As shown in Figure 3, the concrete workflow of the utility model is:
Step S1, finish when the body identification control device based on depth detection is connected with relevant device, energized, open switch after, the pulse oscillating device produces the interrupting pulse ripple that comprises specific coding; Send transducer and accept this interrupting pulse ripple and be converted to ultrasound wave, this transmissions transducer emission has the ultrasound wave narrow beam of certain limit restriction, and this ultrasonic beam arrives all objects in the narrow beam scope according to certain frequency emission.At this moment, the user be provided with will paired domination number according to the body part that exerts an influence, can be hand, head, shank or the like, or whole body.
Step S2, be sent out the object that interrupted ultrasound examination that transducer launches arrives and reflect this wave beam, the direction of propagation of wave beam is opposite with the direction of illumination of ultrasonic beam, and be received transducer and receive, the far and near information of body surface and body identification control device distance is included in this reflected beam, and be converted into electric signal, be sent in the depth image module.
Step S3, depth reconstruction unit receive the electric signal that the switched-beam that captures from receiving transducer forms, and generate the depth image of all objects in this moment beam area thus.
Step S4, Target Recognition unit generate the depth image of all objects in this moment beam area according to depth reconstruction unit, discern and isolate the user set in advance will paired domination number according to the body part or the whole body that exert an influence.This unit can effectively filter out the part that sets in advance to the target health, and eliminates other objects and background to target health location influence.
Step S5, this target health of target localization cell location with based on the relative position of the body identification control device of depth detection and judge the attitude information of this target health, comprise inclination, rotation, folding or special distortion attitude.
The posture information of the target health that step S6, Date Conversion Unit obtain the target localization unit converts to according to this unit internal object health control rule of correspondence can be to data that will controlled respective application software control.This control data can be presented as the form of real goal health according to the difference of respective application software, perhaps is converted to control display format commonly used in the relevant device.
Step S7, data transmission unit comprise two kinds of transmission modes, and USB port is connected to relevant device and is transferred to relevant device by wireless bluetooth device; Date Conversion Unit obtain can to the data of respective application software control by data transmission unit be transferred to will controlled relevant device on.
The posture information that action comprised that step S8, user's target health is made is converted into the control data that can be discerned by respective application software fully, finally is presented on the projection screen.
Body identification control device based on depth detection of the present utility model, the interrupted ultrasound wave narrow beam that the certain limit restriction can be arranged by the ultrasonic sensor emission, and the object in the beam area all reflects this wave beam, reflected beam is received and generates in real time depth image, but the Target Recognition module can effectively be isolated paired domination number according to the body part or the whole body that exert an influence, target localization module and then discern the posture information of this part or whole body, and convert the data transmission that can control relevant device to relevant device.
To be applied to multimedia education field and game station field based on the body identification control device of depth detection, not only can bring the experience of controlling of efficiently and accurately, to audience's a kind of educational mode of teaching through lively activities more of also can yet be regarded as for the speaker; And this device that can make the player highly incorporate the recreation atmosphere makes that controlling of recreation is more direct.
As educator or speaker, certainly wish in the process of teaching or demonstrating, many and the audience's interaction of energy, low coverage is liftoff to contact the audience so that obtain audience's reaction more intuitively, be easier to like this improve the mode and the process of teaching or giving a lecture, make the audience think that intricate content becomes simple.The control mode of ancient teacher's pointer and conventional mouse keyboard firmly is locked in the front of demonstration equipment to the speaker, has significantly reduced the probability of speaker and audience's interaction.And develop gradually such as electronic teacher pointer, data glove etc. can cause long-time hand-held muscular tone to perspire again, the influence operation, again or wear trouble, the problem that user's comfort level is not high.Use is based on the body identification control device of depth detection, by the depth image in the interrupted ultrasound wave narrow beam of the real-time generation scope, accurately but the identification paired domination number is according to the body part or the whole body that exert an influence, this in the speech process, the speaker need be not a nature accurate controlling equipment again by any external unit mode fully.The speaker only needs to be provided with some to own gesture or attitude easy to use before use equipment, in the speech process, as long as be in the body identification control device beam area, a simple action just can be controlled calmly, and needn't worry because apart from equipment too long-range guided missile cause and can't carry out next link.
This equipment is for the audience, also easier their notice of quick attraction, and do not had to knock keyboard or rocked the thing that telepilot etc. interrupts speech, the speaker always is in and carries out interaction between the audience, just can control also more attractive of such speech concerning the audience to equipment such as the action of simply waving.
And based on the body identification control device of depth detection when being applied to the game station field, the control mode of its efficiently and accurately, player's both hands can both be discharged, the action or the form of personage and device in the imitation recreation farthest from traditional game paddle and keyboard.This makes that the interest of recreation is stronger, and this game mode makes the player also take into account movable health in amusement simultaneously.
New-typely control experience for what the user had brought fast and flexible in use based on the body identification control device of depth detection, this is not only to have surmounted traditional teacher's pointer or telepilot on degree of accuracy and comfort level, more the user brings unprecedented smooth experience, makes that operating single demonstration speech and recreation originally becomes an interesting activity.
Body identification control device based on depth detection described in the utility model, be not restricted to listed utilization in instructions and the embodiment, it can be applied to the field of various suitable the utility model fully, for those skilled in the art, can be easy to realize additional advantage and make amendment, therefore under the situation of the spirit and scope of the universal that does not deviate from claim and equivalency range and limited, the utility model is not limited to specific details, representational equipment and the examples shown that illustrates here and describe.
The above; it only is the preferable embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
