Specific embodiment

With reference to the accompanying drawings and examples, the specific embodiment of the application is described in further detail.Implement below Example is not limited to scope of the present application for illustrating the application.

It will be appreciated by those skilled in the art that the size of the serial number of following each steps is not intended in embodiments herein Execution sequence it is successive, the execution of each step sequence should be determined by its function and internal logic, and implement without coping with the application The implementation process of example constitutes any restriction.

Inventor has found in the course of the research, will receive gravity since blood flows in the body, leads to user's body In different positions, internal flow speed can change at some positions of body.By taking arm as an example, in the state of hanging down and height Act state, internal flow speed are significantly different.This is because arm is in when holding state high, compared to the posture that hangs down, blood is needed Finger can just be flowed to by overcoming gravity to do more function, so that blood flow velocity can be reduced.Based on the principle, the application can be real Now to the information input of electronic equipment.

Fig. 1 is the flow chart that input information determines method described in the application one embodiment, and the method can be for example One input information determines to be realized in equipment.As shown in Figure 1, which comprises

S120: one first is obtained in the reference site of user and refers to blood flow information；

S140: a first object blood flow information is obtained in the target site of the user；

S160: determine described first with reference to one first reference point in blood flow information with it is right in the first object blood flow information Answer the first time between a first object point of first reference point poor；

S180: information is inputted according at least to the first time poor determination one first.

The embodiment of the present application the method obtains one first in the reference site of user and refers to blood flow information, described The target site of user obtains a first object blood flow information, then determines that described first joins with reference in blood flow information one first The first time corresponded between a first object point of first reference point in examination point and the first object blood flow information is poor, And then information is inputted according at least to the first time poor determination one first.To provide it is a kind of determined based on blood flow information it is defeated The method for entering information is conducive to the input capability for enhancing wearable device.

Below with reference to specific embodiment, the function of described step S120, S140, S160 and S180 is described in detail.

S120: one first is obtained in the reference site of user and refers to blood flow information.

Wherein, the reference site generally can be the stabilization position on the user's body, i.e. less physical activities or movement Amplitude lesser position, such as the ear, the bridge of the nose, the forehead that can be user etc..

Blood flow information described herein can such as be PPG (PhotoPlethysmoGraphy, photoelectricity volume pulsation Wave) information or Doppler measurement information, it can be acquired and be obtained by corresponding sensor, for example can sensed by PPG Device acquisition obtains the PPG information.Described first with reference to the blood flow information that blood flow information is in reference position acquisition.

S140: a first object blood flow information is obtained in the target site of the user.

Wherein, the target site is the position of any one posture to be detected on the user's body, for example can be use Arm, the leg at family etc..

As it was noted above, the blood flow information can such as be PPG information or Doppler measurement information, first mesh Mark blood flow information is the blood flow information in target site acquisition.

It will be to be illustrated in the case where PPG information or Doppler measurement information respectively to the blood flow information below.

A), in one embodiment, the blood flow information is PPG information, and the corresponding step S160 is further are as follows:

S160a: determine described first with reference to one first reference point in PPG information with it is right in the first object PPG information Answer the first time between a first object point of first reference point poor.

In one embodiment, referring to fig. 2, the step S160a may include:

S161a: the corresponding temporal information of first reference point is determined；

S162a: the corresponding temporal information of the first object point is determined；

S163a: according to the corresponding temporal information of first reference point and the corresponding temporal information of first object point Determine that the first time is poor.

In the step S161a, first reference point can be any wave crest, the trough with reference in PPG information, Or it is also possible to other characteristic points, for example " electronics and encapsulation " the 4th phase of volume 12 " is based on FPGA photoplethysmographic The IP core design of parameter detecting " Fig. 1 is mentioned in a text starting point, weight peak etc., herein described wave crest can correspond in this article Fig. 1 Main peak.The corresponding temporal information of first reference point can be determined according to the acquisition time with reference to PPG information.

In the step S162a, the first object point is opposite with first reference point in the target PPG information The characteristic point answered, such as in the case where first reference point is the wave crest with reference in PPG information, described first Target point is the wave crest in the target PPG information.The corresponding temporal information of the first object point can be according to the mesh The acquisition time for marking PPG information determines.

Fig. 3 is the comparison of wave shape schematic diagram with reference to PPG information and the target PPG information.The reality of waveform shown in Fig. 3 Testing scene can be with as shown in figure 4, the reference site is ear's such as ear-lobe 410 of user, the target site be user's Hand such as finger 420, the hand gestures of user under arm as shown in figure 4, stretch.

