<p>The present invention provides a motion parameter determination method and device and motion auxiliary equipment. Actual acceleration of each sampling moment is calculated from a motion starting moment to a motion ending moment of the state of a period of motion through a backtracking algorithm by using motion data of each sampling moment, the motion data being formed by acceleration of an identified object sampled by a three-axis acceleration sensor, an angular velocity of the identified object sampled by a three-axis gyroscope, and an included angle, sampled by a three-axis magnetic field sensor, of the identified object relative to a three-dimensional geomagnetic coordinate system. The actual acceleration is obtained by removing influence of acceleration of gravity from the acceleration sampled by the three-axis acceleration sensor. With the present invention, complexity of a system can be reduced, and the influence of environment, particularly light, on accuracy is low.</p> |
