Based on the system principle shown in Fig. 1, below to the method provided in an embodiment of the present invention that character is inputted to television set
It is described in detail：
Fig. 2 shows the implementation process of the method provided in an embodiment of the present invention that character is inputted to television set, and details are as follows：
In S201, acquisition is printed with the plane of keyboard pattern each picture of the key legend in camera shooting image
Plain position, the camera are arranged on the remote control of television set, and the remote control is with the plane in fixed angle and position
Put relation.
In the present embodiment, once remote control and be printed with keyboard pattern plane putting position it is fixed after, only
Want remote control and plane no longer to move, then the angles and positions relation of remote control and plane is decided, and is not rechanged, this
When, in the image captured by camera on remote control, each key legend in the keyboard pattern in plane is in the figure
Location of pixels as in is all changeless.
No matter whether as one embodiment of the present of invention, before character is inputted to television set every time remote control is put again
Device and plane, if the angles and positions relation between remote control and plane can keep fixed, such as institute in Fig. 1 embodiments
That states places the situation of remote control using the support being placed on fixed position, then each key legend is shot in camera
Location of pixels can in image is predicted and prestored by designer into system in advance, without passing through before every use
The means such as image procossing reacquire once location of pixels of each button image in camera shooting image.
As another embodiment of the present invention, before character is inputted to television set every time, remote control and plane are can be with
Again put, in this case, the angles and positions relation between remote control and plane may change, then need
After putting again every time, initialization operation is carried out, each key legend under new angles and positions relation is obtained and is imaging
Location of pixels in head shooting image.Specific initialization operation process will be described in detail in subsequent embodiment, herein
Repeat no more.
In S202, the first image for having object to block the keyboard pattern of the camera shooting is extracted.
In the present embodiment, user can simulate real physical keyboard scene, pass through finger or other objects（Such as
Pen, waddy）The key legend in plane is clicked on, to complete the character input to television set.In above process, positioned at remote control
On camera need carry out captured in real-time, and extract camera shooting the realtime graphic for thering is object to block keyboard pattern.
Specifically, camera can carry out captured in real-time to plane, by compare current frame image that camera photographs with
The difference of previous frame image, or the current frame image photographed by comparing camera photograph not with preset camera
There is the difference that object blocks the image of keyboard pattern, you can to judge currently in the image of camera shooting, if there is thing
Body blocks the keyboard pattern in plane.For example, when judging compared to not thering is object to block for the picture frame of keyboard pattern, certain
The color change of individual key legend position more than 80%, then it is considered that now thering is object to block keyboard pattern.Once judge
Go out to have object to block the keyboard pattern in plane, then extract the realtime graphic of the frame, for carrying out image procossing, further determine that
The position that object blocks.
Preferably, an adjustable key press time can be set, to adjust the susceptibility of whole character input system, avoided
In the case where user's hand is only to skim over plane, also to the realtime graphic situation about being extracted of camera shooting.Such as Fig. 3
Shown, S202 includes：
S301, judge the object blocked in same pixel position the keyboard pattern time whether exceeded it is default
Key press time.
S302, when the object block in same pixel position the keyboard pattern time exceeded it is described it is default by
The key time, extract described first image.
In S203, according to picture of the one end of the object at the top of the keyboard pattern in described first image
Plain position, character corresponding to the key legend positioned at the location of pixels is defined as to input character.
It is accustomed to according to the typewriting of human body, during normal typewriting, finger is that direction is directed towards at the top of keyboard, and is referred to
The location of sharp is the key position pressed, and therefore, in the present embodiment, will block the object of keyboard pattern near key
The location of one end at the top of disk pattern is defined as the key position pressed, and by image procossing, gets the position and is taking the photograph
Location of pixels in the first image shot as head, the information got according to S201, by positioned at the button figure of the location of pixels
Character corresponding to case is defined as being currently needed for the character inputted to television set.
In S204, the input character is sent to television set.
In the present embodiment, by the short haul connection mode such as infrared remote control, the input character that S202 is determined is sent
Into television set, the character input in the edit box that television screen is shown thus is completed.
By step described in Fig. 2 embodiments, can complete to sequentially input character into television set, after input,
By the respective keys on remote control come termination character input operation, now, the camera on remote control also no longer works, printing
The plane for having keyboard pattern also can correspondingly be folded or rolled up storing, very convenient.
Fig. 4 shows the specific implementation flow of the method S201 provided in an embodiment of the present invention that character is inputted to television set
Figure, in the present embodiment, if the angles and positions relation between remote control and plane changes, need to grasp by initializing
Make to obtain location of pixels of each key legend in camera shooting image, specifically, in the present embodiment, by flat
Set in face outside keyboard pattern several mutually possess preset area than color lump, calculate each key legend and these color lumps
The distance between determine character that each key legend represents.Specifically, the quantity of color lump is at least three, every to ensure
The distance between individual key legend and these color lumps value is unique for other key legends.
In S401, the second image for not having object to block the keyboard pattern of the camera shooting is obtained.
