After noise, by remaining useful each step in three-dimensional system of coordinate the component of acceleration value of each axle be calculated conjunction plus
Velocity amplitude, the resultant acceleration value have multiple, and the multiple resultant acceleration value is compared, finds out their maximum, secondary
Big value, minimum value and sub-minimum, by maximum, minimum value or second largest value, the further material calculation of sub-minimum；Pass through three shaft angles
Rate information is integrated to obtain the attitude information of pin, and outgoing direction can be calculated if if magnetometer is believed to correct by tri-axis angular rate
The course angle calculated is ceased, by the course angle corrected in attitude information, step-length is decomposed, obtains the actual walking displacement of people
Information（For example, it is assumed that the current walking course angle of amendment is a, step-length is L, then the horizontal range x and y to walk is：x=L*sin
(a)；y=L*cos(a)）, therefore attitude information is the determination that displacement information is walked for secondary row, the walking position most obtained at last
