In one embodiment of the invention, as shown in Figure 1, a kind of bearing calibration of step-length, including:
Step S1 will be calculated when getting physiological information input by user for the first time according to the physiological information
Obtained step-length is as step-length to be corrected;
Step S2 obtains the current of user's n-th running when not depositing step-length after calibration and specific running modes are opened

The current running of n-th is calculated according to the current step number of the step-length to be corrected and n-th in step S3
Distance;
Described in the current running distances, the practical running distance of n-th, n-th of the step S4 according to n-th
Current step number and the step-length to be corrected, are calculated the current average step length of n-th;
Step S5 is when the current average step length of n-th meets preset condition, then it is assumed that corrects successfully, and by N
The secondary current average step length is set as step-length after the correction.
Specifically, when user wants using movement APP, it can all require user's registration and fill in the physiology such as height, gender
A step-length can be calculated according to physiological information, using this as the initial value of step-length to be corrected in data information.
Specific running modes are primarily referred to as being multiplied by step number using step-length to calculate the pattern of running distance, such as:Indoor race
Step mode.
Step-length, user open specific running modes after there is no correction again when, user may require that after the completion of movement
The practical running distance of its running is inputted, subsequent correction is used for.Current step number refers to that user runs under specific running modes
Total step number, by be equipped with movement APP electronic device (such as:Wrist-watch, bracelet, mobile phone etc.) voluntarily statistics obtain.It is current to run
Step pitch is from referring to being multiplied with step-length to be corrected according to the current step number of statistics, by the running distance of electronic device oneself statistics.
In step-length after not corrected, opens after specific running modes are run, can all require user to input practical
Running distance, for the correction to step-length, until step-length after being corrected.User can after opening specific running modes,
Oneself total running plan is divided into repeatedly running to carry out, to quickly carry out the correction to step-length.Such as:Obtain it is to be corrected
After the initial value of step-length, first opens specific running modes, and specifically always running plan can run user to run 5000m
It when to 2000 meters, stops, electronic device is allowed to obtain current current step number, practical 2000 meters of progress of running distance input by user
Correction;Later, user has run 1000 meters again, and user stops running, and electronic device is allowed to obtain current current step number, user's input
1000 meters of practical running distance be corrected;Then, family has run 2000 meters again, and user stops running, and electronic device is allowed to obtain
Current current step number, practical 2000 meters of distance of running input by user are corrected.Therefore, as long as no step-length after correction,
And specific running modes, when opening, user runs in the case, specific n-th be according to the actual running situation of user and
Fixed, that is to say, that it is to be decided how to calculate primary running by user oneself.
If depositing step-length after calibration, user will not be required to input practical running distance again, user can directly be calculated
The running distance of running.
According to each current running distance, practical running distance, current step number and the step-length to be corrected, it is calculated
Corresponding current average step length, if current current average step length meets preset condition, it is just as step-length after correction
Storage when next user runs under specific running modes again, will not require user to input practical running distance again.
Preset condition can be voluntarily arranged according to demand, such as:The difference of current average step length and step-length to be corrected is one
Determine to be considered as meeting preset condition in range.Multiple in view of that may need to correct, therefore, the number of N is not restricted, until
Step-length after to correction.
The present embodiment, can be according to practical feelings of running after obtaining step-length to be corrected according to physiological information input by user
Condition is corrected step-length, to step-length after being corrected, keeps the running subsequently calculated distance more accurate, and even if user is defeated
Enter the information such as the height of mistake, can also accurately count the actual indoor running distance of user, substantially increase user's
Usage experience.
In another embodiment of the present invention, as shown in Fig. 2, the improvement based on above-described embodiment, is removed same as described above
Except, step S2 obtains the current of user's n-th running when not depositing step-length after calibration and specific running modes are opened
Step number specifically includes:
Step S21 obtains the of user's n-th when not depositing step-length after calibration and the specific running modes are opened
One step number;
Step S22 obtains the second step number of user's n-th at the end of user runs under the specific running modes;
User's n-th is calculated according to second step number of n-th and first step number of n-th in step S23
The current step number of running.
If specifically, the current step number of counting user be bracelet, wrist-watch etc can the electronic equipment that be carried always by user,
Also accounting walks user when on foot, therefore, when user opens specific running modes, can first confirm present step number, i.e., and the
One step number;After the completion of user runs, present step number, i.e. the second step number are reaffirmed;First step number is subtracted by the second step number
Afterwards, the total step number that user runs under current specific running modes, i.e., current step number are obtained.
Because that there may be repeatedly correction, currently run distance, current step number, practical running distance can be obtained every time
Deng each data are needed and are associated every time.
The present embodiment, which considers, needs that step number is zeroed out now caused by reasons walking etc. when obtaining current step number
The case where, ensure that can acquire accurate current step number.
In another embodiment of the present invention, as shown in figure 3, the improvement based on any of the above-described embodiment, except with it is above-mentioned
Except identical, step S4 is specifically included:
Step S41 when the current running distance and n-th of n-th the practical running apart from absolute value of the difference
When no more than pre-determined distance threshold value, according to the current step number of current the running distance and n-th of n-th, calculate
To the current step of n-th;
Step S42 when the current running distance and n-th of n-th the practical running apart from absolute value of the difference
When more than pre-determined distance threshold value, according to the current step number of practical the running distance and n-th of n-th, it is calculated
The current step of n-th;
The current flat of n-th is calculated according to the current step of the step-length to be corrected and n-th in step S43
Equal step-length.
