Refer to Fig. 2, it is a kind of Organization Chart of the correction system of stereoscopic display device of the embodiment of the present invention, and it includes the correction parameter acquisition device 21 of stereoscopic display device 22, filming apparatus 23 and stereoscopic display device.Stereoscopic display device 22 is used for showing stereo-picture, filming apparatus 23 are used for shooting the image frame including stereoscopic display device 22 display screen, and the image frame that obtains will be shot it is sent to the correction parameter acquisition device 21 of stereoscopic display device, the correction parameter acquisition device 21 of stereoscopic display device is processed to the image frame receiving, determine the screen area of image frame Stereo display equipment 21, and calculate the inclination angle of the crosstalk striped of screen area neutral body image, and when inclination angle falls into predetermined angle scope, obtain the correction parameter of stereoscopic display device 22, this correction parameter is used for correcting the rigging error of stereoscopic display device 22.When user opens stereoscopic display device 22, stereoscopic display device 22 corrects rigging error according to correction parameter, eliminates the harmful effect to stereoscopic display device 22 display effect for the rigging error, thus lifting the display effect of stereoscopic display device.

In the present embodiment, stereoscopic display device 22 can be the electronic installation that mobile terminal or computer etc. have display function, and the correction parameter acquisition device 21 of stereoscopic display device can be that computer or mobile terminal etc. carry the equipment processing with communication function.In the present embodiment, the correction parameter acquisition device 21 of preferably stereoscopic display device is computer, stereoscopic display device 22 is connected with the correction parameter acquisition device 21 of stereoscopic display device by data wire, and filming apparatus 3 are connected with the correction parameter acquisition device 21 of stereoscopic display device by data wire.

Filming apparatus 23 can include at least one photographic head, and photographic head shoots the stereo-picture of stereoscopic display device 22 display.In the present embodiment, filming apparatus 23 include spaced left photographic head 24 and right photographic head 25, and left photographic head 24 is all identical with the structure of right photographic head 25, physical property.Spacing between left photographic head 24 and right photographic head 25 is preferably human eye interpupillary distance, meets three-dimensional imaging requirement.

Tracking equipment (in figure does not illustrate) can be installed on stereoscopic display device 22, tracking equipment is used for measuring the distance that filming apparatus 23 arrive stereoscopic display device 22, tracking equipment can be for example to follow the tracks of photographic head.It is identified for the ease of stereoscopic display device 22, filming apparatus 23 can be faceform, and above-mentioned two photographic head is separately mounted to the right and left eyes position of faceform.

Specifically, stereoscopic display device 22 is successively set on multiple fixed positions by the system of this enforcement, the distance of these fixed positions to filming apparatus 23 is different, the stereo-picture that each fixed position is photographed by filming apparatus 23 successively is respectively transmitted to the correction parameter acquisition device 21 of stereoscopic display device, and the correction parameter of stereoscopic display device 22 is obtained by the correction parameter acquisition device 21 of stereoscopic display device, so that stereoscopic display device 22 can be corrected using the correction parameter of this acquisition, and then improve stereo display effect.

Wherein, the fixed position residing for stereoscopic display device 22 can be configured as needed, and in the present embodiment, fixed position preferably employs linear or cross-shaped arrangement, as shown in figs. 30 and 31.In Figure 30, fixed position 301 adopts linear array.In Figure 31, fixed position 401 adopts cross-shaped arrangement, and from unlike linear, wide viewing angle is also brought in the limit of consideration of correction by the criss-cross arrangement mode of fixed position, and the reliability of correction is higher.Certainly, the set-up mode of fixed position can also adopt other arrangement modes, for example circular, and rectangle is not limited thereto here.

In trimming process, can be to change the fixed position residing for stereoscopic display device in the form of slide rail, i.e. laying sets the slide rail (such as linear or cross) of shape in advance, then stereoscopic display device 22 is placed on slide rail and moves along slide rail, and fix in the fixed position setting successively.It is of course also possible to move, equally can realize the purpose of fixed position change using filming apparatus 23 are installed on slide rail.

In the present embodiment, the stereo-picture that stereoscopic display device 22 provides includes the stereo-picture with image difference, for example, have left view and the right view of image difference.For ease of identification and detection, left view and right view can be all solid-color image, but left view is different with right view color.For example, left view is the first color image, and right view is the second color image.The color of the first color image and the second color image is different.Therefore, the axonometric chart with image difference can be red green axonometric chart, black/white axonometric chart, or has other two different colors of solid-color image.Certainly, the stereo-picture of the left and right view that embodiment of the present invention provides is determined by stereoscopic display device 22, is not limited with solid-color image.

Before correction, lead to the phenomenons such as picture crosstalk due to rigging error, cause often all to comprise crosstalk striped in left view and right view, described crosstalk striped refers to it should is to be shown to, in the pattern set on left view and two images of right view, the striped cause on an image originally, and such as image is to be made up of a plurality of red streak and green color stripe interval.And one of main purpose of present invention correction is exactly to eliminate these crosstalk stripeds, make left view and right view all assume the image of its script, for example above-mentioned pie graph picture is spaced by a plurality of red streak and green color stripe, corrected after, left view is in pure red image, and right view is in pure green image.For convenience of description, the crosstalk striped in present embodiment all to illustrate taking red an IOU issued by a post office stricture of vagina as a example.

When stereoscopic display device 22 is located at least two different fixed position information, filming apparatus 23 shoots respectively stereoscopic display device 22 positioned at two fixed positions when image frame, and this image frame is sent to correction parameter acquisition device 21.Correction parameter acquisition device 21 is according to the image frame receiving, detection crosstalk striped simultaneously calculates stripe angle, when the stripe angle of the corresponding stereo-picture of at least two fixed position information that calculate meets predetermined angle scope, then obtain the correction parameter of stereoscopic display device 22, for correcting this stereoscopic display device 22.

