When carrying out the measurement of wall sag, user, which needs to adjust terminal fuselage in real time, meets the location status of terminal
The standard of sag measurement could make the vertical deviation angle of terminal accurately indicate the sag of tested wall, referring specifically to Fig. 2A.
Fig. 2A is the method flow diagram of the wall sag detection method provided in one embodiment of the invention, the wall sag
Detection method is applied in terminal shown in figure 1A, which includes the following steps:
Step 201, it obtains the pitch deviation angle of terminal in real time and vertical deviation angle, the pitch deviation angle is terminal screen institute
Plane and vertical direction angle, which is vertical side and the angle of vertical direction of terminal, this is vertical
Side is fitted in tested surface of wall.
In practical applications, the vertical side of terminal is close to tested metope by user in parallel, and terminal can obtain in real time at this time
Pitch deviation angle and the vertical deviation angle of present terminal are taken, user continues the position for adjusting terminal according to the pitch deviation angle,
During this, the vertical side of terminal is close to tested metope in parallel always.
Pitch deviation angle mentioned here is used to indicate the angle between terminal screen and vertical direction, and pitch deviation angle is got over
Greatly, illustrate that the angle of terminal screen deviation vertical direction is bigger；Pitch deviation angle is smaller, illustrates that terminal screen deviates vertical direction
Angle it is smaller, when pitch deviation angle is infinitely small, it is believed that the plane where terminal screen is overlapped with vertical direction at this time.
It optionally, can be with real-time display pitch deviation angle, with for reference on terminal screen.Terminal can also be by obtaining
The size at pitch deviation angle is taken, user is prompted with voice mode.Here the form of expression at pitch deviation angle is not defined.
Since the vertical side of terminal is close to tested metope in parallel always, vertical deviation angle said here is used for
Indicate tested metope currently with the angle of vertical direction.
Step 202, when the pitch deviation angle of acquisition is less than predetermined angular threshold value, whether terminal is in phase in the same time for detection
To stable state.
User needs the size according to pitch deviation angle when adjusting terminal location, judges whether to need to continue adjustment eventually
The position at end.When terminal notifying pitch deviation angle is less than predetermined angular threshold value, it is believed that plane where terminal screen with
Vertical direction essentially coincides, and user can stop adjusting the position of terminal at this time, and terminal is made to keep relative stability state, terminal
Inside starts to execute the testing mechanism of metastable state.
In order to improve the precision to vertical missing angular measurement as far as possible, what predetermined angular threshold value here was arranged is got over
Small, the vertical deviation angle measured is then closer to the practical sag of tested wall.But in practical application, since user adjusts manually
The pitch deviation angle of whole terminal, if predetermined angular threshold value setting is too small, it is required that user's progress is more accurate or smaller
The adjustment of amplitude, in the case where the pitch deviation angle of terminal is unable to satisfy less than predetermined angular threshold value, terminal is unable to get vertical
The straight angle of deviation.Therefore, predetermined angular threshold value here can be determined according to actual measurement accuracy, can also be by user according to certainly
Oneself needs measurement accuracy to set.
Metastable state mentioned here refers to that terminal is in opposing stationary state relative to tested metope, it is general and
Speech, user want the sag of measurement wall, need to guarantee that terminal is in metastable state, so that the pitch deviation angle of terminal is tieed up
Hold the state less than predetermined angular threshold value.
Therefore, in actual measurement, terminal needs to meet certain measuring condition, in addition to needing to meet pitch deviation angle
Condition, the metastable state also belong to one of measuring condition.
It should be noted that in practical applications, the environment as where terminal is not ecotopia, by the external world with
And the influence of human factor, the terminal that user holds are not likely to be at totally stationary or complete stability state, therefore this
In the metastable state said refer to that angular acceleration of the terminal in three axis directions is very small, such as respectively less than angular acceleration
Threshold value, angular acceleration threshold value here can be set as smaller numerical value.
Step 203, when terminal is in metastable state, the vertical deviation angle obtained in the same time is locked, this is exported and hangs down
The straight angle of deviation.
When terminal meets the standard at pitch deviation angle and metastable state simultaneously, terminal is according to current location, locking
And export the vertical deviation angle at the moment.The vertical deviation angle is the angle of tested metope and vertical direction.
Optionally, which can be shown on a terminal screen with written form, can also be broadcast by voice
The mode of report is broadcast to user, is not defined here to the output form of the vertical deviation angle.
In conclusion wall sag detection method provided in an embodiment of the present invention, by the pitch deviation for determining terminal
Angle be less than predetermined angular threshold value and it is relatively stable when, the vertical deviation angle obtained in the same time is locked and exports, due to bowing for terminal
When facing upward the angle of deviation less than predetermined angular threshold value, show plane where terminal screen close to vertical direction or for vertical direction, this
The vertical deviation angle of Shi Suoding is tested the sag of wall compared with energy accurate representation, therefore solves terminal in the related technology and putting vertically
The vertical missing measurement error biggish technical problem as caused by location error when setting；Reach and measurement result can be improved
Precision technical effect.
