In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.
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.
Fig. 1 is the process flow diagram of remote controller position acquisition methods in an embodiment of the invention.This method may further comprise the steps:
Step S10 is provided with image unit at telepilot, with the optics property distinguished according to the screen frame, obtains the frame of screen, and utilizes the diagonal line of frame that screen is carried out subregion; In one embodiment, an image unit can be set at the front end of telepilot, this image unit is specifically as follows a camera.In general, the screen frame of Web TV has significantly different with other position in color or brightness, therefore, can be by camera according to the difference in color or the brightness, obtain the quadrilateral frame of Web TV screen, and utilize diagonal line that this quadrilateral frame is divided into four delta-shaped regions, so that subsequent treatment.
Step S20 obtains the imaging center of image unit, and obtains the position of telepilot at screen according to the relative position relation of this imaging center and diagonal line intersection point.As everyone knows, camera has imaging region, and for example the rectangle of digital camera becomes frame, and this rectangle becomes frame to have an imaging center, the intersection of diagonal of frame.The diagonal line intersection point that can utilize above-mentioned screen draws the position of telepilot at screen as the reference point according to diagonal line intersection point and cornerwise ratio change calculations.
As shown in Figure 2, big rectangular box ABCD is the imaging region of camera, the quadrilateral A1B1C1D1 that distortion is arranged that the inside is little then is the imaging of screen rectangle being shot, as can be known from Figure, the diagonal line AC of large rectangle ABCD, BD intersection point O are imaging center, the sensing position of this telepilot just, the diagonal line A1C1 of little quadrilateral A1B1C1D1, B1D1 intersection point O1 then are the centers of screen rectangle being shot.The relative position of O point in little quadrilateral A1B1C1D1 is exactly the sensing position of telepilot on the Web TV screen.
As shown in Figure 3, among the above-mentioned steps S20, also can may further comprise the steps:
Step S21 according to the screen diagonal intersection point, obtains the proportionate relationship of each line segment in the diagonal line, and obtains the position of telepilot with respect to screen according to this proportionate relationship; If telepilot is subjected to displacement, the image model that camera absorbed with have before significantly different.For example, suppose that with the peripheral profile rectangle of screen picture be example, when camera faced rectangular centre, the image that obtains also was a rectangle, and the size of this rectangle has then reflected the distance of the two, and promptly the near more rectangular image of distance is big more, otherwise then more little.In like manner, when camera during from screen left side pickup image since camera from the screen left side distance less than distance from the right, the image that therefore obtains rectangle approaches little trapezoidal in big the right, a left side, camera situation on the right is just in time opposite.According to above-mentioned principle, can calculate the position of the relative screen of imaging center of telepilot according to cornerwise length ratio difference.For example, can be provided with one with reference to diagonal line, obtain this with reference to the intersection of diagonal coordinate, then according to this with reference to the proportion of deformation of line segment and the relation between the intersecting point coordinate, obtain the distortion correction parameter, during with convenient telepilot displacement, calculate, draw the position of telepilot at screen according to this distortion correction parameter
Step S22 exports telepilot to telepilot with respect to the positional information of screen, so that show on screen.After the relative position information of above-mentioned telepilot and screen obtains, can export it to telepilot, so that be presented on the screen.
In the foregoing description, also can comprise the step of obtaining the screen frame according to light source, in some particular environment, the optics of the screen property distinguished is not strong, the screen capture situation of difficult with reply.For example, in the environment, the border color of screen is obvious inadequately in the open, and can be provided with light source this moment at the frame of screen, so that catch.
Fig. 4 shows the structure of remote controller position deriving means in an embodiment of the invention.This remote controller position deriving means comprises:
With reference to shown in Figure 5, above-mentioned data processing unit 20 can comprise:
Diagonal line processing module 21 is used for obtaining the proportionate relationship of each line segment in the diagonal line according to the screen diagonal intersection point, and obtains the position of telepilot with respect to screen according to this proportionate relationship; When telepilot is subjected to displacement, the image model that camera absorbed with have before significantly different.For example, suppose that with the peripheral profile rectangle of screen picture be example, when camera faced rectangular centre, the image that obtains also was a rectangle, and the size of this rectangle has then reflected the distance of the two, and promptly the near more rectangular image of distance is big more, otherwise then more little.In like manner, when camera during from screen left side pickup image since camera from the screen left side distance less than distance from the right, the image that therefore obtains rectangle approaches little trapezoidal in big the right, a left side, camera situation on the right is just in time opposite.According to above-mentioned principle, can calculate the position of the relative screen of imaging center of telepilot by diagonal line processing module 21 according to cornerwise length ratio difference.For example, can be provided with one with reference to diagonal line by diagonal line processing module 21, obtain this with reference to the intersection of diagonal coordinate, then according to this with reference to the proportion of deformation of line segment and the relation between the intersecting point coordinate, obtain the distortion correction parameter, during with convenient telepilot displacement, calculate, draw the position of telepilot at screen according to this distortion correction parameter.
Positional information output unit 22 is used for exporting telepilot to telepilot with respect to the positional information of screen, so that show on screen.After the relative position information of above-mentioned telepilot and screen obtains, can export it signal transmitter unit of telepilot to by positional information output unit 22, be emitted to Web TV and be presented on the screen for it.
In one embodiment, above-mentioned image unit 10 comprises light source capture module 11, is used for obtaining the screen frame according to light source.For example, in some particular environment, it is not strong that the optics of screen is distinguished property, and as in the environment in the open, the border color of screen is obvious inadequately, and can be provided with light source this moment at the frame of screen, catches light sources to obtain the screen frame by light source capture module 11.
The present invention also provides a kind of telepilot, and this telepilot comprises signal transmitter unit and above-mentioned remote controller position deriving means.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
