In the embodiment of the present invention, the inclination angle of crosstalk striped refers to：Crosstalk striped and the folder of horizontal direction Angle, or the angle of crosstalk striped and vertical direction.When the inclination angle of crosstalk striped is crosstalk striped and water Square to angle when, the predetermined angle of crosstalk striped may range from [- 90 °, -70 °] or [70 °, 90 °], if now the inclination angle of crosstalk striped fall into above-mentioned interval then it is assumed that stereoscopic display device The stereo-picture crosstalk striped of display is in vertically, obtains the corresponding solid in inclination angle of this crosstalk striped simultaneously The correction parameter of image.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 going here and there Disturb striped inclination angle fall into above-mentioned interval then it is assumed that on stereo-picture that now stereoscopic display device shows Crosstalk striped is in vertically, obtains the correction parameter of the corresponding stereo-picture in inclination angle of this crosstalk striped simultaneously.
Refer to Fig. 3, it is the structure of the correction parameter acquisition device of Fig. 2 Stereo display equipment Figure.This device includes image acquisition unit 31, crosstalk fringe detection unit 32, Dip countion list 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 are repeatedly adjusted Whole, to find out optimal parameter.And filming apparatus 23 can be in real time to inclusion stereoscopic display device 22 The image frame of display screen is tracked shooting, and the image frame photographing is sent to figure As acquiring unit 31.
Image acquisition unit 31 obtains stereoscopic display device 22 from the image frame receiving and shows The stereo-picture showing, with the change of image when obtaining parameter adjustment each time, and will get Stereo-picture sends crosstalk fringe detection unit 32 to.
Because the image frame that filming apparatus 23 obtain not only includes the axonometric chart that stereoscopic display device shows Picture, also includes the external environment condition beyond viewing area, for avoiding external environment influence correction parameter Accuracy, needs image acquisition unit 31 before obtaining stereo-picture, need to determine image frame first The viewing area of Stereo display equipment 22, 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 described stereoscopic display device of inclusion 22 that filming apparatus 23 photograph The image frame of display screen；Determination subelement is used for determining that the image that receiving subelement receives is drawn The screen area of face Stereo display equipment 22, and obtain the axonometric chart that described screen area shows Picture.Determination subelement can extract the image channel value in viewing area using image analysis technology, so Afterwards 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 analyzes 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 according to default luminance threshold, brightness of image being analyzed The stereo-picture that subelement 204 obtains carries out binary conversion treatment, to obtain corresponding quasi- screen area Domain.The binaryzation of so-called image it is simply that the gray value of the pixel on image is set to 0 or 255, Namely whole image is presented significantly only black and white visual effect, such that it is able to substantially On tell screen area.
Range searching subelement 202 is used for searching on the quasi- screen area after binary conversion treatment The region of rope preset 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 draws for the region of the preset shape searching is carried out merger Point, to determine the screen area of stereoscopic display device described in described image picture.Range searching The quantity of the setting regions that subelement 202 searches out might have a lot, and these setting regions can Can vary, 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, i.e. certain area coincidence Number of times more at most gives a higher weight.Divide process refer to according to merger after region power Redistribution, removes the region that weight is less than certain value, and again marks off the region setting shape, make For screen area.
Elementary area crosstalk fringe detection unit 32 is used for detecting the crosstalk in described stereo-picture Striped.Crosstalk fringe detection unit 32 can be by calculating the color of pixel in stereo-picture Value, to obtain the crosstalk striped in stereo-picture.For example, it is possible to pass through stereoscopic image conversion To HSV space, obtain the value on color component, HSV space is to embody color intuitive nature A kind of color space, also referred to as hexagonal pyramid model (Hexcone Model), divide in this color space There are not three color parameters：Tone (Hue), saturation (Saturation) and brightness (Value). For red green crosstalk striped, region between 0 to 20 for the color value is red, color value Region between 40 to 60 is green.Crosstalk fringe detection unit 32, thus can know Distribution of color on road stereo-picture, whether there is crosstalk striped thus detecting on stereo-picture. In conjunction with referring to Fig. 4, it is a stereo-picture to be corrected, and wherein black region represents red, White space represents green, and as can be seen from Figure 4 this stereo-picture has three red six strings of Three Greens Disturb striped.
