Principle of the present invention is described below.At first, utilize on the remote control function key to send control signal to television set, make television set enter TV interactive operation state, TV also shows a special mark automatically except that showing the interactive menu picture on picture on screen.Secondly, take this menu screen detecting mark by being installed in image collecting device on the remote control, and draw remote control position pointed by the position of calculating this mark, that is the specific part in the picture that should choose.At last, the instructs cursor that demonstrates a correspondence at the picture position that calculates feeds back to the operator.The operator can change the position of choosing or carry out selection operation with reference to this instructs cursor.
Below with reference to accompanying drawing embodiments of the invention are described.
At first with reference to the schematic diagram of figure 1 description according to the remote control system of the embodiment of the invention.Remote control system according to the present invention is by comprising remote controller and television set.According to principle of the present invention, determine the position that remote controller is pointed by the picture that detects screen display, and select the menu option that to select by the sensing of change remote controller.The screen detection itself is a relatively problem of difficulty, because the pattern on the screen constantly changes, extraneous background light also may change at any time, and native system to require detection speed be real-time, therefore detect and cause a lot of interference to picture.In order to address these problems, the present invention adopts the method for show label thing on video screen that enters behind the detected state, realizes that rapid and precise screen detects.
Specifically, image collecting device is installed on TV remote controller.When the function key on pressing remote controller switches to menu screen with picture, the position of the mark in the image that photographs by the image collecting device in the remote controller is detected the position of video screen in real time, determine the position and the sensing of remote controller indication, reach the purpose of choosing the ad-hoc location in the picture.
Comprise television set 1 among Fig. 1, the picture 3 that the image collecting device of remote controller 2 and remote controller is captured.The position at mark place and the position that remote controller points in screen of TV set, have been marked.What the oval part in the upper right corner showed in the screen of television set 1 among the figure is mark, the point that the remote controller that the round dot in the screen shows points to, the captured picture of image collecting device of reference number 3 expression remote controllers 2.
An embodiment of remote control system of the present invention is described below with reference to Fig. 2.As shown in Figure 2, this remote control system comprises remote controller part 21 and the television set part 22 of sending control signal.Wherein remote controller part 21 comprises the image collecting device 23 of gathering image, calculate and detect mark and calculate the chosen position calculation element 24 of instructs cursor position, partly launch the remote control signal transmission device 25 of remote signal to television set, be used for control system and enter or withdraw from the instruction enter key 26 that menu option is chosen state.Instruction enter key 26 comprises that menu chooses start key and choose cancel key.Television set part 22 comprises video display devices 27 and remote signal receiver 28, and other device (not shown) that comprises in the television set.
The operation of remote control system of the present invention is described below.Remote controller detects and whether to enter screen and chooses state, if the start key of choosing of remote controller is pressed, to image scanner 23, is camera in the present embodiment, and chosen position calculation element 24 sends and enters the instruction that on-screen menu is chosen state.Enter the signal that menu is chosen state by signal receiver 28 emissions of the signal projector in the remote controller 25 in being arranged on television set.Remote control system then enters menu and chooses state.At this moment, show alternative menu option on the video screen.As a kind of substitute mode, at present operated by rotary motion has a data key on the digital television remote controller, is used to receive the data broadcasting service of general video outside viewing and admiring.Thereby, also can be set in and make remote control system enter menu when data key is pressed to choose state.After entering menu and choosing state, the inner vision signal that produces mark to be detected of TV also shows this mark on screen.
Next, remote controller is pointed to display screen, image collecting device 23 on the remote controller, be camera in the present embodiment, begin to take the image of direction, and become vision signal to offer chosen position calculation element 24 captured image transitions to handle (its processing procedure will be described below), obtain remote controller position pointed thus, and the sensing position of definite remote controller is in the scope of which menu option, and make corresponding menu option be in highlighted state, that is, make this menu option of cursor pointing.After this, the user can point to by changing remote controller simply, and option and utilization instruction enter key 26 that the remote controller sensing will be selected are selected.
The screen position selecting device of prior art, for example common menu is chosen remote controller, enter behind the state of choosing general cursor or focus and fall within on certain menu bar, choose corresponding menu bar by key all around or the numerical key pressed on the remote controller, the inconvenience that operates is nature also.
Different with the position selecting device of prior art, the present invention need determine the position relation of remote controller and screen.This is to reach by the mark that detects on the screen.After having determined relative position relation, we just can determine the position that instructs cursor should be pointed to, and as remote controller is referred to left, cursor also can relative moving to left on screen, and giving people's sensation is the luminous point that is sent by remote controller as cursor.It is convenient and natural to operate.
In a preferred embodiment of the invention, at first be to detect mark, be the sign object point that we need with which point on the image of determining camera 23 shootings on the remote controller.Next is the position of determining mark, so that determine the central point of mark by these detected sign object points.Because the relative position of mark and screen determines, the relative position relation of having known mark and remote controller has also just been known the relative position relation of screen and remote controller.After having determined the position of mark, just can determine the position of the instructs cursor that on screen, will show by geometrical relationship.
