Three-dimensional posture real-time analysis system and method for hand tremor of Parkinson's disease

The invention provides a three-dimensional posture real-time analysis system and method for hand tremor of Parkinson's disease. The system comprises a sensor, a data transmission device and an upper computer, the sensor is used for being bound to the corresponding position of an arm and obtaining angular velocity and acceleration data. The data transmission device is used for transmitting data obtained by the sensor to the upper computer; the upper computer comprises a data processing module, a main controller, a three-dimensional human body model and a user interface, the data processing module is used for generating a control instruction according to acquired data and sending the control instruction to the main controller, and the main controller enables the three-dimensional human body model to display hand postures in real time according to the control instruction and sends the hand postures to the user interface for display; the system can display the tremor frequency of a patient in real time so as to a
