The invention discloses a motion data processing method and a motion data processing system for a motion practice beat, wherein the method comprises the following steps of: through a motion sensor arranged the in motion practice beat, the motion data of the motion practice beat is collected at preset time slot so as to form a plurality of sampling points within a period of time; the motion data of each sampling point is subjected to data pretreatment, and the null shift of the motion sensor and the electromagnetic interference around the environment are eliminated; and according to the motion data after data pretreatment, the posture angles of the motion practice beat at each sampling point relative to the reference coordinate system are calculated, and according to the posture angles as well as the motion data, the stress information, rotation information as well as spatial position information of the motion practice beat at each sampling point are obtained.
Description
technical field [0001] The invention relates to the field of motion recognition, in particular to a motion data processing method and system for motion practice shots. Background technique [0002] When people perform various sports, they often hope to be able to intuitively see their own movement trajectory, strength, speed, position and other information during exercise. Especially for professional athletes, this information can help improve training effects. Correct some bad movement habits, etc. The recognition of motion first requires the analysis of motion parameters. The analysis of motion parameters refers to the intensive collection of the spatial position (spatial coordinates) of a moving object in three-dimensional space at each moment during a period of motion at a certain time interval. The attitude and linear velocity of the object, etc. The application field of quantitative analysis of sports parameters is not only in sports aids and sports practice equipmen...
