Description
Technical Field
The invention relates to a glove, in particular to a glove based on an electromagnetic field motion capture technology.
Background
At present, four modes of optical mode, acceleration sensor mode, time domain microwave mode and electromagnetic field mode are mainly adopted for human body motion extraction.
The first optical mode adopts visible light or infrared rays to carry out image recognition and tracking on the beacons of the joint parts of the human body, so that human body motion extraction is realized, and the defects are that the beacons are possibly shielded, motion omission is generated, in addition, the image processing speed is lower, and the cost is generally higher; this technique is also used for glove applications such as the production of facebook.
The second acceleration sensor method is used for calculating the relative position of each joint by the acceleration of human body action, and has the defects of being capable of only obtaining the position information of the relative previous position, high in cost and inconvenient to use due to the fact that timing calibration is needed, and the method is only suitable for industrial applications such as film making; the technology has a series of dynamic fishing gloves for glove-like products.
The third time domain microwave mode adopts a method for calculating the propagation delay of signals reaching different receivers to extract the position of the beacon, and has the defects that the antenna is large in volume and is not suitable for being distributed at a plurality of positions on a human body; the person is required to be in a specific space where the receiver is installed, and the accuracy is low, and the cost of high-accuracy positioning (in cm) is high. The technology is not suitable for human body limb motion capture and is only used for large-space multi-player game positioning. The method is mainly used for inventory tracking and positioning and logistics management at present.
The fourth electromagnetic field analysis mode is divided into two types, the first type is a mode of generating a fluctuation field by combining a direct current magnetic field and an alternating electric field, and the mode is easy to be interfered by metal in a measurement area due to the use of a direct current static field; the second type adopts a complex 3-way orthogonal 3-frequency antenna group receiving and transmitting system, the 3-way orthogonal antenna group transmits signals with one frequency respectively, the receiving end also adopts the 3-way orthogonal antenna to independently receive, the positions on three coordinate axes are respectively solved, and the distance and the included angle between the receiving antenna and the transmitting antenna on the whole are calculated. The system has strong anti-interference capability, but has complex structure, complex calculation parameter extraction and very high price, generally needs hundreds of thousands or hundreds of thousands, and cannot be used for common entertainment. Both of these approaches have in common that the transmitting antenna is placed at a certain location independent of the person being tracked and the receiving antenna is placed as a beacon around the body of the person being tracked. Therefore, the user must be located within a certain range of the position of the transmitting antenna and cannot move randomly. Actual products such as the product line of Boersham Mo Sigong.
Disclosure of Invention
The invention aims to provide a glove based on an electromagnetic field motion capture technology, which solves the problem that the traditional electromagnetic field analysis motion capture glove needs to be assisted by externally installing other equipment and a user can only move within a certain range.
The invention is realized by the following technical scheme:
the glove based on the electromagnetic field motion capture technology comprises a glove body and further comprises a connector arranged on the glove, wherein the connector is connected with at least one large electromagnetic field sensor arranged on the palm part of the glove and a plurality of small electromagnetic field sensors arranged on the finger part of the glove. The electromagnetic field sensor adopts a close-range electromagnetic field radiator, the radiator can generate electromagnetic field fields with the action distance of 1 meter and the radiation component precision of 1-2cm in different frequency ranges, and meanwhile, the radiator can receive signals in the electromagnetic field of other radiators, and the distance between the radiator and corresponding equipment is judged according to the frequency range of the radiation component of the signals. The glove judges the action of fingers through measuring and calculating the relative displacement of the small electromagnetic field sensor and the large electromagnetic field sensor, judges the action of the palm through measuring and calculating the large electromagnetic field sensor and the electromagnetic field sensor arranged on the trunk, and does not need to be provided with other equipment outside.
The plug connector is packaged in a waterproof bag subjected to watertight treatment. The plug connector is arranged in the waterproof bag which is subjected to watertight treatment, and when the glove is required to be washed, the waterproof bag is only required to be closed, so that the problem that the general motion capture equipment cannot be washed is solved.