As shown in figure 3, first reference point is the wave crest with reference in PPG information, i.e. the first curve in Fig. 3 C1 point on 310, the first object point is another wave crest corresponding with C1 in the target PPG information, i.e. second in Fig. 3 D1 point on curve 320.

Corresponding 2346th sampled point of C1 as can see from Figure 3, corresponding 2358th sampled point of D1, every two sampled point Between time interval be 5ms, then the time interval between C1 and D1 be 60ms, thus the first time it is poor be 60ms.? That is the sensor ratio when arm is in down and stretches posture, for the PPG signal of the same cardiac cycle, in ear-lobe position Wave crest is detected in the sensor morning 60ms of finger position.

In addition, it will be appreciated by those skilled in the art that right in the first reference PPG information and the first object PPG information Answer the time interval between two wave crests of same cardiac cycle that should be less than the half of cardiac cycle.That is, described One is less than with reference to a wave crest in the wave crest and the first object PPG information in PPG information, only its time interval The half of cardiac cycle can be just to belong to the same cardiac cycle, and otherwise, the two is not belonging to the same cardiac cycle.Common people's Cardiac cycle is about 0.8 second, can be with measured in advance for each specific user.Accordingly, can believe in the first object PPG The wave crest for belonging to same cardiac cycle corresponding with a wave crest in the first reference PPG information is found in breath.Similar, It, can also be according to above-mentioned judgment method described the in the case where first reference point is other characteristic points in addition to wave crest The first object point corresponding with first reference point is found in one target PPG information.

In addition, first reference point and first object point belong to same cardiac cycle, it can simplify calculating and protect Demonstrate,prove higher gesture recognition accuracy.Meanwhile if first reference point and first object point be not belonging to it is same aroused in interest Herein described method still also may be implemented in period, for example first reference point is the wave crest of a cardiac cycle, described First object point is the wave crest of next cardiac cycle.Its realization principle has no difference, will hereafter continue to explain.

Fig. 5 is another comparison of wave shape schematic diagram with reference to PPG information and the target PPG information.Waveform shown in Fig. 5 Experiment scene can be with as shown in fig. 6, the reference site remains as the ear-lobe 410 of user, the target site remains as institute The finger 420 for stating user, unlike scene shown in Fig. 4, in the experiment, the hand gestures of user are hand arm held upward.

As shown in figure 5, first reference point answers a wave crest C2 point in the reference PPG information, the first object A wave crest D2 point in the corresponding target PPG information of point.

In fig. 5 it may be seen that C2 corresponds to the 5966th sampled point, corresponding 6010th sampled point of D2, between C2 and D2 Time interval be 220ms, thus the first time it is poor be 220ms.That is, when arm is in and holds posture high, it is right In the PPG signal of the same cardiac cycle, sensor in ear-lobe position is 220ms more early than the sensor in finger position to be detected Wave crest.

Comparison diagram 3 and Fig. 5 it can be found that two experiment in, what is uniquely changed is the posture of user's hand, i.e., arm by Under stretch variation to hold high, so as to cause the first time it is poor by 60ms variation be 220 seconds, the two differs by more than 3.5 times.This Exactly because holding high in posture when arm is in, internal blood is affected by gravity, and is in down when stretching posture compared to arm, stream Speed reduces；And ear position, due to relatively stable, without height change, blood flow velocity there is no variation.

B), in another embodiment, the blood flow information is Doppler measurement information, the Doppler measurement information It can such as be LDF (Laser Doppler Frequency, laser Doppler shift), LDV (Laser Doppler Velocimetry, Laser Doppler speed), supersonic Doppler frequency displacement etc. comprising a series of Envelop waves signal, to it The available corresponding frequency-region signal of such as Fast Fourier Transform (FFT) is carried out, the doppler-frequency component in the frequency-region signal is just Than in blood flow velocity, so as to obtain velocity of blood flow, the haemocyte that further includes according to blood flow velocity and blood cross section Quantity can determine blood flow flux.

The corresponding step S160 is further are as follows:

S160b: determine that described first is how general with reference to one first reference point in Doppler measurement information and the first object The first time strangled between the first object point for corresponding to first reference point in metrical information is poor.