Dip countion unit 33 is used for calculating the inclination angle of the described crosstalk striped detecting.From Fig. 4 In can see, crosstalk striped is often tilt, and whole trimming process, if with continuous Image come if embodying it is simply that first making the center of crosstalk striped and the center superposition of viewing area, Then the width making crosstalk striped in image becomes larger to reduce the quantity of crosstalk striped, until Till single tone occupies viewing area.And the spectrophotometric result in order to reach, and prevent from standing Extension angle is occurred on body image (hang angle and refer to that on stereo-picture, certain region does not have display pattern, example As a pure red rectangle stereo-picture, one angle does not show red pattern), this enforcement Example calculates 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 in crosstalk striped water Correction parameter is calculated, the application is not limited thereto in the case of flat.
Further, Dip countion unit 33 can pass through to obtain the demarcation line between crosstalk striped, And 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 include that demarcation line obtains subelement 51 and computation subunit 52.It is single that demarcation line obtains son Unit 51 is used for determining the boundary between crosstalk striped according to the color value of pixel in stereo-picture Line.Computation subunit 52 is used for dividing according to calculate described demarcation line acquisition subelement and determine The inclination angle in boundary line, using the inclination angle as described crosstalk striped.Red green crosstalk for example shown in Fig. 4 The stereo-picture of striped, region between 0 to 20 for the color value is red, and color value is 40 Region between 60 is green, then in image, color value is not belonging to this two interval pixels Point may be considered the pixel on demarcation line between crosstalk striped.Obtain on demarcation line After pixel, Dip countion unit 33 can be by the side such as method of least square or M algorithm for estimating Method simulates this demarcation line, 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 vertical A plurality of marginal inclination angle in body image, and calculate 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 divide Do not obtain this five marginal inclination angles, then calculate the meansigma methodss at this five marginal inclination angles, Thus also making result of calculation more accurate.
Further, Dip countion unit 33 calculates during demarcation line is to fit to line using pixel Bar, 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 using method matching outlets such as method of least square Then calculating inclination angle again will obtain a wrong numerical value to bar.Therefore calculate marginal inclination angle it Before can detect marginal wire distribution between described crosstalk striped first with statistic algorithm.Please Referring to Fig. 6, it is the structure chart of another kind of Dip countion unit of the embodiment of the present invention.With Fig. 5 Compare, the Dip countion unit 33 shown in Fig. 6 obtains subelement 51 except including demarcation line With computation subunit 52, also include wire detection sub-unit 61.Wire detection sub-unit 61 is used After obtaining described demarcation line in described demarcation line acquisition subelement 51, using statistic algorithm inspection Survey the marginal wire distribution between described crosstalk striped.If wire detection sub-unit 61 is examined Measuring demarcation line is straight line, then calculate marginal inclination angle by Dip countion unit 33 again.If Detect that demarcation line is not straight line, then 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 be judged by calculating the covariance matrix of this coordinate sequence Its linear distribution.And calculate covariance matrix and will first data be carried out with decentration, so point sequence Average (vectorial) is：
So covariance matrix is：
Then wire detection sub-unit 61 can calculate eigenvalue E0 and E1 of covariance matrix, now Feature Distribution value represent the maximum and of the distribution that these pixels can reach on some direction Little variance, it is possible to ratio E0/E1 by comparing eigenvalue of maximum and minimal eigenvalue, to judge The linear degree of curve.A threshold value (this threshold value preferred value 7) can be set, work as eigenvalue of maximum Be more than during this threshold value with the ratio E0/E1 of minimal eigenvalue it is possible to think this demarcation line be one straight Line, is otherwise then 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 parameter value corresponding to current stereo-picture, optimal for calculating Correction parameter.The vertical condition of crosstalk striped described here is that calculating correction parameter is the most accurate Situation, and in actual applications, can as needed satisfaction needed for crosstalk stripe angle be set Determine angle and make specific range set, the level inclination of such as crosstalk striped meets 80 degree～100 It is also possible to think that the inclination angle of crosstalk striped meets default angular range between degree, here not with Be limited.The correction parameter of stereoscopic display device 22 includes angle correct parameter, the thick school of translational movement Positive parameter, grating pixel correction parameter, translational movement fine setting parameter etc..
Due to the light-splitting device of stereoscopic display device be slant setting on display floater, light-splitting device On spectrophotometric unit arrange along a direction, the display unit on display floater is along another direction Arrangement, the angle in this both direction is the error easily producing during assembling, if not in addition school Positive-angle error, then can produce image and tilt, hang the impact display effect such as angle, crosstalk, granular sensation Situation, even and if angle correct parameter is used for correcting this error.
The calculation of correction parameter can determine according to actual needs.For angle correct ginseng Number and pixel correction parameter, the application provides two kinds of calculations.
Refer to Fig. 7, it is a kind of structure chart of parameter acquiring unit of the embodiment of the present invention.This ginseng Number acquiring unit 34 includes：Reference value obtains subelement 71, linear relationship computation subunit 72 With angle pixel computation subunit 73.
Reference value obtains subelement 71 and is used for meeting predetermined angle scope when institute according to described inclination angle State multiple pixel-parameters corresponding to multiple stereo-pictures, obtain corresponding with the plurality of pixel-parameters Angle correct parameter reference values.Pixel-parameters described here are set in advance, and deposit In stereoscopic display device, stereoscopic display device shows stereo-picture according to different pixel-parameters. And when stereoscopic display device shows stereo-picture according to each pixel-parameters, all can be to angle Parameter is finely adjusted, so according to display stereo-picture analysis it is possible to find out with often One pixel-parameters is corresponding, and crosstalk stripe angle meets the angle correct of predetermined angle scope Parameter reference values, thus can be formed by of pixel-parameters and angle correct parameter reference values Array.
Linear relationship computation subunit 72 is used for according to described pixel-parameters and angle correct parameter The array of reference value, calculates the linear relationship of described pixel-parameters and angle correct parameter reference values.
Angle pixel computation subunit 73 is used for according to described pixel-parameters and angle correct parameter The linear relationship of reference value, determines best angle correction parameter reference value, using as described inclination angle The angle correct parameter of corresponding stereo-picture.
As an example it is assumed that pitch parameter is pixel-parameters, cot parameter is angle correct parameter reference Value, sets pitch parameter reference values first, makes stereoscopic display device according to this pitch default Parameter reference values show stereo-picture, then adjust the value of cot parameter, make the crosstalk bar on stereo-picture Stricture of vagina angle is changed, and calculates the inclination angle of crosstalk striped in real time.It is vertical when calculating crosstalk striped During state (or inclination angle meets default angular range), then record pitch parameter reference values now With cot parameter reference values.Then according to default detection interval resets another pitch parameter reference Value, and vertical to the crosstalk striped of stereo-picture by adjusting the value of cot parameter, and record pitch again Parameter reference values and cot parameter reference values.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 adds Fast search speed.Refer to Fig. 8, it is the schematic diagram using dichotomizing search pixel correction parameter. Wherein solid black lines are the crosstalk stripeds that during two ends in retrieval interval taking cot parameter, stereo-picture shows Inclination angle, that is, pitch parameter reference values select in the case of, according to the display surface of stereoscopic display device Plate and the physical characteristics of light-splitting device, on the stereo-picture adjusting cot parameter and showing, crosstalk striped inclines Changes in pitch is only possible between two black are realized.In Fig. 8, three dotted lines are the inspections choosing cot parameter The crosstalk fringe inclination direction showing during the intermediate value of rope interval, the dotted line of wherein label 3 is target cot Crosstalk fringe inclination direction during parameter reference values.
When being started using dichotomizing search, the scope of search is very wide, and retrieval is interval to be two black solid lines pair Between the cot parameter value answered, first at the intermediate value between the corresponding cot parameter value of two black solid lines Attempted, that is, selected the dotted line corresponding cot parameter value of label 1, then calculated according to stereo-picture The inclination angle of the dotted line of label 1, find the dotted line of label 1 than right side black solid line closer to 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 the dotted line of label 1 Corresponding cot parameter value.Then choose the black solid line in left side to the dotted line corresponding cot parameter value of label 1 Intermediate value, i.e. the dotted line of label 2 corresponding cot parameter value, then according to stereo-picture calculate label The inclination angle of 2 dotted line, find label 2 dotted line than left side black solid line closer to vertical, therefore by cot The dotted line that the region of search of parameter is updated to dotted line corresponding cot parameter value to the label 1 of label 2 corresponds to Cot parameter value.Then choose the dotted line pair of the dotted line corresponding cot parameter value of label 2 to label 1 The intermediate value of the cot parameter value answered, i.e. the dotted line of label 3 corresponding cot parameter value, through axonometric chart As crosstalk stripe angle calculates, find that the dotted line of label 3 is vertical, then the dotted line of label 3 is corresponded to Cot parameter value enter the array of (pitch, cot) as cot parameter reference values record.It can be seen that adopting two Point-score can greatly reduce the quantity in region of search choosing value, improves search efficiency.
