Embodiment
The schematic flow sheet of the method embodiment of elimination combination piece of the present invention has been shown among Fig. 1, and as shown in Figure 1, it comprises step:
Step S101: discern the background combination in the captured image;
Step S102: captured image is handled, eliminated the piece of background combination in the captured image.
Wherein, When in above-mentioned steps S101, discerning the background combination in the captured image, various implementation can be arranged, for example; Can be through respectively increase the sign of a special color or nailing material at four edges of combination; Perhaps set 1 to 2 special pixel value in four corners of screen, perhaps the screen edge at spliced display wall adds at least three outstanding marks, thereby can be through discerning the demonstration edge that these special markings automatically identify the background combination when video camera is taken; And then identifying the background combination in the captured image, concrete implementation does not repeat them here.
When in above-mentioned steps S102, the background combination in the captured image being handled, eliminating the piece of background combination in the captured image; According to actual needs; Multiple different processing mode can be arranged; In a kind of therein mode; Can be to utilize original combination input signal, the picture signal of original combination input is carried out convergent-divergent after, to the background combination in the captured image partly replace or with the output that superposes of isolated clear foreground picture; In other a kind of mode, can be through carrying out the laggard line output of piece part of convergent-divergent covering background combination behind the piece of discerning background combination in the captured image, to each display unit in the captured image.Below just describe respectively to the concrete example of these implementations.
Concrete example 1
The schematic flow sheet of method of the piece of the elimination combination in this concrete example has been shown among Fig. 2, in this example, has been after the picture signal of original combination input is carried out convergent-divergent, describes with the output that superposes of isolated clear foreground picture.
As shown in Figure 2, in this concrete example, method of the present invention comprises step:
Step S201: discern the background combination in the captured image, get into step S202;
Step S202: confirm that background combination and the total painting reduction of area of captured image in the captured image put scale-up factor, get into step S203;
Step S203: when the details in a play not acted out on stage, but told through dialogues of synchronizing signal, take; Obtain comprising the realtime graphic of details in a play not acted out on stage, but told through dialogues background combination and clear foreground picture; And isolate the clear foreground picture in this realtime graphic; This foreground picture be in the captured image except the picture of background combination part, get into step S204;
Step S204: the picture signal of original combination input is put scale-up factor according to above-mentioned total painting reduction of area carries out convergent-divergent, with the image that obtains behind the convergent-divergent corresponding to the clear foreground picture of the details in a play not acted out on stage, but told through dialogues background combination position in the realtime graphic as bottom layer image, after separating as the top layer images laggard line output that superposes.
When confirming among the above-mentioned steps S202 that the total painting reduction of area is put scale-up factor, being that the image that rectangle and video camera shooting are exported also is the characteristic of rectangular image usually based on combination, can be the scaling that calculates transverse and longitudinal respectively.Definite mode synoptic diagram of scaling coefficient has been shown among Fig. 3.
Suppose that the coordinate of the captured image of one of them video camera observation point in coordinate system is as shown in Figure 3, four edge angle coordinate points of shot by camera image be (x0, y0), (x3; Y0), (x0, y3), (x3, y3); Four edge coordinate points of the background combination in the shot by camera image for (x1, y1), (x2, y1), (x2; Y2) and (x1, y2); Thereby can calculate the scaling coefficient of the whole picture of background combination and shot by camera in this shot by camera picture in view of the above, this scaling coefficient comprises horizontal direction scaling coefficient and vertical direction scaling coefficient, is respectively:
Horizontal direction scaling coefficient=(x2-x1)/(x3-x0);
Vertical direction scaling coefficient=(y2-y1)/(y3-y0).
After obtaining this scaling coefficient, can the position coordinates scope and the scaling coefficient of the background combination in each shot by camera image be stored, use to make things convenient in the follow-up work process.
In existing style of shooting, in order to guarantee the shooting effect of video camera, all be the shooting of carrying out picture at the light field of synchronous signal line in the time usually, the wall picture supplies the user to watch to obtain clearly.Yet; In the present invention program,, take when then being selected at the details in a play not acted out on stage, but told through dialogues of synchronizing signal in order to distinguish the background combination effectively and foreground picture is handled; Utilize the light field of synchronizing signal and the difference of details in a play not acted out on stage, but told through dialogues; Cog region is told foreground image and details in a play not acted out on stage, but told through dialogues background combination clearly, obtains comprising the realtime graphic of details in a play not acted out on stage, but told through dialogues background combination and clear foreground picture, in order to implement to take in the details in a play not acted out on stage, but told through dialogues of synchronizing signal more accurately; With respect to existing synchronizing signal, the details in a play not acted out on stage, but told through dialogues time that can the proper extension synchronizing signal.