For example, if stereoscopic display device 22 is located at the first fixed position information, filming apparatus 23 shooting stereoscopic display device is located at image frame during the first fixed position, and sends correction parameter acquisition device 21 to.If after the correction parameter acquisition device 21 of stereoscopic display device receives the image frame that filming apparatus 23 transmission comes, can determine whether the screen area of this image frame Stereo display equipment, and obtain the stereo-picture that screen area shows, utilize image analysis technology to detect the crosstalk striped on stereo-picture simultaneously.If there is not crosstalk striped on stereo-picture, illustrate that this stereo-picture is normal display it is not necessary to correct.And if crosstalk striped is existed on stereo-picture, then the correction parameter acquisition device 21 of stereoscopic display device can calculate the inclination angle of crosstalk striped, and the correction parameter of the corresponding stereo-picture in this inclination angle is obtained when predetermined angle scope is met according to the inclination angle of crosstalk striped, then change the fixed position information of stereoscopic display device 22, for example the second fixed position information is moved to by the first fixed position information, then the method being located at the correction parameter of the corresponding stereo-picture in the first fixed position information inclination angle according still further to acquisition stereoscopic display device 22, obtain the correction parameter of the corresponding stereo-picture in inclination angle when stereoscopic display device is located at the second fixed position information.By that analogy, it is possible to obtain stereoscopic display device 22 is located at the correction parameter of corresponding stereo-picture during multiple fixed position, and the plurality of correction parameter is selected and calculates, thus obtaining the correction parameter of stereoscopic display device, to correct stereoscopic display device 22.Correction parameter for the application stereoscopic display device to be obtained, some correction parameters are in single fixed position, can obtain during any one fixed position that i.e. stereoscopic display device 22 is located therein, such as angle correct parameter and some correction parameters are to need could obtain using many fixed positions, such as grating pixel correction parameter, grating focus correction parameter etc..Below, it will describe the acquisition process of each correction parameter of stereoscopic display device in detail.

In the embodiment of the present invention, the stripe angle of crosstalk striped refers to：Crosstalk striped and the angle of horizontal direction, or the angle of crosstalk striped and vertical direction.When the angle that the inclination angle of crosstalk striped is crosstalk striped and horizontal direction, the predetermined angle of crosstalk striped may range from [- 90 °, -70 °] or [70 °, 90 °], if now the inclination angle of crosstalk striped falls into above-mentioned interval, then think that the stereo-picture crosstalk striped that now stereoscopic display device shows is in vertically, obtain the correction parameter of the corresponding stereo-picture in inclination angle of this crosstalk striped simultaneously.When the angle that the inclination angle of crosstalk striped is crosstalk striped and vertical direction, the predetermined angle of crosstalk striped may range from [- 20 °, 0 °] or [0 °, 20 °], if now the inclination angle of crosstalk striped falls into above-mentioned interval, then think that on the stereo-picture that now stereoscopic display device shows, crosstalk striped is in vertically, obtain the correction parameter of the corresponding stereo-picture in inclination angle of this crosstalk striped simultaneously.

Refer to Fig. 3, it 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, computing unit 33 and parameter acquiring unit 34.

Image acquisition unit 31 is used for obtaining the stereo-picture of described stereoscopic display device 22 display.In trimming process, generally require the display parameters of stereoscopic display device 22 repeatedly to be adjusted, to find out optimal parameter.And filming apparatus 23 can be tracked shooting to the image frame including stereoscopic display device 22 display screen in real time, and the image frame photographing is sent to image acquisition unit 31.

Image acquisition unit 31 obtains the stereo-picture of stereoscopic display device 22 display from the image frame receiving, and with the change of image when obtaining parameter adjustment each time, and the stereo-picture getting is sent to crosstalk fringe detection unit 32.

Because the image frame that filming apparatus 23 obtain not only includes the stereo-picture that stereoscopic display device shows, also has the external environment condition including beyond viewing area, for avoiding the accuracy of external environment influence correction parameter, need image acquisition unit 31 before obtaining stereo-picture, the viewing area of image frame Stereo display equipment 22 need to be determined first, to determine the stereo-picture of the display in viewing area.

Specifically, image acquisition unit 31 includes receiving subelement and determination subelement.Wherein, receiving subelement is used for receiving the image frame of described stereoscopic display device 22 display screen of inclusion that filming apparatus 23 photograph；Determination subelement is used for determining the screen area of the image frame Stereo display equipment 22 of receiving subelement reception, and obtains the stereo-picture that described screen area shows.Determination subelement can extract the image channel value in viewing area using image analysis technology, then using rim detection, detect boundary point and the boundary curve of viewing area, in conjunction with image area, detect viewing area.

Further, refer to Figure 20, determination subelement includes：Brightness of image analysis subelement 204, binary conversion treatment subelement 201, range searching subelement 202 and merger divide subelement 203.

Brightness of image is analyzed subelement 204 and is used for obtaining the brightness value of pixel in image frame.

Binary conversion treatment subelement 201 is used for carrying out binary conversion treatment according to default luminance threshold to stereo-picture, and to obtain corresponding quasi- screen area, described predetermined luminance threshold value has at least two.The binaryzation of so-called image is it is simply that be set to 0 or 255 by the gray value of the pixel on image, that is, whole image is presented significantly only black and white visual effect.Such that it is able to generally tell screen area.

Range searching subelement 202 is used for the region that search on the quasi- screen area after binary conversion treatment sets shape.The described region setting shape can be rectangular area, border circular areas.Delta-shaped region etc., is defined according to the source stereotome in stereoscopic display device.

Merger divides subelement 203 and is used for the region of the setting searching shape being carried out merger division, to determine the screen area of stereoscopic display device described in described image picture.The quantity of the setting regions that range searching subelement 202 searches out might have a lot, and these setting regions may vary, and position is probably overlapping, interlocking, separate each other.The process of merger can be that the coincidence number of times in the region searching out according to these gives weighted value, and that is, the number of times of certain area coincidence more at most gives a higher weight.Divide process refer to according to merger after region weight distribution, remove weight be less than certain value region, and again mark off set shape region, as screen area.

