Fig. 2 is a kind of flow chart of the method for calibrated distance sensor according to an exemplary embodiment, such as Fig. 2 institutes
Show, this method is used in electronic equipment, and the range sensor is arranged in the electronic equipment, and this method includes following step
Suddenly：
In step 201, start the calibration flow of current period, the output valve of gravity sensor is obtained, as at least one
First state parameter in individual state parameter.
In the present embodiment, often the time Jing Guo a cycle is carried out once calibrated distance sensor, and the flow shown in Fig. 2 is
Calibration flow in a cycle.In the present embodiment, electronic equipment in addition to range sensor also include gravity sensor and
Light sensor.In step 201, it can specifically include and gravity sensor is read by the program being pre-configured with the electronic device
Output valve, using be used as at least one state parameter whether being met for judging calibration condition first state ginseng
Amount.
In step 202, according to the first state parameter judge electronic equipment whether according to range sensor distance
Sense the vertical state upward in direction to place.
Such as shown in Fig. 3, first direction R1, the second direction R2 and third direction R3 Special compositions right angle of pairwise orthogonal are sat
Mark system, in the horizontal plane, third direction R3 is vertical direction by first direction R1 and second direction R2.In the rectangular space coordinate
In system, the electronic equipment in Fig. 3, which is placed, in the horizontal plane, sets the distance perspective of range sensor S0 in the electronic device should side
To consistent with third direction R3, for it is vertical upward.In this case, gravity side can be learnt according to the output valve of gravity sensor
To with third direction R3 on the contrary, and should be in opposite direction with range sensor S0 distance perspective.Thus, it is possible to joined according to first state
Amount judges whether gravity direction should be in the opposite direction, if so, then illustrating electronic equipment according to distance with the distance perspective of range sensor
The distance perspective of sensor answers the vertical state upward in direction to place；Otherwise, then illustrate electronic equipment not according to range sensor
Distance perspective answers the vertical state upward in direction to place.
In step 203, it is determined that the electronic equipment does not answer direction vertical according to the distance perspective of the range sensor
When state upward is placed, determine that target parameter and at least one state parameter are unsatisfactory for calibration condition, terminate current week
The calibration flow of phase.
That is, the calibration condition in the present embodiment includes：Electronic equipment must answer direction to erect according to the distance perspective of range sensor
Directly state upward is placed, and whether this condition is met is judged especially by the output valve of gravity sensor.At this
When one condition can not be met, that is, illustrate that the output valve of now range sensor cannot function as configuring bottom in the electronic device
Make an uproar value, without obtaining the output valve of range sensor and the output valve of light sensor, without continuing its other party
The judgement in face, and directly determined in the state of target parameter and other state parameters do not obtain also target parameter and it is described at least
One state parameter is unsatisfactory for calibration condition, and terminates the calibration flow of current period.
In step 204, the output valve of the range sensor is obtained, as the target parameter.
For example, the output valve of range sensor can be read by being pre-configured with program in the electronic device, using as
The target parameter whether being met for judging calibration condition.Now, it is that range sensor exists that can only determine the target parameter
Distance perspective answer direction it is vertical upward when output valve, can not also determine if the bottom configured in the electronic device can be used as to make an uproar
Value, it is also necessary to carry out the judgement of other conditions in above-mentioned calibration condition.
In step 205, judge whether the target parameter is equal to the maximum output value of the range sensor.
In the present embodiment, range sensor has a known output valve scope (i.e. as sensor known to specification
Range), the maximum in the scope is the maximum output value of range sensor, and range sensor can not be exported than the maximum output
The bigger output valve of value.When the output valve of range sensor is equal to maximum output value, generally represent that distance perspective should side
There is object to sufficiently close to (such as within 10 millimeters of distance) range sensor upwards.
In step 206, when the target parameter is equal to the maximum output value of the range sensor, obtain light and pass
The output valve of sensor, as the second state parameter at least one state parameter.
For example, the output valve of light sensor can be read by being pre-configured with program in the electronic device, using as
The second state parameter at least one state parameter whether being met for judging calibration condition.In the present embodiment, light
The output quantity of line sensor represents its illumination received, and illumination corresponding to minimum output quantity is 0 lux.
In step 207, judge whether second state parameter is equal to 0 lux.
In a step 208, when second state parameter is equal to 0 lux, the time of preset duration is waited, is back to
Before step 204.
For example, it is determined that target parameter is equal to the maximum output value of range sensor, and the second state parameter is equal to 0 Le
Gram at this moment, the output valve of range sensor is reacquired before step 204 is back to after waiting 5 minutes to update target parameter.
As a result, the target parameter previously obtained is excluded the possibility for the value that can be made an uproar the bottom of as, but the calibration flow base of current period
The output valve of the range sensor obtained after the time of preset duration continues as new target parameter.In one kind
In possible implementation, in order to avoid the flow Infinite Cyclic of step 204 to step 208, it can reach pre- in cycle-index
Determine to terminate during number (such as 3 times) the calibration flow of current period.
In step 209, when second state parameter is more than 0 lux, determine the target parameter and it is described extremely
A few state parameter is unsatisfactory for the calibration condition, terminates the calibration to the range sensor.