The plug connector is connected with the large electromagnetic field sensor and the small electromagnetic field sensor through thin coaxial cables embedded in the glove. The thin coaxial cable is convenient to wire because the cable is used for the glove, and meanwhile, the coaxial cable is most matched with the product because the cable works in an electromagnetic field, the radiation loss of the coaxial cable is small and the influence of external interference is small.
The number of the large electromagnetic field sensors is two, one of the large electromagnetic field sensors is arranged on one surface of the palm of the glove, and the other large electromagnetic field sensor is arranged on one surface of the back of the hand of the glove. The two large electromagnetic field sensors are used, so that the problem that the system cannot work after one large electromagnetic field sensor is out of order can be avoided, and the accuracy of the system can be improved by measuring and calculating the movement of the small electromagnetic field sensor relative to the two large electromagnetic field sensors respectively.
The number of the small electromagnetic field sensors is five, and the five small electromagnetic field sensors are respectively arranged on fingertips of five fingers of the glove. Because the hand collecting actions are the actions of collecting fingers, and almost all the actions of the fingers are reflected on the movement tracks of the fingertips, the small electromagnetic field sensor is arranged at the fingertips of the glove, so that the finger collecting movement tracks of the fingertips are convenient to collect and judge the actions of the fingers.
The number of the small electromagnetic field sensors is ten, and the ten small electromagnetic field sensors are respectively arranged at the fingertips and the finger roots of five fingers of the glove. The knuckle close to the palm is used as the first knuckle, and because of the special physiological structure of the hand of a person, most of the food fingers, middle fingers, ring fingers and little fingers of the person cannot enable the third knuckle to act under the condition that the second knuckle is static relative to the first knuckle, and meanwhile, the action of most of the fingers can be judged by detecting the action of the first knuckle relative to the palm and the movement of the third knuckle relative to the palm and the first knuckle, so that ten small electromagnetic field sensors are respectively arranged at fingertips and finger roots of five fingers of the glove.
The glove is made of one or more of DuPont, coodula, pure cotton and lycra elastic fiber materials in a blending way. The material is breathable and wear-resistant, and is suitable for being worn and used for a long time.
The large electromagnetic field sensor and the small electromagnetic field sensor are both packaged on the back side of the glove. Because the movements of the palm and the fingers are bent towards the palm direction generally, and the large electromagnetic field sensor and the small electromagnetic field sensor can not be bent, the large electromagnetic field sensor and the small electromagnetic field sensor are arranged on one side of the palm, which is not beneficial to the palm to perform the actions such as grabbing, holding and the like, so that the large electromagnetic field sensor and the small electromagnetic field sensor are packaged on the back side of the glove.
Compared with the prior art, the invention has the following advantages and beneficial effects:
1. the glove based on the electromagnetic field motion capture technology is based on the short-distance electromagnetic field radiator, has low cost and simple structure, and is convenient to popularize;
2. according to the glove based on the electromagnetic field motion capture technology, all devices prefabricated on the glove are watertight treated, so that washing is facilitated.

Detailed Description
For the purpose of making apparent the objects, technical solutions and advantages of the present invention, the present invention will be further described in detail with reference to the following examples and the accompanying drawings, wherein the exemplary embodiments of the present invention and the descriptions thereof are for illustrating the present invention only and are not to be construed as limiting the present invention.
