It is to be understood that such terms are interchangeable under appropriate circumstances such that the embodiments described herein are capable of operation in other sequences than those illustrated or otherwise described herein.
The embodiment of the application provides a rope skipping counting method, which is applied to intelligent wearing equipment, and the intelligent wearing equipment related to the embodiment of the application is portable equipment which is directly worn on or integrated with clothes or accessories of a user, and can include, but is not limited to, intelligent watches, intelligent wrist bands, intelligent glasses, rings or helmets and the like. For convenience of explanation, a smart watch will be described in detail below as an example. Referring to fig. 1, an overview flow of the rope skipping counting method provided in the embodiment of the present application is as follows:
step 101: and acquiring a rope skipping motion signal of the user.
In practical application, after a user enters a rope skipping mode by clicking a corresponding position in an interface of the intelligent watch or pressing a key, an accelerometer sensor or a gyroscope sensor arranged on the intelligent watch detects and obtains a rope skipping motion signal of the user. The rope skipping motion signal is a rope skipping motion signal detected by an accelerometer sensor or a rope skipping motion signal detected by a gyroscope sensor, wherein the rope skipping motion signal comprises three axial rope skipping motion signals of an x axis, a y axis and a z axis.
Step 102: and judging the change characteristics of the rope skipping motion signals in the first time, if the change characteristics meet the jump threshold conditions of the level of the user in the grading jump threshold conditions, determining that the user starts rope skipping, and calculating the first rope skipping number of the user in the first time.
In practical application, the hierarchical threshold conditions comprise different levels of threshold conditions of signal characteristics generated according to different degrees of force. The hierarchical threshold conditions may be generally divided into five levels, with the threshold conditions in each level being derived through large sample machine learning training. The rope skipping gesture and the force applying degree of different users are different, the signal characteristics generated by the force applying degree of the users can determine the level of the jump threshold condition corresponding to the signal characteristics generated by the force applying degree of the users in the hierarchical jump threshold condition, and whether the change characteristics of the rope skipping motion signal in the first time meet the jump threshold condition is judged; if yes, determining the user to take off, and recording the first rope skipping number of the user in the first time. If not, determining that the user does not take off. The condition of the grading jump threshold is mainly divided into two types, one is to set a grading jump threshold comprising a grading amplitude threshold and a grading interval threshold for the jump rope motion signal detected by the accelerometer sensor, and the other is to set a grading jump threshold comprising a grading amplitude threshold for the jump rope motion signal detected by the gyroscope sensor. By setting different levels of jump threshold conditions which are divided according to signal characteristics generated by different force-generating degrees in the grading jump threshold conditions, all jump threshold conditions corresponding to the signal characteristics generated by different force-generating degrees generated by different rope-skipping postures of different people can be covered, and the accuracy of rope-skipping starting accuracy and the accuracy of rope-skipping starting counting in the process of detecting different people are ensured.
In specific implementation, referring to fig. 2, determining a change feature of the rope skipping motion signal in the first time, if the change feature meets a jump threshold condition of a level where a user is located in a hierarchical jump threshold condition, determining that the user starts rope skipping and calculating the number of first rope skipping of the user in the first time may be, but is not limited to, the following ways:
step 201: and determining the jump threshold condition of the level of the user in the hierarchical jump threshold condition according to the signal characteristics generated by the stress degree of the user.
In practical application, the signal characteristics generated by the force degree of the user are detected by the intelligent watch in the process of the first rope skipping of the user. Specifically, when the user jumps the rope for the first time, the jump threshold value of the user is set smaller, and the intelligent watch can determine the signal characteristics generated by the stress degree of the user according to the jump rope motion signal of the user. The signal characteristics generated by the force exertion degree of the user can be obtained by, but not limited to, moving the sliding window according to a preset step length in a preset time, and comprehensively judging according to each peak value and each trough value in a preset number of sliding windows, wherein specific comprehensive judging modes include, but not limited to, that the amplitude of each peak needs to be larger than a smaller peak threshold value set for the first rope skipping of the user, and the amplitude of each trough needs to be smaller than a smaller trough threshold value set for the first rope skipping of the user. The classification threshold type may be preset according to a sensor generating the rope-skipping motion signal of the user, or the classification threshold type may be determined by a sensor recognizing the rope-skipping motion signal of the user, and then the class threshold condition corresponding to the user may be determined among the classification threshold conditions according to the signal characteristics generated by the degree of the user's stress.
Step 202: and determining the change characteristics of the rope skipping motion signals in the axial directions through the sliding window in the first time.