Because the visual effect of human eye; In a live telecast, human eye can't be felt has the existence of details in a play not acted out on stage, but told through dialogues, video camera has been shown among Fig. 4 has taken the synoptic diagram of human eye observation site picture constantly in the details in a play not acted out on stage, but told through dialogues of synchronizing signal; It is thus clear that human eye observes remains display frame clearly.But in fact; Video camera taken picture and human eye observation site picture when the details in a play not acted out on stage, but told through dialogues of synchronizing signal is taken is different; The synoptic diagram of the picture that video camera photographed when the details in a play not acted out on stage, but told through dialogues of synchronizing signal had been shown among Fig. 5, visible by figure, take through details in a play not acted out on stage, but told through dialogues in synchronizing signal; In the realtime graphic that obtains, details in a play not acted out on stage, but told through dialogues background combination can clearly be distinguished mutually with the foreground picture of combination and come.When reality was implemented, the tone in the time of can requiring foreground content (for example host's clothes, hair color etc.) with the display screen details in a play not acted out on stage, but told through dialogues was inequality, to avoid that follow-up processing procedure is caused interference.
The background combination part of video camera in the captured realtime graphic that obtains of the details in a play not acted out on stage, but told through dialogues moment of synchronizing signal; It will be the color background background color of dark saturation degree; Take the back in order to ensure details in a play not acted out on stage, but told through dialogues and form the color background background color, the screen of combination and piece can use same material.
Subsequently, video camera is carried out separation of images at the captured realtime graphic that obtains of the details in a play not acted out on stage, but told through dialogues moment of synchronizing signal handle, isolate the clear foreground picture in the realtime graphic.When specifically carrying out separating treatment, can be that the color settings with the details in a play not acted out on stage, but told through dialogues background combination in the realtime graphic is transparent or the color background background color, so that the stack in the subsequent process is synthetic.During enforcement; Chroma key function capable of using realizes, the background color through chroma key function details in a play not acted out on stage, but told through dialogues background combination is set to transparent, and existing linear editing device capable of using is realized; Existing linear editing utensil has the chroma key function, thereby also can not increase too much equipment cost.Then; According to above-mentioned definite scaling coefficient the picture signal of original combination input is carried out convergent-divergent; During convergent-divergent; The picture signal of original combination input multiply by the scaling coefficient; Thereby obtain the image of the equal size of indication range of the background combination in the realtime graphic with shot by camera, and, confirm the picture position of background combination when image is play output according to the position coordinates scope of the background combination in the captured image of being stored; The position of the image that will soon obtain behind the convergent-divergent is set to identical with the position of background combination in realtime graphic; Clear foreground picture after the image that obtains behind the convergent-divergent handled as bottom, through separation of images is as the top layer synthetic laggard line output that superposes and since in the top layer images except the background color of the details in a play not acted out on stage, but told through dialogues background combination of foreground image (for example host) clearly become transparent, thereby can obtain output image according to the mode that pixel superposes; And the wall display frame that can guarantee different camera observation point all is positive in the face of the televisor spectators, also can guarantee the consistance of each display unit picture.
In a concrete actual use, concrete use can be:
In the debug phase in early stage; Special processing is carried out in four corners to the screen edge of spliced display wall; The spliced display wall here can be the spliced display wall of any types such as DLP, LCD, LED; Be convenient to the screen edge of video camera identification spliced display wall, when having set and having begun to debug in the position of each video camera, each video camera is taken respectively; According to each shot by camera to image can be observed four edge coordinate points of background display wall; And and then confirm to the background combination of each video camera with respect to the scaling coefficient of the whole picture of shooting of this video camera and background combination to obtain can storing after this scaling coefficient, the position coordinates scope with respect to the position coordinates scope of the whole picture of shooting of this video camera, make things convenient in the subsequent process and use;
Get into operate as normal record broadcast state after; The host can get into and carry out hosting work in the picture; Utilize light field and the details in a play not acted out on stage, but told through dialogues identification prospect and the background image of synchronizing signal; The proper extension details in a play not acted out on stage, but told through dialogues time, take when being chosen in the details in a play not acted out on stage, but told through dialogues of synchronizing signal, thereby can obtain comprising the details in a play not acted out on stage, but told through dialogues background display wall and the realtime graphic of foreground picture clearly; Separation for fear of to the background display wall causes interference, can require the tone of foreground content (for example host's clothes etc.) when avoiding with the mosaic display screen details in a play not acted out on stage, but told through dialogues identical;
Color settings with each pixel of the details in a play not acted out on stage, but told through dialogues background display wall in the captured image is transparent then; Owing to be the shooting of when the details in a play not acted out on stage, but told through dialogues of synchronizing signal, carrying out; The color of background display wall picture is all darker, and the host may shelter from a part of combination in concrete hosting work, therefore; Be provided with when transparent; Can be with in the background combination scope in the captured realtime graphic, the pixel value color settings that reaches each pixel of certain specific threshold is transparent, this specific threshold is set according to actual needs, thereby can avoid the pixel that the host of prospect is corresponding also to be set to transparent;
Subsequently; According to above-mentioned definite scaling coefficient the picture signal of original combination input is carried out convergent-divergent; The indication range that makes background combination in the image that obtains behind the convergent-divergent and the captured realtime graphic is size on an equal basis; Then the image that obtains behind the convergent-divergent is placed the picture position of background combination at captured realtime graphic, the foreground image after the image that obtains behind the convergent-divergent is handled as bottom, through separation of images superposes as top layer and synthesizes laggard line output.
