the pickup matrix sends audio information to the pickup audio filter module and the audio processing module according to the focus; and the audio processing module respectively sends the processed audio file to the multimedia file module and the network sending module. According to the device and the method disclosed by the invention, a set of distributed pickup array is designed, thereby positioning a real-time pickup synthesizer according to the focus of the camera, determining sound synthesis collected by the pickup array in real time according to a position, fallen in a space, of the focus of the camera, and correlating to a video signal in real time.

Description

technical field [0001] The invention relates to the technical field of sound source location and acquisition, in particular to a real-time location recording device and method. Background technique [0002] Acoustic source localization acquisition technology is a new branch of target localization technology, which has broad application prospects and scientific research value, and has received extensive attention and research in recent years. In a set target area, such as classrooms, conference rooms, and squares, during heated discussions and speeches, sound collection must have a trade-off. Observers outside the video want to see what the video camera is always pointing at. Sound at one point, while ignoring or reducing the sound outside the focus of the camera. [0003] The Chinese invention patent with the publication number CN103414988A discloses an indoor sound reinforcement recording device and a voice tracking adjustment method. The method includes the following step...
