1. A wearable motion capture glove based on a flexible optical fiber, the wearable motion capture glove comprising a glove body, a plurality of motion acquisition and sensing devices, and a glove packaging tool, wherein each motion acquisition and sensing device individually comprises a data acquisition and processing module, a circuit splint, and a flexible polymer profiled optical fiber;
the data acquisition and processing module comprises a motion capture data acquisition module, and a motion capture data processing module; the motion capture data acquisition module comprises a front laser emitting board, a central laser receiving and emitting board, and a rear laser receiving board; the circuit splint comprises a front circuit splint, a central circuit splint, and a rear circuit splint; the flexible polymer profiled optical fiber comprises a first flexible polymer profiled optical fiber, and a second flexible polymer profiled optical fiber;
one end of the first flexible polymer profiled optical fiber is connected to the front laser emitting board, and the other end of the first flexible polymer profiled optical fiber is connected to a laser receiving end of the central laser receiving and emitting board; one end of the second flexible polymer profiled optical fiber is connected to a laser emitting end of the central laser receiving and emitting board, and the other end of the second flexible polymer profiled optical fiber is connected to the rear laser receiving board;
the front circuit splint is used to fixedly connect one end of the first flexible polymer profiled optical fiber to the front laser emitting board in a pressing way, and is fixed to a middle phalanx position of the glove body after being packaged by the glove packaging tool; the central circuit splint is used to fixedly connect the other end of the first flexible polymer profiled optical fiber, the central laser receiving and emitting board and one end of the second flexible polymer profiled optical fiber in a pressing way, and is fixed to a proximal phalanx position of the glove body after being packaged by the glove packaging tool; and the rear circuit splint is used to fixedly connect the other end of the second flexible polymer profiled optical fiber to the rear laser receiving board in a pressing way, and is fixed to a proximal metacarpal head position of metacarpal phalanx of the glove body after being packaged by the glove packaging tool;
the motion capture data processing module is connected to the motion capture data acquisition module; the motion capture data acquisition module is used to convert an optical signal representing finger joint deformation information into a voltage signal and transmit the voltage signal to the motion capture data processing module; and the motion capture data processing module is used to process the voltage signal and transmit the processed voltage signal to an upper computer.
