[0002] Motion capture is to set trackers on the key parts of moving objects, which means the same as: Motion capture in English, Mocap for short. The technology involves data that can be directly understood and processed by computers in terms of size measurement, positioning and orientation of objects in physical space. Motion capture devices are now needed in many fields, but there are fewer monitoring modes and certain errors. Therefore, a multi-mode monitoring hand motion capture device is needed.

[0003] The defects of existing hand motion capture devices are:

[0004] 1. Existing hand motion capture devices have few monitoring modes for finger bending, finger opening, wrist bending and palm bending, and have certain errors, which is very inconvenient;

[0005] 2. The existing hand motion capture device is not convenient for workers to obtain the spatial position of the hand. For this reason, we propose a multi-mode monitoring hand motion capture device to solve the existing problem. Summary of the invention

[0006] The purpose of the present invention is to provide a hand motion capture device for multi-mode monitoring to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a multi-mode monitoring hand motion capture device, comprising a first insulating layer, a second insulating layer and a placement box, a second insulating layer is arranged on the inner side of the first insulating layer, and a first conductive rubber, a second conductive rubber and a third conductive rubber are arranged between the second insulating layer and the first insulating layer, a fourth conductive rubber is arranged between the first insulating layers, an electromyographic sensor is arranged on the inner side of the second insulating layer, and a detection electrode is arranged on the inner side of the electromyographic sensor, a placement box is fixedly installed at the bottom of the surface of the first insulating layer, and a rotating cover is movably installed on one side of the surface of the placement box, a battery is arranged inside the placement box, an inertial sensor is arranged inside the placement box on one side of the battery, a gyroscope is arranged inside the placement box at the bottom of the inertial sensor, an accelerometer is arranged inside the inertial sensor at the bottom of the gyroscope, a Bluetooth transmission module is arranged inside the placement box on one side of the accelerometer, and a data acquisition and processing module is arranged inside the placement box on the top of the Bluetooth transmission module.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention provides a first conductive rubber, a second conductive rubber and a third conductive rubber between the second insulating layer and the first insulating layer, a fourth conductive rubber is provided between the first insulating layer, and an electromyographic sensor is provided on the inner side of the second insulating layer. When using the device, the staff can wear the device on their hands, and the first conductive rubber will be attached to the finger through the second insulating layer. When the finger is bent, the first conductive rubber will cause a change in resistance due to stretching. Under the same voltage, the corresponding change in current can be detected, so that the degree of bending of the first conductive rubber can be measured. The second conductive rubber will be attached to the back of the hand through the second insulating layer.

The fourth conductive rubber is set between the fingers. When the palm is opened, the fourth conductive rubber will change its resistance due to stretching. Under the same voltage, the corresponding change of current can be detected, so as to measure the stretching degree of the fourth conductive rubber. Thus, the bending of each finger, the bending of the palm, the bending of the wrist, and the opening of the palm can be calculated, and then the movement state of the whole hand can be obtained. By setting multiple detection electrodes in the innermost layer and connecting the electromyographic sensor to detect the muscle contraction, the algorithm can be assisted to locate the hand movement more accurately.
