“…In terms of the practicality of motion capture, MK has an excellent performance in hand [27], upper limb exercise [28], [29], gait [30], [31], and even jump [6], [20]. Meanwhile, Guess confirmed that the MKv2 skeleton tracker could be used to calculate the relative skeleton kinematics of hip and knee joint angle [32], Bhateja et al confirmed that the data provided by the MKv2 sensor has good stability in the air, glass, liquid, and other mediums [13].…”

“…Unlike other motion capture devices, it can be applied to a variety of complex environments without too many restrictions, effectively solving the problems of the long production cycle, low efficiency and low reduction in traditional animation production technology. It has made great achievements in many industries, such as film and television animation [2], physical training [2], [3], medical treatment [4]- [8], entertainment [9], [10], and education [11], [12] due to its advantages of convenient use and low price [13] since the release of Microsoft Kinect Xbox (MKv1).…”

The intelligent training and assessment of gymnastics movements require studying motion trajectory and reconstructing the character animation. Microsoft Kinect has been widely used due to its advantages of low price and high frame rate. However, its optical characteristics are inevitably affected by illumination and occlusion. It is necessary to reduce data noise via specific algorithms. Most of the existing research focuses on local motion but lacks consideration of the whole human skeleton. Based on the analysis of the spatial characteristics of gymnastics and the movement principle of the human body, this paper proposes a dynamic and static two-dimensional regression compensation algorithm. Firstly, the constraint characteristics of human skeleton motion were analyzed, and the maximum constraint table and Mesh Collider were established. Then, the dynamic acceleration of skeleton motion and the spatial characteristics of static limb motion were calculated based on the data of adjacent effective skeleton frames before and after the collision. Finally, using the least squares polynomial fitting to compensate and correct the lost skeleton coordinate data, it realizes the smoothness and rationality of human skeleton animation. The results of two experiments showed that the solution of the skeleton point solved the problem caused by data loss due to the Kinect optical occlusion. The data compensation time of an effective block skeleton point can reach 180 ms, with an average error of about 0.1 mm, which shows a better data compensation effect of motion data acquisition and animation reconstruction.
