Embodiment 1
[0046] The user uses the present invention to make 3D character animations, which requires real-time capture and reconstruction of various movements of the human body. The user wears the present invention according to the above method, unifies the clocks of each inertial sensing unit 101, and establishes a start Acquisition task, the user makes various actions, each inertial sensing unit 101 collects once every 10 milliseconds, and fuses and calculates the local posture information of each human body segment, and sends the collected 100 milliseconds every 100 milliseconds. The posture information data is given to the WIFI wireless router 102, and the WIFI wireless router 102 receives the data and forwards it to the computer automatically immediately, and the central computer 103 sets up a virtual 3D human body model, constantly updates the posture situation of each human body segment according to the posture information data, and sends the posture information The data is stored...
Embodiment 2
[0048] The user uses the present invention to perform medical rehabilitation analysis and evaluation, which requires capturing and reconstructing the movement of the evaluated patient's local affected area. The patient wears several inertial sensing units 101 at a specific position according to the needs, and the user uses the computer software to Unify the clocks of each inertial sensing unit 101 of the posture information acquisition system and select the local motion reconstruction mode to establish an acquisition task. The patient makes a specific action according to the requirements, and each inertial sensing unit 101 collects data every 10 milliseconds. And be fused and calculated so as to obtain the human body posture information of the patient's specific position, and send the collected posture information data to the WIFI wireless router 102 every 100 milliseconds, and the WIFI wireless router 102 will automatically forward the data to the central computer 103 immediate...
