Table 2

Sound around detecting, is that periodically the sound of surrounding is monitored, and the purpose of monitoring, which mainly obtains, to be moved The cry of thing；After getting the cry of animal, it is possible to which the cry of animal is acquired.It is worth noting that, sounding and It is not necessarily an animal individual, it is likely that have multiple individuals, it will not be same sound source hair that can use sound cutting technique The sound gone out makes a distinction, specifically, be exactly the time point that different sounder status transformations are found out in continuous sound, so as to It is in time that the signal for belonging to different animals individual is separated；Sound cutting technique, the pattra leaves based on model can be utilized This algorithm, intersect the methods of likelihood ratio algorithm to realize.

Further, in order to obtain the simplicity of animal sounds, detecting the sound of surrounding includes：In sound around detecting Whether movable sound is had, if so, then gathering the movable sound.Here movable sound, refer to that sound signal intensity reaches certain The sound of degree；In the environment of surrounding, the general information of our generally known animal species, the intensity of phonation model of each species Enclosing to determine, that is to say, that the sound that audible signal intensity reaches minimum animal vocalization intensity can be directly collected, so as to Avoid collecting the sound of excessive non-animal, influence the correctness of matching.

In addition, when gathering sound, sound source direction can also be carried out to sound, the direction of collection is pointed to what sound was sent Orientation；Specifically, pick up facility when gathering sound, can use the modes such as microphone array, the sound is positioned, made Point to the orientation where sound in pickup direction.

While sound is gathered, it can also be taken pictures and/or be imaged, picture signal corresponding to collection and/or video Signal, picture signal and vision signal can be acquired according to the acquisition interval of setting；Similar, in collection picture signal And/or during vision signal, the direction of collection can be pointed to the direction in direction, i.e. sound source that sound is sent, determine method and sound The mode of source positioning is consistent.

First voiceprint is a kind of characteristic information of voice signal, and it includes but is not limited to MFCC in the present embodiment (Mel-Frequency Cepstral Coefficients, mel-frequency cepstrum coefficient), LPCC (Linear Predict Cepstral Coefficients, linear prediction residue error) etc. a kind of voiceprint that can distinguish different animals species. The first voiceprint is extracted from the acoustical signal of source, is extracted in the sound exactly sent from these each sound sources collected The parameters such as MFCC, LPCC, different animal species, itself MFCC and LPCC parameter is different.

After the first voiceprint of each source acoustical signal is extracted, by these voiceprints and each species word bank Sound-groove model in voiceprint storehouse is matched；When being matched, two kinds of possibility that the match is successful He it fails to match be present, With success, refer to that the first voiceprint matches with the sound-groove model in some voiceprint storehouse, now assert first vocal print Source acoustical signal corresponding to information is that the animal for belonging to animal species corresponding to this voiceprint storehouse issues；And match and lose Lose, then refer to can not find any one voiceprint storehouse for first voiceprint it is matched, in this case, can To establish a new species word bank based on this first voiceprint that it fails to match, this species word bank equally includes Voiceprint storehouse and multimedia information lib, train to obtain sound-groove model and be saved according to the first voiceprint of the source acoustical signal In the species voiceprint storehouse of the species word bank, and corresponding source acoustical signal is stored in the multimedia information lib of the species word bank In, while the information such as picture signal and/or vision signal, acquisition time, collecting location corresponding to preservation.

After the match is successful in the first voiceprint, then source acoustical signal corresponding to this first voiceprint is stored in first In multimedia information lib corresponding to the voiceprint voiceprint storehouse that the match is successful, each source sound in a multimedia information lib Signal individually preserves；, should if also being corresponded to when gathering the source acoustical signal and acquiring picture signal and/or vision signal Picture signal and/or vision signal preservation corresponding with the source acoustical signal concurrently gathered；Further, can also will be with collection The unidirectional picture signal of source acoustical signal and/or vision signal are corresponding to be preserved, the highly preferred mode of the present embodiment, be by with Collection source acoustical signal same time and the corresponding preservation of unidirectional picture signal and/or vision signal.

In addition, when preserving source acoustical signal and corresponding picture signal and/or vision signal, can also record Gather the time of signal；In addition to recording acquisition time, the place of collection can also be recorded, the definition of collecting location can be Position where the animal individual of sounding, the recording mode in this place can be various, can use the mode of mark, Coordinate system can be pre-established, collecting location is recorded as coordinate or coordinate range.And the determination of specific collecting location, It can be position taken pictures/imaged etc. from the position of the position of each collecting device, such as pick up facility.

, can be with when the match is successful for the sound-groove model in the first voiceprint of source acoustical signal and some voiceprint storehouse The voiceprint storehouse is updated with first voiceprint that the match is successful, i.e. root first voiceprint trains to obtain corresponding sound Line model.

The present embodiment to different animal species in addition to it can sort out, in respective species word bank, we Have been obtained for the not homologous acoustical signal for belonging to identical species；Because each animal individual is not only to send out an infrasonic sound, that is, Say, an animal individual is on the premise of multiple sound is sent, and its final result is all sound that an animal individual is sent, especially It is the sound sent the different time, the multimedia information lib of same species word bank can be stored in as different source acoustical signals In.So, multiple source acoustical signals of same animal individual will be preserved in same multimedia information lib；So in order to just In the individual amount of the same species of statistics, while multimedia database is established to each individual, so as to support to each animal The behavioral study of body, the second voiceprint of the source acoustical signal in the multimedia information lib in each species word bank can be carried out Then these source acoustical signals are clustered by analysis according to analysis result.

