3rd, embodiment of the method
Fig. 7 is refer to, Fig. 7 is a kind of processing method embodiment signal of spatial interaction sensor raw data in the present invention
Figure.
A kind of processing method of posture initial data, the intelligent position provided using system embodiment follows the trail of manipulation pen, on
Stating intelligent position tracking manipulation pen includes processing unit 21, motion sensor 22 and communication unit 28, and processing method includes:
A, motion sensor obtain a manipulation posture initial data, are transferred to processing unit 21 and are handled, wherein, nine axles
Motion sensor 22 includes acceleration transducer unit 22a, gyro unit 22b and geomagnetic sensor unit 22c.Motion-sensing
Device is nine axis movement sensors 22, and the infrared signal that interactive device tracking infrared emission device is sent can only determine to manipulate the sky of pen
Between coordinate position, can not follow the trail of manipulation pen relative to interactive device screen entire motion posture.Nine axis movement sensors 22
It is the combination of three kinds of sensors:3-axis acceleration sensor unit 22a, three-axis gyroscope unit 22b and three axle geomagnetic sensors
Unit 22c, three parts cooperate, effect.Using acceleration sensor and gyro unit 22b, equipment can be described substantially
Entire motion state.But with prolonged exercise, can also produce Accumulated deviation, it is impossible to accurate description athletic posture, such as
Operation control picture run-off the straight.Electronic compass (geomagnetic sensor unit 22c) passes through absolute direction-pointing function using magnetic field of the earth is measured
Compensation is modified, Accumulated deviation can be effectively solved, so as to correct the direction of motion, attitude angle, the motion dynamics of manipulation pen
With speed etc..
B, processing unit 21 read the initial data, judge whether the initial data is effective, if it is not, then performing step
A, if so, then performing step C;
Easily there is spillover in nine each data progress data samplings of axis movement sensor 22, if occurring overflowing now
As the initial data of nine axis movement sensor 22 is invalid, then needs re-request to obtain the data, if being overflowed without data, to reading
Initial data carry out mean filter.
C, 21 pairs of the processing unit initial data carry out mean filter, and obtain manipulation pen by data anastomosing algorithm
Euler's angular dimensions and quaternary number;
Acceleration transducer unit 22a and gyro unit 22b interference noises in the axis movement sensor 22 of consumer level nine
Very big, being integrated by taking plane gyro as an example with ADI gyro unit 22b can drift about 2 degree or so for one minute, it is this under the premise of
If correcting three axis accelerometer if no magnetic field and gravitational field, then after substantially 3 minutes the actual posture of manipulation pen and
Measurement output posture is just changed completely, so, under low price gyro unit 22b and acceleration transducer unit 22a framework
It must be modified with field vector.Nine axle sensors in the present embodiment are using three-dimensional gyro unit 22b come quick
Track intelligent position follow the trail of manipulation pen three-dimensional posture, it using gyro unit 22b as core, while also measurement acceleration and
The direction in earth's magnetic field provides reliable reference for system.The absolute angular speed in three directions of specific measurement carrier, acceleration with
And magnetic field intensity, and use particular sensor initial data fusion method and Kalman filtering information fusion obtain the quaternary of carrier
Number, attitude data etc..Real-time Integrated Algorithm is needed to be provided accurately for system, reliably, timely and stable posture output.From
Gyro unit 22b, acceleration transducer unit 22a and geomagnetic sensor unit 22c in nine axis movement sensors 22 is complete
Portion is transferred in processing unit 21.Processing unit 21 is according to specific algorithm and the demarcation being stored in flash storage
Data processing comes from nine axis movement sensor initial data, and as its rudimentary algorithm, processing unit 21 uses adaptive Kalman
The dynamic condition that filtering algorithm, adjust automatically and adaptation are continually changing, without outside artificial intervention, nine axis movement sensors 22
It is vulnerable to interference, the influences of noise such as feedback motor, power supply and operating personnel operation behavior itself when detecting data, therefore
Need to carry out mean filter to the sensing data to reading, processing unit 21 carries out mean filter to sensor raw data,
And the Euler's angular dimensions and quaternary number for manipulating pen are obtained by data anastomosing algorithm..
D, by communication unit 28 by manipulate pen Euler's angular dimensions and quaternary number be transferred to specific interactive device, it is determined that
Manipulate the spatial attitude of pen.
Interactive device receives from intelligent position and follows the trail of Euler's angular dimensions and the quaternary number that manipulation pen is transmitted, in real time dynamic
The corresponding manipulation cursor of display, without doing further fusion treatment to initial data.
Communication unit 28 is communicated by USB data line or HID cables with interactive device.
The transmission line section of communication unit 28 is divided into the USB data line using HID host-host protocols, and communication unit 28 uses USB
During data line transfer, USB data line is electrically connected with processing unit 21, and lip pencil housing 10 is provided with and used cooperatively with USB interface 28a
Breach, compared to traditional HDMI data wires, USB data line versatility is stronger.
Implement the processing method that a kind of intelligent position proposed by the present invention follows the trail of manipulation pen and posture initial data, manipulate pen
Intelligent control circuit plate in processing unit is set, to acceleration transducer unit 22a, the gyroscope in nine axis movement sensors
The acceleration parameter of the three degree of freedom that unit 22b and geomagnetic sensor unit 22c are detected respectively, angular speed parameter and
Directioin parameter carries out fusion treatment, obtains the Euler's angular dimensions and quaternary number of manipulation pen, is transferred to specific interactive device, interaction
Equipment only needs to the space coordinate and sensor raw data that manipulate pen being overlapped, without doing further fusion treatment, greatly
The direction sensor of geomagnetic sensors detection in the big processing load for reducing interactive device, nine axis movement sensors 22 is original
The space based sensor data that data follow the trail of existing intelligent position manipulation pen carries out effective amendment, improves to intelligent position
Follow the trail of and be connected in manipulation space motion location tracking precision, the present invention using the USB data line of HID protocol with interactive device,
Improve the reliability of data transfer.Implement instant invention overcomes existing manipulation pen when being used cooperatively with interactive device, hand over
Even there is deadlock phenomenon, cursor and the problem of " drift " phenomenon causes poor user experience occurs in mutual device plays interim card.
Presently preferred embodiments of the present invention is these are only, is not intended to limit the invention, it is all in the spirit and principles in the present invention
Within, any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
