Degree meter, which is corresponded in x-axis, y-axis and z-axis in range, to be fluctuated, that is, exports the acceleration value of abscissa, ordinate and ordinate all
It is 0.
In practical application (i.e. gyroscope is not calibrated or calibration is inaccurate), accelerometer is in each axis of x-axis, y-axis and z-axis
There is certain acceleration value upwards, is denoted as R=ofsetVecA (x, y, z).Processor in intelligent glasses 11 reads acceleration
It is offsetVecA (x, y, z) that the detection data exported, which is counted, as initial detecting data.
After user 13 wears intelligent glasses 11, intelligent glasses 11 are in the second state at this time.In the second condition, accelerate
Degree meter is in active state, and can detect that detection data, processor read the detection data and make this real-time detector data in real time
VecA (x, y, z).
Finally, processor obtains initial detecting data offsetVecA (x, y, z) and real-time detector data VecA (x, y, z)
Vector sum to get to correction detection data R such as following formulas：
R=VecA (x, y, z)-offsetVecA (x, y, z).
It should be noted that VecA (x, y, z) can be the average value of multigroup real-time detector data or R can be pair
The average value of multigroup real-time detector data, particular content is answered to please refer to the corresponding content of gyroscope, details are not described herein.
Finally, correction detection data is transferred to the camera module of intelligent glasses, such camera module root by processor
The posture that can be adjusted camera according to correction detection data, prevents picture crooked, it is ensured that picture accurate is made to show.