Below the preferred embodiment that detects mark and calculating remote controller sensing position among the present invention is described in detail.The at first detection of description flags thing.At the upper right corner of screen show label thing, but the invention is not restricted to this, mark can be presented at any position on the screen, as the bottom right or the lower left corner etc.At this moment remote controller pointed at television screen, image collecting device 23, promptly camera is filmed mark.
In the present embodiment, determine mark by the color that detects mark.In the image of taking, adopt the some detection and the median filter method of HSI color model to detect mark in real time.Wherein H represents colourity (Hue), and S represents saturation (Saturation), and I represents brightness (Intensity).Usually, the RGB color model is the most commonly used, and it thinks that color is by red (Red), and green (Green), blue (Blue) three kinds of basic colors mix.The combination of the varying strength of each basic color has just constituted different colors.For example, if the maximum intensity of every kind of basic color represents that with 8 bits so the maximum intensity of every kind of basic color is exactly 255, then redness is R=255, G=B=0; And yellow is R=G=255, B=0.But along with the light and shade of light changes, three components of RGB change simultaneously, do not have to embody the independent description to color.
The HSI color space is the vision system from the people, can show the variation situation of tone, brightness and color saturation very clearly.Usually the color harmony saturation is commonly referred to as colourity, is used for representing the classification and the depth degree of color.Because people's vision far is better than sensitivity to color to the sensitivity of brightness, handles and identification for the ease of color, people's vision system often adopts the HSI color space, and it more meets human vision property than rgb color space.Big quantity algorithm all can use in the HSI color space easily in image processing and computer vision, and they can separate processes and are separate.Therefore, in the HSI color space workload of simplified image analysis and processing greatly.
The HSI color space is the different representations of same physical quantity with rgb color space, thereby exists transformational relation between them.
Marker detection among the present invention be color showing with object from the RGB color notation conversion space to the HSI color space.After image collecting device 23 photographs mark, its color is handled the color binary map of the RGB that obtains this mark.Then, chosen position calculation element 24 is by calculating the HIS value that following conversion formula can obtain mark.Wherein obtain the gray value of mark by following formula (1)
I=(R+G+B)/3 (1)
Wherein R, G, B represent trichromatic numerical value.
The saturation of formula (2) the calculation flag thing below utilizing:
S=1-min(R,G,B)/I (2)
Wherein (B) expression is got R, G, the minimum value among the B to min for R, G.
Formula (3) below utilizing calculates colourity:
Wherein F is a variable, utilizes empirical equation to obtain F=(2*R-G-B)/(G-B);
It is constant substantially that H, S component can keep when bright and dark light changes, so when illumination variation, can detect mark by detection H, S component, eliminates the interference of extraneous light, reached the purpose that detects mark.As an example, chosen position calculation element 24 can be implemented by microprocessor.Fig. 4 illustrates an embodiment of the mark of selection, this mark adopts single color characteristic (blue look), after being mapped to colourity H and saturation S component, threshold ratio by colourity and saturation are set in the H that will calculate and S component value and the chosen position calculation element 24, point more than or equal to predetermined threshold is set to 1, point less than this threshold value is set to 0, satisfies the predetermined condition image section and is mark.Obtain the binary map B of mark thus, thereby obtain the candidate point of mark.Wherein be made as 1 point among the B and be the sign object point.Inevitably, some isolated noise spots are arranged in binary map B, can adopt median filter method to remove these isolated noise spots.By above-mentioned processing, can determine the mark that shows on the screen.
Adopt possible that the object of same color in the image of color that the mark of solid color exists mark and screen display obscures mutually in the foregoing description.As an alternative, detect mark other execution mode also can be arranged.As mark can be arranged on outside the screen after entering detected state, has increased production cost outward though mark is arranged on screen, and the effect of handling can be better, because the interference of its suffered screen picture is smaller.
The detection method computational speed of above-described some color detection and simple filtering is than very fast, but also can adopt other image processing techniques, as pattern recognition and filtering techniques that some are comparatively complicated etc.For example the design of mark can be adopted the shape of rule, as circle, rhombus etc. can also be assisted method with template matches in the pattern recognition for the detection of mark like this, after promptly having known the shape of mark, just can be not removing with the noise spot of this form fit.
The method that can also judge with multiple color combination of the detection of mark in addition, promptly mark adopts multicolour and suitable distribution of color shaped design to improve the antijamming capability of detection.Fig. 6 shows another embodiment of mark.Comprise three kinds of colors of regular distribution on the space in this mark, the rule in this example is: the left side of blue dot is that redness and the right are green.After detecting three kinds of colors, have only the point of the spatial distribution rule that satisfies three kinds of colors just to think to indicate object point.This method can improve the stability of system, overcome the interference that may be subjected in the testing process effectively, as having occurred colourity situation all identical with mark fully with saturation or the like on the screen.
More than illustrated the captured mark image of camera is converted into binary map B, be made as 1 point among the B and be the sign object point.Can determine the position of central point in the captured image of camera of mark thus.
