Fig. 3 is referred to, is the structure chart of the correction parameter acquisition device of Fig. 2 Stereo display equipment.This device includes Image acquisition unit 31, crosstalk fringe detection unit 32, Dip countion unit 33 and parameter acquiring unit 34.

Image acquisition unit 31 is used to obtain the stereo-picture that the stereoscopic display device 22 is shown.In correction course, It generally requires repeatedly to adjust the display parameters of stereoscopic display device 22, to find out optimal parameter.And filming apparatus 23 Track up, and the image frame that will be taken can be carried out to the image frame for including the display screen of stereoscopic display device 22 in real time Send image acquisition unit 31 to.

Image acquisition unit 31 obtains the stereo-picture of the display of stereoscopic display device 22 from the image frame received, with The variation of image when obtaining the adjustment of each subparameter, and the stereo-picture that will acquire sends crosstalk fringe detection unit 32 to.

Since the image frame that filming apparatus 23 obtains not only includes the stereo-picture that stereoscopic display device is shown, there are also wrap The external environment other than display area is included, for the accuracy for avoiding external environment influence correction parameter, needs image acquisition unit 31 before obtaining stereo-picture, need to determine the display area of image frame Stereo display equipment 22, first to determine viewing area The stereo-picture of display in domain.

Specifically, image acquisition unit 31 includes receiving subelement and determining subelement.Wherein, receiving subelement is for connecing Receive the image frame that screen is shown including the stereoscopic display device 22 that filming apparatus 23 takes；Determine that subelement is used for really Determine the screen area of the received image frame Stereo display equipment 22 of receiving subelement, and obtains what the screen area was shown Stereo-picture.It determines that subelement can use the image channel value in image analysis technology extraction display area, then uses side Edge detection, detects that the boundary point and boundary curve of display area detect display area in conjunction with image area.

Further, Figure 20 is referred to, determines that subelement includes: brightness of image analysis 204 binary conversion treatment of subelement Unit 201, range searching subelement 202 and merger divide subelement 203.

Brightness of image analysis subelement 204 is used to obtain the brightness value of pixel in image frame.

Binary conversion treatment subelement 201 is used to obtain brightness of image analysis subelement 204 according to preset luminance threshold Image frame in pixel brightness value carry out binary conversion treatment, to obtain corresponding quasi- screen area.The two of so-called image Value exactly sets 0 or 255 for the gray value of the pixel on image, that is, whole image is showed apparent There is black and white visual effect.So as to generally tell screen area.

Range searching subelement 202 on the quasi- screen area after binary conversion treatment for searching for the area of preset shape Domain.The region of the setting shape can be rectangular area, border circular areas.Delta-shaped region etc., according in stereoscopic display device Source stereotome subject to.

The region that merger divides the preset shape that subelement 203 is used to search carries out merger division, described in determination The screen area of stereoscopic display device described in image frame.The quantity for the setting regions that range searching subelement 202 searches out It might have very much, these setting regions may vary, and mutual position may be coincidence, staggered, separated. The process of merger, which can be, assigns weighted value, the i.e. number of some area coincidence according to the coincidence number in these regions searched out It is more more then to assign a higher weight.The process of division refers to that the weight distribution according to the region after merger, removal weight are small In the region of certain value, and the region of setting shape is marked off again, as screen area.

Crosstalk fringe detection unit 32 is used to detect the crosstalk striped in the stereo-picture.Crosstalk fringe detection unit 32 It can be by the color value of pixel in calculating stereo-picture, to obtain the crosstalk striped in stereo-picture.For example, can pass through By stereoscopic image conversion to HSV space, the value on color component is obtained, HSV space is to embody a kind of face of color intuitive nature The colour space, also referred to as hexagonal pyramid model (Hexcone Model), there are three color parameters respectively in this color space: tone (Hue), saturation degree (Saturation) and brightness (Value).For red green crosstalk striped, color value 0 to 20 it Between region be it is red, region of the color value between 40 to 60 is green, in this way it is known that color on stereo-picture Distribution, to detect on stereo-picture with the presence or absence of crosstalk striped.It is a perspective view to be corrected in conjunction with referring to fig. 4 Picture, wherein black region indicates red, and white space indicates green, and as can be seen from Figure 4 the stereo-picture has three red Three Greens Six crosstalk stripeds.