That is, above-mentioned calibration condition includes：The output quantity of range sensor light sensor when equal to maximum output
Output quantity is not equal to 0 lux.Moreover, when the output quantity of range sensor is equal to maximum output, and light sensor
Output quantity when being not equal to 0 lux, determine that the current situation of electronic equipment can not carry out the calibration of range sensor, so as to eventually
Only (no longer carry out) calibration to the range sensor.
In step 210, when the target parameter is not equal to the maximum output value of the range sensor, described in judgement
Whether target parameter close to difference sum with being more than predetermined threshold value.In the target parameter with being more than default threshold close to difference sum
During value, step 203 is gone to, determines that the judgement target parameter and at least one state parameter are unsatisfactory for the calibration condition, ties
The calibration flow of beam current period.
That is, above-mentioned calibration condition includes：The output quantity of range sensor close to difference sum with being less than or equal to predetermined threshold value.
Wherein, the parameter in the electronic equipment is disposed on close to difference, for subtracting institute with the output valve of the range sensor
State bottom and make an uproar the difference comparsion size that is worth to judge whether occur close to event.For example, under same unit, range sensor
Output valve when being 700, it, which subtracts the numerical value 600 made an uproar after value 100 at bottom, understands and be participated in subsequent treatment as distance measure；
When judging close to event, numerical value 600 can respectively compared with close to difference 500, so as to judge accordingly close to event whether
Occur.In addition, in the specific implementation, above-mentioned predetermined threshold value can be in the maximum output value more than or equal to the range sensor
Chosen in the range of half.
In step 211, when the target parameter close to difference sum with being less than or equal to the predetermined threshold value, institute is determined
State and judge that target parameter and at least one state parameter meet the calibration condition, will configuration in the electronic equipment with it is described
The value of making an uproar of bottom corresponding to range sensor is changed to the size of the target parameter, terminates the calibration flow of current period.
As can be seen that the method for the present embodiment, on the basis of flow shown in Fig. 1, there is provided the school for including following content
Floating screed part：Electronic equipment answers the vertical state upward in direction to place according to the distance perspective of range sensor；Also, range sensor
The output quantity of output quantity light sensor when equal to maximum output be not equal to 0 lux；Also, range sensor is defeated
Output close to difference sum with being less than or equal to predetermined threshold value.When meeting the calibration condition, the target parameter finally given is used
Replace configuration bottom in the electronic device to make an uproar value, so as to complete the calibration flow of current period.It is corresponding with calibration condition, this
The method of embodiment is related in electronic equipment light sensor and gravity sensor in addition to range sensor, and obtaining, its is defeated
Its mark will necessarily be used by going out when being worth.
It should be noted that the present embodiment alignment condition and the calibration strategy where at least one sensor identification obtain
Flow is taken all to be directly contained among the flow of method, such as when the flow shown in Fig. 2 is being realized with computer program, school
The data of quasi- strategy are pre-configured among program, and the process for obtaining calibration strategy is interspersed in the implementation procedure of program
's.It should also be noted that, in other possible implementations, the present embodiment can carry out step in enforceable scope
Between merging, fractionation or order exchange, for example before step 204 and step 210 are arranged on into step 201, i.e., first walked
To the judgement of target parameter in rapid 210, then other judgements are carried out, without changing the reality for judging whether calibration condition is met
Matter, the disclosure are without limitation.
As can be seen that in a kind of implementation of the disclosure, at least one sensor identification can include with again
Sensor identification corresponding to force snesor, the gravity sensor are arranged in the electronic equipment；Corresponding, the step
102 include：The output valve of the gravity sensor is obtained, as one at least one state parameter；And in root
Determine that the electronic equipment does not answer direction to erect according to the distance perspective of the range sensor according to the output valve of the gravity sensor
When directly state upward is placed, determine that the target parameter and at least one state parameter are unsatisfactory for the calibration condition.It is based on
This, the disclosure can only the distance perspective of range sensor answer direction it is vertical upward when just carry out the calibration of range sensor, tie
Sharing family, (for example the distance perspective of range sensor answers direction using to the use habit of the electronic equipment of such as smart mobile phone
It is difficult to keep straight up in journey, and then can be with when electronic equipment is stood), it, which can effectively exclude distance perspective, which answers on direction, has
The situation that object blocks, so as to lift the reliability of calibration result to a certain extent.
It can also be seen that in a kind of implementation of the disclosure, at least one sensor identification can include with
Sensor identification corresponding to light sensor, the light sensor are integral with the range sensor in the electronic equipment
Set；Corresponding, the step 102 includes：The output valve of the range sensor is obtained, as the target parameter；Obtain
The output valve of the light sensor is taken, as one at least one state parameter；And in the target parameter
Equal to the maximum output value of the range sensor, when the output valve of the light sensor is more than 0 lux, the mesh is determined
Mark parameter and at least one state parameter are unsatisfactory for the calibration condition, terminate the calibration to the range sensor.Based on this,
The disclosure can identify range sensor in electronic equipment not by the range sensor and light sensor being wholely set
(i.e. light sensor can receive illumination, be blocked without object situation about correctly assembling, but the range sensor being wholely set is examined
Object has been measured to block), so as to terminate the calibration for sensor of adjusting the distance at this moment to avoid the defeated of range sensor mistakenly
Go out value to make an uproar value the bottom of as, help to lift the reliability of calibration result.