Specifically, in timing, if finding that current running distance is calculated with practical running input by user apart from phase
Difference is too big, illustrates step-length to be corrected at the beginning there are prodigious problem, therefore, it is necessary to using practical running input by user away from
From calculating current step.
If being not much different with practical running distance input by user it was found that current running distance is calculated, belong to acceptable
If range, then current step is calculated using current running distance is calculated.
After obtaining current step, current average step length is obtained using step-length to be corrected.There are many calculations, example
Such as:After current step is added with step-length to be corrected divided by 2.Can certainly be other modes, such as:
After user Xiao Ming has input its physiological information, the step-length being calculated is a=0.5 meters, and 0.5 is used as and waits for school
The initial value of positive step-length.When obtaining step-length to be corrected and without step-length after correcting, Xiao Ming opens specific running modes and carries out
Running, it is N that bracelet oneself, which has counted current step number this time, after running for the first time1=5000 steps, and require Xiao Ming defeated
Enter this practical running distance, Xiao Ming is the step run on a treadmill, according to the distance input shown on treadmill X1
=2800 meters.The current running distance D that bracelet is calculated1=5000*0.5=2500 meters.If pre-determined distance threshold value is 50 meters,
Because of ︱ 2500-2800 ︱=300 > 50, therefore, current step S1=2800/5000=0.56 meters.
Current average step length bNCalculation formula can be:bN=[(N-1)a+SN]/N;
Wherein, N is that specific running modes are opened in which time, and a is step-length to be corrected, SNFor the current step of n-th, bNFor
The current average step length of n-th.
Because running for the first time when this specific running modes of unlatching, therefore, b1=[(1-1)*0.5+S1]/ 1=0.56 meters.
It can be according to current running distance and practical running apart from the specific of its difference when calculating current step in the present embodiment
Situation is calculated, and the current step being calculated is enable to provide more accurate data for subsequent correction.
Preferably, step S5 is specifically included:
Step S51 is not more than in advance when the current average step length of n-th and the absolute value of the difference of the step-length to be corrected
If when step-length threshold value, then it is assumed that correct successfully, and the current average step length of n-th is set as step-length after correcting.
Specifically, default step-length threshold value can be voluntarily configured according to the accuracy that user wants, such as:Default step-length
Threshold value is 0.1.
Examples reference is as follows:The current average step length b of first time1=0.56 meter, step-length a=0.5 meters to be corrected, ︱ 0.56-
The < of 0.5 ︱=0.06 0.1, it is therefore contemplated that correcting successfully, by b1=0.56 is set as step-length after correction.
After obtaining certain corresponding primary current average step length, if the difference of itself and step-length to be corrected is in default step-length threshold
In value, then it is assumed that this current average step length already belongs to stablize step-length, can be stored as step-length after correction,
It is calculated for subsequent running distance, no longer needs to be corrected.
Preferably, further include after step S4:
Step S6 is more than default step when the current average step length of n-th and the absolute value of the difference of the step-length to be corrected
When long threshold value, then it is assumed that correction is unsuccessful, updates the step-length to be corrected, N=N+1 with the current average step length of n-th
Afterwards, go to step S2.
If specifically, find by correct for the first time it is unsuccessful if, be necessarily required to carry out second in addition third and fourth
Secondary correction.
Specific example is as follows:
Default step-length threshold value is 0.05, the current average step length b of first time1=0.56 meter, step-length a=0.5 to be corrected
Rice, ︱ 0.56-0.5 ︱=0.06 > 0.05, it is therefore contemplated that correction is unsuccessful, step-length to be corrected is updated to a=0.56.Work as user
It is N that bracelet oneself, which has counted current step number this time, when opening specific running modes, after second of running2=4000
Step;Practical running distance X input by user2=2250 meters;The current running distance D that bracelet is calculated2=4000*0.56=
2240 meters.If pre-determined distance threshold value is 50 meters, because of ︱ 2240-2300 ︱=60 > 50, therefore, current step S2=2300/4000
=0.575 meter.Current average step length b2=[(2-1)*0.56+0.575]/ 2=0.5675 meters.︱ 0.5675-0.56 ︱=
Therefore 0.0075 < 0.05 is corrected successfully, step-length after correcting is set as by 0.5675.
If it should be noted that found in calculating process there are aliquant situation, precision that can be according to demand into
The capable preservation that rounds up, such as:3 etc. after reservation decimal point.
The present embodiment can be corrected step-length by the use of the multiple specific running modes of user, be met
Step-length after the correction of user's actual conditions makes the running being calculated under specific running modes apart from more acurrate, raising user
Usage experience.

After just when step-length, when user is again turned on specific running modes, it is no longer necessary to the current practical running distance of user's input, it can be straight
It connects according to step-length after the current movement step number of acquisition and correction, distance of running is calculated after correcting.Can be shown to user see,
Be dealt into associated electronic equipment (or account) allow user's storage, share etc..
Such as:User has on wrist-watch and runs, and step-length after correction is had existed in this wrist-watch, and user opens specific running