In one embodiment, may include: referring to Fig. 7, the step S160b

S161b: the corresponding temporal information of first reference point is determined；

S162b: the corresponding temporal information of the first object point is determined；

S163b: according to the corresponding temporal information of first reference point and the corresponding temporal information of first object point Determine that the first time is poor.

In the step S161b, first reference point can correspond to the peak point of blood flow velocity, valley point or other Characteristic point.

In the step S162b, the first object point is point corresponding with first reference point, such as described One reference point be it is described with reference to the peak point of blood flow velocity is corresponded in Doppler measurement information when, the first object point can be The peak point of blood flow velocity is corresponded in the target Doppler metrical information.

First reference point and first object point belong to same cardiac cycle, can simplify calculating and guarantee higher Gesture recognition accuracy.Meanwhile if first reference point and first object point are not belonging to same cardiac cycle, still Herein described method so also may be implemented.

In the step S163b, the first time corresponding temporal information of poor i.e. first reference point and described the The difference of the corresponding temporal information of one target point, in the corresponding temporal information of first reference point and first object point pair In the case that the temporal information answered is known, it is poor can readily to obtain the first time.To how really stress below Determine the corresponding temporal information of first reference point and the corresponding temporal information of first object point.

In one embodiment, the step S161b may further include:

S1611b: one first reference flow rate relevant information is obtained with reference to Doppler measurement information according to described first；

S1612b: the corresponding temporal information of first reference point is determined according to the first reference flow rate relevant information.

In the step S1611b, what the first reference Doppler measurement information was namely obtained in the reference site Doppler measurement information.As it was noted above, according to the available blood flow velocity of the Doppler measurement information and blood flow flux, from And blood flow flux is referred to reference to blood flow velocity and first with reference to Doppler measurement information available first according to described first.Institute The data type for stating the first reference flow rate relevant information can be the blood flow velocity, is also possible to the blood flow flux, changes sentence It talks about, the first reference flow rate relevant information can be first and refer to blood flow flux with reference to blood flow velocity or first.

It is first with reference to the case where blood flow flux in the first reference flow rate relevant information in the step S1612b Under, waveform can be such as the first curve 310 in Fig. 3.First reference point can be wave crest in the waveform, trough or Other characteristic points, for example can be the wave crest C1 on the first curve 310.It, can in the case where determining first reference point To determine the corresponding temporal information of first reference point with reference to the corresponding temporal information of blood flow flux according to described first.It is described First reference flow rate relevant information is first similar with above situation with reference to the case where blood flow velocity, no longer independent explanation.

In one embodiment, the step S162b may include:

S1621b: a first object flow velocity relevant information is obtained according to the first object Doppler measurement information；

S1622b: the corresponding temporal information of the first object point is determined according to the first object flow velocity relevant information.

In the step S1621b, what the first object Doppler measurement information was namely obtained in the target site Doppler measurement information.Similar to the first reference flow rate relevant information, the data of the first object flow velocity relevant information Type is also possible to the blood flow velocity, or is also possible to the blood flow flux, in other words, the first object flow velocity phase Closing information can be first object blood flow velocity or first object blood flow flux.

In the step S1622b, the case where the first object flow velocity relevant information is first object blood flow flux Under, waveform can be such as the second curve 320 in Fig. 3.The first object point is corresponding with first reference point, such as First reference point is on the first curve 310 in the case where the wave crest C1, and the first object point can be the second curve Another wave crest D1 on 320.It, can be according to the first object blood flow flux pair in the case where determining the first object point The temporal information answered determines the corresponding temporal information of the first object point.The first object flow velocity relevant information is the first mesh The case where marking blood flow velocity is similar with above situation, no longer independent explanation.

Still shown in Fig. 3 for waveform, it can be seen that differ 12 sampled points, every two phase between wave crest C1 and wave crest D1 Time difference between adjacent sampled point is 5ms, and therefore, poor corresponding first time is 60ms.

It will be understood by those skilled in the art that being substantially first by Doppler measurement information (first in above embodiment With reference to Doppler measurement information and first object Doppler measurement information) be converted to flow velocity relevant information similar to PPG information (the first reference flow rate relevant information and first object flow velocity relevant information), then according to the processing mode of similar embodiment a) Determine that the first time is poor.

