The telepilot control method of gesture control of the present invention is divided into gesture location (Location), clicks (Click), slides (Slide) and cancellation (Cancel).Below will explain in detail one by one:
1. locate: the telepilot control method of gesture control of the present invention will have the electronic installation (for example televisor) of screen display function, and default start back actions menu in off position.At first the user with both hands about flat act brandish up and down, this user's optimum operation position (as shown in Figure 5) is located in meeting of the present invention this moment automatically, and starts on the display picture of electronic installation (for example televisor) that the entree chief of the Xiongnu in Acient China should have screen display function.The operating position of virtual touch-control key lay respectively at this user's head directly over, both sides, two outsides and right-hand man position (as shown in Figure 6).Directly over this user's head, both sides, two outsides are the function selecting district; The left side virtual key of right-hand man position and right side virtual key are then for switching (rotation) menu or sending function key.
2. click: directly over above-mentioned this user's head, the function selecting district in both sides, two outsides is suitable for and clicks gesture.Finish selection when this user's hand is upwards touched the virtual touch-control key in this function selecting district, touching is once then removed again, is called alternative expression (Toggle) button.And when this user touches the virtual touch-control key in another this function selecting district, can automatically terminate the function of the virtual touch-control key in this function selecting district at present.That is to say can only have the virtual touch-control key in this function selecting district selected at most simultaneously, is called radio formula button (Radio Button).
3. slide: above-mentioned this left side virtual key and this right side virtual key are suitable for the slip gesture.This right side virtual key is only supported the gesture of brandishing to the right, and the gesture of other direction can not moved; This left side virtual key is only supported the gesture of brandishing left, and the gesture of other direction can not moved.When directly over this user's head, the function selecting district in both sides, two outsides all do not have when selected, this user's hand is brandished then can switch (rotation) menu content; When directly over user's head, the function selecting district in both sides, two outsides has when selected, this user's hand is brandished expression to the right and is sent the positive function key, then sends negative function key otherwise brandish left.Be adjusted into example with volume, when volume adjustment function was selected, this user's hand was brandished to the right and volume can be transferred greatly, brandishes left and volume can be turned down.Above-mentioned this user's hand is brandished expression to the right and is sent the positive function key, brandishes left and then sends the negative function key, but not as limit, and the hand that also can be set at this user is brandished expression left and sent the positive function key, sends negative function key and brandish to the right.
4. cancellation: cancellation gesture (as shown in Figure 7) swings to front raise for both hands, as getting back to the last layer menu or closing menu and use.
The described menu of telepilot control method of gesture control of the present invention is divided into master menu (MainMenu) and submenu (Sub Menu).This master menu is mainly used in and switches controlled electronic device project and default option.As previously mentioned, user's hand is brandished promptly changeable (rotation) job about this left side virtual key and this right side virtual key.The project of the i.e. desire operation in zone, user's above-head center is as televisor, DVD, air conditioner, set-top box or the like.Can enter the submenu of this project after the click.As desire to close this master menu, get final product end operation with the cancellation gesture.After entering submenu, can click selection of functional areas, top or cancellation job.User's hand is brandished switching (rotation) job (if the functional areas, top are not selected) about this left side virtual key and this right side virtual key, as volume, channel, color or the like, or send forward and reverse function key (if the functional areas, top are selected), can get back to master menu (as shown in Figure 8) with the cancellation gesture.
In the time will changing other user and operate, after former user must finish master menu earlier, change again another user with both hands about flat act brandish up and down, make the location gesture.Can only there be user's operation the same time, and the user can not exceed the visual range of camera model.
Please refer to Fig. 1, it is the telepilot control method process flow diagram of gesture control of the present invention.The telepilot control method of gesture control of the present invention is by detecting user's gesture to control a controlled electronic device.This controlled electronic device is televisor, DVD player, air conditioner or computing machine an or the like electronic installation.At first step S10 detects this user's image, utilizes a camera model to realize.Then step S20 adjusts this user's image and adjusts image to obtain one.The step S30 that continues does difference processing to this adjustment image and adjusts motion image to obtain one.Step S40 detects this adjustment motion image to obtain a momentum image then.Then step S50 defines a momentum zone to this momentum image.The step S60 that continues produces corresponding control signal according to the variation in this momentum zone.Final step S70 launches this control signal via a wireless launcher, to control this controlled electronic device.The telepilot control method of gesture control of the present invention will cooperate process flow diagram to describe in detail later.
Wherein, this step S20 (adjust this user's image and adjust image to obtain) comprises: the size of adjusting this user's image is for being fit to the calculation size, this user's image being carried out color conversion (for example reducing to GTG 8bit Gray Level by full-color 24bit RGB) and filtering point-like noise.The method of filtering point-like noise can be by image low-pass filter (Image Low Pass Filter).