Dip countion unit 33 is used to calculate the inclination angle of the crosstalk striped detected.It can be seen from figure 4 that crosstalk Striped is often inclined, and entire correction course, if if embodying, exactly first making crosstalk striped with continuous image Center is overlapped with the center of display area, then becomes larger the width of crosstalk striped in image to reduce the number of crosstalk striped Amount, until single tone occupies display area.And the spectrophotometric result in order to reach, and prevent from occurring on stereo-picture Extension angle (it hangs angle and refers to that some region does not have display pattern, such as a pure red rectangle stereo-picture on stereo-picture, one Angle is not displayed in red pattern), the present embodiment, which is used, to be calculated in the case where crosstalk striped is vertical by parameter acquiring unit 34 Correction parameter, to reach preferable display effect and correction efficiency.It is of course also possible to use in the case where crosstalk jail-bar level Correction parameter is calculated, the application is not limited thereto.

Further, Dip countion unit 33 can be by obtaining the line of demarcation between crosstalk striped, and calculates described point The inclination angle in boundary line, using the inclination angle as the crosstalk striped.Fig. 5 is referred to, is a kind of Dip countion of the embodiment of the present invention The structure chart of unit.This Dip countion unit 33 further comprises that line of demarcation obtains subelement 51 and computation subunit 52.Boundary Line obtains subelement 51 and is used to determine the line of demarcation between crosstalk striped according to the color value of pixel in stereo-picture.Calculate son Unit 52 is used for according to the inclination angle for calculating the line of demarcation and obtaining the line of demarcation that subelement determines, using as the crosstalk item The inclination angle of line.Such as the stereo-picture of red green crosstalk striped shown in Fig. 4, region of the color value between 0 to 20 are red, face Region of the color value between 40 to 60 is green, then the pixel that color value is not belonging to the two sections in image can be recognized To be the pixel between crosstalk striped on line of demarcation.After obtaining the pixel on line of demarcation, Dip countion unit 33 can be with The line of demarcation is fitted by the methods of least square method or M algorithm for estimating, and calculates the line of demarcation between the crosstalk striped Inclination angle.

Further, in order to improve the computational accuracy at inclination angle, Dip countion unit 33 can calculate a plurality of in stereo-picture The inclination angle in line of demarcation, and average value is calculated, using the inclination angle as crosstalk striped.Such as the stereo-picture of Fig. 4, including five Line of demarcation, Dip countion unit 33 can find out the inclination angle in this five lines of demarcation respectively, then calculate inclining for this five lines of demarcation The average value at angle, so that but also calculated result is more acurrate.

It further, is that lines are synthesized using pixel when Dip countion unit 33 calculates line of demarcation, thus it is calculated As soon as the line of demarcation of crosstalk striped is it could also be possible that curved lines, the inclination angle for calculating this line of demarcation of at this moment having no idea, If a wrong numerical value will be obtained by being fitted lines using the methods of least square method and then being calculated inclination angle again.Therefore exist The linear distribution in the line of demarcation between the crosstalk striped can be detected before calculating the inclination angle in line of demarcation first with statistic algorithm. Fig. 6 is referred to, is the structure chart of another Dip countion unit of the embodiment of the present invention.Compared with Fig. 5, shown in Fig. 6 Dip countion unit 33 further includes linear detection sub-unit in addition to including that line of demarcation obtains subelement 51 and computation subunit 52 61.Linear detection sub-unit 61 is used for after line of demarcation acquisition subelement 51 obtains the line of demarcation, and statistics is utilized to calculate Method detects the linear distribution in the line of demarcation between the crosstalk striped.If linear detection sub-unit 61 detects that line of demarcation is straight Line is then calculated the inclination angle in line of demarcation by Dip countion unit 33 again.If detecting that line of demarcation is not straight line, directly give up pair The calculating at the line of demarcation inclination angle.