In another embodiment, described first can also be determined according to the corresponding frequency domain information of Doppler measurement information Time difference.Specifically, the step S161b may include:

S1611b ': according to scheduled duration, by described first, with reference to Doppler measurement information, how general be divided into multiple sub- references Strangle metrical information；

S1612b ': frequency domain conversion is carried out with reference to Doppler measurement information to the multiple son, how general obtains multiple sub- references Strangle measurement frequency domain information；

S1613b ': it is surveyed with reference at least one son determining in Doppler measurement frequency domain information with reference to Doppler in the multiple son Frequency domain information is measured, at least one son meets one first predetermined item with reference to the Doppler frequency shift amount of Doppler measurement frequency domain information Part；

S1614b ': determine that first reference point is answered with reference to Doppler measurement frequency domain information according at least one son Temporal information.

In the step S1611b ', actually to the first reference Doppler measurement information according to the pre- timing Long time window is divided.It can partially overlap between two neighboring time window or not be overlapped.When two neighboring Between in the case that window is not overlapped, the scheduled duration such as can be 5ms, 15ms or 20ms；In two neighboring time window segment In the case where coincidence, the scheduled duration can be longer, for example can be 50ms.

Referring to Fig. 8, it is described first with reference to Doppler measurement information waveform can as shown in the curve of the middle and upper part Fig. 8, according to Available t1-t5 as shown in the figure amounts to 5 sons with reference to Doppler measurement letter after the scheduled duration carries out the division without coincidence It ceases (wherein, t2, t3 are not shown).

It, can be such as by modes such as Fast Fourier Transform (FFT)s, to the multiple son with reference to more in the step S1612b ' General Le metrical information carries out frequency domain conversion, obtains multiple sons with reference to Doppler measurement frequency domain information.Referring to Fig. 8, when such as Fig. 4 institute Show, using the ear-lobe 410 of user as the reference site, when the hand of user stretches posture under being in, the obtained son is with reference to more Pu Le measures the waveform of frequency domain information as shown in lower curve in Fig. 8, it can be seen that every height refers to Doppler measurement information pair A son is answered to refer to the waveform of Doppler measurement frequency domain information, and different sons refers to the waveform of Doppler measurement frequency domain information Also different.It can be seen that from left to right, following variation tendency is presented with reference to the waveform of Doppler measurement frequency domain information in multiple sons: The height of wave heave part reduces, and the width of convex portion increases.The variation of above-mentioned waveform reflects multiple sub- references in fact The variation of the corresponding Doppler frequency shift amount of Doppler measurement frequency domain information, i.e., from left to right, Doppler frequency shift amount gradually increases.Its In, Δ f indicates that corresponding son refers to the corresponding Doppler frequency shift amount of Doppler measurement frequency domain information.

In the step S1613b ', at least one son is according to described the in fact with reference to Doppler measurement frequency domain information One predetermined condition is from the multiple son with reference to part filtered out in Doppler measurement frequency domain information with reference to Doppler measurement frequency Domain information.First predetermined condition such as can be at least one son with reference to Doppler's frequency of Doppler measurement frequency domain information Shifting amount is more than or equal to a first threshold, perhaps less than a second threshold or between certain two threshold value.With first threshold For value, the first threshold can be the Doppler frequency shift amount when peak value of corresponding blood flow velocity.Similar, other threshold values can To be the Doppler frequency shift amount of other characteristic points in corresponding such as PPG information.By taking Fig. 8 as an example, it is assumed that first predetermined condition It is more than or equal to f5 with reference to the Doppler frequency shift amount of Doppler measurement frequency domain information at least one son, due to f1, f2, f3, f4 Respectively less than f5, then the Doppler frequency shift amount of only t5 meets first predetermined condition.

It, can be according at least one son with reference to any of Doppler measurement frequency domain information in the step S1614b ' The corresponding time determines the corresponding temporal information of first reference point.By taking Fig. 8 as an example, since the scheduled duration is all shorter, So such as can by the beginning of t5, intermediate time or finish time be determined as the first reference point corresponding time Information.

It should be noted that in Fig. 8 it is described first with reference to Doppler measurement information be a cardiac cycle it is corresponding Part Doppler measurement information, so only having found one meets the son of first predetermined condition with reference to Doppler measurement frequency domain Information.In practical application, when the first reference Doppler measurement information is corresponding Doppler measurement letter of multiple cardiac cycles When breath, multiple sons for meeting first predetermined condition may be found with reference to Doppler measurement frequency domain information.In this case, The time of first reference point can be determined with reference to Doppler measurement frequency domain information according to the son that any one is found, such as can The time that Doppler measurement frequency domain information determines first reference point is referred to the son being found according to first.

