At present, user has a meeting in office and when needing video camera, a kind of style of shooting be staff for a long time with Track is shot, and another style of shooting is by fixed camera establishing shot；The first style of shooting has shooting in shooting Dead angle, in addition manually shoots meeting waste of manpower for a long time and shooting effect is also not fully up to expectations；Although the first style of shooting The prolonged captured in real-time of energy, but once start shooting, then middle to interrupt, more wasteful resource.
The content of the invention
Based on technical problem existing for background technology, the present invention proposes a kind of video acquisition side based on sound source position Method；
A kind of video capture method based on sound source position proposed by the present invention, including：
S1, the real-time audio decibel for obtaining each predeterminable area, are denoted as D1、D2…Dn；
S2, by D1、D2…DnWith default decibel threshold D0It is compared, by D1、D2…DnIn be more than D0Real-time audio point The corresponding predeterminable area of shellfish is as first object region；
S3, the realaudio data for obtaining first object region, are denoted as V1、V2…Vi, wherein, i≤n；
S4, detection V1、V2…ViIn whether include voice, by V1、V2…ViIn comprising voice realaudio data correspond to First object region as the second target area；
S5, carry out video acquisition to the second target area.
Preferably, step S1, specifically includes：Each preset areas is obtained by presetting decibel detection device in each predeterminable area The real-time audio decibel in domain.
Preferably, in step S1, the predeterminable area can be edited by user, and not overlapped each other between each predeterminable area.
Preferably, step S3, specifically includes：Pass through the preset audio harvester acquisition first object in each predeterminable area The realaudio data in region.
Preferably, in step S4, the detection V1、V2…ViIn whether include voice, specifically include；By V1、V2…ViWith Default voice audio data sample is compared, and detects V1、V2…ViIn whether include voice.
Preferably, step S5, specifically includes：By presetting at least one video acquisition device pair in each predeterminable area Second target area carries out video acquisition.
Preferably, step S5, further includes：When the time of video acquisition is carried out to the second target area every time no less than presetting Between.
Real-time audio decibel of the invention by obtaining each predeterminable area, by the real-time audio decibel of each predeterminable area and in advance If decibel threshold be compared, will be greater than the corresponding predeterminable area of real-time audio decibel of decibel threshold as first object area Domain, obtains the realaudio data in first object region, whether people is included in the realaudio data in detection first object region Sound, using in the realaudio data in first object region include voice the corresponding first object region of realaudio data as Second target area, video acquisition is carried out to the second target area.In this way, in the case of labor-saving, realize that no dead angle is real When video acquisition, when user has a meeting, automatical and efficient video acquisition can be carried out to the user that speaks, do not missed in any meetings Hold, increase user experience.
Brief description of the drawings
Fig. 1 is a kind of flow diagram of the video capture method based on sound source position proposed by the present invention.
Embodiment
Reference Fig. 1, a kind of video capture method based on sound source position proposed by the present invention, including：
Step S1, obtains the real-time audio decibel of each predeterminable area, is denoted as D1、D2…Dn, specifically include：By each pre- If presetting the real-time audio decibel that decibel detection device obtains each predeterminable area in region, the predeterminable area can be compiled by user Volume, and do not overlap each other between each predeterminable area.
In concrete scheme, decibel detection device is set in several predeterminable areas of user's setting, is detected and filled by decibel Put the real-time audio decibel for obtaining each predeterminable area.
Step S2, by D1、D2…DnWith default decibel threshold D0It is compared, by D1、D2…DnIn be more than D0Real-time sound The corresponding predeterminable area of frequency division shellfish is as first object region.
In concrete scheme, by the real-time audio decibel of each predeterminable area compared with default decibel threshold, so that Judge the interference for whether thering is sound to send in each predeterminable area and removing some tiny noises.
Step S3, obtains the realaudio data in first object region, is denoted as V1、V2…Vi, wherein, i≤n, specific bag Include：Pass through the realaudio data in the preset audio harvester acquisition first object region in each predeterminable area.
In concrete scheme, audio collecting device is set in several predeterminable areas of user's setting, is filled by audio collection Put the realaudio data for obtaining predeterminable area.
Step S4, by V1、V2…ViCompared with default voice audio data sample, V is detected1、V2…ViIn whether Comprising voice, by V1、V2…ViIn comprising voice the corresponding first object region of realaudio data as the second target area Domain.
In concrete scheme, the realaudio data in first object region and default voice audio data sample are carried out Compare, so as to whether have voice in detecting the realaudio data in first object region, in this way, removing the interference of non-voice.
Step S5, carries out video acquisition to the second target area, specifically includes：By being preset in each predeterminable area A few video acquisition device carries out the second target area video acquisition, and carries out video acquisition to the second target area every time Time be no less than preset time.
In concrete scheme, video acquisition device is set in several predeterminable areas of user's setting, is filled by video acquisition Put and video acquisition is carried out to the second target area, realize no dead angle real time video collection.
Present embodiment is by obtaining the real-time audio decibel of each predeterminable area, by the real-time audio decibel of each predeterminable area Compared with default decibel threshold, the corresponding predeterminable area of real-time audio decibel of decibel threshold is will be greater than as the first mesh Region is marked, the realaudio data in first object region is obtained, whether is wrapped in the realaudio data in detection first object region Containing voice, the corresponding first object region of realaudio data of voice will be included in the realaudio data in first object region As the second target area, video acquisition is carried out to the second target area.In this way, in the case of labor-saving, realize without dead Angle real time video collection, when user has a meeting, the automatical and efficient user to speaking of energy carries out video acquisition, does not miss any meeting Content is discussed, increases user experience.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto, Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