Specifically, it is assumed that the pixel coordinate sequence on stereo-picture crosstalk striped line of demarcation are as follows:

{ (x0, y0), (x1, y1), (x2, y2), (x3, y3) ... .. (xn, yn) },

Linear detection sub-unit 61 can judge its linear distribution by calculating the covariance matrix of this coordinate sequence. And calculating covariance matrix first will carry out decentralization to data, so the mean value (vector) of point sequence are as follows:

So covariance matrix are as follows:

Then linear detection sub-unit 61 can calculate the characteristic value E0 and E1 of covariance matrix, feature Distribution value generation at this time Table these pixels in a certain direction on the minimum and maximum variance of distribution that can reach, it is possible to by comparing maximum The ratio E0/E1 of characteristic value and minimal eigenvalue, carrys out the linear degree of judgment curves.A threshold value can be set, and (this threshold value is excellent Select numerical value 7), when the ratio E0/E1 of maximum eigenvalue and minimal eigenvalue is greater than the threshold value, so that it may think that the line of demarcation is Otherwise straight line is then determined as calculating of the curved lines without being included in crosstalk stripe angle.

If the calculated result of Dip countion unit 33 meets the vertical condition of crosstalk striped, parameter acquiring unit 34 Parameter value corresponding to current stereo-picture is recorded, for calculating optimal correction parameter.Crosstalk striped described here is vertical Condition be to calculate the most accurate situation of correction parameter, and in practical applications, can according to need to crosstalk stripe angle institute The set angle that need to meet makees specific range setting, such as the level inclination of crosstalk striped meets between 80 degree~100 degree, It is also assumed that the inclination angle of crosstalk striped meets preset angular range, it is not limited herein with it.The school of stereoscopic display device 22 Positive parameter includes angle correct parameter, the thick correction parameter of translational movement, grating pixel correction parameter, translational movement fine tuning parameter etc..

Since the light-splitting device of stereoscopic display device is slant setting in the light splitting list on display panel, on light-splitting device Member is arranged along a direction, and the display unit on display panel is arranged along another direction, the angle on the two directions An error being easy to produce when being assembly, if not being subject to correction angle degree error, can generate image inclination, hang angle, crosstalk, Granular sensation etc. influences the case where display effect, even and if angle correct parameter is used to correct this error.

The calculation of correction parameter can determine according to actual needs.Angle correct parameter and pixel correction are joined Number, the application provide two kinds of calculations.

Fig. 7 is referred to, is a kind of structure chart of parameter acquiring unit of the embodiment of the present invention.This parameter acquiring unit 34 It include: that reference value obtains subelement 71, linear relationship computation subunit 72 and angle pixel computation subunit 73.

Reference value obtains subelement 71 and is used to meet according to the inclination angle the multiple stereo-picture when predetermined angle range Corresponding multiple pixel-parameters obtain angle correct parameter reference values corresponding with the multiple pixel-parameters.Described here Pixel-parameters are preset, and are stored in stereoscopic display device, and stereoscopic display device is aobvious according to different pixel-parameters Show stereo-picture.And stereoscopic display device according to each pixel-parameters show stereo-picture when, all can to angle parameter into Row fine tuning, in this way analysis of the basis to the stereo-picture of display, so that it may find out, and crosstalk corresponding with each pixel-parameters Stripe angle meets the angle correct parameter reference values of predetermined angle range, to can be formed by pixel-parameters and angle correct One array of parameter reference values.

Linear relationship computation subunit 72 is used for the array according to the pixel-parameters and angle correct parameter reference values, meter Calculate the linear relationship of the pixel-parameters Yu angle correct parameter reference values.

Angle pixel computation subunit 73 is used for the linear pass according to the pixel-parameters and angle correct parameter reference values System, determines the corresponding angle correct parameter reference values of preset best pixel parameter, using as the corresponding perspective view in the inclination angle The angle correct parameter of picture.

As an example it is assumed that pitch parameter is pixel-parameters, cot parameter is angle correct parameter reference values, is set first One pitch parameter reference values makes stereoscopic display device show stereo-picture according to this preset pitch parameter reference values, Then the value for adjusting cot parameter, is changed the crosstalk stripe angle on stereo-picture, and calculates inclining for crosstalk striped in real time Angle.When calculating crosstalk striped is vertical state (or inclination angle meets preset angular range), then pitch at this time is recorded Parameter reference values and cot parameter reference values.Then another pitch parameter reference values is reset according to preset detection interval, And it is vertical by adjusting the crosstalk striped of the value of cot parameter to stereo-picture, and pitch parameter reference values and cot are recorded again Parameter reference values.And so on can be obtained by (pitch1, cot1), (pitch2, cot2), (pitch3, cot3), The array of (... ...).