Similar, in one embodiment, the step S162b may include:

S1621b ': it is how general that the first object Doppler measurement information is divided into multiple sub-goals according to scheduled duration Strangle metrical information；

S1622b ': frequency domain conversion is carried out to the multiple sub-goal Doppler measurement information, how general obtains multiple sub-goals Strangle measurement frequency domain information；

S1623b ': determine that an at least sub-goal Doppler surveys in the multiple sub-goal Doppler measurement frequency domain information Frequency domain information is measured, the Doppler frequency shift amount of an at least sub-goal Doppler measurement frequency domain information meets one first predetermined item Part；

S1624b ': determine that the first object point is corresponding according to an at least sub-goal Doppler measurement frequency domain information Temporal information.

The realization principle of the step S1621b ' is similar with the realization principle of the step S1611b ', actually pair The first object Doppler measurement information is divided according to the time window of the scheduled duration.Between two neighboring time window It can partially overlap or not be overlapped.In the case where two neighboring time window is not overlapped, the scheduled duration such as may be used Think 5ms, 15ms or 20ms；In the case where two neighboring time window partially overlaps, the scheduled duration can be longer, It for example can be 50ms.

Referring to Fig. 9, when as shown in figure 4, using the finger 420 of user as the target site, the hand of user is stretched under being in When posture, the waveform of the first object Doppler measurement information can be as shown in the curve of the middle and upper part Fig. 9, according to the pre- timing After long division of the progress without coincidence (wherein, available t1 '-t8 ' as shown in the figure amounts to 8 sub- target Doppler metrical informations T2 '-t6 ' is not shown).

The realization principle of the step S1622b ' can be similar with the realization principle of the step S1612b '.Specifically , the step S1622b ' can be such as by modes such as Fast Fourier Transform (FFT)s, to the multiple sub-goal Doppler measurement Information carries out frequency domain conversion, obtains multiple sub-goal Doppler measurement frequency domain informations.Referring to Fig. 9, the sub-goal Doppler is surveyed The waveform of frequency domain information is measured as shown in lower curve in Fig. 9, it can be seen that each sub-goal Doppler measurement information is one corresponding The waveform of sub-goal Doppler measurement frequency domain information, and the waveform of different sub-goal Doppler measurement frequency domain informations is not yet Together.It can be seen that from left to right, following variation tendency: waveform is presented in the waveform of multiple sub-goal Doppler measurement frequency domain informations The height of convex portion reduces, and the width of convex portion increases.How general the variation of above-mentioned waveform reflect multiple sub-goals in fact The variation of the corresponding Doppler frequency shift amount of measurement frequency domain information is strangled, i.e., from left to right, Doppler frequency shift amount gradually increases.Wherein, The corresponding Doppler frequency shift amount of the corresponding sub-goal Doppler measurement frequency domain information of Δ f expression in Fig. 9.

The realization principle of the step S1623b ' can be similar with the realization principle of the step S1613b '.Specifically , in the step S1623b ', an at least sub-goal Doppler measurement frequency domain information is predetermined according to described first in fact The part sub-goal Doppler measurement frequency domain information that condition is filtered out from the multiple sub-goal Doppler measurement frequency domain information. First predetermined condition can be with the first predetermined item for referring to Doppler measurement frequency domain information for screening at least one son Part is similar, for example can be the Doppler frequency shift amount of an at least sub-goal Doppler measurement frequency domain information and reach one first Threshold value, perhaps less than a second threshold or between certain two threshold value.By taking the first threshold as an example, first threshold Value can be the Doppler frequency shift amount when peak value of corresponding blood flow velocity.Similar, other threshold values can be corresponding such as PPG letter The Doppler frequency shift amount of other characteristic points in breath.By taking Fig. 9 as an example, it is assumed that first predetermined condition is an at least sub-goal The Doppler frequency shift amount of Doppler measurement frequency domain information is more than or equal to f5, and assumes only have f8 ' to be greater than f5, and f1 '-f7 ' is small In f5, then the Doppler frequency shift amount of only t8 ' meets first predetermined condition.

The realization principle of the step S1624b ' can be similar with the realization principle of the step S1614b '.Specifically , it, can be corresponding according to described at least any of sub-goal Doppler measurement frequency domain information in the step S1624b ' Time determines the corresponding temporal information of the first object point.By taking Fig. 9 as an example, such as can will be at the beginning of t8 ', when intermediate It carves or finish time is determined as the corresponding temporal information of the first object point.