That is, all key legends that camera needs to shoot in a sheet of planar upper keyboard pattern in initialization are not hidden
Second image of gear.
In S402, each pixel in second image is traveled through, by primaries（RGB）Value is more than predetermined threshold value
Pixel is defined as Colored pixels, obtains M Colored pixels continuum, and the M is the integer more than 3.
As shown in figure 1, because for compared to background colour, the color of key legend and color lump is deeper than the back of the body in plane
Scenery, therefore, in the present embodiment, a default rgb value can be set, the process of each pixel in the second image is traveled through
In, respectively by the rgb value of the pixel currently traveled through compared with the default rgb value, if the rgb value of the pixel currently traveled through is big
Rgb value is preset in this, then it is assumed that the pixel is defined as Colored pixels by the pixel equivalent to being coloured for background colour, by
This can obtain M Colored pixels continuum.
Because in the present embodiment, for each color lump, it is made up of continuous Colored pixels, and for every
For individual key legend, the character that is indicated on its button and its button is with respect to for background and coloured, therefore, its be also by
Continuous Colored pixels composition, therefore, this M Colored pixels continuum corresponds to N number of color lump and each key legend respectively,
That is, multiple Colored pixels continuums as obtained from traveling through the second image are color lump or key legend region.
As a specific embodiment of the present invention, M Colored pixels can be obtained by the way of Run- Length Coding
Continuum.Specifically：After the second image is got, a matrix, a length of second figure of the matrix can be defined first
The pixel count of the length of picture, the wide pixel count of a width of second image；And then a regional structure body class is defined, including it is following
Variable：Validity flag, the starting pixels position of Colored pixels continuum, the end pixel point position of Colored pixels continuum
Put, the rgb value of Colored pixels continuum color, the coordinate value of Colored pixels continuum barycenter, Colored pixels continuum
Area, the pointer etc. that points to next Colored pixels continuum；Hereafter, every a line in the second image is traveled through, will be greater than pre-
If the pixel of threshold value then judges next pixel value, and will be greater than the continuous of predetermined threshold value as a regional structure body variable
Pixel is all placed in a region, finally judges whether the region area is more than color lump or the due area of key legend,
It is to be set to validity flag effectively, and using the region as a Colored pixels continuum.Meanwhile not with a upper region
Continuous but pixel RGB values are more than the region of predetermined threshold value as next Colored pixels continuum, by that analogy, until obtaining institute
Some Colored pixels continuums.
In S403, N number of color lump is determined in the M Colored pixels continuum.
After M Colored pixels continuum is obtained, according to the color lump being had predetermined that during graphic-print
With the position relationship or distinguishing characteristics of key legend, you can to determine N number of color in this M Colored pixels continuum
Block.
For example, as shown in figure 1, three preset area ratios are printed with plane as 3：2：1 color lump, and these three color lumps are equal
Positioned at the periphery of keyboard pattern, i.e. relative to all key legends, these three color lumps are closer to the side of the second image
Edge., can be by above-mentioned color lump and the position relationship of key legend, by three near as a kind of possible implementation
Two image edges, and area ratio is 3：2：The 1 continuous region of Colored pixels is identified as these three color lumps.
, can also be by one or more color during graphic-print as alternatively possible implementation
The area of block is printed to the area more than any key legend, thus, you can with continuous directly by the maximum Colored pixels of area
Region is defined as one of color lump, and determines other color lumps according to the preset area ratio between color lump.
Determine that the mode of N number of color lump includes but is not limited to above two in M Colored pixels continuum, herein not
Repeat one by one.
In S404, according to the pre-determined distance value of each key legend and N number of color lump, respectively at the M
Each key legend is determined in Colored pixels continuum.
After N number of color lump is determined in M Colored pixels continuum, remaining Colored pixels continuum is i.e. corresponding
Key legend, now, according to each key legend being had predetermined that during graphic-print and this N number of color lump away from
From value, i.e., it can determine each key legend again respectively in this M Colored pixels continuum.
Specifically, can be according to the location of pixels on the upper and lower, left and right border for each color lump determined in S403, to count
The location of pixels where the barycenter of each color lump is calculated, similarly, the pixel where the barycenter of each key legend can also be obtained
Position, location of pixels of the location of pixels where with the barycenter of each color lump where barycenter by calculating each key legend,
The distance value of each key legend and each color lump, and the distance value one of each key legend and N number of color lump can be determined
Surely it is mutually different, thus, it is possible to distinguish each key legend, is shot so that it is determined that going out each key legend in camera
Location of pixels in image.
In S405, location of pixels of each key legend in second image is defined as it and taken the photograph described
As the location of pixels in head shooting image.
Thus, that is, the initialization to character entering function is completed, as long as the angles and positions relation of remote control and plane
Do not change, then location of pixels of each key legend determined in S405 in camera shooting image will not also change.
The embodiment of the present invention by TV remote controller integrated camera be printed with the plane of keyboard pattern to shoot,
And increasing image processing module on a remote control, identification, the finger of analysis camera shooting or other objects click on the plane