And when searching for the cot parameter of above-mentioned (pitch, cot) array, search speed can also be accelerated using dichotomy. Fig. 8 is referred to, for using the schematic diagram of dichotomizing search pixel correction parameter.Wherein solid black lines are to take the inspection of cot parameter The inclination angle for the crosstalk striped that stereo-picture is shown when the both ends in rope section, i.e., in the case where pitch parameter reference values are selected, root According to the display panel of stereoscopic display device and the physical characteristic of light-splitting device, adjusts cot parameter and gone here and there on the stereo-picture that shows The gradient variation for disturbing striped is only possible between two black are realized.Three dotted lines are the retrieval areas for choosing cot parameter in Fig. 8 Between median when the crosstalk fringe inclination direction that shows, crosstalk item when wherein the dotted line of label 3 is target cot parameter reference values Line inclined direction.

When being started using dichotomizing search, the range of search is very wide, and retrieval section is the corresponding cot parameter of two black solid lines Between value, is attempted at the median first between the corresponding cot parameter value of two black solid lines, that is, select the void of label 1 The corresponding cot parameter value of line, then calculates the inclination angle of the dotted line of label 1 according to stereo-picture, and the dotted line of discovery label 1 compares right side Black solid line is closer vertical, therefore the region of search of cot parameter is updated to the corresponding cot parameter value of the black solid line in left side to label The corresponding cot parameter value of 1 dotted line.Then the centre of the corresponding cot parameter value of dotted line of left side black solid line to label 1 is chosen Then value, the i.e. corresponding cot parameter value of the dotted line of label 2 calculate the inclination angle of the dotted line of label 2, discovery mark according to stereo-picture Numbers 2 dotted line solid line more black than left side is closer to vertical, therefore the dotted line that the region of search of cot parameter is updated to label 2 is corresponding Cot parameter value to label 1 the corresponding cot parameter value of dotted line.Then the corresponding cot parameter value of dotted line for choosing label 2 arrives The median of the corresponding cot parameter value of the dotted line of label 1, the i.e. corresponding cot parameter value of the dotted line of label 3, by stereo-picture Crosstalk stripe angle calculate, discovery label 3 dotted line be it is vertical, then using the corresponding cot parameter value of the dotted line of label 3 as cot Parameter reference values record the array into (pitch, cot).It can be seen that can be greatly reduced using dichotomy in region of search choosing value Quantity improves search efficiency.

After obtaining (pitch, cot) array, the linear relationship of pitch and cot in array is calculated, Fig. 9 is referred to, is picture The linear relationship schematic diagram of plain correction parameter reference value and angle correct parameter reference values, wherein each dot is a logarithm Value, abscissa is pitch, and ordinate is cot, and Cong Tuzhong is it can also be seen that the array (pitch, cot) substantially meets straight line Linear relationship.Therefore, there are a following relationships between pitch and cot, it may be assumed that

Pitch=k*cot+b

Then the value of k and b are calculated.Finally according to the value of k, b, the grating physical gate of light-splitting device away from parameter t, optical splitter Part grating focal length parameter f and fixed position information (fixed position information refer to filming apparatus to stereoscopic display device away from From), and combine three-dimensional imaging optical principle select angle correct parameter reference values from array (pitch, cot), using as The angle correct parameter of stereoscopic display device.

Referring to Figure 10, it is the structure chart of another parameter acquiring unit of the embodiment of the present invention.This parameter obtains single Member 34 includes: that screening acquisition subelement 101 and analysis obtain subelement 102.

Screening obtain subelement 101 be used for obtain crosstalk striped inclination angle meet set angle range stereo-picture and Corresponding angle correct parameter.

Analysis obtains the stereo-picture that subelement 102 is used to meet set angle range to the inclination angle of crosstalk striped and carries out figure As analysis, the maximum stereo-picture of setpoint color accounting is obtained, and obtains corresponding pixel-parameters.

Specifically, it is assumed that pitch parameter is pixel-parameters, and cot parameter is angle correct parameter reference values, with Fig. 7's Unlike embodiment, cot parameter is adjusted first, value can be carried out to cot parameter using dichotomy, calculated vertical Body shows the inclination angle of crosstalk striped in the stereo-picture that show of equipment, when (or inclination angle meets preset angle to crosstalk striped vertically Spend range) when, cot parameter at this time is chosen as best cot parameter.Then cot parameter constant is selected, then to pitch parameter It is adjusted, and image analysis is carried out to the stereo-picture that stereoscopic display device is shown, it is maximum vertical to obtain setpoint color accounting Body image, and corresponding pitch parameter is obtained as best pitch parameter.Acquisition setpoint color accounting mentioned here is maximum Stereo-picture refer to that in pitch parameter tuning process, the width of crosstalk striped can gradually change, and work as crosstalk striped width When degree is maximum, pitch parameter at this time is chosen as best pitch parameter.At this moment the optimal display result of stereo-picture has two Kind of situation, it is assumed that crosstalk striped is red an IOU issued by a post office line, then when the width maximum of crosstalk striped, a kind of situation is the red or green of pure color Entire stereo-picture is taken, this expression has reached the target of correction.And another situation is that there was only one in stereo-picture The line of demarcation of crosstalk striped, and red green pure color occupies the both sides in line of demarcation respectively, this just needs subsequent correct again to translational movement to join Number is adjusted, to achieve the purpose that the color of pure color occupies entire stereo-picture.

The light-splitting device slant setting of stereoscopic display device is on display panel, due to the spectrophotometric unit of light-splitting device and aobvious Show that the display unit arrangement period of panel mismatches the translational movement error that can generate, the translational movement correction parameter (including it is flat The thick correction parameter of shifting amount and translational movement finely tune parameter) be exactly can if be not corrected in order to correct this translational movement error Stereo-picture is set to lead to the problem of picture crosstalk.

Furthermore, it is understood that in the case where angle correct parameter has obtained, stereoscopic display device according to acquisition angle Correction parameter shows stereo-picture, may possibly still be present a plurality of crosstalk striped on stereo-picture at this time, the reason is that due to string The width for disturbing striped is less than display area, although still having three in display area so that crosstalk striped state in a vertical shape Crosstalk striped more than item.

In response to this, the scheme that the application uses is: the central point of crosstalk striped is adjusted to by progress coarse adjustment first Then the center of display area increases width of the width of crosstalk striped until being greater than or equal to display area, finally again It is finely adjusted, the pure color of setting is made to occupy entire display area.

Figure 30 is referred to, is a kind of structure chart of parameter acquiring unit of the embodiment of the present invention.This parameter acquiring unit 34 include that central point detection sub-unit 311 and thick translation parameters obtain subelement 312.Central point detection sub-unit 311 is for sentencing Whether the central point of crosstalk striped is in the central area of the screen area on disconnected stereo-picture.It is single that thick translation parameters obtains son Member 312 is for obtaining corresponding translational movement parameter when the center of crosstalk striped is when the central area of the screen area As the thick correction parameter of the translational movement.

Specifically, the central area refers to abscissa range certain in screen area, such as in screen area The abscissa of line is 5, then this region can be (4,6).Translational movement parameter is adjusted in preset section, and can use figure As analytical technology, the stereo-picture that stereoscopic display device is shown is analyzed.If there is at least three crosstalks on stereo-picture Whether striped, the then central point for detecting corresponding crosstalk striped are in the central area of on-screen display (osd) area, such as the perspective view Seem left view, pure green image should be shown under ideal display state, then finds out all green crosstalk stripeds on the stereo-picture Central point, and detect whether the center of some green crosstalk striped in the central area of screen area.If there is The center of one green crosstalk striped is in the central area of screen area, then using translational movement parameter at this time as translational movement Thick correction parameter.If obviously there are two crosstalk stripeds on stereo-picture, illustrate that the central point of crosstalk striped at this time is necessarily inclined Central area from screen area, by adjusting translational movement parameter, translate crosstalk striped gradually, until a crosstalk striped Center in the central area of screen area, and by record translational movement parameter be at this time the thick correction parameter of translational movement；Or Person is until the color of a crosstalk striped then illustrates to have reached correction purpose at this time full of entire screen area, and record is at this time Translational movement parameter be the thick correction parameter of translational movement.

When the central point of crosstalk striped on stereo-picture is located at the central area of screen area, then need to judge the crosstalk item Whether the width of line covers the screen area, if the width of crosstalk striped is not covered with the screen area, can lead to Adjustment pixel-parameters are crossed to increase the width of crosstalk striped, until the width cover screen region of crosstalk striped.

Figure 31 is referred to, is a kind of structure chart of parameter acquiring unit of the embodiment of the present invention, this parameter acquiring unit 34 include that width of fringe detection sub-unit 321 and grating pixel-parameters obtain subelement 322.Width of fringe detection sub-unit 321 For judging whether the width of the crosstalk striped covers the screen area.Grating pixel-parameters obtain subelement 322 and are used for When the width of crosstalk striped covers the screen area, perspective view when by the crosstalk striped covering screen area The corresponding grating pixel-parameters of the pixel-parameters of picture are as the grating pixel correction parameter.

Specifically, by adjusting pixel-parameters in preset section, the stereo-picture for showing stereoscopic display device The width of middle crosstalk striped constantly changes, and when the width of crosstalk striped is greater than or equal to the width of screen area, that is, goes here and there It disturbs striped and covers screen area, recording the corresponding grating pixel-parameters of the pixel-parameters is grating pixel correction parameter.It calculates It can be according to following formula when grating pixel correction parameter:

D/ (d+f)=t0/pitch,

Wherein, d is the fixed position information of the stereoscopic display device, and pitch is that the width of the crosstalk striped covers The pixel-parameters of the stereo-picture when screen area, f are the light of the light-splitting device of the preset stereoscopic display device Grid focal length parameter, t0 are the grating pixel-parameters of the light-splitting device of the stereoscopic display device, and as grating pixel school Positive parameter.

Further, during adjusting pixel-parameters, the variation between pixel-parameters and crosstalk width of fringe is linearly closed System's parabolically shape, thus crosstalk width of fringe just cover screen region when, grating pixel-parameters obtain subelement and can obtain Obtain two pixel-parameters values, i.e. the first pixel-parameters and the second pixel-parameters.Theoretically when being adjusted to the first pixel-parameters and When the average value of two pixel-parameters, the width of crosstalk striped reaches maximum, therefore grating pixel-parameters obtain subelement and can count The average value for calculating first pixel-parameters and second pixel-parameters, using the calculated average value as the crosstalk Striped covers grating pixel correction parameter described in the pixel-parameters of the stereo-picture when screen area.

After obtaining grating pixel correction parameter, in order to further eliminate the essence for calculating error and further increasing correction True property, can again be finely adjusted translational movement.

Referring to Figure 11, it is a kind of structure chart of parameter acquiring unit of the embodiment of the present invention.This parameter acquiring unit 34 include: that micro- translation parameters obtains subelement 111.Micro- translation parameters obtains subelement 111 and is used for according to calculated image string Disturb the translational movement fine tuning parameter that scoring obtains corresponding stereo-picture.The value interval that translational movement finely tunes parameter can be with acquisition The thick correction parameter of translational movement is median, and left and right one range of each setting determines.The picture crosstalk scoring refers to opposition The evaluation criteria of body picture crosstalk situation.

Specifically, adjustment translational movement is usually to have corrected that carry out in the case where completion in angle correct parameter, false If xoffadd parameter is translational movement fine tuning parameter, crosstalk striped is that red an IOU issued by a post office line is made by suitably adjusting xoffadd parameter The picture of stereo-picture translates in the horizontal direction, when moving to a suitable numerical value, image that left and right camera grabs Most bright-coloured red and green are presented respectively.This suitable parameter is exactly optimal xoffadd parameter.

When stereoscopic display device shows stereo-picture using best xoffadd parameter, two cameras in left and right are taken Stereo-picture is the red and green image of pure color respectively, and red and green be respectively filled with whole image region, no extension angle, such viewer When observing stereo-picture, optimal 3D effect can be experienced.

The correction course of xoffadd parameter is directly to traverse maximum from the minimum value of the xoffadd parameter of detection interval Value, the xoffadd parameter for then therefrom selecting a spectrophotometric result best.It can be can be changed with one to accelerate the speed of search Step-length be adjusted.