Concrete example 2
The schematic flow sheet of method of the piece of the elimination combination in this concrete example has been shown among Fig. 6; In this example, be the picture signal of original combination input to be carried out the laggard line output of background combination that the signal behind the convergent-divergent directly replaces in the photographic images describe.
As shown in Figure 6, in this concrete example, method of the present invention comprises step:
Step S601: discern the background combination in the captured image, get into step S602;
Step S602: confirm that background combination and the total painting reduction of area of captured image in the captured image put scale-up factor, get into step S603;
Step S603: when the details in a play not acted out on stage, but told through dialogues of synchronizing signal, take, obtain comprising the realtime graphic of details in a play not acted out on stage, but told through dialogues background combination and clear foreground picture, get into step S604;
Step S604: according to above-mentioned scaling coefficient the picture signal of original combination input is carried out convergent-divergent, with the laggard line output of details in a play not acted out on stage, but told through dialogues background combination in the captured realtime graphic that obtains of image replacement that obtains behind the convergent-divergent.
As implied above; In this concrete example 2; Be the picture signal of original combination input to be carried out convergent-divergent according to the scaling coefficient; After obtaining the image of the equal size of indication range of background combination in the realtime graphic with shot by camera, according to the position coordinates scope of the background combination in the captured image of being stored, with the image that obtains behind the convergent-divergent as the direct laggard line output of details in a play not acted out on stage, but told through dialogues background combination in the taken realtime graphic of replacement of bottom.
And in the use of reality; Because the difference of the angle that video camera is set; In concrete hosting work, the host may shelter from the combination of a part, therefore; When the image that after with convergent-divergent, obtains replaces details in a play not acted out on stage, but told through dialogues background combination; Can be according to image that obtains behind the convergent-divergent and background display wall corresponding relation, with in the background combination scope in the taken realtime graphic, pixel value each pixel of reaching certain specific threshold replaces, this specific threshold is set according to actual needs, thereby can avoid the pixel that the host of prospect is corresponding also to replace.
Identical in other technologies characteristic in the concrete example 2 and the above-mentioned concrete example 1 do not repeat them here.
Wherein, In the explanation of above-mentioned two concrete examples; Only describe with two kinds of modes of utilizing the image that obtains behind the convergent-divergent that the background combination in the captured image is replaced wherein; Based on the purpose of replacement, those skilled in the art's multiple other mode of can also deriving is replaced, and these deriving modes should all be included within the present invention program's scope.
In addition; In above-mentioned explanation, be to be that example describes, promptly after debugging the time to confirm the position coordinates scope of scaling coefficient and background combination in debugging, to be applied in the processing procedure of follow-up captured realtime graphic then to the concrete course of work; The position of each video camera is changeless; And the variation that the camera lens of not considering video camera furthers and zooms out, this is because in a lot of conventional TV programme, only need be applied to the switching between the captured image of each camera; Do not relate to that furthering of single camera zoomed out and the variation of angular transition, for example news category program.And in the radio, TV and film industries of reality; From the concrete needs of using, the application that some program still possibly further and zoom out, for example programme televised live; In this case; Can be for system increase the intelligent self-learning pattern, after the each focusing of camera lens, and detect the video camera shooting angle at every turn and change; System is all with automatic Start-up and Adjustment pattern, and the background combination that recomputates the shot by camera picture is with respect to the scaling coefficient of the whole picture of shooting of this shot by camera picture and the position coordinates scope of background combination.Get into operate as normal record broadcast state after, realtime graphic is separated, merges stack output image afterwards.When definite scaling coefficient, consider the combination that may be blocked a part by the host, can be that the characteristic of rectangle is taken all factors into consideration according to determined combination border, combination, concrete processing procedure does not repeat them here.