After obtaining (pitch, cot) array, calculate the linear relationship of pitch and cot in array, please join See Fig. 9, it is shown with the linear relationship of angle correct parameter reference values for pixel correction parameter reference values It is intended to, each of which round dot is a logarithm value, and abscissa is pitch, and vertical coordinate is cot, from figure It can also be seen that this array (pitch, cot) substantially meets the linear relationship of straight line.Therefore, pitch There are following relations and cot between, that is,：
Pitch=k*cot+b
Then calculate the value of k and b.Finally according to the grating physical gate of the value of k, b, light-splitting device Away from parameter t, grating focal length parameter f 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 three-dimensional imaging optical principle from Optimal angle correct parameter reference values are selected, to set as stereo display in array (pitch, cot) Standby angle correct parameter.
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 set angle scope for the inclination angle obtaining crosstalk striped Stereo-picture and corresponding angle correct parameter.
Analysis obtains subelement 102 and is used for meeting set angle scope to the inclination angle of crosstalk striped Stereo-picture carries out graphical analyses, obtains the maximum stereo-picture of setpoint color accounting, and obtains Corresponding pixel-parameters.
Specifically it is assumed that pitch parameter is pixel-parameters, cot parameter is angle correct parameter reference Value, from unlike the embodiment of Fig. 7, is adjusted to cot parameter first, can adopt two Point-score cot parameter is carried out value, calculates crosstalk striped in the stereo-picture that stereoscopic display device shows Inclination angle, when crosstalk striped vertically (or inclination angle meets default angular range), choose now Cot parameter as optimal cot parameter.Then select cot parameter constant, then pitch parameter is carried out Adjustment, and the stereo-picture that stereoscopic display device is shown carries out graphical analyses, obtains setpoint color and accounts for The maximum stereo-picture of ratio, and obtain corresponding pitch parameter as optimal pitch parameter.Here The described maximum stereo-picture of setpoint color accounting that obtains refers in pitch parameter tuning process, The width of crosstalk striped can gradually change, and when the width of crosstalk striped is maximum, chooses pitch now Parameter is as optimal pitch parameter.At this moment the optimal display result of stereo-picture have 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 the red of pure color Or green take whole stereo-picture, this represent reached correction target.And another kind situation is Only have the demarcation line of a crosstalk striped in stereo-picture, and red green pure color occupies marginal two respectively Side, this is accomplished by subsequently translational movement correction parameter being adjusted again, and is occupied with the color reaching pure color The purpose of whole stereo-picture.
The light-splitting device slant setting of stereoscopic display device on display floater, due to light-splitting device point The translational movement error that the display unit arrangement cycle mismatch of light unit and display floater can produce, described Translational movement correction parameter (include the thick correction parameter of translational movement and translational movement fine setting parameter) be exactly in order to Correct this translational movement error, if not being corrected for, stereo-picture can be made to produce picture crosstalk and ask Topic.
Furthermore, it is understood that in the case that angle correct parameter has obtained, stereoscopic display device according to The angle correct parameter display stereo-picture obtaining, now may possibly still be present a plurality of on stereo-picture Crosstalk striped, its reason is because the width of crosstalk striped is less than viewing area, although so that crosstalk Striped is in vertical state, but yet suffers from the crosstalk striped of more than three in viewing area.
For this situation, the scheme that the application adopts is：Carry out coarse adjustment first, by crosstalk striped Central point is adjusted to the center of viewing area, then increases the width of crosstalk striped again until being more than Or the width equal to viewing area, finally it is finely adjusted, make the pure color of setting occupy whole viewing area.
Refer to Figure 30, 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 that the central point of crosstalk striped on stereo-picture is The no central area being in described screen area.Thick translation parameterss obtain subelement 312 and are used for working as The central spot of crosstalk striped, when the central area of described screen area, obtains corresponding translation Amount parameter is as the thick correction parameter of described translational movement.
Specifically, described central area refers to certain abscissa scope in screen area, The abscissa of such as screen area center line is 5, then this region can be (4,6).Pre- If interval in adjustment translational movement parameter it is possible to utilize image analysis technology, to stereo display The stereo-picture that equipment shows is analyzed.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, should show pure green image, then look under preferable dispaly state Go out the central point of all green crosstalk stripeds on this stereo-picture, and detected whether that some is green The central spot of color crosstalk striped is in the central area of screen area.If there are a green crosstalk The central spot of striped 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 now The central point of crosstalk striped necessarily deviates the central area of screen area, is translated by adjustment Amount parameter, makes crosstalk striped gradually translate, until the central spot of a crosstalk striped is in screen The central area in region, 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 To correction purpose, record translational movement parameter now is 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 sentence Whether the width of this crosstalk striped disconnected covers described screen area, if the width of crosstalk striped does not have Cover described screen area, then can increase the width of crosstalk striped by adjusting pixel-parameters, Until the width cover screen region of crosstalk striped.
Refer to Figure 31, 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 grating pixel parameter acquiring Unit 322.Width of fringe detection sub-unit 321 is used for judging that the width of described crosstalk striped is The described screen area of no covering.Grating pixel parameter acquiring subelement 322 is used for when crosstalk striped Width cover described screen area when, by described crosstalk striped cover described screen area when institute The pixel-parameters corresponding grating pixel-parameters stating stereo-picture are as grating pixel correction parameter.
Specifically, by adjusting pixel-parameters in default interval, stereoscopic display device is made to show Stereo-picture in the width of crosstalk striped constantly change, when the width of crosstalk striped is more than or waits When the width of screen area, that is, crosstalk striped covers screen area, calculates this pixel-parameters and corresponds to Grating pixel-parameters, and as grating pixel correction parameter.Calculate grating pixel correction Can be according to below equation during parameter：
D/ (d+f)=t0/pitch,
Wherein, d is the fixed position information of described stereoscopic display device, and that is, filming apparatus are to vertical The distance between body display device information, pitch is that the width of described crosstalk striped covers described screen The pixel-parameters of described stereo-picture during curtain region, f is dividing of default described stereoscopic display device The grating focal length parameter of optical device, t0 is the grating image of the light-splitting device of described stereoscopic display device Plain parameter, and as grating pixel correction parameter.
Further, during adjustment pixel-parameters, pixel-parameters and crosstalk width of fringe it Between change linear relationship parabolically shape, therefore crosstalk width of fringe just cover screen area During domain, grid pixel-parameters obtain subelement and can obtain two pixel-parameters values, i.e. the first pixel ginseng Number and the second pixel-parameters.In theory when being adjusted to the first pixel-parameters and the second pixel-parameters During meansigma methodss, the width of crosstalk striped reaches maximum, therefore grating pixel parameter acquiring subelement Described first pixel-parameters and the meansigma methodss of described second pixel-parameters can be calculated, by described meter Described solid when the meansigma methodss calculating cover described screen area as the width of described crosstalk striped The pixel-parameters of image.
After obtaining grating pixel correction parameter, in order to eliminate calculation error and further further Improve the accuracy of correction, can again translational movement be finely adjusted.
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 The picture crosstalk scoring that subelement 111 is used for according to calculating obtains the flat of corresponding stereo-picture Shifting amount finely tunes parameter.The interval that translational movement finely tunes parameter can be with the thick school of translational movement of acquisition Positive parameter is intermediate value, and left and right respectively sets a scope to determine.Described picture crosstalk scoring Refer to the evaluation criteria to three-dimensional picture crosstalk situation.
Specifically, adjustment translational movement is typically in the case that angle correct parameter has corrected that and completes Carrying out it is assumed that xoffadd parameter be translational movement fine setting parameter, crosstalk striped is red an IOU issued by a post office stricture of vagina, passes through Suitably adjust xoffadd parameter, so that the picture of stereo-picture is translated in the horizontal direction, move to one During individual 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.Under normal circumstances, obtain translational movement fine setting ginseng Number is carried out in the case that stereoscopic display device is opened and followed the tracks of.
When stereoscopic display device adopts optimal xoffadd parameter display stereo-picture, left and right two photographic head The stereo-picture photographing is the red and green image of pure color respectively, and red and green respectively filled with whole image Region, no hangs angle, and such beholder, when observing stereo-picture, can experience optimal 3D effect.
The trimming process of xoffadd parameter is the minima time of the direct xoffadd parameter from detection interval Go through maximum, then therefrom select the best xoffadd parameter of a spectrophotometric result.In order to accelerate to search The speed of rope 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 right Stereoscopic display device is configured.After every time equipment being configured, grabbed by filming apparatus immediately Take stereo-picture, then utilize image analysis technology to analyze the color of stereo-picture, and become according to color Change situation is adjusted to step-length, can set one according to the color value of pixel on stereo-picture here Individual crosstalk scoring, is adjusted to the change step of xoffadd parameter according to crosstalk scoring situation.Such as The crosstalk scoring of stereo-picture is very low, illustrates far apart from optimal xoffadd parameter value, so needing to increase Plus the larger numerical value of ratio, to accelerate search speed.Whereas if the crosstalk scoring of stereo-picture Higher, illustrate close to optimal xoffadd parameter value, so the smaller xoffadd of one step-length of setting Parameter value, with precise search.After the crosstalk scoring of image reaches certain threshold value, can be by now Xoffadd parameter is saved in an array, finally finds out an optimal xoffadd from this array Parameter.
