Preferably, in the step S4, while holder monitor camera captures sound source position, pass through alarm
Issue alarm sound.
The present invention is a kind of sound fixation and recognition method for detecting, is mainly used in the alarm detecting of household PTZ camera
On.Solid space microphone array is integrated in PTZ camera, and sound source is carried out by special speech sample recognizer
It analyzes and determines, quickly carries out localization of sound source position, and candid photograph image is carried out to picture at this and reports cloud.
Mainly comprise the steps that microphone array passes through the sound source (people to environment when opening sound detecting/warning function
Sound, noise etc.) it is sampled, noise is filtered out, analyzes and determines sound source, precise positioning position of human body rapidly.Camera pan-tilt rotation
To sound source position, candid photograph alarm is carried out to picture, cloud is reported to, is then pushed in user hand.
In PTZ camera integrated microphone array, it can be determined that in space the position of sound source, is quickly identified, thus
Effectively quick positioning video picture position, instantaneously captures image alarm.
(2) 360 ° of microphone arrays of horizontal annular are combined with vertical ring-shaped 360 ° of microphone arrays, and comprehensive no dead angle is fixed
Sound source in the environment of position.Level of microphone array is placed on the scene of desktop primarily directed to PTZ camera, when sound source is in level
It is issued under environment, judgement sound source position can be identified by level of microphone array；Vertical microphone array primarily directed to
PTZ camera mounts or lifts scene, can combine microphone array by horizontal+vertical and judge sound source position to analyze identification
It sets.(as shown in figure)
(3) microphone array detect principle: under level environment, when people said in short, if in 8 MIC MIC1 this
When it is nearest apart from sound source.The voice signal energy that so MIC1 is sampled is most strong, and the voice signal energy that MIC3 is sampled is most weak,
The voice signal energy that MIC2, MIC4 are sampled is between MIC1 and MIC3.Again by special algorithm, can thus identify quickly
Judge the position that sound issues.Similarly, the sound in solid space is also to be analyzed in this way.(as shown in Figure 2)