In addition; In the explanation of above-mentioned two concrete examples of the present invention; All be to take during with the details in a play not acted out on stage, but told through dialogues of video camera when the concrete work to describe in synchronizing signal; This is that the color of considering the background combination in resultant image when details in a play not acted out on stage, but told through dialogues is taken can obviously be different from the color of foreground image, thereby is convenient to the identification to the background combination, conveniently extraction and foreground picture clearly; And be convenient to replacement to background combination part; As long as can realize the replacement of background combination part in the photographic images and be unlikely to cause mistake replacement, also can be to take constantly, as long as the image that can realize obtaining behind the convergent-divergent is to the replacement output of background combination at the light field of synchronizing signal to foreground picture.
Concrete example 3
The schematic flow sheet of method of the piece of the elimination combination in this concrete example has been shown among Fig. 7; In this example, be with behind the piece of discerning background combination in the captured image, each display unit in the captured image is carried out the laggard line output of piece part that convergent-divergent covers the background combination is that example is explained.
As shown in Figure 7, in this concrete example, method of the present invention comprises step:
Step S701: discern the background combination in the captured image, get into step S702;
Step S702: calculate the position coordinates of each piece of background combination in the captured image, get into step S703;
Step S703: according to the position coordinates of each piece, calculate and to determine the zoom factor that each display unit of background combination in the captured image zooms to the setting position of adjacent piece, get into step S704;
Step S704: the zoom factor according to each display unit carries out convergent-divergent to the corresponding image of each display unit of background combination in the realtime graphic of shot by camera.
After the corresponding image of each display unit of background combination carries out convergent-divergent in to realtime graphic in step S704, scaled images is exported, can be realized the seamless output of the image of background combination part.
When in above-mentioned steps S702, calculating the position coordinates of each piece of background combination in the captured image; Consider that each display unit in same combination all is same size; And the distance between each display unit (being piece) is also identical usually; Therefore; Can calculate the position coordinates of each piece automatically according to edge coordinate point and the type of combination system and the size of display unit of background combination, illustrate among Fig. 8 and used the synoptic diagram that this mode is confirmed the position coordinates of piece in the background combination.
In shown in Figure 8; Be the identification of hypothesis through background combination in three outstanding marks of display unit frame interpolation of combination are realized photographic images automatically; In the example shown in Figure 8, be that the size of each display unit of hypothesis is all identical and each piece size is also identical.As shown in Figure 8, the coordinate that can in captured image, identify three outstanding marks for (x1, y1), (x2; Y1) and (x5 y3), is set in the video camera output picture; Px is a display unit length, and horizontal longitudinal joint gap length degree is L, and Py is the display unit height; Thereby, can have: 4Px+3L=x5-x1 according to wall system type and display unit size; 3Px+3L=x5-x2; 2Py+1L=y3-y1.Thereby can calculate: Px=x2-x1; L=(x5-x2-3Px)/3; Py=(y3-y1-(x5-x2-3Px)/3)/2.
And can calculate the position coordinates of each display unit in view of the above:
With the 0-0 display unit is example: the coordinate points in its upper left corner for (x1, y1), the coordinate points in its upper right corner be (x2, y1), the coordinate points in its lower right corner be (x2, y2), promptly (x2, y1+Py), the coordinate points in its lower left corner be (x1, y2), promptly (x1, y1+Py);
With the 0-1 display unit is example: the coordinate points in its upper left corner for (x2 ', y1), promptly (x2+L, y1); The coordinate points in its upper right corner be (x3, y1), promptly (x2+Px+L, y1); The coordinate points in its lower right corner be (x3, y2), promptly (x2+Px+L, y1+Py); The coordinate points in its lower left corner be (x2 ', y2), promptly (x2+L, y1+Py).
Employing algorithm in like manner can obtain the coordinate points of other display units.
Subsequently, according to the coordinate points of each display unit, can confirm zoom factor to each display unit.When carrying out convergent-divergent to each display unit; As long as each display unit carries out can covering respectively behind the convergent-divergent part and the piece that the part behind each display unit convergent-divergent can cover the background combination fully of the piece of background combination; Computation purpose for convenience; Can make the border of each display unit behind the convergent-divergent arrive the middle boundary of adjacent piece respectively, in following explanation, be that example describes so that the border of each display unit behind the convergent-divergent arrives the middle boundary of adjacent piece respectively.
