Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
The embodiment of the invention is responded to based on infrared image; Through obtaining the relevant information of depth image; User's limbs are separated from the complex environment background, and user's limb action is discerned and commands match, thereby reach the purpose of not using traditional remote controller control television set.
Fig. 1 shows the internal structure of the RTV remote television that the embodiment of the invention provides, and for the ease of explanation, only shows the part relevant with present embodiment.
With reference to Fig. 1, this RTV remote television comprises:
Depth image sensing unit 11 is responded to the depth image of user's limbs, to obtain the picture depth data.Wherein, depth image sensing unit 11 also comprises:
Infrared structure Optical Transmit Unit 111, it is positioned at the dead ahead of TV set panel, is responsible for to the infrared structure optical plane of television set dead ahead emission through coding.
Infrared structure light sensing unit 112, it is positioned at the dead ahead of TV set panel, is responsible for receiving the infrared structure light of returning via television set dead ahead reflection object.
In embodiments of the present invention; The reflective infrared structured light that depth image sensing unit 11 receives through induction infrared structure light sensing unit 112; According to the structure light coding know-why; Through the structure light coding of contrast three-dimensional environment object and the structure light coding of original plane, thereby obtain the depth data of each pixel of sensed image, comprise distance and the variable in distance thereof of each pixel with respect to inductor.
Limb action recognition unit 12 according to the picture depth data of obtaining in the depth image sensing unit 11, is discerned user's limb action.Wherein, limb action recognition unit 12 also comprises:
Limbs profile recognition unit 121 is responsible for from environmental background, identifying the limbs profile that the user carries out remote control.
In embodiments of the present invention; Because with respect to other environmental backgrounds in television set dead ahead, the user is in the process of practical operation remote control, its limb part moves; Can the mode of user profile through image difference be identified; Therefore further, can the hand profile that the user carries out remote control be identified through limbs profile recognition unit 121, for example user's hand profile.
Limb action judging unit 122 through the limbs profile that the user who identifies in the tracking limbs profile recognition unit 121 carries out remote control, is judged user's limb action type.
In embodiments of the present invention; Can be through detecting original position, movement locus and the final position that the user carries out the limbs profile of remote control; Judge user's limb action type; In embodiments of the present invention, user's limb action type can not limit at this for action and combination of actions thereof such as waving back and forth fast, wave left, wave to the right.
In embodiments of the present invention, therefore a kind of television set control command that each of user type limb action is all corresponding can detect the television set control command of this limb action representative through induction user's limb action.
As realization example of the present invention, the corresponding relation of user's limb action and television set control command can be following:
Wave fast, promptly in the setting-up time threshold value, user's one hand health the place ahead do by a small margin fast about the action of waving, correspond to the order of ON/OFF television set.
Wave fast left, promptly in the setting-up time threshold value, user's one hand is done the action of brandishing that surpasses the setpoint distance threshold value from right to left in health the place ahead, corresponds to a last channel control command of TV function identification.
Wave fast to the right, promptly in the setting-up time threshold value, user's one hand is done the action of brandishing that surpasses the setpoint distance threshold value from left to right in health the place ahead, corresponds to the next channel control command of TV function identification.
Thorny clockwise, promptly user's one hand according to clockwise direction, is done loop around action in health the place ahead, corresponds to the increase volume control command of TV function identification.
Thorny counterclockwise, promptly user's one hand according to clockwise direction, is done loop around action in health the place ahead, corresponds to the volume control command that reduces of TV function identification.
In embodiments of the present invention, user's the limb action type and the corresponding relation of television set control command can be not limited to above-mentioned realization example, do not limit at this.
Fig. 2 shows the workflow of the remote-controlled television set that the embodiment of the invention provides, and details are as follows:
In step S201, emission is through the infrared structure optical plane of coding.
In step S202, receive the infrared structure light of returning via television set dead ahead reflection object, obtain depth image.
In embodiments of the present invention; Through the infrared structure optical plane of infrared structure Optical Transmit Unit 111 to television set dead ahead emission process coding; It just reflects after in emission process, running into object; Infrared structure light through 112 pairs of infrared structure light sensing units reflect is responded to, and obtains the depth image of television set dead ahead scene
In step S203, the depth image that obtains is responded to, obtain the picture depth data.
In embodiments of the present invention; According to the structure light coding know-why; Through the structure light coding of contrast three-dimensional environment object and the structure light coding of original plane, thereby obtain the depth data of each pixel of sensed image, comprise distance and the variable in distance thereof of each pixel with respect to inductor.
In step S204,, identify the limbs profile that the user carries out remote control according to the picture depth data.
In step S205, the limbs profile that the user who goes out through Tracking Recognition carries out remote control is judged user's limb action type.
In embodiments of the present invention; Because with respect to other environmental backgrounds in television set dead ahead, the user is in the process of practical operation remote control, its limb part moves; Can the mode of user profile through image difference be identified; Therefore further, can the hand profile that the user carries out remote control be identified through limbs profile recognition unit 121, for example user's hand profile.Through detecting original position, movement locus and the final position that the user carries out the limbs profile of remote control, judge user's limb action type thus.
In step S206, the limb action type conversion of judging the user is the corresponding TV set control command and carries out.
In embodiments of the present invention; Therefore a kind of television set control command that each of user type limb action is all corresponding can detect the television set control command of this limb action representative through induction user's limb action; And the execution control command, reach the purpose of remote-controlled television set.
In embodiments of the present invention; Infrared structure light through reflected back obtains depth image information; Thereby user's limbs profile is separated from the complex environment background, discerned user's limb action fast and mate, do not use traditional remote controller to control the purpose of television set thereby reach with the corresponding TV set control command; Avoid ambient light effects effectively, be implemented in the stable use under the various illumination conditions.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
