Embodiment Construction
[0028] The present invention is a kind of amputation upper limb rehabilitation training system based on virtual reality, such as figure 1 As shown, the system includes the EMG signal detection and processing part, the amputated upper limb modeling part, and the virtual reality scene interaction part, among which:
[0029] The myoelectric signal detection and processing part extracts, amplifies, filters, A / D converts and multi-channel acquires the surface myoelectric signal of the patient's residual limb, so as to obtain the myoelectric signal of the patient's hand;
[0030] The amputee upper limb modeling part utilizes photos of healthy upper limbs, uses a 3D parametric grid model to perform 3D reconstruction of the amputee upper limbs, uses the patient's hand myoelectric signal as the model-driven data, and realizes the movement simulation of the virtual hand;
[0031] The virtual reality scene interaction part models the real three-dimensional interactive scene, and realizes...