With the 0-0 display unit shown in Fig. 8 is example:
When the border with this 0-0 display unit zooms to the middle boundary of adjacent piece, promptly need will by (x1, y1), (x2; Y1), (x2, y2), (x1, the picture of y2) forming is amplified to by (x1; Y1), ((x2+x2 ')/2, y1), ((x2+x2 ')/2, (y2+y2 ')/2), (x1; (y2+y2 ')/2) picture of forming, wherein, (x2 '+x2)/the 2nd, the intermediate value of horizontal direction piece; (y2 '+y2)/the 2nd, the intermediate value of vertical direction piece;
Thereby can obtain the zoom factor of 0-0 display unit; Wherein the amplification coefficient on the horizontal direction is: ((x2+x2 ')/2-x1)/(x2-x1); Amplification coefficient on the vertical direction is: ((y2+y2 ')/2-y1)/(y2-y1), image can adopt high order interpolation scheduling algorithm to realize the compensation of pixel when amplifying.
With the 0-1 display unit shown in Fig. 8 is example:
When the border with this 0-1 display unit zooms to the middle boundary of adjacent piece, promptly need will by (x2 ', y1), (x3; Y1), (x3, y2), (x2 ', the picture of y2) forming is amplified to by ((x2+x2 ')/2; Y1), ((x3+x3 ')/2; Y1), ((x3+x3 ')/2, (y2+y2 ')/2), ((x2+x2 ')/2, (y2+y2 ')/2) picture formed;
Thereby can obtain the zoom factor of 0-1 display unit; Wherein the amplification coefficient on the horizontal direction is: ((x3+x3 ')/2-(x2+x2 ')/2)/(x3-x2 '); Amplification coefficient on the vertical direction is: ((y2+y2 ')/2-y1)/(y2-y1), image can adopt high order interpolation scheduling algorithm to realize the compensation of pixel when amplifying.
Employing algorithm in like manner can obtain the zoom factor and the piece offset of other display units.
After calculating the zoom factor of each display unit, can be kept in the storage medium, handle with the seam convergent-divergent that disappears that is applied in the follow-up real-time shooting process.Wherein, when video camera is started shooting or the position is moved, the background combination be need discern again at every turn, zoom ranges and zoom factor that piece is located, confirmed to calculate each display unit carried out.
Carrying out convergent-divergent according to zoom factor when handling, can be to handle according to relative coordinate, at this moment, need convert absolute coordinates to relative coordinate earlier, deduct that (x1 y1) can obtain relative coordinate with each coordinate figure is corresponding.For ease of understanding, in following explanation, remain with absolute coordinates and describe.
In above-mentioned example shown in Figure 8, be that the equal size of size of each display unit of hypothesis, the situation that each piece size is also identical get off to realize the identification of piece and the calculating of zoom factor.In the actual installation process, because the problem of error, the size of each piece maybe be also inequality, therefore, and can be through the displaying contents of physics piece and display unit being distinguished the identification that realizes piece.The synoptic diagram of piece being discerned according to this mode has been shown among Fig. 9, shown in Figure 9 in, be that the combination with 3 row, 3 row is example describes.
In order better the physics piece of combination to be distinguished; Can be to coat a kind of special color material at the splicing seams of display unit; This color can adopt a kind of color of RGB three primary colours outside synthetic; To distinguish mutually, conveniently distinguish physics piece and background image content with the color that the background display wall can show.
In wherein a kind of application mode,, after taking through video camera, the image that photographs is confirmed piece, obtain the piece template, and, obtain the template position coordinate of shooting picture through the image binaryzation processing through export complete white picture at spliced display wall.
When carrying out the image binaryzation processing, if the brightness value of pixel then is output as 1, otherwise is output as 0 greater than setting threshold Y.Can confirm the piece boundary position of the image shown in Fig. 9 in view of the above; Wherein, The piece boundary position of horizontal direction is respectively: x0, x1, x2, x3, x4, x5......, the piece boundary position of vertical direction is respectively: y0, y1, y2, y3, y4, y5.......
Thereby can confirm the zoom ranges and the zoom factor of each display unit in view of the above, in view of the above each display unit carried out convergent-divergent, be example with the middle boundary that each display unit is zoomed to adjacent piece, in the example depicted in fig. 9:
For the 0-0 display unit:
