Abstract

The invention discloses a Kinect-based high-precision unmarked whole-body motion tracking system, which comprises a skeleton node data acquisition unit, a coordinate conversion unit, a data constraintprocessing unit, a skeleton data weight calculation unit, a position information acquisition unit and a motion tracking information acquisition unit. Through acquiring target skeleton node data, anda confidence coefficient of the target skeleton node data is obtained, therefore, a data layer weight is obtained; and a weight allocation data observation model is obtained according to the data layer weight and a system layer weight, a data observation model is allocated according to the weights, a data second-order prediction model is tracked, position information of the skeleton node data is obtained by performing data fusion through Kalman filtering, and motion tracking information corresponding to the skeleton node data is obtained according to the position information. According to theKinect-based high-precision unmarked whole-body motion tracking system, the confidence coefficient and the bone data weight of the target bone node data are calculated, and the position information isacquired, so that the motion tracking information is obtained, and the human body motion posture capturing precision is improved.

Description

technical field [0001] The invention relates to the field of virtual reality technology, in particular to a Kinect-based high-precision unmarked whole-body motion tracking system and method. Background technique [0002] With the development of computer technology, the ways of human-computer interaction are becoming more and more diverse. Human-computer interaction refers to the process of information exchange between humans and computers using a certain dialogue language to complete certain tasks in a certain interactive way. The application of human-computer interaction in virtual reality has become very common, especially in games, medicine, and biological research. Taking the capture of human motion posture in games as an example, Kinect (somatosensory controller, sensor) is usually used to capture human motion posture. Kinect is a posture capture device based on computer vision. The device integrates a depth camera, an RGB camera and an infrared emitting device. It us...
