Description
Technical field
The utility model relates to realize that three-dimension gesture detection identification field more particularly to a kind of 3D are red using infrared sensor
Outer hand gesture detecting device.
Background technique
With the application and development of smart home, intelligent monitor, the wearable, VR of intelligence etc., gesture identification is as man-machine friendship
Mutual important component, research and development affect the naturality and flexibility of human-computer interaction.
People have studied various gestures recognition methods and technology at present, wherein using infrared signal be exactly it is one such,
Also commercialized product generates, such as leap motion, but from current application, infrared Gesture Recognition and device,
It often there is problems (characteristic):
(1) it applies in the gesture identification of some low costs with device, on the one hand can only often carry out the inspection of two-dimentional gesture
It surveys, then there is detecting distance on the other hand and fix, it is difficult to which appropriate adjusting is carried out according to different application；
(2) current most researchers are primarily focused on the final identification aspect of gesture, it will usually carry on the back gesture
Scape simplifies, but in practical application, gesture is generally under complex environment, such as: light is excessive lightness or darkness, has more gesture
In the presence of away from acquisition equipment apart from the various complex background factors such as different, therefore generally require carry out appropriateness ambient compensation.
Summary of the invention
In order to solve the above technical problems, the purpose of the utility model is to provide a kind of infrared hand gesture detecting device of 3D, the dress
It sets and can be used for the fields such as wearable smart home, intelligent monitor, intelligence, VR, game application, realize the adjusting of detecting distance,
Infrared signal and visible light compensation.
The purpose of this utility model is realized by technical solution below:
A kind of infrared hand gesture detecting device of 3D, comprising:
Infrared transmitter (1-5), infrared compensator (6), infrared remote receiver (7), visible light sensor (9), left pcb board
(8), right pcb board (11) and rectangle PCB bottom plate (13)；
There are five the infrared transmitter includes, wherein four infrared transmitters are separately positioned on left pcb board (8), right PCB
On four angles of plate (11), one of infrared transmitter is arranged at the center of rectangle PCB bottom plate (13)；
The infrared compensator (6), infrared remote receiver (7) and visible light sensor (9) are separately positioned on rectangle PCB bottom plate
(13) center.
Compared with prior art, one or more embodiments of the utility model can have following advantage:
For fields such as smart home, intelligent monitor, intelligent wearable, VR, game applications, one can be realized by the present apparatus
The infrared gesture identification of three-dimensional of kind of low cost, the infrared hand gesture detecting device may be implemented gestures detection apart from adjustable, infrared and
The functions such as visible light compensation.
Detailed description of the invention
Fig. 1 is the infrared hand gesture detecting device overlooking structure figure of 3D；
Fig. 2 is the infrared hand gesture detecting device sectional view of 3D；
Fig. 3 a, 3b and 3c are the infrared hand gesture detecting device detection range schematic diagrames of 3D.
Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, below in conjunction with examples and drawings pair
The utility model embodiment is described in further detail.
As depicted in figs. 1 and 2, the infrared hand gesture detecting device structure of 3D is illustrated, comprising: infrared transmitter 1-5, infrared benefit
Repay device 6, infrared remote receiver 7, visible light sensor 9, left pcb board 8, right pcb board 11 and rectangle PCB bottom plate 13；
There are five the infrared transmitter includes, wherein four infrared transmitters are separately positioned on left and right pcb board 8 and 11
Four angles on, the center of rectangle PCB bottom plate 13 is arranged in one of infrared transmitter；
The infrared compensator 6, infrared remote receiver 7 and visible light sensor 9 are separately positioned in rectangle PCB bottom plate 13
Heart position.
The left pcb board 8, right pcb board 11 are separately positioned on the right and left on rectangle PCB bottom plate 13；
Infrared transmitter positioned at 13 center of rectangle PCB bottom plate is the infrared gestures detection datum mark of 3D.It, can when position correction
Hand is hovered over to the origin reference location that position is used for right above it.
Gestures direction and proximity test may be implemented by above-mentioned infrared transmitter and infrared remote receiver, and then realize three-dimensional
The detection of gesture, for example when hand is brandished from left to right, the detection object of infrared discharge lamps 2 and 3 can be first determined, then infrared hair
Shot-light 1 is finally that infrared discharge lamps 4,5 detect object, and then tell the direction of gesture.Other orientation principles are similar, lead to
Crossing different reception signals may determine that the gesture of different directions；And the proximity test of hand then can be received by infrared remote receiver
Signal strength is judged.
It is adjustable that by bolt infrared emission tube spacing three-level may be implemented in above-mentioned left pcb board and right pcb board, and then makes infrared
Gestures detection distance can be adjusted between three different range, and three detection range Z are as shown in Figure 3a, 3b and 3c as shown in.
The left pcb board 8 and right pcb board 11 are connect by 10 screw hole 12 of stud, nut 14 with rectangle PCB bottom plate solid respectively
It is fixed, and the circuit of left pcb board 8, right pcb board 11 is connect with rectangle PCB bottom plate 13 by winding displacement.
Above-mentioned infrared compensator and visible light sensor are for realizing to infrared signal, visible light compensation.
The phase of above-mentioned infrared compensator 6 is opposite with infrared transmitter 1-5's.
Although embodiment disclosed by the utility model is as above, the content is only to facilitate understand that this is practical
Novel and use embodiment, is not intended to limit the utility model.Skill in any the utility model technical field
Art personnel can be in the formal and details of implementation under the premise of not departing from spirit and scope disclosed by the utility model
On make any modification and variation, but the scope of patent protection of the utility model, must still be defined with appended claims
Range subject to.
