Detailed description of the invention
Example is described implementation of the disclosure with reference to the following drawings,
Fig. 1 illustrates the length-measuring appliances of embodiment according to the present invention；
Fig. 2 illustrates the length-measuring appliance with second feature of embodiment according to the present invention, and
Fig. 3 illustrates the method for measuring length of embodiment according to the present invention.
Specific embodiment
Fig. 1 illustrates the length-measuring appliances of embodiment according to the present invention.Length-measuring appliance 100 include wheel 102,
For sensing the sensor of the amount or angular distance that rotate and being connected to sensor to determine when wheel 102 is on the surface of object
The controller 110 of length when rolling.Length-measuring appliance 100 is characterized in that sensor includes at least one first rotation
Sensor 104, it includes gyroscope, magnetometer and Inertial Measurement Unit (IMU) which, which is selected from,
Group.
In another embodiment, in length-measuring appliance 100, wheel 102 is coupled at least one first gear
(not shown), the first rotation sensor 104 are placed in the first gear.Alternatively, first gear can be further with
The engagement of two gears, the first rotation sensor 104 are placed in the second gear.
In one embodiment, a gyroscope is only provided as the first rotation sensor 104.Now, when 102 edge of wheel
When determining the surface scrolls of object of its length, the accumulation at the angle from gyroscope and calculated, that is, the child's hair twisted in a knot-childhood.From top
The signal of spiral shell instrument gives radian per second in three axis.However, being only from the output in relation to axis by controller 110
It manages and other output signals of other axis is ignored.The primary complete rotation of wheel 102 means that the distance advanced is
Round perimeter, that is, 2*pi*r.
Wherein, the radius of r=wheel 102, and
pi = 3.14。
Therefore, length (L) is determined based on following calculating
Child's hair twisted in a knot-childhood/360 L=2*pi*r*.
In another embodiment, a magnetometer is only provided as the first rotation sensor 104.Using magnetometer, lead to
The variation of the pattern of observation output signal is crossed to measure angle.Once primary rotation is completed, by the value and initial value of magnetometer measures
It is identical.Magnetometer is used in after the calibration relative to noise.The child's hair twisted in a knot-childhood of rotation is calculated.By magnetometer, surveyed using following formula
Amount/calculating deflection:
Angle=atan (By/Bx)
Wherein, Bx and By is the magnetic field value using magnetometer measures.The variation at angle gives the angle of rotation.Child's hair twisted in a knot-childhood is then under use
Formula is converted into length:
Child's hair twisted in a knot-childhood/360 L=2*pi * r*.
In another embodiment, IMU is only provided as the first rotation sensor 104.IMU includes gyroscope and acceleration
Meter.IMU may further include magnetometer.By merging the value from gyroscope and accelerometer, quaternary number
(quaternion) it is obtained.By quaternary number, Eulerian angles are calculated.By observing the variation of Eulerian angles, the child's hair twisted in a knot-childhood of rotation is counted
It calculates, then length is calculate by the following formula:
Child's hair twisted in a knot-childhood/360 L=2*pi*r*.
At least one first rotation sensor 104 may include gyroscope and magnetometer.When being used together with gyroscope,
Magnetometer improves the accuracy of the detection of the rotation of wheel 102.Similarly, can be used IMU instead of magnetometer and and gyro
Instrument comes together to improve accuracy.Further, all three first rotation sensors 104 are used.In another alternate embodiment
In, length is measured using only magnetometer and IMU.In addition, the first of two same types can be used in order to improve accuracy
Rotation sensor 104 rather than two different types, such as two gyroscopes rather than a gyroscope and a magnetometer.
Wheel 102 includes gripping surface.Gripping surface includes but is not limited to tooth, pointed tooth, rubber material and analog.It holds
Surface can be realized complete and correct rotation and avoid any sliding.Sliding leads to mistake or incorrect information.Therefore, half
Diameter includes increased thickness due to gripping surface.
When wheel 102 is touched surface and rolled, linear measure longimetry is initialised.When wheel 102 is lifted, measure
At.This is activated by using pressure sensor, and the pressure sensor is when wheel 102 lies on the table on the surface to controller
110 issue signal.Alternatively, length-measuring appliance 100 includes switch.Switch is pressed with the starting point of indicating length measurement simultaneously
And the end point being pressed again to indicate measurement.Once the length from starting point to end point is determined by controller 110, length
It is stored in the memory cell of controller 110 for using in the future.Length can also be sent to output device 112.
Output device 112 includes the display screen for being connected to length-measuring appliance 100 itself, exterior display screen, external calculating
Device, printer, server and analog.It includes computer, desktop computer, kneetop computer, plate that external computing device, which is selected from,
The group of computer, smart phone and analog.Controller 110 passes through the wired or wireless means of such as Wi-Fi, bluetooth and analog
It is connected to output device 112.
Fig. 2 illustrates the length-measuring appliance with second feature of embodiment according to the present invention.Length-measuring appliance
100 further comprise at least one second rotation sensor 106, which is installed in length
It spends in the main body 108 of measuring device 100 and is connected to controller 110.Carry out measurement of length as depicted in figure 1.However,
Second rotation sensor 106 be employed for sensing length-measuring appliance 100 relative to the rotation on surface angle with for length
Measurement, wheel 102 are contacted on a surface.Second rotation sensor 106 is placed in main body 108, to sense length
Angle of the measuring device 100 relative to the axis rotation perpendicular to surface.For complete from 106 received signal of the second rotation sensor
At the child's hair twisted in a knot-childhood for including accumulation sum.In other words, the second rotation sensor 106 be used to measure the curvature on surface.
In one embodiment, input signal is being received from the first rotation sensor 104 and the second rotation sensor 106
In the case of, the shape in the path followed by the wheel 102 on surface is plotted in two-dimentional (2D) plane, and coordinate is counted
It is
X=L*Cos (θ), and
Y = L*Sin (θ)
Wherein, θ is from the angle of the rotation of the received length-measuring appliance 100 of the second rotation sensor 106.Using from the first rotation
Turn the data of both sensor 104 and the second rotation sensor 106, the shape of object is estimated.Further, it is also possible to utilize length
Measuring device 100 draws the multidimensional shape of such as three-dimensional (3D).
Similarly, facilitate the rotation of estimated length measuring device 100 together from the received output of IMU and magnetometer
Angle.Calculating and the therefore robustness of the calculating of length which increase the child's hair twisted in a knot-childhood.
In one embodiment, controller 110 in real time will be from the first rotation sensor 104 and the second rotation sensor
106 received processed data are sent to output device 112.Alternatively, when output device 112 is connected to controller 110
