It should be explained that in this document, we regard the knuckle closest to the fingertip as the first knuckle and the knuckle adjacent to the first knuckle as the second knuckle. In addition, the light emitting device 2 and the glove body 1 may be connected by an adhesive.
The processing unit 4 is arranged on the wrist part 12 and is positioned on one side of the palm of the glove body 1. Specifically, the processing unit 4 is a single chip or a central processing unit with image analysis and processing capabilities, and the processing unit 4 may be connected to the wrist portion 12 of the glove body 1 through an adhesive. In addition, the processing unit 4 is electrically connected to the 14 light emitting devices 2 through wires built in the glove body 1.
The camera unit 3 is located on one side of the palm of the glove body 1, and a lens of the camera unit 3 faces one side of the five finger parts. Specifically, the imaging unit 3 may be a high-performance CMOS camera. The camera unit 3 is electrically connected to the processing unit 4 and directly mounted on one side of the processing unit 4 facing the five finger portions, so that the lens of the camera unit 3 can shoot and record 14 light emitting devices 2 arranged on the five finger portions.
In an operating state, a user of the camera unit 3 shoots and records dynamic images of 14 light emitting devices 2, and the processing unit 4 receives and obtains a position change track of each light emitting device 2 according to the dynamic images.
The following describes a method of using the finger bending degree detecting device to measure the degree of bending of a user's finger. The method comprises the following steps:
1) wearing a finger bending degree detection device (see fig. 2);
2) the processing unit 4 controls the camera unit 3 to start;
3) the processing unit 4 controls the plurality of light emitting devices 2 to light up in sequence, and indexes the plurality of light emitting devices 2 according to the sequence of the plurality of light emitting devices 2 to light up;
4) the glove body 1 moves under the operation of wearing;
5) the camera unit 3 shoots a plurality of dynamic images formed by the light-emitting devices 2 along with the movement of the glove body 1;
6) the processing unit 4 receives and obtains the position change track of each light emitting device 2 according to the dynamic image, and sends the position change track to a computer with data analysis and processing capability in a wired or wireless mode. Finally, the bending degree of the fingers of the user is obtained through the computer.
In summary, with the finger bending degree detection apparatus, after the user wears the glove body 1, the fingers of the user will drive the five fingers of the glove body 1 to move, the light emitting devices 2 disposed on the five fingers will also move, the camera unit 3 can record a dynamic image of each light emitting device 2, and the processing unit 4 receives and obtains a position change trajectory of each light emitting device 2 according to the dynamic image. Subsequently, the processing unit 4 can transmit the position change trajectory to a computer which then has data analysis processing capability, so as to derive the degree of bending of the user's finger. Since the image capturing unit 3 can capture the fine movement of the light emitting device 2 in real time, the method of capturing the dynamic image of the light emitting device 2 by the image capturing unit 3 to obtain the bending change of the finger of the user is more accurate and can capture the fine bending motion of the finger of the user than the method of obtaining the bending change of the finger of the user by the bending sensor in the prior art.
It is mentioned that the above measurement process may further include the following steps: the processing unit 4 controls the plurality of light emitting devices 2 which disappear after the shooting range of the shooting unit 3 and are shot by the shooting unit 3 again to sequentially flash. In this way, when the light emitting device 2 is blocked during the measurement process, and the light emitting device 2 disappears in the picture captured by the camera unit 3, the light emitting devices 2 re-entering the captured picture of the camera unit 3 sequentially flash under the control of the processing unit 4, so as to confirm the index information of each light emitting device 2 and prevent confusion.
In order to ensure that the image capturing unit 3 can effectively distinguish two light emitting devices 2 in the same finger stall, which are close to each other, during the measurement process, in this embodiment, the light emitting devices 2 in the small finger stall 131, which are respectively located on the upper side of the second joint of the small finger stall 131 and the lower side of the second joint of the small finger stall 131, have different light emitting colors; the 2 light-emitting devices 2 on the ring finger cot 132, which are respectively positioned on the upper side of the second joint of the ring finger cot 132 and the lower side of the second joint of the ring finger cot 132, have different light-emitting colors; the 2 light-emitting devices 2 on the middle finger sleeve 133, which are respectively positioned on the upper side of the second joint of the middle finger sleeve 133 and the lower side of the second joint of the middle finger sleeve 133, have different light-emitting colors; the 2 light emitting devices 2 on the index finger sleeve 134 are respectively positioned on the upper side of the second joint of the index finger sleeve 134 and the lower side of the second joint of the index finger sleeve 134, and the light emitting colors of the light emitting devices are different. Specifically, the light emitting device 2 on the upper side of the second joint on each finger cuff is set to green in color, and the light emitting device 2 on the lower side of the second joint is set to red in color.
In order to ensure that the image capturing unit 3 can effectively measure the fingertip positions with the largest moving ranges of the small finger cuff 131, the ring finger cuff 132, the middle finger cuff 133, the index finger cuff 134, and the thumb cuff 135.