In practical application, each axial direction of the rope skipping motion signal mainly comprises three axial directions of an x axis, a y axis and a z axis. The sensors for detecting the obtained rope skipping motion signals are different, and the corresponding rope skipping motion signals are different in change characteristics. The change characteristics corresponding to the rope skipping motion signals detected and obtained by the accelerometer sensor are amplitude characteristics and interval characteristics, and the change characteristics corresponding to the rope skipping motion signals detected and obtained by the gyroscope sensor are amplitude characteristics. The window size of the sliding window is related to the frequency of the rope skipping motion signal, and referring specifically to fig. 3, the window size of the sliding window is smaller than one period of the rope skipping motion signal, and only one peak value and one trough value exist in each axial rope skipping motion signal in one sliding window. In the first time, a step length can be set, the sliding window is moved according to the step length, and the peak value and the trough value of each axial rope-skipping motion signal can be determined in the sliding window at each position and are correspondingly used as the amplitude characteristics of each axial rope-skipping motion signal in the sliding window at each position; and determining the time interval of two adjacent wave crests corresponding to each axial rope-skipping motion signal in the sliding window at the adjacent position, thereby obtaining the interval characteristic of each axial rope-skipping motion signal.
Step 203: if the change characteristic of one axial rope skipping motion signal meets the jump threshold condition, recording the rope skipping number of the first axial rope skipping motion signal, and taking the rope skipping number of the first axial rope skipping motion signal as the first primary selection rope skipping number.
In practical application, the first axial direction is the first axial direction in which the change characteristic of the rope skipping motion signal meets the jump threshold condition, and may be any axial direction in which any one of the three axial directions of the x axis, the y axis and the z axis included in the rope skipping motion signal meets the jump threshold condition at first. In the first time, aiming at the rope skipping motion signals obtained by the detection of the accelerometer sensor, if the amplitude characteristics and the interval characteristics in the sliding windows with the continuously preset quantity in one axial rope skipping motion signal meet the starting threshold value conditions of the level corresponding to the signal characteristics generated by the stress degree of the user, the number of the rope skipping of the first axial rope skipping motion signal is recorded as the number of the first initially selected rope skipping. In the first time, if the amplitude characteristics in the sliding windows with the continuously preset quantity in one axial rope skipping motion signal meet the jump threshold value condition of the level corresponding to the signal characteristics generated by the stress degree of the user in the rope skipping motion signal obtained through detection of the gyroscope sensor, the number of the rope skipping of the first axial rope skipping motion signal is recorded as the number of the first initially selected rope skipping. The amplitude characteristic refers to the peak value and the trough value of the rope-skipping motion signal in the same axial direction, and the interval characteristic refers to the interval between two adjacent peaks of the rope-skipping motion signal in the same axial direction or the interval between two adjacent troughs of the rope-skipping motion signal in the same axial direction. The number of the rope skipping of the first axial rope skipping motion signal is determined according to the amplitude characteristics of the first axial rope skipping motion signal, which meet the jump threshold condition of the level corresponding to the signal characteristics generated by the force exertion degree of the user.
Step 204: and if the change characteristics of at least two axial rope skipping motion signals meet the jump threshold value condition, taking the number of the second axial rope skipping motion signals as the second primary selection rope skipping number.
In practical applications, the second axis is the second axis in which the characteristic of the change in the rope-jump motion signal satisfies the jump threshold condition. The first time refers to the time consumed between the time when the change characteristics of the rope skipping motion signals of the first axial direction and the second axial direction after the rope skipping motion signals of the user are obtained and the time when the change characteristics of the rope skipping motion signals of the first axial direction and the second axial direction meet the take-off threshold conditions of the level where the user is located. Since the rope skipping action has a force in at least two axial directions, after determining that the change characteristics of the rope skipping motion signal in the first axial direction all meet the jump threshold condition of the level corresponding to the signal characteristics generated by the force degree of the user, when the rope skipping motion signal in the second axial direction also meets the jump threshold condition met by the change characteristics of the rope skipping motion signal in the first axial direction in the first time, the user can be determined to start rope skipping, and further, the specific number of ropes skipping of the rope skipping motion signal in the second axial direction may be determined as follows:
first case: the change characteristic of the second axial rope-skipping motion signal meets the corresponding take-off threshold condition, and the change characteristic of the third axial rope-skipping motion signal does not meet the corresponding take-off threshold condition. At this time, it is determined that the user starts rope skipping, and it is determined based on the number of amplitude features in the second rope skipping motion signal that satisfy the take-off threshold condition of the level corresponding to the signal feature generated by the user's degree of exertion.
Second case: the change characteristics of the rope skipping motion signals in the second axial direction and the third axial direction meet the corresponding take-off threshold conditions. At this time, it is determined that the user starts rope skipping, and the number of amplitude features satisfying the jump threshold condition of the level corresponding to the signal feature generated by the user's degree of force in the second rope skipping motion signal or the third rope skipping motion signal is determined as the second initially selected number of rope skipping, wherein the third axial direction is an axial direction other than the first axial direction and the second axial direction in the rope skipping motion signal.
Step 205: and determining the first rope skipping number in the first time according to the first primary selection rope skipping number and the second primary selection rope skipping number.
In practical application, there may be deviation between the first primary rope skipping number and the second primary rope skipping number, and the first rope skipping number in the first time needs to be further determined through the difference between the first primary rope skipping number and the second primary rope skipping number, which specifically can be but is not limited to the following modes:
judging whether the difference value between the first primary selection rope skipping number and the second primary selection rope skipping number is larger than a preset threshold value;
if yes, taking the minimum primary selection rope skipping number in the first primary selection rope skipping number and the second primary selection rope skipping number as the first rope skipping number;
if not, the largest primary selection rope skipping number in the first primary selection rope skipping number and the second primary selection rope skipping number is used as the first rope skipping number.
When the method is implemented, if the difference value between the first primary rope skipping number and the second primary rope skipping number is larger than a preset threshold value, the counting point representing the beginning corresponding to the axial direction corresponding to the larger primary rope skipping number in the first primary rope skipping number and the second primary rope skipping number is a non-rope skipping point, the counting point representing the beginning corresponding to the axial direction corresponding to the smaller primary rope skipping number in the first primary rope skipping number and the second primary rope skipping number is a real rope skipping starting point, and at the moment, the smallest primary rope skipping number in the first primary rope skipping number and the second primary rope skipping number is taken as the first rope skipping number. If the difference value of the first primary selection rope skipping number and the second primary selection rope skipping number is not larger than the preset threshold value, the largest primary selection rope skipping number in the first primary selection rope skipping number and the second primary selection rope skipping number is used as the first rope skipping number more accurately.
Step 103: and determining the rope skipping motion signal of the effective shaft in the rope skipping motion signals of the user as a target rope skipping motion signal.
In practical application, in order to reduce the operand of the identification process of rope skipping counting and reduce the interference caused by waveform abnormality in a certain axial direction, one axial rope skipping motion signal with normal overall waveform and larger waveform amplitude can be selected from the rope skipping motion signals of a user as a target rope skipping motion signal for further rope skipping counting identification. The waveform is normal, namely the condition that the same axial rope skipping motion signal in one window does not have secondary wave peaks, namely the condition of two wave peaks which are larger than each other.
Step 104: based on the amplitude of the effective waveform of the target rope-skipping motion signal after the first time, updating the counting threshold in real time, and sequentially identifying the waveform of the target rope-skipping motion signal after the first time according to the counting threshold to obtain the second rope-skipping number of the user after the first time.
In practical application, after determining that the user starts rope skipping, the waveform of the target rope skipping motion signal after the first time can be identified based on the counting threshold updated in real time, and specifically, the following modes can be adopted but are not limited to:
firstly, determining an initial counting threshold value based on the amplitude value of a target rope-skipping motion signal in the first time, and judging whether a first waveform of the target rope-skipping motion signal after the first time is an effective waveform or not according to the initial counting threshold value; if yes, recording the number of the second rope skipping and adding 1, and eliminating the number of the non-rope skipping; if not, the number of non-jump ropes is recorded plus 1.
In specific implementation, the initial counting threshold includes an initial peak counting threshold and an initial trough counting threshold, the initial peak counting threshold can be determined according to the average value of peak values meeting the threshold condition of the user's level in the first time multiplied by a mean value ratio coefficient, the initial trough counting threshold can be determined according to the average value of trough values meeting the threshold condition of the user's level in the first time multiplied by a mean value ratio coefficient, and the mean value ratio coefficient is generally selected to be 0.7. Judging whether a first waveform of the target rope-skipping motion signal after the first time is an effective waveform or not according to the initial counting threshold, if the peak of the first waveform is larger than the initial peak counting threshold and the trough of the first waveform is smaller than the initial trough counting threshold, recording the number of second rope-skipping and adding 1 if the first waveform is the effective waveform, and clearing the number of non-rope-skipping; otherwise, the first waveform is not a valid waveform, and the number of non-jump ropes is recorded plus 1.
