Remote sound collection device, monitoring device and remote sound collection method

Abstract

The invention discloses a remote sound collection device and a remote sound collection method. The remote sound collection device comprises a sound pickup unit module, single-channel noise reducing processing modules, a microphone array processing module and a directive processing module; the sound pickup unit module comprises a reflective surface and a plurality of microphone components which arearranged in the center of the reflective surface; the output end of each sensor component is connected to the input end of the single-channel noise reducing processing module corresponding to the microphone component; the output end of each single-channel noise reducing processing module is connected to the input end of the microphone array processing module; and the output end of the microphonearray processing module is connected to the output end of the directive processing module.

Description

technical field [0001] The invention relates to a remote sound collection device and a remote sound collection method. Background technique [0002] Various video surveillance or video acquisition systems have been widely used in security, security, interview and other fields. Relying on various video surveillance or video capture systems, it is possible to accurately capture relevant personnel in long-distance videos, but it is difficult to perform long-distance voice capture when using video surveillance systems for long-distance shooting. The monitoring system can use language and dialogue information to analyze suspects, and the video acquisition system can record video and voice synchronously, which will greatly affect work efficiency. However, long-distance voice collection can be realized under the background noise conditions of the actual environment, but the clarity is still low. Contents of the invention [0003] The technical problem to be solved by the presen...