Crosstalk fringe detection unit 32 is used for detecting the crosstalk striped in described stereo-picture.Crosstalk fringe detection unit 32 can obtain the crosstalk striped in stereo-picture by calculating the color value of pixel in stereo-picture.For example, can be by by stereoscopic image conversion to HSV space, obtaining the value on color component, HSV space is to embody a kind of color space of color intuitive nature, also referred to as hexagonal pyramid model (Hexcone Model), has three color parameters respectively in this color space：Tone (Hue), saturation (Saturation) and brightness (Value).For red green crosstalk striped, region between 0 to 20 for the color value is red, and region between 40 to 60 for the color value is green, so it is known that distribution of color on stereo-picture, thus detecting on stereo-picture with the presence or absence of crosstalk striped.In conjunction with referring to Fig. 4, it is a stereo-picture to be corrected, and wherein black region represents red, and white space represents green, and as can be seen from Figure 4 this stereo-picture has three red six crosstalk stripeds of Three Greens.

Dip countion unit 33 is used for calculating the stripe angle of the described crosstalk striped detecting.It can be seen from figure 4 that crosstalk striped is often tilt, and whole trimming process, if with continuous image to embody, the width exactly making crosstalk striped in image becomes larger to reduce the quantity of crosstalk striped, then translates, till single tone occupies viewing area.And the spectrophotometric result in order to reach, and (extension angle refers to that on stereo-picture, certain region does not have display pattern to prevent appearance on stereo-picture from hanging angle, such as one pure red rectangle stereo-picture, one angle does not show red pattern), the present embodiment obtains correction parameter using in the case that crosstalk striped is vertical by parameter acquiring unit 34, to reach preferable display effect and correction efficiency.It is of course also possible to using obtaining correction parameter in the case of crosstalk jail-bar level, the application is not limited thereto.

Further, Dip countion unit 33 by obtaining the demarcation line between crosstalk striped, and can calculate described marginal inclination angle, using the inclination angle as described crosstalk striped.Refer to Fig. 5, it is a kind of structure chart of Dip countion unit of the embodiment of the present invention.This Dip countion unit 33 further includes that demarcation line obtains subelement 51 and computation subunit 52.Demarcation line obtains subelement 51 and is used for determining the demarcation line between crosstalk striped according to the color value of pixel in stereo-picture.Computation subunit 52 is used for according to calculating the described marginal inclination angle that described demarcation line acquisition subelement 51 determines, using the inclination angle as described crosstalk striped.The stereo-picture of the red green crosstalk striped for example shown in Fig. 4, region between 0 to 20 for the color value is red, region between 40 to 60 for the color value is green, then in image, color value is not belonging to this two interval pixels and may be considered the pixel on demarcation line between crosstalk striped.After obtaining the pixel on demarcation line, Dip countion unit 33 can simulate this demarcation line by the method such as method of least square or M algorithm for estimating, and calculates the marginal inclination angle between described crosstalk striped.

Further, in order to improve the computational accuracy at inclination angle, Dip countion unit 33 can calculate a plurality of marginal inclination angle in stereo-picture, and calculates meansigma methodss, using the inclination angle as crosstalk striped.The stereo-picture of such as Fig. 4, including five demarcation line, Dip countion unit 33 can obtain this five marginal inclination angles respectively, then calculates the meansigma methodss at this five marginal inclination angles, thus also making result of calculation more accurate.

Further, it is to fit to lines using pixel that Dip countion unit 33 calculates during demarcation line, thus the demarcation line of the crosstalk striped calculating it could also be possible that one bending lines, at this moment just have no idea to calculate this marginal inclination angle, if simulating lines using methods such as method of least square, then calculating inclination angle again will obtain a wrong numerical value.The marginal wire distribution between described crosstalk striped can be detected first with statistic algorithm therefore before calculating marginal inclination angle.Refer to Fig. 6, it is the structure chart of another kind of Dip countion unit of the embodiment of the present invention.Compared with Fig. 5, the Dip countion unit 33 shown in Fig. 6 obtains subelement 51 and computation subunit 52 except including demarcation line, also includes wire detection sub-unit 61.Wire detection sub-unit 61 is used for, after described demarcation line acquisition subelement 51 obtains described demarcation line, whether meeting default linear distribution condition using the wire distribution that statistic algorithm detects the lines that matching obtains.If wire detection sub-unit 61 detects that demarcation line meets default linear distribution condition, such as demarcation line is straight line, then calculate marginal inclination angle by Dip countion unit 33 again.If detecting that demarcation line is unsatisfactory for condition, directly give up the calculating to this demarcation line inclination angle.

Specifically it is assumed that the pixel coordinate sequence on stereo-picture crosstalk striped demarcation line is：

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

Wire detection sub-unit 61 can judge its linear distribution by calculating the covariance matrix of this coordinate sequence.And calculate covariance matrix and will first data be carried out with decentration, so the average (vectorial) of point sequence is：

So covariance matrix is：

Then wire detection sub-unit 61 can calculate eigenvalue E0 and E1 of covariance matrix, feature Distribution value now represents the minimum and maximum variance of the distribution that these pixels can reach on some direction, so the linear degree of judgment curves can be carried out by comparing the ratio E0/E1 of eigenvalue of maximum and minimal eigenvalue.A threshold value (this threshold value preferred value 7) can be set, when the ratio E0/E1 of eigenvalue of maximum and minimal eigenvalue is more than this threshold value, just it is considered that this demarcation line is straight line, otherwise then it is judged to that the lines bending do not include the calculating of crosstalk stripe angle.

If the result of calculation of Dip countion unit 33 meets the vertical condition of crosstalk striped, then parameter acquiring unit 34 records the corresponding parameter value in current stereo-picture inclination angle, for calculating optimal correction parameter.The vertical condition of crosstalk striped described here is to calculate the most accurate situation of correction parameter, and in actual applications, as needed specific range set can be made to the set angle meeting needed for crosstalk stripe angle, the level inclination of such as crosstalk striped meets between 80 degree～100 degree, it is also assumed that the inclination angle of crosstalk striped meets default angular range, here is not limited with it.The correction parameter of stereoscopic display device 22 includes angle correct parameter, grating pixel correction parameter, grating focus correction parameter, the thick correction parameter of translational movement, translational movement fine setting parameter etc..Wherein, the thick correction parameter of translational movement is one of correction stereoscopic display device process intermediate parameters, and the purpose obtaining this parameter is to obtain the grating pixel correction parameter of stereoscopic display device, grating focus correction parameter.

Because the light-splitting device of stereoscopic display device is slant setting on display floater, spectrophotometric unit on light-splitting device arranges along a direction, display unit on display floater arranges along another direction, angle in this both direction is the error easily producing during assembling, if not correction angle degree error in addition, the situation that image tilts, hangs the impact display effect such as angle, crosstalk, granular sensation then can be produced, even and if angle correct parameter is used for correcting this error.

The calculation of correction parameter can determine according to actual needs.It should be noted that by obtain stereoscopic display device angle parameter when it is only necessary to stereoscopic display device 22 be located at a fixed position when just can obtain.Therefore, in concrete acquisition, obtain the angle correct parameter of stereoscopic display device when stereoscopic display device 22 is located at arbitrary fixed position.For the angle correct parameter of stereoscopic display device, the application provides two kinds of calculations, is described more fully below.

Refer to Fig. 7, it is a kind of structure chart of parameter acquiring unit of the embodiment of the present invention.This parameter acquiring unit 34 includes：Reference value obtains subelement 71, linear relationship computation subunit 72 and angle pixel computation subunit 73.

Reference value obtains subelement 71 and is used for meeting multiple pixel-parameters corresponding to the plurality of stereo-picture during predetermined angle scope according to described inclination angle, obtains angle correct parameter reference values corresponding with the plurality of pixel-parameters.Stereoscopic display device shows stereo-picture according to different pixel-parameters.And when stereoscopic display device shows stereo-picture according to each pixel-parameters, angle parameter will be finely adjusted, analysis so according to the stereo-picture to display, just can find out corresponding with each pixel-parameters, and crosstalk stripe angle meets the angle correct parameter reference values of predetermined angle scope, thus can be formed by an array of pixel-parameters and angle correct parameter reference values.

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

Angle pixel computation subunit 73 is used for the fixed position information (fixed position information refers to filming apparatus to the distance of stereoscopic display device) according to described pixel-parameters and the linear relationship, grating physical parameter t of the light-splitting device of stereoscopic display device and default grating focal length parameter f1 and described stereoscopic display device of angle correct parameter reference values, and the optical principle of three-dimensional imaging, from array (pitch, cot optimal angle correct parameter reference values are selected in), using the angle correct parameter as described stereoscopic display device.

For example, hypothesis pitch parameter is pixel-parameters, cot parameter is angle correct parameter reference values, set pitch parameter reference values first, make stereoscopic display device according to this pitch parameter reference values display stereo-picture setting, then adjust the value of cot parameter, so that the crosstalk stripe angle on stereo-picture is changed, and calculate the inclination angle of crosstalk striped in real time.When calculating crosstalk striped and being vertical state (or inclination angle meets default angular range), then record pitch parameter reference values now and cot parameter reference values.Then according to default detection interval resets another pitch parameter reference values and vertical to the crosstalk striped of stereo-picture by adjusting the value of cot parameter, and record pitch parameter reference values and cot parameter reference values again.Can be obtained by (pitch1, cot1) by that analogy, (pitch2, cot2), (pitch3, cot3), the array of (... ...).

And when searching for the cot parameter of above-mentioned (pitch, cot) array, it would however also be possible to employ two way classification accelerates search speed.Refer to Fig. 8, it is the schematic diagram using dichotomizing search pixel-parameters.Wherein solid black lines are the inclination angles of the crosstalk striped that stereo-picture the shows during two ends in retrieval interval taking cot parameter, i.e. in the case that pitch parameter reference values are selected, display floater according to stereoscopic display device and the physical characteristics of light-splitting device, the gradient change of crosstalk striped on the stereo-picture adjusting cot parameter and showing is only possible between two black are realized.In Fig. 8, three dotted lines are the crosstalk fringe inclination directions showing during the interval intermediate value of retrieval choosing cot parameter, and the dotted line of wherein label 3 is crosstalk fringe inclination direction during target cot parameter reference values.

When being started using dichotomizing search, the scope of search is very wide, between the interval corresponding cot parameter value for two black solid lines of retrieval, attempted at the intermediate value between the corresponding cot parameter value of two black solid lines first, select the dotted line corresponding cot parameter value of label 1, then the inclination angle of the dotted line of label 1 is calculated according to stereo-picture, than right side, the region of search of cot parameter, closer to vertical, is therefore updated to the corresponding cot parameter value of the black solid line in left side to the dotted line corresponding cot parameter value of label 1 to the dotted line of discovery label 1 by black solid line.Then choose the black solid line in left side to the intermediate value of the dotted line corresponding cot parameter value of label 1, the i.e. dotted line of label 2 corresponding cot parameter value, then the inclination angle of the dotted line of label 2 is calculated according to stereo-picture, than left side, the region of search of cot parameter, closer to vertical, is therefore updated to the dotted line corresponding cot parameter value of the dotted line corresponding cot parameter value of label 2 to label 1 to the dotted line of discovery label 2 by black solid line.Then choose the intermediate value of the dotted line corresponding cot parameter value of label 2 to the dotted line corresponding cot parameter value of label 1, the i.e. dotted line of label 3 corresponding cot parameter value, calculate through stereo-picture crosstalk stripe angle, the dotted line of discovery label 3 is vertical, then corresponding for the dotted line of label 3 cot parameter value is entered the array of (pitch, cot) as cot parameter reference values record.It can be seen that the quantity in region of search choosing value can be greatly reduced using two way classification, improve search efficiency.

Obtain (pitch, cot) after array, calculate the linear relationship of pitch and cot in array, refer to Fig. 9, it is the linear relationship schematic diagram of pixel correction parameter reference values and angle parameter reference value, each of which round dot is a logarithm value, abscissa is pitch, and vertical coordinate is cot, from figure it is also seen that, this array (pitch, cot) substantially meets the linear relationship of straight line.Therefore, there are following relations between pitch and cot, that is,：

Pitch=k*cot+b

Then calculate the value of k and b.Finally according to the value of k, b, the grating physical gate of light-splitting device away from parameter t, grating focal length parameter f1 of default light-splitting device and fixed position information (fixed position information refers to filming apparatus to the distance of stereoscopic display device), and combine the optical principle of three-dimensional imaging from array (pitch, cot optimal angle correct parameter reference values, and the angle correct parameter as stereoscopic display device are selected in).

Refer to Figure 10, it is the structure chart of another kind of parameter acquiring unit of the embodiment of the present invention.This parameter acquiring unit 34 includes：Screening obtains subelement 101 and analysis obtains subelement 102.

Screening obtains subelement 101 and meets the stereo-picture of set angle and corresponding angle correct parameter for the inclination angle obtaining crosstalk striped.

The stereo-picture that analysis acquisition subelement 102 is used for the inclination angle of crosstalk striped is met set angle scope carries out graphical analyses, obtains the stereo-picture comprising Breadth Maximum crosstalk striped, and obtains corresponding pixel correction parameter.It should be noted that, during the adjustment of the pixel-parameters at stereoscopic display device 22 end, on the stereo-picture of its display, the width of crosstalk striped can gradually change, width due to viewing area limits, if the crosstalk striped on stereo-picture has more than three, so during the width of the crosstalk striped in the middle of viewing area becomes big, crosstalk striped near viewing area edge can gradually be ejected viewing area, in other words, occur that the width of some crosstalk stripeds becomes big, the situation that the width of some crosstalk stripeds diminishes, until being only left two crosstalk stripeds in viewing area.When only comprising two crosstalk stripeds in viewing area, as long as the demarcation line of this two crosstalk stripeds is not at the midline position of viewing area, the area that so this remaining two crosstalk striped occupies viewing area still can change with the change of pixel-parameters, i.e. the width of a crosstalk striped can become big, and the width of an other crosstalk striped can diminish accordingly.And when the width of a crosstalk striped reaches maximum, representing that pixel-parameters now are optimal parameters, then analysis obtains subelement 102 and can record this stereo-picture, and obtains corresponding pixel-parameters.When calculating the width of crosstalk striped on stereo-picture, can be according to the analysis to color value on stereo-picture, determine the width of crosstalk striped according to distribution of color, or demarcation line can also be calculated to demarcation line or demarcation line to the distance of viewing area boundary line, and the width as crosstalk striped.Specifically, hypothesis pitch parameter is pixel-parameters, cot parameter is angle correct parameter reference values, from unlike the embodiment of Fig. 7, first cot parameter is adjusted, can cot parameter is carried out value using two way classification, calculate the inclination angle of crosstalk striped in the stereo-picture that stereoscopic display device shows, when crosstalk striped is vertical, selection cot parameter now is as optimal cot parameter.Then select cot parameter constant, again pitch parameter is adjusted, and the stereo-picture that stereoscopic display device shown carries out graphical analyses, when a crosstalk striped in stereo-picture is Breadth Maximum, obtain corresponding pitch parameter as optimal pitch parameter.At this moment the display effect of stereo-picture has two kinds of situations it is assumed that crosstalk striped is red an IOU issued by a post office stricture of vagina, then when the width of crosstalk striped is maximum, a kind of situation is that the red or green of pure color takes whole stereo-picture, and this represents the target having reached correction.And another kind situation is that only have the demarcation line of a crosstalk striped in stereo-picture, and red green pure color occupies marginal both sides respectively, this is accomplished by subsequently translational movement correction parameter (including coarse adjustment and fine setting) being adjusted again, and occupies the purpose of whole stereo-picture with the color reaching pure color.

The light-splitting device slant setting of stereoscopic display device is on display floater, the translational movement error that can be produced with the display unit arrangement cycle mismatch of display floater due to the spectrophotometric unit of light-splitting device, described translational movement correction parameter is exactly to correct this translational movement error, if be not corrected for, stereo-picture can be made to produce picture crosstalk problem.

Furthermore, if stereoscopic display device is located at a certain fixed position and in the case that angle correct parameter has obtained, stereoscopic display device is according to the angle correct parameter display stereo-picture obtaining, a plurality of crosstalk striped now be may possibly still be present on stereo-picture, its reason is because the width of crosstalk striped is less than viewing area, although so that crosstalk striped is in vertical state, yet suffering from the crosstalk striped of more than three in viewing area.

For this situation, the scheme that the application adopts is：Carry out translational movement coarse adjustment first, the central point of crosstalk striped is adjusted to the center of viewing area, the width then increasing crosstalk striped again, until the width more than or equal to viewing area, is finally finely adjusted, make the pure color of setting occupy whole viewing area.Accordingly, it would be desirable to obtain the thick correction parameter of translational movement of the corresponding stereo-picture in described inclination angle when described stereoscopic display device is located at each fixed position respectively.

Refer to Figure 33, it is a kind of structure chart of parameter acquiring unit of the embodiment of the present invention.This parameter acquiring unit 34 includes central point detection sub-unit 311 and thick translation parameterss obtain subelement 312.Central point detection sub-unit 311 is used for judging whether the central point of crosstalk striped on stereo-picture is in the central area of described screen area.Thick translation parameterss obtain subelement 312 and are used for, when the central spot of crosstalk striped is in the central area of described screen area, obtaining corresponding translational movement parameter as the thick correction parameter of described translational movement.If the central point of crosstalk striped is not on the central area of described screen area, adjust the translational movement parameter of described stereo-picture, so that described stereoscopic display device shows described stereo-picture according to the translational movement parameter after adjustment；Then repeat and judge whether the central point of described crosstalk striped is in described stereo-picture screen area.