Wherein, this step S30 (this adjustment image is done difference processing adjust motion image to obtain) utilizes the image Difference Calculation to come out.Please refer to Fig. 2, it is an image method of difference synoptic diagram.And be to try to achieve preferable result, utilize continuous three frame images to calculate this adjustment motion image at this.At first a present frame grey-tone image I2 is deducted a former frame grey-tone image I1, to obtain one first grey-tone image (not icon).After setting up one first GTG threshold value (First gray level threshold), this first grey-tone image is set at bright spot more than or equal to the part of this first GTG threshold value, part less than this first GTG threshold value then is made as dim spot, to obtain one first binaryzation image I3.Then this former frame grey-tone image I1 is deducted the first two frame grey-tone image I0, to obtain one second grey-tone image (not icon).After setting up one second GTG threshold value (Second gray level threshold), this second grey-tone image is set at bright spot more than or equal to the part of this second GTG threshold value, part less than this second GTG threshold value then is made as dim spot, to obtain one second binaryzation image I4.(AND) computing of at last this first binaryzation image I3 and this second binaryzation image I4 being occured simultaneously can obtain one the 3rd binaryzation image I5.The 3rd binaryzation image I5 is this adjustment motion image.Such purpose is in order to find out the gesture position of this user's motion.
This step S40 (detecting this adjustment motion image to obtain a momentum image) flow process below will be described in detail in detail.At first the 3rd binaryzation image I5 is divided into most blocks (as shown in Figure 3) of cutting apart.Judge according to a momentum threshold value (Movement Threshold) one this whether cut apart block be a momentum block.According to a preferred embodiment of the present invention, can be set at bright spot greater than this momentum threshold value (Movement Threshold); The mode that is set at dim spot less than this momentum threshold value (Movement Threshold) is reached.Bright spot is represented the momentum block, and dim spot is represented non-momentum block.For instance, being 160*120 with a pixel, image is cut into 16*12 part (promptly have 16*12 and cut apart block), each this cut apart block 100 pixels (because (160/16) * (120/12)=100) arranged; Suppose that this momentum threshold value (MovementThreshold) is located at 50, then cut apart momentum in the block and count statistics when surpassing this momentum threshold value (Movement Threshold) when one, then this is cut apart block and be made as a momentum block.After so disposing, can obtain this momentum image.The purpose of Chu Liing is trace to be moved and excessive moving filter falls like this, to reduce the probability of erroneous judgement.
This step S50 (this momentum image is defined a momentum zone) flow process below will be described in detail in detail.This define the coordinate range of this momentum zone in this momentum image for (LTX, LTY)～(RBX, RBY), as shown in Figure 4.With LTY is example, from top to bottom right by a left side, finds first this momentum block, and this is the upper limb in this momentum zone.Find out RBY, LTX and RBX by that analogy, can obtain lower edge, left border and the right border (as shown in Figure 4) in this momentum zone.Represent not have this momentum block or the too small actions menu that do not need of area when this momentum zone is (0,0)～(0,0), timing is promptly closed master menu or submenu after surpassing a setting value voluntarily.
As previously mentioned, the telepilot control method of gesture control of the present invention is divided into click, slip, location and cancellation with gesture.Wherein with irrelevant gesture of time for clicking gesture; Sequential type gesture is then as sliding, locate or the cancellation gesture.Be the clear gesture kind of differentiating, thus must the general recently several times momentum area coordinate and size note.When momentum zone with click defined range and represent to click gesture when overlapping and produce.Have in the momentum zone and to continue when assigned direction displacement (for example continuing transversal displacement, length travel or oblique as 45 degree angular displacements), then be judged to be one and adjust gesture (comprising increment or decrement key controlling command), wherein continue transversal displacement for continuing to left dislocation or continuing displacement to the right.Promptly continue to move right and increment (right button) when zone dropped in the position when the momentum zone has, the expression gesture of sliding to the right produces; Otherwise, continuing to be moved to the left and decrement (left button) when zone dropped in the position, the expression gesture of sliding left produces.When the momentum zone by middle zonule when horizontal big zone changes back and forth and is arranged in lower area (when having lasting widthwise size to change) in the momentum zone, expression cancellation gesture generation (as shown in Figure 7).When the momentum zone by the big zone of intermediate lateral to central longitudinal to big zone change back and forth (be the momentum zone have by laterally become vertically or by vertically becoming horizontal trend), expression location gesture produces (as shown in Figure 5).When excessive or longitudinal region connected up and down when momentum zone, the object that expressed possibility crossed very close to the camera model camera lens, belongs to undesired interference.The motion that other can't be differentiated or produce non-definition direction at sliding area, all invalid order all must filtering.
This step S60 (variation according to this momentum zone produces corresponding control signal) below will be described in detail in detail:
1. the location gesture is regardless of menu place pattern, all finds out the momentum zone with original resolution, produces real work corresponding window (as shown in Figure 5) again.After finish the location this master menu opened and be shown in (this master menu picture comprises most options) on the screen.Workflow as shown in Figure 9.
2. to look present place menu be master menu or submenu to the cancellation gesture, and decision is will return the last layer menu or close menu.Workflow as shown in figure 10.
3. increment gesture: if at present at master menu, then functional areas, top menu is to right rotation.If when submenu, if function choosing-item is not selected, then function choosing-item is to right rotation; If when choosing function choosing-item,, carry out incremental function according to present function choosing-item definition.Workflow as shown in figure 11.
4. the then similar increment gesture of decrement gesture, just functional areas, top menu is to anticlockwise, or carries out reduction functions.Workflow as shown in figure 12.
5. click gesture: if at present at master menu, except that the center job was clicked effectively, all the other were invalid.After clicking job, promptly enter the submenu of this project.As when the submenu, when clicking function choosing-item, function choosing-item can start (On), then can close (Off) when again by one time.When clicking another function choosing-item, former function choosing-item is closed automatically, guarantees to have only simultaneously a function choosing-item to be activated, as radio button.Workflow as shown in figure 13.