Then, for each waveform after the first time of the target rope-skipping motion signal, determining a counting threshold of the current waveform based on the amplitude of the previous effective waveform and the counting threshold of the previous effective waveform; judging whether the current waveform in the target rope-skipping motion signal is a valid waveform or not according to the counting threshold value of the current waveform; if yes, recording the number of the second rope skipping and adding 1, and eliminating the number of the non-rope skipping; if not, the number of non-jump ropes is recorded plus 1.
In specific implementation, determining the count threshold of the current waveform based on the amplitude of the previous valid waveform and the count threshold of the previous valid waveform is specifically: count threshold of current waveform = count threshold of previous active waveform x a + amplitude of previous active waveform x b; where a is the proportionality coefficient of the count threshold of the previous active waveform, b is the proportionality coefficient of the amplitude of the previous active waveform, and a and b are empirically set. In the specific calculation process, substituting the wave crest counting threshold value of the previous effective waveform and the wave crest amplitude value of the previous effective waveform to obtain the current wave crest counting threshold value; substituting the trough counting threshold value of the previous effective waveform and the trough amplitude value of the previous effective waveform to obtain the current trough counting threshold value. Referring to fig. 4, whether the peak value of the current waveform in the target rope-skipping motion signal is greater than the count threshold of the peak of the current waveform and whether the valley value of the current waveform is less than the count threshold of the valley of the current waveform is determined according to the count threshold of the current peak and the count threshold of the current valley; if the crest value of the current waveform is larger than the counting threshold value of the current crest and the trough value of the current waveform is smaller than the counting threshold value of the current trough, the crest of the current waveform is an effective crest and the trough of the current waveform is an effective trough, the current waveform can be further determined to be an effective waveform, the number of second rope skipping is recorded, 1 is added, and the number of non-rope skipping is cleared; otherwise, determining that the current waveform is not the effective waveform, and recording the number of non-jump ropes plus 1. Therefore, the counting threshold value of the current waveform is determined based on the amplitude value of the previous effective waveform and the counting threshold value of the previous effective waveform, so that the dynamic adjustment of the counting threshold value can be realized, the adaptability of rope skipping counting is improved, and the counting accuracy is effectively improved.
Step 105: and determining the current total number of the rope skipping of the user based on the first rope skipping number and the second rope skipping number, and outputting the current total number of the rope skipping.
In the specific implementation, the sum of the number of the first rope skipping and the number of the second rope skipping is the current total number of the rope skipping of the user.
In one possible implementation manner, after obtaining the second rope skipping number of the user after the first time, it may also be determined whether the user stops rope skipping, specifically, but not limited to the following manners may be adopted:
judging whether the number of the non-skipping ropes is larger than a stop threshold value or not;
if yes, determining that the user stops rope skipping currently, recording the number of tripping ropes and adding 1, and outputting the sum of the number of the first rope skipping and the number of the current second rope skipping as the current continuous rope skipping number;
if not, determining that the user continuously jumps the rope currently.
In practical application, whether the user stops rope skipping can be determined according to whether the number of non-rope skipping is larger than a stop threshold value. If the number of the non-skipping ropes is larger than the stop threshold value, determining that the user stops skipping the ropes currently, wherein the stopping of skipping the ropes in the middle refers to stopping of skipping the ropes by the user due to the tripping of the ropes, at the moment, recording the tripping times, adding 1, updating the displayed tripping times, outputting the sum of the first skipping number and the current second skipping number as the current continuous skipping number, and if the number of the non-skipping ropes is not larger than the stop threshold value, determining that the user continuously skipping the ropes currently.
In one possible implementation manner, after determining the current number of continuous hops, the current maximum number of continuous hops of the user can be output, which can be specifically but not limited to the following ways:
when the current continuous hop number is determined to be greater than the historical maximum continuous hop number, the current continuous hop number is used as the maximum continuous hop number to be output.
In practical application, the intelligent watch can display the maximum continuous jump number of the user in real time, after the user stops the rope skipping due to the tripping rope and outputs the current continuous jump number each time, the current continuous jump number is compared with the historical maximum continuous jump number, if the current continuous jump number is larger than the historical maximum continuous jump number, the current continuous jump number is output as the maximum continuous jump number, and if the current continuous jump number is not larger than the historical maximum continuous jump number, the original maximum continuous jump number is maintained.