Specifically, described central area refers to certain abscissa scope in screen area, and the such as abscissa of screen area center line is 5, then this region can be (4,6).In default interval, adjustment translational movement parameter, it is possible to utilize image analysis technology, is analyzed to the stereo-picture that stereoscopic display device shows.If at least three crosstalk stripeds are had on stereo-picture, then detect whether the central point of corresponding crosstalk striped is in the central area of on-screen display (osd) area, for example this stereo-picture is left view, pure green image should be shown under preferable dispaly state, then find out the central point of all green crosstalk stripeds on this stereo-picture, and detect whether the central spot of some green crosstalk striped in the central area of screen area.If there are a green crosstalk striped central spot in the central area of screen area, then using translational movement parameter now as the thick correction parameter of translational movement.If two crosstalk stripeds are substantially had on stereo-picture, illustrate that the central point of now crosstalk striped necessarily deviates the central area of screen area, by adjusting translational movement parameter, crosstalk striped is made gradually to translate, until the central spot of a crosstalk striped is in the central area of screen area, and record translational movement parameter now is the thick correction parameter of translational movement；Or until the color of a crosstalk striped is full of whole screen area, then illustrate now to have reached correction purpose, record translational movement parameter now is the thick correction parameter of translational movement, and the thick correction parameter of this translational movement is also optimal translational movement correction parameter.

Obtain the thick correction parameter of corresponding translational movement in multiple fixed positions, pixel-parameters can be adjusted on this basis, make crosstalk striped cover whole screen area, thus calculating the grating pixel correction parameter obtaining light-splitting device and grating focus correction parameter.The purpose obtaining the thick correction parameter of translational movement is to quickly make crosstalk striped cover whole screen area, thus calculating grating pixel correction parameter and the grating focus correction parameter of light-splitting device.

Calculate the grating pixel correction parameter of light-splitting device and the grating focus correction parameter of stereoscopic display device, its objective is grating pixel correction parameter and grating focus correction parameter are compared with preset value, prevent that the grating pitch leading to and grating focal length are misfitted with preset value because of assembly technology error, and affect the problem of display effect.Therefore, the embodiment of the present invention can also obtain grating focus correction parameter f.The embodiment of the present invention can also obtain grating pixel correction parameter t0 simultaneously.In implementing, when crosstalk striped width cover described screen area when it is believed that now corresponding grating focal length parameter and grating pixel-parameters be optimal, can be used as the grating pixel correction parameter of stereoscopic display device and grating focus correction parameter.When the central point of crosstalk striped on stereo-picture is located at the central area of screen area, can determine whether whether the width of this crosstalk striped covers described screen area, if the width of crosstalk striped is not covered with described screen area, the width of crosstalk striped then can be increased by adjusting pixel-parameters, until the width cover screen region of crosstalk striped.

Refer to Figure 32, it is a kind of structure chart of parameter acquiring unit of the embodiment of the present invention, this parameter acquiring unit 34 includes width of fringe detection sub-unit 321 and pixel focal length parameter acquiring subelement 322.Width of fringe detection sub-unit 321 is used for judging whether the width of described crosstalk striped covers described screen area.Pixel focal length parameter acquiring subelement 322 is used for when the width of crosstalk striped covers described screen area, using the pixel-parameters corresponding grating pixel-parameters of the stereo-picture obtaining as described grating pixel correction parameter, using corresponding for the pixel-parameters of stereo-picture grating focal length parameter as described grating focus correction parameter.

Specifically, by adjusting pixel-parameters in default interval, the width of crosstalk striped in the stereo-picture that stereoscopic display device shows is made constantly to change, when the width of crosstalk striped is more than or equal to the width of screen area, i.e. crosstalk striped covers screen area, calculate this pixel-parameters corresponding grating pixel-parameters, grating focal length parameter, using as grating pixel correction parameter, grating focus correction parameter.

Can be according to below equation when calculating grating pixel correction parameter and grating focus correction parameter：

Wherein, d_iBe located at fixed position information during the i-th fixed position for described stereoscopic display device, that is, stereoscopic display device be located at during the i-th fixed position with the distance between filming apparatus information.pitch_iFor described stereoscopic display device be located at the i-th fixed position when and described crosstalk striped cover described screen area when described stereo-picture pixel-parameters, f is the grating focus correction parameter of the light-splitting device of stereoscopic display device, and t0 is the grating pixel correction parameter of the light-splitting device of stereoscopic display device.

Further, when getting stereoscopic display device and being located at multiple fixed position during the pixel correction parameter of corresponding stereo-picture, when the described grating pixel correction parameter calculating described light-splitting device and grating focus correction parameter, the fixed position information residing for the pixel correction parameter corresponding to stereo-picture during multiple fixed position and described stereoscopic display device that specifically can be located at the described stereoscopic display device of described acquisition all substitutes into formula：Form matrix, and calculate the minimum error of described matrix, corresponding grating pixel pitch parameter and grating focal length parameter will be met during minimum error to the grating pixel correction parameter that should be used as described light-splitting device and grating focus correction parameter.

Further, during adjustment pixel-parameters, change linear relationship parabolically shape between pixel-parameters and crosstalk width of fringe, therefore crosstalk width of fringe just cover screen region when, pixel focal length parameter acquiring subelement 322 can obtain two pixel-parameters values, i.e. the first pixel-parameters and the second pixel-parameters.In theory when being adjusted to the meansigma methodss of the first pixel-parameters and the second pixel-parameters, the width of crosstalk striped reaches maximum, therefore pixel focal length parameter acquiring subelement 322 can calculate described first pixel-parameters and the meansigma methodss of described second pixel-parameters, using the described meansigma methodss calculating as described crosstalk striped width cover described screen area when described stereo-picture pixel-parameters.

The application is corrected to stereoscopic display device in many fixed positions, and obtains correction parameter using the inclination angle of crosstalk striped, and the accuracy of calculated correction parameter is high, and can greatly improve correction efficiency.

