Study On Simulations Of Human Movement Synthesis Based On Muscle

In recent years, computer technology has made rapid progress. At the same time, virtual reality technology is widely known. In the game, film and television entertainment, medical and military fields it has been widely used, and it not only enrichs people's lives, but also has brought great convenience to people's lives. So how to simulate a more realistic human model and human movement in the virtual environment has a very high research value.Human motion synthesis technology is involved in human anatomy, computer graphics, human body kinematics, computer science and many other disciplines of knowledge, so it is extremely challenging and complex. Based on the deep analysis of the human movement system, this thesis determines the main skeleton which reflects the real structure of the human body, as well as the joints and muscles which play a key role in human movement. Based on the anatomy, the human geometry model is established under the premise of full consideration of authenticity and operability.It is made up of the joints, bones, and muscles, Secondly, the hierarchical structure of the human motion system is expressed, and the joints are classified according to the different degrees of freedom. The rotation of the joint around the coordinate axis is represented by a matrix. The rotation of the joint around any axis is indicated by the quaternion. Then, the local coordinate system of wrist joint, elbow joint, shoulder joint, hip joint, knee joint and ankle joint are established by selecting the anatomic feature points. Binding between bones is realized by establishing the mapping relationship between the local coordinate system. Finally, the motion capture data is analyzed. In order to apply the motion data to the human geometric model established in this thesis, the scale factor is determined to match the human model. According to the motion capture data, the rotation angle of the joint is solved by using the inverse kinematics. The kinematic parameters are solved by using the multi-rigid body kinematics and dynamics formula. By applying the space mechanics balance constraint, the effective human motion constraint mechanism is obtained, and the simulation of human motion is realized.Experimental results show that the simulations of human motion in this thesis can meet the Newton's law of motion, and the effect is more real, natural.
