Human body posture tracking system based on micro inertial sensor and using method of human body posture tracking system based on a micro inertial sensor

Abstract

The invention discloses a human body posture tracking system based on a micro inertial sensor. The human body posture tracking system comprises a data acquisition system, a wireless data transmissionsystem and a computer data processing system, wherein the data acquisition system comprises one or more data acquisition modules, each data acquisition module comprises one or more micro-inertia sensing units, a power management unit, a wireless transmitting device and a main control processing module, each micro-inertia sensing unit comprises a voltage reduction and current stabilization module and a nine-axis inertia sensor, each voltage reduction and current stabilization module is used for filtering clutters and stabilizing voltage for the corresponding nine-axis inertial sensor, and eachnine-axis inertial sensor comprises a three-axis accelerometer and a three-axis gyroscope which are respectively used for acquiring an acceleration value and a gyroscope angular velocity value. The invention provides a miniaturized, real-time, low-cost and wearable human body posture tracking system, which adopts a wireless mode for communication, and can track and analyze the posture of a human body in real time on the premise of not influencing the action of the human body.

Description

technical field [0001] The invention relates to the technical fields of attitude detection, wireless remote sensing and sports medicine, in particular to a human body attitude tracking system based on a micro-inertial sensor and a method for using the same. Background technique [0002] Attitude tracking technology is widely used in film and television animation, virtual reality, biomedicine, human rehabilitation and other fields, and has become one of the most popular technologies in the current technology field. Existing attitude tracking technologies are mainly used in aerospace (such as rocket navigation systems) and 3D movie production (such as camera-type attitude tracking equipment for film and television), etc. Most of these products have complex structures, large sizes, and relatively low cost. High, it is almost impossible to achieve posture tracking suitable for the human body. In recent years, microcomputer systems with low power consumption and small size have ...