It should be noted that the first object Doppler measurement information in Fig. 9 be a cardiac cycle it is corresponding Part Doppler measurement information, so only having found the sub-goal Doppler measurement frequency domain for meeting first predetermined condition Information.In practical application, when the first object Doppler measurement information is corresponding Doppler measurement letter of multiple cardiac cycles When breath, multiple sub-goal Doppler measurement frequency domain informations for meeting first predetermined condition may be found.In this case, The son that should be found according to predetermined policy according to some determines first reference point with reference to Doppler measurement frequency domain information Time, such as can be according to the sub-goal Doppler measurement being found belonged to first reference point in a cardiac cycle Frequency domain information determines the time of the first object point.It will be appreciated by those skilled in the art that the predetermined policy and the method exist The training data acquisition modes of training stage are corresponding.

In conjunction with Fig. 8 and Fig. 9, the length of time window is 20ms in two figures, and described first refers to Doppler measurement information It is identical with first object Doppler measurement information start time, then it can determine the time and described first of first reference point 3 time windows of time phase difference of target point, i.e. difference 60ms, i.e., the poor described first time is 60ms.That is, when with user Ear-lobe 410 be used as the reference site, finger 420 is obtained when user's hand stretches posture under being in as the target site The poor first time is 60ms, which matches with the experimental result in embodiment a).

In addition, inventor according to scene shown in Fig. 6, i.e. the ear-lobe 410 of a user is used as the reference site, finger 420 As the target site, user's hand is in obtain corresponding first respectively when holding posture high and refer to Doppler measurement information With first object Doppler measurement information, then to obtain the first time poor also close to 220ms for processing according to the method described above, i.e., It matches with the experimental result in embodiment a).

In the application the example above, when the first reference point corresponding time is corresponding earlier than the first object point Between, still, the implementation of herein described method is not required for the first reference point corresponding time earlier than the first object The point corresponding time.In other words, the first reference point corresponding time, it is corresponding can also to be later than the first object point Time.It for example can be that positive value or negative value distinguish above-mentioned two situations according to the first time poor value.

As it was noted above, in the case where the target site is in different postures, the obtained first time poor meeting There is apparent difference, is based on this, the target site of user shows different postures, can correspond to obtain different described first Time difference, and then determine different the first input information.

Therefore, in one embodiment, the step S120 may include:

S120 ': showing a prime in response to the target site of the user, obtains described the in the reference site One refers to PPG information, and the prime corresponds to the first input information.

That is, user can input different input information by the posture of the change target site to control.

Correspondingly, in one embodiment, the step S180 may include: referring to Figure 10

S181: according at least to one first posture of the first time poor determination target site；

S182: the first input information is determined according to first posture.

In the step S181, the first time corresponding relationship of poor and described first posture can be predefined, tool Body, it can train in advance and obtain look-up table as shown in Table 1.Wherein, described to indicate user in training stage phase with reference to posture Answer the posture of target site；The reference time difference is indicated in the case that described with reference to posture, what the reference site detected In the first object blood flow information that the time of the first reference point and the target site detect in first reference blood flow information Difference between the time of first object point, for example, it can be a certain feature in the PPG information that the reference site detects Time and the time of another feature point corresponding with the characteristic point in the PPG information that the target site detects of point it Between time difference.

By taking the first row record in table 1 as an example, reference time difference is to detect when stretching posture under the hand of user is in ear To PPG information in primary peak in the time difference in the PPG information that hand detects between corresponding secondary peak.The ginseng Examining the time difference can be obtained by multiple training experiment, be can be a time value and be also possible to time range as shown in Table 1.

In addition, the reference time difference in table 1 is to belong to a week aroused in interest based on the primary peak and the secondary peak What the phase determined, it will be appreciated by those skilled in the art that in the training stage primary peak and the secondary peak can also be based on not Belong to a cardiac cycle and determine that the reference time is poor, only the primary peak described in the training stage and second wave Peak whether belong to need same cardiac cycle and when the practical execution of the method described in the first reference point and first object point Selection it is consistent.For example, the primary peak described in the training stage and the secondary peak belong to same cardiac cycle, then in reality First reference point described in when border is applied and first object point will also belong to a cardiac cycle；Second described in the training stage Wave crest lags one cardiac cycle of primary peak, then in practical application, the first object point will also lag described first One cardiac cycle of reference point.
