Description
Technical field
The present invention relates to a kind of voice acquisition device, more particularly, to a kind of remote speech of sound image combined positioning
Harvester.
Background technology
In fields such as security, security protections, all kinds of video monitoring systems have been used widely.Rely on all kinds of videos
Monitoring system, can be confirmed to related personnel in long-distance video, be screened.Utilizing video monitoring system
If being gathered using language, dialog information by remote speech when carrying out remote suspect's confirmation, screening,
Operating efficiency can be leveraged.But remote speech collection is carried out under actual environment background noise conditions still
With high difficulty.
Due to the presence of ambient noise, remote speech must be protected when gathering using the high directivity of harvester
Demonstrate,prove the remote speech quality of collection.Current remote speech harvester is mainly using the rifle of interference tubular construction
Formula microphone forms high directivity.

There is a problem of being difficult synchronous during mark speaker, will also cause Design of Monitoring and Control System to use upper inconvenience.
Microphone array is made up of multiple microphones according to certain topological structure, can be by beamforming algorithm to not
Signal on equidirectional forms different responses, namely array space directional property, make array microphone that there is sound
The function such as source positioning and tracking, voice extraction and separation and denoising, so as to improve the voice under complex background
Signal quality, making up isolated microphone cannot obtain defect with utilization space information, and can avoid using machinery
Tumbler carrys out alignment target speaker.
The model domain compensation that Chinese patent ZL 2013102011025 is disclosed in a kind of remote speech identification is newly square
Method, the method is proposed in simulating chamber for the difficulty in microphone array remote speech collection indoors and identification
Reverberation acoustic enviroment, and pass through be input into interior space size generate diverse location room shock response sequence
Row, so as to the compensation that indoor remote speech is carried out in model domain improves collection and identifying processing performance.
But the outdoor scene remote speech for fields such as security, security protections gathers occasion, and the required voice that carries out is adopted
Speaker's object distance of collection is much larger than indoor application scene, and there is serious ambient noise.Now, merely
It is difficult to obtain speaker direction so as to carry out speech enhan-cement and collection by microphone array algorithm.
The content of the invention
For the difficult point of voice collecting under remote, noise background, enter with reference to video frequency pick-up head, microphone array
The sound image combined determination target speaker of row, so as to solve to use camera, high directivity microphone or Mike merely