After obtaining grating pixel correction parameter and grating focus correction parameter, for the accuracy eliminating calculation error further and improve correction further, again translational movement can be finely adjusted in the case that described stereoscopic display device is opened and followed the tracks of, that is, obtain translational movement fine setting parameter.

Refer 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 includes：Micro- translation parameterss obtain subelement 111.Micro- translation parameterss obtain subelement 111 in the case that the inclination angle of the crosstalk striped that described Dip countion unit calculates meets predetermined angle scope and described stereoscopic display device opens tracking, and the picture crosstalk scoring according to calculating obtains the translational movement fine setting parameter of corresponding stereo-picture.The interval that translational movement finely tunes parameter can be with the thick correction parameter of translational movement of acquisition as intermediate value, and left and right respectively sets a scope to determine.Described picture crosstalk scoring refers to the evaluation criteria to three-dimensional picture crosstalk situation.Acquisition methods that translational movement finely tune parameter are described below.It should be noted that the method for adjustment of the thick correction parameter of translational movement is similar with the method for adjustment that translational movement finely tunes parameter, here is not described in detail.

Specifically, adjustment translational movement typically has corrected that in angle correct parameter, grating pixel correction parameter, grating focus correction parameter and carries out in the case of completing, assume that xoffadd parameter is translational movement fine setting parameter, crosstalk striped is red an IOU issued by a post office stricture of vagina, by suitably adjusting xoffadd parameter, red an IOU issued by a post office stricture of vagina is made to translate in the horizontal direction, when moving to a suitable numerical value, the image that left and right photographic head grabs assumes redness the most bright-coloured and green respectively.This suitable parameter is exactly optimal xoffadd parameter.

When stereoscopic display device adopts optimal xoffadd parameter display stereo-picture, the stereo-picture that left and right two photographic head photographs is the red and green image of pure color respectively, and red and green respectively filled with whole image region, no hang angle, so beholder, when observing stereo-picture, can experience optimal 3D effect.

The trimming process of xoffadd parameter is directly to traverse maximum from the minima of the xoffadd parameter of detection interval, then therefrom selects the best xoffadd parameter of a spectrophotometric result.Speed in order to accelerate to search for can be adjusted with a variable step-length.

For example, from the beginning of initial translational movement xoffadd=0, increase a numerical value every time, then stereoscopic display device is configured.After every time equipment being configured, capture stereo-picture by filming apparatus immediately, then image analysis technology is utilized to analyze the color of stereo-picture, and according to color change situation, step-length is adjusted, here a crosstalk scoring can be set according to the color value of pixel on stereo-picture, according to crosstalk scoring situation, the change step of xoffadd parameter is adjusted.The crosstalk scoring of such as stereo-picture is very low, illustrates far apart from optimal xoffadd parameter value, so needing to increase the larger numerical value of ratio, to accelerate search speed.Whereas if the crosstalk scoring of stereo-picture is higher, illustrate close to optimal xoffadd parameter value, so the smaller xoffadd parameter value of one step-length of setting, with precise search.After the crosstalk scoring of image reaches certain threshold value, xoffadd parameter now can be saved in an array, from this array, finally find out an optimal xoffadd parameter.

Because there are left view and two images of right view in the stereo-picture that stereoscopic display device provides, refer to Figure 12, Figure 12 is the schematic diagram of the optimal viewing location of stereo-picture, according to optical imaging concept, only when the left photographic head of filming apparatus and right photographic head are individually positioned in optimal viewing point, i.e. circled positions in Figure 12, stereo-picture the most bright-coloured just can be seen, so according to filming apparatus apart from stereoscopic display device distance difference, selecting optimum from multiple candidate's xoffadd parameter values can have two schemes：

The first, when two photographic head of filming apparatus are located at optimum position, translational movement computation subunit 111 obtains picture crosstalk and scores translational movement parameter corresponding to highest stereo-picture as optimal translational movement fine setting parameter.In this case, when the image that left side photographic head is captured is the most bright-coloured, the image on the right should also be the most bright-coloured, so left and right stereo-picture is to reach the most bright-coloured degree simultaneously.Optimal xoffadd parameter now exactly can make the left side (or the right) image xoffadd parameter value the most bright-coloured.Now only need to be according to the image of a photographic head collection it may determine that going out optimal xoffadd parameter.

Second, when two photographic head of filming apparatus are not located at optimum position, specifically, when two photographic head are not all placed on optimal optics viewing location, two photographic head, all before optimum position, or two photographic head are all placed on after optimal viewing location, refer to Figure 13 and Figure 14, Figure 13 is placed on the schematic diagram after optimal viewing location for photographic head, and Figure 14 is placed on the schematic diagram before optimal viewing location for photographic head.At this moment it is possible that：Left side photographic head has grabbed solid-color image the most bright-coloured, but the image that the right photographic head is captured but is not solid-color image the most bright-coloured, or just contrary, right image has detected that solid-color image the most bright-coloured, and the left side is also not detected by solid-color image the most bright-coloured.In this case, translational movement computation subunit 111 constitutes a selection region according to the xoffadd parameter being saved in array, and obtains the intermediate value of this selection region as optimal xoffadd parameter.And choose optimal xoffadd parameter from selection region and can adopt different schemes, the present embodiment provides three kinds of preferred versions：

(1) if corresponding xoffadd parameter differs very little when the image that left and right photographic head grabs reaches the most bright-coloured, as shown in figure 15, Figure 15 is a kind of curve synoptic diagram of the translational movement fine setting parameter array of selection, in Figure 15, abscissa is xoffadd parameter value, vertical coordinate is crosstalk score value, article two, curve is left view and the curve of right view corresponding xoffadd parameter array respectively, at this moment the right and left image can be taken respectively to reach the meansigma methodss of xoffadd parameter during the most bright-coloured degree (i.e. vertical coordinate is maximum) as optimal xoffadd parameter, the xoffadd parameter taking dotted line position in Figure 15 is as optimal xoffadd parameter.