Example 1
As shown in fig. 1 and 2, the glove based on the electromagnetic field motion capture technology comprises a glove body and further comprises a connector 4 arranged on the glove, wherein the connector 4 is connected with at least one large electromagnetic field sensor 1 arranged on the palm part of the glove and a plurality of small electromagnetic field sensors 2 arranged on the finger part of the glove. The diameter of the large electromagnetic field sensor 1 is 15-20mm, and the diameter of the small electromagnetic field sensor 2 is 8-12mm. The electromagnetic field sensor adopts a close-range electromagnetic field radiator, the radiator can generate electromagnetic field fields with the action distance of 1 meter and the radiation component precision of different frequency ranges of 1cm, and meanwhile, the radiator can receive signals of other electromagnetic field fields of the radiator, and the distance between the radiator and corresponding equipment is judged according to the frequency range of the signal radiation component. The glove judges the action of fingers through measuring and calculating the relative displacement of the small electromagnetic field sensor 2 and the large electromagnetic field sensor 1, judges the action of the palm through measuring and calculating the large electromagnetic field sensor 1 and the electromagnetic field sensor arranged on the trunk, and does not need to install other equipment outside. The plug connector 4 is packaged in the waterproof bag 3 which is subjected to watertight treatment. The plug connector is arranged in the waterproof bag 3 which is subjected to watertight treatment, when the glove is required to be washed, the waterproof bag 3 is only required to be closed, and the problem that common motion capture equipment cannot be washed is solved. The plug connector 4 is connected with the large electromagnetic field sensor 1 and the small electromagnetic field sensor 2 through a thin coaxial cable pre-buried in the glove. Because the cable is used for gloves, the thin coaxial cable is convenient to wire, and meanwhile, because the cable works in an electromagnetic field, the coaxial cable has small radiation loss and is little influenced by external interference, and the coaxial cable is matched with the product most. The glove is made of DuPont, coodula, pure cotton and lycra elastic fiber materials in a blending mode. The material is breathable and wear-resistant, and is suitable for being worn and used for a long time. The number of the small electromagnetic field sensors 2 is five, and the five small electromagnetic field sensors 2 are respectively arranged on fingertips of five fingers of the glove. Since the hand collecting actions are the actions of collecting fingers, and almost all the actions of the fingers are reflected on the motion tracks of the fingertips, the small electromagnetic field sensor 2 is arranged at the fingertips of the glove, so that the finger collecting motion tracks are convenient to collect and judge the actions of the fingers. The large electromagnetic field sensor 1 and the small electromagnetic field sensor 2 are both packaged on the back side of the glove. Since the movements of the palm and the fingers are generally bent toward the palm direction, and neither the large electromagnetic field sensor 1 nor the small electromagnetic field sensor 2 can be bent, the large electromagnetic field sensor 1 and the small electromagnetic field sensor 2 are arranged on the palm side, which is unfavorable for the palm to perform the actions such as grasping, and the like, so that the large electromagnetic field sensor 1 and the small electromagnetic field sensor 2 are packaged on the back side of the glove.
Example 2
This embodiment differs from embodiment 1 only in that: the number of the large electromagnetic field sensors 1 is two, one of the large electromagnetic field sensors is arranged on one surface of the palm of the glove, and the other large electromagnetic field sensor is arranged on one surface of the back of the hand of the glove. The use of two large electromagnetic field sensors 1 can avoid the system from being inoperable after the problem of one large electromagnetic field sensor 1, and can improve the precision of the system by respectively measuring and calculating the movement of the small electromagnetic field sensor 2 relative to the two large electromagnetic field sensors 1.
Example 3
This embodiment differs from embodiment 1 only in that: the number of the small electromagnetic field sensors 2 is ten, and the ten small electromagnetic field sensors 2 are respectively arranged at the fingertips and the finger roots of five fingers of the glove. The knuckle close to the palm is used as the first knuckle, and because of the special physiological structure of the hand of a person, most of index finger, middle finger, ring finger and little finger of the person cannot enable the third knuckle to act under the condition that the second knuckle is static relative to the first knuckle, and meanwhile, the action of most of fingers can be judged by detecting the action of the first knuckle relative to the palm and the movement of the third knuckle relative to the palm and the first knuckle, so that the accurate measurement of the finger action can be completed by respectively installing ten small electromagnetic field sensors 2 at fingertips and finger roots of five fingers of a glove.
The foregoing description of the embodiments provides further details of the present invention with regard to its objects, technical solutions and advantages, and it should be understood that the foregoing description is only illustrative of the embodiments of the present invention and is not intended to limit the scope of the present invention, but any modifications, equivalents, improvements or etc. within the spirit and principles of the present invention should be included in the scope of the present invention.
