First embodiment
Referring to fig. 2, fig. 2 is a flowchart of a step counting method according to a first embodiment of the present invention, as shown in fig. 2, the step counting method specifically includes the following steps:
step S100: when the current stage is in the starting stage, whether the current quantity value of the first invalid action of the invalid action characteristic in the first preset time exceeds a first threshold value is judged, and if not, the step S200 is executed.
And before judging whether the current quantity value of the first invalid action of the invalid action characteristics in the first preset time exceeds a first threshold value, acquiring action data of user action and extracting effective motion characteristics and invalid motion characteristics from the action data. The normal human step frequency is between 1 hz and 5 hz, i.e. the step interval is between 0.2 s and 1 s, but some human arm swings and steps are not in agreement, which results in a sinusoidal waveform in one axis of the sensor representing two steps, so the step interval should be between 0.2 s and 2 s, based on which the sampling frequency of the motion sensor (e.g. 25 hz) for acquiring the user's motion is determined, and the motion data needs to be slide-filtered to remove noise in the waveform before extracting the valid and invalid motion features from the motion data.
The body generates a periodically varying acceleration in the vertical direction when the person walks and also a periodically varying acceleration in the direction of travel due to the hand swinging motion during walking of the user, wherein the periodic variation resembles a sinusoidal waveform variation. The absolute value of the difference between the peak value and the valley value of the sine wave is the amplitude, and the time difference between the two sine wave peak values is the step interval, namely the time elapsed for generating a new step. Therefore, as an embodiment, in the motion data in this embodiment, the waveform with the step interval between 0.2 second and 2 seconds and the amplitude of 0.16g or more is the valid step feature, and the other waveforms are the invalid step features.
In most of the existing step counting methods, an accelerometer is used for collecting an acceleration value of a user movement, the difference between a wave crest and a wave trough of a waveform of the acceleration value is compared with a preset threshold value, and whether step counting is carried out or not is judged according to a comparison result. The step counting method only screens out effective step waveforms, judges whether a user is in a starting stage or a step counting stage according to the effective step waveforms, and counts steps by converting the effective step waveforms into step numbers, interference clutter may be generated by hand motions, bouncing motions and the like of the user during motion, and the interference clutter may be misjudged as the effective step waveforms, so that step counting errors are caused. To solve this problem, in the present embodiment, in addition to the valid motion feature, an invalid motion feature is extracted from the motion data, and whether to proceed to the next determination according to the valid motion feature is determined based on the invalid motion feature.
The first preset time may be adjusted according to actual needs and usage habits of a user, and optionally, the first preset time in this embodiment may be set to any value within one to five seconds.
The first current number value of the invalid actions is the sum of the numbers of the invalid action characteristics in the first preset time. Meanwhile, the first threshold may be adjusted according to different motion scenarios or motion habits of different users, and as an implementation manner, the first threshold in this embodiment may be set to any value between 5 and 12.
In addition, when the current number value of the first ineffective action of the ineffective action characteristic in the first preset time exceeds a first threshold value, the user is considered not to move at steps in the stage, the current stage is controlled to be kept in the starting stage, and the current number value of the first effective action is reset to zero.
Step S200: and judging whether the current quantity value of the first effective action of the effective action characteristic in the first preset time exceeds a second threshold value, and if so, executing the step S300.
The first effective motion current quantity value is the sum of the quantities of the effective motion characteristics in the first preset time. Meanwhile, the second threshold may also be adjusted according to different motion scenarios or motion habits of different users, and as an implementation manner, the first threshold in this embodiment may be set to any value between 5 and 15.
In addition, when the first effective action current quantity value of the effective action characteristics in the first preset time does not exceed the second threshold value, the user is considered not to enter a traveling state, the current stage is controlled to be kept in the starting stage, and the first effective action current quantity value is updated based on the new effective action characteristics obtained in the first preset time.
As an embodiment, when the current first effective motion quantity value of the effective motion feature within the first preset time exceeds a second threshold, the similarity determination of the effective motion feature is further required. Because the steps generated when the user travels are continuous and have certain similarity, whether the effective step characteristics are generated by interference or not can be judged according to the similarity of the steps, the similarity judgment can be that the difference of the step intervals between every two effective step characteristics is less than 250 milliseconds or the difference of the amplitudes between every two effective step characteristics is less than 0.16g, and in addition, the similarity judgment can be carried out on the step intervals and the amplitudes by using other mathematical methods such as standard deviation and the like respectively, which is not listed in the invention.
Step S300: and controlling the current stage to enter a step counting stage, and counting steps according to the current numerical value of the first effective action.
And after controlling the current stage to enter a step counting stage, converting the current value of the first effective action into a first new step increasing number, and counting the first new step increasing number into the total step number. And converting a second effective action current quantity value of the effective action characteristics which is newly acquired in a second preset time of the step counting stage into a second new step number increasing step number, and counting the second new step number increasing step number into a total step number. As an implementation manner, the second preset time may be adjusted according to specific needs, and in this embodiment, the second preset time is 2 seconds.
