AI Technical Summary

Problems solved by technology

Due to the high dependence of this method on other markers in the same segment, it is difficult to accurately measure the distance between markers
Even if the constraint of constant bone length is used on the basis of matrix filling, the accuracy can be further improved, but it also has the inherent approximation error of low-rank filling
[0005] The above algorithms cannot maintain the coordinate recovery accuracy of missing points and the bone length recovery accuracy at the same time when the marker points are continuously missing.

Embodiment Construction

[0107] Such as figure 1 As shown, the present embodiment takes the human body as an example, and the motion data distortion recovery method includes the following steps:

[0108] Step 1: standardize the motion data coordinates;

[0109] The human body motion capture data mainly records the spatial position of the marked points of the human skeleton and its motion trajectory information. Usually, the motion capture data directly obtains the three-dimensional coordinates of the marked points in the world coordinate system. Subsequent storage generally stores data by storing translation and rotation information of each marker, wherein the rotation information is represented by Euler angles. These data reflecting coordinate changes are stored in the AMC file, while some invariable data, such as the initial position of the marker point, degree of freedom and bone length, are stored separately in the ASF file. This storage method undoubtedly avoids data redundancy. The representat...

Abstract

The invention discloses a motion data distortion recovery method, comprising the following steps: step 1: standardize the motion data coordinates; step 2: segment and combine different parts of the human body processed in step 1; step 3: perform step 2 Segment the combined data and carry out the sliding window processing on the time axis respectively to obtain the data sequence of adjacent frames; Step 4: carry out dictionary training; Step 5: build the target function to recover human body motion data by the dictionary that step 4 obtains; The present invention The motion data distortion recovery method can maintain the bone length invariance while maintaining a good recovery effect, which makes the recovered motion sequence more natural and facilitates subsequent data storage.

Description

technical field [0001] The invention relates to the field of three-dimensional motion data processing, in particular to a motion data distortion restoration method. Background technique [0002] Motion capture (MOCAP) is a technology to obtain real motion data. It refers to recording the motion trajectory of the human body in three-dimensional space through sensing devices, converting it into abstract motion data, and finally driving objects or virtual human motion based on these data. Technology. With the rapid development of virtual reality technology, MOCAP has been widely used in various fields, such as computer animation, computer games, film and television animation, education and medicine, sports analysis, sports training, intelligent monitoring, motion simulation and other fields. In order to obtain accurate data, there are already many MOCAP technologies, among which motion capture technology based on optical sensors is the most popular technology, and representati...