(2) if corresponding xoffadd parameter difference is larger when the image that left and right photographic head grabs reaches the most bright-coloured, as shown in figure 16, in Figure 16, abscissa is xoffadd parameter value, vertical coordinate is crosstalk score value, less two curves of peak value are left view and the curve of right view corresponding xoffadd parameter array respectively, at this moment the xoffadd parameter corresponding to the maximum of the sum of the ordinate value of xoffadd parameter curve taking left view and right view is optimal xoffadd parameter, will two curve vertical coordinates be added, form a higher curve of peak value in Figure 16, then the corresponding abscissa of maximum taking this curve vertical coordinate is chosen to be optimal xoffadd parameter.

(3) refer to Figure 17, Figure 17 is the curve synoptic diagram that the translational movement that another is chosen finely tunes parameter array, in Figure 17, abscissa is xoffadd parameter value, and vertical coordinate is crosstalk score value, and two curves are left view and the curve of right view corresponding xoffadd parameter array respectively.Set a vertical coordinate threshold value (as shown in threshold line in Figure 17), filter out four abscissas (i.e. tetra- abscissas of A, B, C, D), the intermediate value then taking abscissa B, C or take abscissa A, D intermediate value as optimum xoffadd parameter.

The application is corrected to stereoscopic display device in many fixed positions, and obtain correction parameter using the inclination angle of crosstalk striped, the accuracy of calculated correction parameter is high, during using this correction parameter to correct stereoscopic display device, the impact causing because of rigging error, the display effect of lifting stereoscopic display device can be eliminated.

Refer to Figure 18, it is the structure chart of the correction parameter acquisition device of another kind of stereoscopic display device of the embodiment of the present invention.Compared with the embodiment of Fig. 3, the correction parameter acquisition device 21 of the stereoscopic display device shown in Figure 18, except including image acquisition unit 31, crosstalk fringe detection unit 32, Dip countion unit 33, parameter acquiring unit 34, also includes：Image analyzing unit 181.

Further, refer to Figure 19, it is a kind of structure chart of image analyzing unit of the embodiment of the present invention.This image analyzing unit further includes：Crosstalk score calculation subelement 191.Crosstalk score calculation subelement 191 is used for the color according to described stereo-picture, calculates picture crosstalk scoring.Described crosstalk score calculation subelement 191 can be by carrying out subregion statistics to the color value of described stereo-picture, color value further according to zones of different is interval, give corresponding weights to zones of different, then the color value in all regions is sued for peace and weighted sum, finally using all weighted color value and with all colours value and ratio as picture crosstalk score.

Specifically, it is required for the cross talk conditions of stereo-picture are detected at many in this application, such as translational movement computation subunit 111 is accomplished by picture crosstalk and scores to judge whether stereo-picture is solid-color image, described picture crosstalk scoring is an evaluation criterion to three-dimensional picture crosstalk degree, if the region that solid color occupies stereo-picture is more, and color is more bright-coloured, then the picture crosstalk scoring of this stereo-picture is higher.

Taking redness as a example, judge red pixel bright-coloured degree when, 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, can be concluded that image belongs to very bright-coloured redness.Can determine the bright-coloured degree of the entirety of image according to such method.Specifically, when needing to pass judgment on red image, the color value of pixel on image can be done with a subregion weighted sum, the color value weighted sum of all pixels point divided by unweighted numerical value and, by the use of this numerical value as to stereo-picture crosstalk evaluation.The weighting of so-called subregion, refer to give bigger weight closer to the color value of hunting pink (hunting pink color value is 0), such as then it is multiplied by a larger weight 64 in the interval numerical value summation of color value (0-5), a weight 16 is multiplied by the interval numerical value summation of color value (5-10), the interval numerical value of color value (10-15) and be multiplied by a little weight 4, the interval numerical value summation of color value (15-20) keeps constant, by weighted sum divided by numerical value unweighted and that one 1 to 64 can be obtained, of this numerical value, image can be made with the evaluation of a degree of crosstalk.Another method similarly is, it is red stereo display region for target, in addition to above-mentioned weighted sum is carried out to red objects value, can also be to other non-targeted color value in this stereo display region, green color value as crosstalk, these non-targeted color intervals are sued for peace and is multiplied by the weight of a negative, then interval for all colours value in this stereo display region and its corresponding weighted value is multiplied and sues for peace, sum divided by unweighted all colours interval value, one can be obtained with this and be in (- 64, 64) value between, of this numerical value, image can also be made with the evaluation of a degree of crosstalk.Green stereo-picture is also processed in this way, a judgement to green bright-coloured degree can be obtained.

Refer to Figure 21, it is the structure chart of the correction parameter acquisition device of another stereoscopic display device of the embodiment of the present invention, compared with the embodiment of Figure 18, the correction parameter acquisition device 21 of the stereoscopic display device shown in Figure 21, except including image acquisition unit 31, crosstalk fringe detection unit 32, computing unit 33, parameter acquiring unit 34, image analyzing unit 181, screen area detector unit 182, also includes：Detection interval arranging unit 211.

Detection interval arranging unit 211 is used for arrange parameter detection interval, and the detection interval of setting is sent to stereoscopic display device, so that stereoscopic display device is according to the detection interval display stereo-picture of setting, in order to the calculating of correction parameter.The detection interval of setting can include interval size, parameter adjustment step-length etc..And in trimming process, angle correct parameter, grating pixel correction parameter, translational movement coarse adjustment parameter, translational movement fine setting correction parameter etc. are required for reference value detection interval is configured.For example when correcting translational movement, first pass through detection interval arranging unit 211 and the detection interval of translational movement correction parameter and the step-length of value in detection interval are set, and the detection interval of setting is sent to micro- translation parameterss acquisition subelement 111, then micro- translation parameterss obtain subelement 111 (include translational movement and finely tune parameter and the thick correction parameter of translational movement) and, according to the stereo-picture parameter reference values corresponding with detection interval receiving, obtain optimal translational movement correction parameter.