Because there are left view and two images of right view in the stereo-picture that stereoscopic display device provides, please Referring 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. Figure 12 Middle circled positions, just can see stereo-picture the most bright-coloured, thus three-dimensional aobvious according to filming apparatus distance Show the difference of equipment distance, selecting optimum from multiple candidate's xoffadd parameter values can have two kinds of sides Case：
The first, when two photographic head of filming apparatus are located at optimum position, micro- translation parameterss obtain Subelement 111 obtains translational movement parameter conduct corresponding to picture crosstalk scoring highest stereo-picture Optimal translational movement fine setting parameter.In this case, the image that left side photographic head is captured is the most bright-coloured When, the image on the right should also be the most bright-coloured, so left and right stereo-picture be reach simultaneously the freshest Gorgeous degree.Optimal xoffadd parameter now exactly can make the left side (or the right) image the freshest Gorgeous xoffadd parameter value.Now only need to be according to the image of a photographic head collection it may determine that going out Good 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, or two photographic head all exist Before optimum position, or two photographic head are all placed on after optimal viewing location, refer to Figure 13 and Figure 14, Figure 13 are placed on the schematic diagram after optimal viewing location, Tu14Wei for photographic head Photographic head is placed on the schematic diagram before optimal viewing location.At this moment it is possible that：Left side photographic head Grab solid-color image the most bright-coloured, but the image that the right photographic head is captured but has not been the freshest Gorgeous solid-color image, or just contrary, and 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, micro- translation parameterss obtain subelement 111 constitute a selection region according to the xoffadd parameter being saved in array, and obtain this choosing The intermediate value selecting region is as optimal xoffadd parameter.And choose optimal from selection region Xoffadd parameter can be using different schemes, and the present embodiment provides three kinds of preferred versions：
(1) if corresponding xoffadd parameter when the image that left and right photographic head grabs reaches the most bright-coloured Difference very little, as shown in figure 15, Figure 15 is a kind of curve of the translational movement fine setting parameter array of selection Schematic diagram, in Figure 15, abscissa is xoffadd parameter value, and vertical coordinate is crosstalk score value, two songs Line is left view and the curve of right view corresponding xoffadd parameter array respectively, at this moment can take respectively The right and left image reaches the meansigma methodss of xoffadd parameter during the most bright-coloured degree (i.e. vertical coordinate is maximum) As optimal xoffadd parameter, that is, the xoffadd parameter taking dotted line position in Figure 15 is as optimal Xoffadd parameter.
(2) if corresponding xoffadd parameter when the image that left and right photographic head grabs reaches the most bright-coloured Difference is larger, and as shown in figure 16, in Figure 16, abscissa is xoffadd parameter value, and vertical coordinate is crosstalk Score value, less two curves of peak value are left view and right view corresponding xoffadd parameter number respectively The curve of group, at this moment takes the sum of the ordinate value of xoffadd parameter curve of left view and right view The corresponding xoffadd parameter of big value is optimal xoffadd parameter, will two curve vertical coordinate phases Plus, form a higher curve of peak value in Figure 16, then take the maximum pair of this curve vertical coordinate The abscissa answered is chosen to be optimal xoffadd parameter.
(3) refer to Figure 17, Figure 17 is the curve that the translational movement that another is chosen finely tunes parameter array Schematic diagram, in Figure 17, abscissa is xoffadd parameter value, and vertical coordinate is crosstalk score value, two songs Line is 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), filters out four abscissas (i.e. A, B, C, D tetra- Abscissa), the intermediate value then taking abscissa B, C or the intermediate value conduct taking abscissa A, D Optimum xoffadd parameter.
It should be noted that for different stereoscopic display devices, can be according to the solid that it is shown The concrete analysis of image is selecting calculative correction parameter, and it is not absolutely required to each school Positive parameter all carries out a calculating.For example when stereo-picture only has two vertical crosstalk stripeds, and go here and there The width disturbing striped is maximum, then only need to calculate translational movement correction parameter without calculating angle Degree correction parameter.And for example after stereo-picture calculates angle correct parameter, stereoscopic display device according to The stereo-picture that this two correction parameters show is in pure color, then need not calculate translational movement correction parameter again.