For example, increasing a numerical value every time, then to stereoscopic display device since initial translational movement xoffadd=0 It is configured.After being configured every time to equipment, stereo-picture is grabbed by filming apparatus immediately, then utilizes image analysis Technology analyzes the color of stereo-picture, and is adjusted according to color change situation to step-length, here can be according to stereo-picture The color value of upper pixel sets a crosstalk scoring, is carried out according to change step of the crosstalk scoring situation to xoffadd parameter Adjustment.Such as stereo-picture crosstalk scoring it is very low, illustrate it is far apart from best xoffadd parameter value, so needing to increase by one A bigger numerical value, to accelerate search speed., whereas if the crosstalk scoring of stereo-picture is higher, illustrate close to best Xoffadd parameter value, so the xoffadd parameter value that one step-length of setting is smaller, with precise search.When the crosstalk of image is commented It assigns to up to after certain threshold value, xoffadd parameter at this time can be stored in an array, finally be found out from this array One optimal xoffadd parameter.

Because the stereo-picture that stereoscopic display device provides is there are two images of left view and right view, referring to Figure 12, Figure 12 is the schematic diagram of the best viewing location of stereo-picture, according to optical imaging concept, only when the left camera of filming apparatus It is individually positioned in optimal viewing point with right camera, i.e. circled positions in Figure 12 can just see most bright-coloured stereo-picture, institute With the difference according to filming apparatus apart from stereoscopic display device distance, optimum value is selected from multiple candidate's xoffadd parameter values It can be there are two types of scheme:

The first, when two cameras of filming apparatus are located at optimum position, micro- translation parameters obtains subelement 111 and obtains It takes picture crosstalk to score translational movement parameter corresponding to highest stereo-picture as optimal translational movement and finely tunes parameter.Such case Under, when the image that left side camera is captured is most bright-coloured, the image on the right should also be most bright-coloured, so left and right is three-dimensional Image is to reach most bright-coloured degree simultaneously.Best xoffadd parameter at this time is to make the left side (or the right) image Most bright-coloured xoffadd parameter value.It at this time only need to be according to the image that a camera acquires it may determine that optimal out Xoffadd parameter.

Second, when two cameras of filming apparatus are not located at optimum position, specifically, when two cameras When not all being placed on optimal optics viewing location or two cameras are all before optimum position or two are taken the photograph As head is all placed on behind best viewing location, 3 and Figure 14, Figure 13 are that camera is placed on best viewing position referring to Figure 1 Subsequent schematic diagram is set, Figure 14 is that camera is placed on the schematic diagram before best viewing location.At this moment it is possible that: the left side Camera has grabbed most bright-coloured solid-color image, but the image that the right camera is captured but is not most bright-coloured pure color Image, or just on the contrary, right image has detected that most bright-coloured solid-color image, and the left side be also not detected it is most bright-coloured pure Chromatic graph picture.In this case, micro- translation parameters obtains subelement 111 and constitutes one according to the xoffadd parameter being stored in array A selection region, and the median of this selection region is obtained as optimal xoffadd parameter.And it is chosen from selection region Optimal xoffadd parameter can use different schemes, and the present embodiment provides three kinds of preferred embodiments:

(1) if the image that left and right camera grabs when reaching most bright-coloured corresponding xoffadd parameter differ very little, As shown in figure 15, Figure 15 is that a kind of translational movement of selection finely tunes the curve synoptic diagram of parameter array, and abscissa is in Figure 15 Xoffadd parameter value, ordinate are crosstalk score value, and two curves are left view and the corresponding xoffadd ginseng of right view respectively The curve of number array, when the right and left image at this moment can be taken to reach most bright-coloured degree (i.e. ordinate is maximum) respectively The average value of xoffadd parameter takes the xoffadd parameter conduct of dotted line position in Figure 15 as optimal xoffadd parameter Best xoffadd parameter.

(2) if the image that left and right camera grabs when reaching most bright-coloured corresponding xoffadd parameter difference it is larger, As shown in figure 16, abscissa is xoffadd parameter value in Figure 16, and ordinate is crosstalk score value, lesser two curves of peak value It is the curve of left view and the corresponding xoffadd parameter array of right view respectively, at this moment takes the xoffadd of left view and right view Xoffadd parameter corresponding to the maximum value of the sum of the ordinate value of parameter curve is optimal xoffadd parameter, i.e., by two Curve ordinate is added, and forms the higher curve of peak value in Figure 16, then takes the maximum value of this curve ordinate corresponding Abscissa be chosen to be optimal xoffadd parameter.