Specifically, the process of above-mentioned cluster can be described as following steps：By the source sound letter in each multimedia information lib Number the second voiceprint of voice signal fragment formed is compared two-by-two；From each comparison result, two gaps are selected The second minimum voiceprint, by its gap value compared with preset value；Result of the comparison is divided into two kinds of situations：It is first, poor It is more than preset value away from value, then stops comparing, processing procedure terminates；Second, gap value is less than preset value, now then by the two Voice signal fragment corresponding to two voiceprints synthesizes, then by all including the voice signal fragment after this synthesis Voice signal fragment be compared two-by-two again, the voiceprint two of the voice signal fragment from by each multimedia information lib Two are compared and start to repeat above step, until not having any two second sound signal piece in the multimedia information lib Untill gap value between section is less than preset value.At the end of analysis and processing procedure, due to the sound of each animal individual being believed Number fragment is merged, then now easily can count corresponding species according to the situation of the voice signal fragment after merging How many animal individual in word bank.The each animal individual identified is marked, the species word bank obtained according to cluster The corresponding relation of project and animal individual in the corresponding relation namely multimedia information lib of middle source acoustical signal and animal individual, will Animal individual corresponding to each project is recorded in " affiliated animal individual " row of multimedia information lib shown in table 2.

Further, Fig. 2 is refer to, the specific implementation step of cluster is as follows：

S104a, estimate each voice signal fragment feature samples set Gauss model (μ, Σ)：To voice signal Feature samples set { the X of fragment_i, i=1 ..., k }, according to the following formula calculate sample set mean μ and covariance Σ：

Wherein k represents the sample points in voice signal fragment, and i represents sample point index, feature samples X_iIt is column vector, (*)^TRepresent transposition operation.Feature includes but is not limited to the parameters such as MFCC or LPCC described in this implementation example.

S104b, calculate the Generalized Likelihood Ratio distance of all voice signal fragments between any two.Generalized Likelihood Ratio distance is every The product of the individual individually log-likelihood of voice signal fragment sample set by two independent voice signal fragments with being mixed Sample set log-likelihood ratio.The log-likelihood of sample set is that own in voice signal fragment sample set Log-likelihood sum of the sample point to Gauss model：

Wherein d represents sample vector dimension, | * | representing matrix determinant.

S104c, calculate similarity Δ BIC value of the Generalized Likelihood Ratio apart from two voice signal fragments corresponding to minimum value. Δ BIC subtracts 0.5 λ (d+0.5d (d+1)) logN with Generalized Likelihood Ratio distance and obtained, and λ is penalty threshold, and d ties up for sample vector Number, N are sample number total in two voice signal fragments.If Δ BIC is less than 0, merge two voice signal fragments, estimation merges The Gauss model of voice signal fragment afterwards, and go to S104b and continue executing with；Otherwise, cluster is completed.

Similitude between voice signal fragment except Generalized Likelihood Ratio distance can be utilized to calculate, can also utilize pair Divergence algorithm is claimed to calculate.

Species multimedia information lib for carrying out cluster operation, the information bank is saved into when there is new source acoustical signal When, quick clustering is carried out, i.e.,：Using the set of all voice signals corresponding to each animal individual in existing cluster result as one Individual cluster initial input, while using each new source acoustical signal as a cluster initial input, clustered.

Species multimedia information lib for carrying out cluster operation, the information bank is saved into when there is new source acoustical signal When, it can also proceed as follows：By existing all voice signals in the information bank with new source acoustical signal together as cluster Initial input, clustered.

Species multimedia information lib for carrying out cluster operation, the information bank is saved into when there is new source acoustical signal When, it can also proceed as follows：Based on existing all voice signals in the information bank, action is entered to the new source acoustical signal Thing individual identification., will if the new source acoustical signal is recognized as belonging to some existing animal individual in the information bank " affiliated animal individual " information of the new affiliated project of source acoustical signal is designated as the mark of the animal individual；It is if described new Source acoustical signal is recognized as being not belonging to any existing animal individual in the information bank, then creates a new animal individual mark Note, and " affiliated animal individual " information of the new affiliated project of source acoustical signal is designated as the mark.

When the source acoustical signal preserved in the multimedia information lib to species word bank clusters, it can also impose a condition, Such as only when the active acoustical signal total amount of institute of preservation reaches predetermined threshold value, then carry out cluster operation.

The first voiceprint in the present embodiment is used in the voiceprint storehouse in source acoustical signal and each species word bank Sound-groove model is matched, and the second voiceprint is used to enter the source acoustical signal in the multimedia information lib in each species word bank Row cluster, because it is used for different scenes, the first voiceprint is applied to the differentiation of species, and the second voiceprint is then used for same Differentiation between one species Different Individual, therefore its first voiceprint and the second voiceprint are probably different parameters, when So, it is also possible to which identical parameter, this does not have strict restriction, as long as selected parameter can reach required effect i.e. Can.
