Embodiment Construction
[0030] figure 1 It is a physiological and mechanical model of the human body. Based on this model, the human body can be divided into 15 independent limbs, and each limb has six degrees of freedom in three-dimensional space. Each limb can thus be tracked in three dimensions using an inertial measurement unit with six degrees of freedom.
[0031] Figure II It is a system architecture diagram based on a wireless wearable sensor network. A human body motion tracking system based on ZigBee / IEEE 802.15.4 consists of a wearable wireless sensor node, a wireless wearable sensor network, a base station (or a gateway, and the book is marked with a gateway) , this paper calls it the base station) and the distribution network consists of four parts. The wireless wearable node is used to monitor the movement of each independent limb in three-dimensional space; the wireless wearable sensor network is used to monitor the whole human body movement; the base station is used to receive real-...
