In the embodiment of the present invention, the interaction platform of a Table top type is created, in the implementation, body-sensing camera 5 is using deep
Spend camera, the acquisition visual angle of body-sensing camera 5 covers entire 4 region of wall image and is not blocked by human body, body-sensing camera 5 with
Minimum range between wall image 4 is limited in 0.75m, and the maximum distance between body-sensing camera 5 and wall image 4 determines mutually
The accuracy that dynamic point calculates, recommendation maximum distance are 1m.Simultaneously, therefore, to assure that body-sensing camera 5 install after will not by mobile and
Interference.Even if small vibration can all interfere depth value, the accuracy of interaction is reduced.In addition, it is necessary to carefully confirm body
Feel the installation site of camera 5, body-sensing camera 5 cannot be hidden by user on one's feet completely in face of the visual field of co-acting planar
Gear.As such, it is preferred that body-sensing camera 5 is mounted on upper position before wall image 4, the acquisition visual angle of body-sensing camera 5 is inclined
Entire 4 region of wall image is covered obliquely.
In this way, with reference to Fig. 7, above-mentioned corporate image methods of exhibiting disclosed by the embodiments of the present invention further include: taken the photograph by body-sensing
As operational motion image of the first 5 acquisition human body on wall image 4；It is acted according to the operational motion image recognition operations of acquisition；It holds
Row operational order corresponding with operational motion；And control the corporate image after several projection presentation devices 3 execute operational order
Display data is shown on wall image 4.
In above-mentioned corporate image methods of exhibiting, since filtering, when human body moves on the wall, the operational motion of acquisition is not used
Image cannot correctly feedback information, have certain error.Image inevitably mixes the dry of noise during interaction
It disturbs, noise may be that any one link of the input in picture signal, transmission, output generates.It could also be possible that in hardware
Do not generated for aspect.The interference for introducing the image appearance of noise pollution can be observed with the naked eye, produce breakpoint, image is trembled
Dynamic, situations such as contact is insensitive.In order to be effectively removed the interference of outside noise signal, Image denoising algorithm, people can be added
Body can feed back the motion images of continuously smooth out when doing sliding action on wall image.
Therefore, it is highly preferred that with reference to Fig. 4, above-mentioned projector controller 2 disclosed by the embodiments of the present invention further include: number letter
Number filter 26, removes dryness each pixel of the operational motion image of acquisition for removing dryness algorithm model using image, extensive
Original image is arrived again and is sent to picture recognition module 27；Wherein, described image removes dryness the estimated value that algorithm model passes through the k-1 moment
The estimated value at current time is obtained with current observation.
It is described according to acquisition in above-mentioned corporate image methods of exhibiting disclosed by the embodiments of the present invention in this way, with reference to Fig. 8
Before the movement of operational motion image recognition operations, algorithm model is removed dryness to acquisition using image by digital signal filter 26
Each pixel of operational motion image is removed dryness, and original image is restored to；Wherein, described image removes dryness algorithm model and passes through k-1
The estimated value at moment and current observation obtain the estimated value at current time.
Body-sensing camera 5 receives image, is then passed to projector controller 2.In the meantime, projector controller 2 obtains
Image information can inevitably mix the interference of noise, need to filter to eliminate or reduce noise.Digital signal filter 26 is
The digital signal filter of algorithm model is removed dryness using image, image removes dryness algorithm model and passes through the estimated value at k-1 moment and work as
Preceding observation obtains the estimated value at current time, is the relatively high recursive algorithm of a real-time.Input is observation, defeated
Out be current time estimated value, image is denoised, to restore the step of original image as follows:
(1) estimate any one pixel X (i, j) in all pixels point (0-255), it is assumed that
X1(i, j)=X (i, j) (1)
(2) estimate horizontal direction pixel X2(i, j), its value are the pixel that leftmost pixel point adds the first step:
X2(i, j)=aX (i, j)+brX (i, j-1) (2)
A, b are weight coefficient in formula, and a+b=1, r are the related coefficient of horizontal direction image.
(3) estimate X3(i, j), its value are the sum of the pixel of right pixels point and second step:
(4) estimate X4(i, j), its value are the sum that Kalman filtering and third step are estimated:
In formula, K is kalman gain.
(5) estimate X5(i, j), its value is the average value of the 4th step both vertically and horizontally:
In formula, X4x(i, j) is the 4th step horizontal direction estimated value, X4y(i, j) is the 4th step vertical direction estimated value.
From the above equation, we can see that:
X*=AX+K (Y-Y*) (6)
Y*=BX* (7)
In formula, X is state vector, and A is state matrix, and B is that output matrix , ﹡ indicates predicted value, in which:
X=[X (i, j-1) X (i, j) X (i, j+1)] (8)
C=[0 1 0] (10)
By the calculating of above-mentioned steps, each pixel can be restored to without pixel of making an uproar, realize the denoising to whole image