In practical applications, user judges whether the position for needing to continue to adjust terminal according to the pitch deviation angle of terminal.
In one possible implementation, terminal screen provides reference by the corresponding index line in display pitch deviation angle for user,
Referring specifically to Fig. 2 B and Fig. 2 C.
Fig. 2 B is the method flow diagram of the wall sag detection method provided in another embodiment of the present invention, which hangs down
It spends detection method to be applied in terminal shown in figure 1A, which includes the following steps:
Step 211, the real-time display reference line parallel with the terminal transverse sides on the screen of terminal.
In order to show the pitch deviation angle of terminal to user, terminal can show that is parallel to a terminal transverse direction on the screen
The static lines of side, the static state lines can be the reference line at characterization terminal pitch deviation angle.
In one possible implementation, which may be displayed on middle position namely base of terminal screen
Directrix passes through the central point of terminal screen.
In alternatively possible implementation, due to the part display area on terminal screen, it is possibly used for showing
For the control or operating instruction of user's operation, thus the reference line also may be displayed on terminal screen top half region or
Person lower half portion region.
Here the position that is particularly shown of the reference line is not defined.
In user's actual rotation terminal, the relative display position of the reference line on the screen does not change.
Step 212, the pitch deviation angle of terminal is obtained in real time.
During actual measurement, in order to enable available accurately vertical deviation angle, needs the pitching by terminal inclined
Declinate is adjusted to 0 as far as possible, namely close to predetermined angular threshold value.Therefore, in measurement process, user needs continuous adjustment
The pitch deviation angle of terminal.
And in order to guide user adjust pitch deviation angle, and in order to assist user determine adjustment during bow
The angle of deviation is faced upward whether close to 0, terminal can obtain the pitch deviation angle of terminal in real time and be shown.
Terminal deviates the angle of vertical direction according to terminal screen, passes through the pitch deviation of the real-time computing terminal of calculation method
Angle.
The method that calculation method mentioned here can be tangent antitrigonometric function.
According to itself movement, the original acceleration of gravity for obtaining itself is obtained terminal by the decomposition accelerated to the gravity
Obtain the original acceleration of gravity A on three mutually perpendicular direction in spacesx, AyAnd Az, then these three original acceleration of gravity into
Row high-pass filtering obtains three axis linear acceleration LAx、LAyAnd LAz, remake the difference acquisition of original acceleration and linear acceleration
Three axis acceleration of gravity Gx、GyAnd Gz, finally using three axis acceleration of gravity calculate obtain pitch deviation angle, calculation formula be θ=
arctan(|Gx|/|Gy|)*180/π。
Step 213a will be corresponding with the pitch deviation angle when generating pitch deviation angle, the screen of the terminal is upward
Direction is determined as positioned at the top or lower part of said reference line, while calculating offset distance corresponding with the pitch deviation angle, should
Distance is in positive correlation with the pitch deviation angle.
In general, the same pitch deviation angle can correspond to two offset directions of terminal screen.
When terminal screen is swung back relative to vertical direction, terminal screen is upward at this time, for example screen is obliquely,
The offset direction of terminal screen can be determined as to the top or lower part of said reference line.
It can be calculated according to predetermined computation method corresponding with the pitch deviation angle at terminal quarter while determining offset direction
Offset distance, the offset distance and the pitch deviation angle are in positive correlation.
Forward direction correlation mentioned here refers to: pitch deviation angle is bigger, and offset distance is bigger；Conversely, pitch deviation angle
Smaller, offset distance is smaller.
The predetermined computation mode can be it is linear, be also possible to it is nonlinear, here not to the predetermined computation mode into
Row limits.
Step 213b will be corresponding with the pitch deviation angle when generating pitch deviation angle, the screen of the terminal is downward
Direction is determined as positioned at the top or lower part of said reference line, while calculating offset distance corresponding with the pitch deviation angle, should
Distance is in positive correlation with the pitch deviation angle.
Relatively, when terminal screen leans forward relative to vertical direction, terminal screen is downward at this time, such as screen court
The offset direction of terminal screen can be determined as the top or lower part of said reference line by obliquely downward.
Similarly, it can be calculated according to predetermined computation method inclined with the pitching at terminal quarter while determining offset direction
The corresponding offset distance of declinate, the offset distance are in positive correlation with the pitch deviation angle.
Forward direction correlation mentioned here refers to: pitch deviation angle is bigger, and offset distance is bigger；Conversely, pitch deviation angle
Smaller, offset distance is smaller.
The predetermined computation mode can be it is linear, be also possible to it is nonlinear, here not to the predetermined computation mode into
Row limits.
Step 214, the index line parallel with the reference line is shown in the side of the reference line according to the direction, the index line
The distance between the reference line is distance corresponding with the pitch deviation angle.
