METHOD AND APPARATUS FOR CALIBRATING MOTION DATA, TERMINAL DEVICE AND STORAGE MEDIUM

摘要

A method for calibrating motion data, which is applicable to the technical field of computers, comprising: acquiring first motion data of a first number of frames of an inertial device and second motion data of a second number of frames of a rigid body (S101), wherein the difference between a first starting frame corresponding to the first motion data and a second starting frame corresponding to the second motion data is a preset number of frames; from the first motion data, sequentially intercepting multiple groups of third motion data with the same number of frames as the second number of frames, and recording the number of offset frames between a third starting frame and the second starting frame of each group of the third motion data (S102); calculating a transformation matrix in which the second motion data is transformed into each group of the third motion data, and calculating an error corresponding to the transformation matrix (S103); and using the transformation matrix that has the smallest error and the number of offset frames corresponding to the transformation matrix as a calibration result (S104). The delay relationship and attitude relationship between calibration rigid body data and inertial device data are achieved, and the problem in which there is currently no way to calibrate rigid body data and inertial device data is solved.