When the step conversion is performed, such as converting the current magnitude of the first effective action into the first new increment step, the step waveform can be considered to represent two steps when the magnitude is greater than 0.78g and the step interval is greater than 450 ms, the step can be considered to represent two steps when the magnitude is greater than 0.16g and the step interval is greater than 1 s, and the effective step waveforms in other cases are considered to be one step.
Referring to fig. 3, fig. 3 is a logic diagram of a decision for switching the current stage according to a first embodiment of the present invention.
As an embodiment, in the second preset time, it is further determined whether to acquire an effective action feature within the second preset time. If yes, controlling the current stage to be kept in the step counting stage; and if not, determining that the user stops moving the step, and controlling the current stage to enter the starting stage again.
Further, after the starting stage is entered again, whether a third effective action current quantity value of the effective action characteristics in a third preset time exceeds a second threshold value is judged. If so, determining that misjudgment occurs, multiplying the frequency of the effective action characteristic in the second preset time and the length of the third preset time to obtain a third effective action current number value, converting the third effective action current number value into a third new step number, counting the third new step number into the total step number, and controlling the current stage to enter the step counting stage again to count steps.
It should be noted that, in the step counting stage, it may also be that other motions, such as arm swing and jumping, of the user cause erroneous recognition, and recognize other motion features as the valid motion features, so that in the step counting stage, it is determined whether a second invalid motion current number value of the invalid motion features within a fourth preset time exceeds a third threshold, and if so, the current stage is controlled to enter the starting stage, and the first new increment number is cleared.
It should be understood that the acceleration value of the user's movement is collected by the accelerometer, and in the present embodiment, the collected acceleration value can be decomposed into acceleration values in three coordinate axis directions perpendicular to each other, x, y, and z. When the series of judgment is carried out, valid step waveforms and invalid step waveforms acquired by the x, y and z step counting axes are acquired and analyzed in sequence, and after all the step counting axes are analyzed, the current stage is judged to be switched. For example, in the second preset time, whether effective action characteristics in the second preset time are acquired is judged, and if yes, the current stage is controlled to be kept in the step counting stage; if not, judging whether the average copy of the effective action characteristics obtained by the detection of other step counting shafts exceeds a preset threshold value, selecting the step counting shaft with better signal quality, namely the step counting shaft with larger average amplitude of the effective action characteristics, as a new main step counting shaft, and exiting the step counting stage when the average amplitude of the effective action characteristics of other step counting shafts does not exceed the preset threshold value. For example, when the current main step counting axis is an x step counting axis and no effective action feature is collected by the x step counting axis in a preset time window, whether average amplitudes of the effective action features collected by the y step counting axis and the z step counting axis exceed a preset threshold value is judged: when the average amplitude of the effective action characteristics acquired by the y step counting shaft and the z step counting shaft does not exceed a preset threshold value, switching the current stage to a starting stage; when the average amplitude of the effective action characteristics acquired by one of the y step counting shaft or the z step counting shaft exceeds a preset threshold value, assuming that the average amplitude is the y step counting shaft, selecting the y step counting shaft as a new main step counting shaft, keeping the current stage as a step counting stage, converting the number of the effective action characteristics of the y step counting shaft in a preset window time into a new step number, and counting the new step number into a total step number; when the average amplitude of the effective action characteristics acquired by the y step counting axis and the z step counting axis exceeds a preset threshold, judging which step counting axis has larger average amplitude of the effective action characteristics, assuming that the average amplitude of the effective action characteristics of the y step counting axis is larger, selecting the y step counting axis as a new main step counting axis, keeping the current stage as a step counting stage, converting the number of the effective action characteristics of the y step counting axis in a preset window time into a new step number, and counting the total step number.
In the step counting method provided in the first embodiment of the present invention, when the current stage is in the starting stage, it is determined whether a first invalid motion current quantity value of an invalid motion feature within a first preset time exceeds a first threshold, and if not, it is determined whether a first valid motion current quantity value of an valid motion feature within the first preset time exceeds a second threshold, and when the first valid motion current quantity value exceeds the second threshold, the current stage is controlled to enter the step counting stage, and step counting is performed according to the first valid motion current quantity value. And after controlling the current stage to enter a step counting stage, judging whether effective action characteristics within second preset time are obtained or not within second preset time, if not, re-entering the starting stage, and after the step counting stage detects that the effective action characteristics are misjudged, performing step number compensation and re-entering the step counting stage. The step counting method provided by the embodiment accurately converts the effective action characteristics and the ineffective action characteristics of the user in the starting stage and the step counting stage by simultaneously acquiring and according to the effective action characteristics and the ineffective action characteristics of the user, and simultaneously avoids misjudgment and wrong step counting caused by the misjudgment compensation by analyzing the current quantity value of the ineffective action characteristics and the step number compensation.