After the offset direction and offset distance that terminal determines itself, terminal can show one on the screen and be parallel to base
The display position of the dynamic instruction line of directrix, the dynamic instruction line changes with the variation of the angle of terminal offset from perpendicular,
The angle of offset from perpendicular to the terminal screen for reminding user current, specifically may refer to Fig. 2 C, and Fig. 2 C is the present invention
The schematic diagram of the pitch deviation index line provided in one embodiment.
As shown in Figure 2 C, obliquely, terminal goes out one according to itself offset direction, real-time display to terminal screen at this time
Index line 2102 positioned at 2101 top of reference line, allow user according to the index line 2102 accurately by terminal screen into
Capable adjustment of leaning forward, makes index line 2102 as close as possible to the reference line 2101, or be overlapped with the reference line 2101, thus satisfaction pair
The condition of the progress sag detection of wall 2103.
Optionally, the offset direction and the offset distance can also be broadcasted by speech form or text importing form to
User is not defined the form of expression of the offset direction and the offset distance here.In conclusion the embodiment of the present invention mentions
The wall sag detection method of confession, by the pitch deviation angle for determining terminal be less than predetermined angular threshold value and it is relatively stable when,
The vertical deviation angle obtained in the same time is locked and exported, when being less than predetermined angular threshold value due to the pitch deviation angle of terminal, is shown
Plane where terminal screen close to vertical direction or is vertical direction, and the vertical deviation angle locked at this time is compared with energy accurate representation quilt
The sag of wall is surveyed, therefore solves terminal vertical deviation angle as caused by location error in vertical place in the related technology
The larger technical problem of measurement error；The technical effect that the precision of measurement result can be improved is reached.
In addition, by the offset direction of real-time display terminal screen and deviation distance on a terminal screen, so that user can
To be accurately adjusted to the position of terminal screen, equally solve the relevant technologies according to the offset direction and deviation distance
Middle terminal biggish technical problem of vertical missing measurement error as caused by location error in vertical place；Having reached can
To improve the technical effect of the precision of measurement result.
It should be noted that the embodiment of the present application is in practical applications, it can also direct computing terminal offset from perpendicular
Angle namely pitch deviation angle, and at the terminal by the pitch deviation angle real-time display, user is according to the angle in the terminal
Adjust the angle of terminal offset from perpendicular.
For example, according to the pitch deviation angle got, positive negative direction corresponding with pitch deviation angle is calculated, when
When the screen of terminal is upward when generating pitch deviation angle, set one of positive or negative for the value at obtained pitch deviation angle；
When generating pitch deviation angle, the screen of terminal is downward, by the value at obtained pitch deviation angle be set as positive or negative in it is another
Kind.
By taking the angle value at pitch deviation angle is 30 ° as an example, when generating pitch deviation angle, the screen of terminal is upward, obtain
And the pitch deviation angle shown is+30 °；When generating pitch deviation angle, the screen of terminal is downward, the pitching that obtains and show
The angle of deviation is -30 °.
In practical application, other than meeting the condition at pitch deviation angle, terminal also needs the state of keeing relative stability, ability
Guarantee that current pitch deviation angle meets the measurement standard of wall sag always, terminal judges itself whether be in relatively stable shape
The process of state may refer to Fig. 2 D.
Fig. 2 D is the method flow diagram of the wall sag detection method provided in further embodiment of the present invention, which hangs down
It spends detection method to be applied in terminal shown in figure 1A, which includes the following steps:
Step 221, the first mean square deviation of acceleration of the terminal in orthogonal three axial directions is obtained.
Terminal starts to detect itself whether be in opposing stationary shape relative to metope after the condition for meeting pitch deviation angle
State.
In actual implementation, since terminal is not in absolute rest state, terminal has steric acceleration, at this time terminal
The numerical value of the acceleration can be decomposed, obtain the numerical value of mutually perpendicular three acceleration on direction in space, terminal
By certain frequency acquisition, the first mean square deviation of three steric accelerations is obtained respectively.
Assuming that first mean square deviation be A, and in 1s 16 acceleration of continuous acquisition numerical value, then the first mean square deviation calculate
Formula can indicate are as follows:Wherein xiIndicate the numerical value of each acceleration of acquisition,Indicate the 16 of acquisition
The average value of the numerical value of a acceleration.
First mean square deviation can indicate motion state of the terminal current time on three direction in spaces.
Step 222, when at least one of first mean square deviation of the acceleration in above three axial direction is greater than first just
When poor threshold value, the second mean square deviation of acceleration of the computing terminal in orthogonal three axial directions.
In first mean square deviation of above three direction in space, when at least having one greater than the first mean deviation threshold, eventually
End may determine that itself is in the motion state relative to metope at this time, or determines that terminal itself is currently at unstable shape
State.
After determining the motion state, show user at this time still in the position of adjustment terminal screen, terminal according to itself
Motion state continues to calculate the mean square deviation on above three direction in space, and mean square deviation at this time is denoted as the second mean square deviation.