(3) 7, Figure 17 is that the translational movement that another is chosen finely tunes the curve synoptic diagram of parameter array, Figure 17 referring to Figure 1 Middle abscissa is xoffadd parameter value, and ordinate is crosstalk score value, and two curves are that left view and right view are corresponding respectively The curve of xoffadd parameter array.An ordinate threshold value (as shown in threshold line in Figure 17) is set, four abscissas are filtered out (i.e. tetra- abscissas of A, B, C, D), then take the median of abscissa B, C or take the median of abscissa A, D as optimal Xoffadd parameter.

It is worth noting that, for different stereoscopic display devices, it can be according to the specific of the stereo-picture shown to it It analyzes to select calculative correction parameter, and it is not absolutely required to carry out a calculating to each correction parameter.Example Such as when stereo-picture only has two vertical crosstalk stripeds, and the width of crosstalk striped is maximum, then only needing to calculate flat Shifting amount correction parameter is without calculating angle correct parameter.It is three-dimensional for another example after stereo-picture calculates angle correct parameter The stereo-picture that display equipment is shown according to the two correction parameters then no longer needs to calculate translational movement correction parameter in pure color.

The application obtains correction parameter using the inclination angle of crosstalk striped, and the accuracy for the correction parameter being calculated is high, And correction efficiency can be greatly improved.

Further, referring to Figure 19, it is a kind of structure chart of image analyzing unit of the embodiment of the present invention.This image Analytical unit further comprises: crosstalk scoring computation subunit 191.Crosstalk scores computation subunit 191 for according to described vertical The color of body image calculates picture crosstalk scoring.The crosstalk scoring computation subunit 191 can be by the stereo-picture Color value carry out subregion statistics, further according to the color value section of different zones, assign corresponding weight to different zones, so Summation and weighted sum are carried out to the color value of all areas afterwards, finally by the sum of all weighted color values and all colours value Sum ratio as picture crosstalk score.

Specifically, many places require to detect the cross talk conditions of stereo-picture in this application, such as micro- flat Shifting parameter obtains subelement 111 and just needs picture crosstalk scoring to judge whether stereo-picture is solid-color image, the image Crosstalk scoring is an evaluation criterion to three-dimensional picture crosstalk degree, if the region that solid color occupies stereo-picture is got over It is more, and color is more bright-coloured, then the picture crosstalk scoring of the stereo-picture is higher.

By taking red as an example, when judging the bright-coloured degree of red pixel, subregion statistics is carried out to the color value of image, if The color value of most of pixel all concentrates near color value 0, then can be concluded that image belongs to very bright-coloured red.According in this way Method can determine the bright-coloured degree of the entirety of image.It specifically, can be to picture on image when needing to judge red image The color value of vegetarian refreshments does a subregion weighted sum, the color value weighted sum of all pixels point divided by unweighted numerical value With, using this numerical value as pair stereo-picture crosstalk evaluate.So-called subregion weighting, refers to closer to most hunting pink The color value of (most hunting pink color value is 0) assigns bigger weight, for example the numerical value in the section color value (0-5) is summed so Afterwards multiplied by a biggish weight 64, the numerical value in the section color value (5-10) is summed multiplied by a weight 16, color value (10-15) The numerical value in section and multiplied by a small weight 4, the numerical value summation in the section color value (15-20) remains unchanged, and weighted sum is removed With unweighted and available one 1 to 64 numerical value, the evaluation of a degree of crosstalk can be made to image of this numerical value. The stereo-picture of green is also handled in this way, available one judgement to the bright-coloured degree of green.

The detection interval of setting may include section size, parameter adjusting step etc..And in correction course, angle correct parameter, light Grid pixel correction parameter, translational movement coarse adjustment parameter, translational movement fine tuning correction parameter etc. require to carry out reference value detection interval Setting.Such as when correcting translational movement, it is (including flat that translational movement correction parameter is arranged by detection interval setting unit 211 first The thick correction parameter of shifting amount and translational movement finely tune parameter) detection interval and detection interval in value step-length, and by setting Detection interval is sent to micro- translation parameters and obtains subelement 111, and then micro- translation parameters obtains subelement 111 according to receiving Stereo-picture and parameter reference values corresponding in detection interval, obtain optimal translational movement correction parameter.
