Specific embodiment

To keep the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with attached drawing and tool Body embodiment is described in detail.

As shown in Figure 1, a kind of image display method applied to the first equipment provided in an embodiment of the present invention, detailed process Include:

Step 101, the first equipment determines the first imaging parameters of the first image.

Wherein, the first equipment can be any one setting with image display function such as mobile phone, tablet computer, TV Standby, which is not limited by the present invention.First imaging parameters can be any imaging parameters for showing the first image, such as The color attribute parameter of one image, row's graph parameter of naked eye 3D display etc., which is not limited by the present invention.And be understood that It is that the specific picture material of the first image is equally unlimited.

Specifically, the first equipment can be according to the first imaging parameters for presetting determining first image.For example, may be used To preset the functional relation of the first imaging parameters, the first equipment can calculate the first imaging parameters according to functional relation. Certainly, the parameter value of the first imaging parameters is also possible to by equipment hair except the first equipment, with the communication connection of the first equipment Give the first equipment.

Step 102, the first equipment determines mark bit map picture corresponding with the first imaging parameters of the first image.

It is emphasized that the first imaging parameters of mark bit map picture and the first image have corresponding relationship, this correspondence Relationship can be it is directly corresponding be also possible to it is indirectly corresponding.So-called direct correspondence refers to that mark bit map picture directly indicates The parameter value of one imaging parameters, and so-called indirect correspondence refers to, mark bit map picture indicates some information, and can by the information To obtain the first imaging parameters.For example, the first imaging parameters are the functions about picture number, it is available according to picture number First imaging parameters, mark bit map picture are used to refer to picture number, and then after knowing picture number by mark bit map picture, i.e., Available first imaging parameters.

Step 103, the first equipment generates the first image, and will be with the first figure according to the first imaging parameters of the first image The predetermined position in the first image is arranged in the corresponding mark bit map picture of first imaging parameters of picture.

Wherein, predetermined position is unlimited, can be any position in the first image, in order to facilitate the crawl of mark bit map picture And identification, mark bit map picture can be arranged in the center of the first image.

Step 104, the first equipment shows the first image for being provided with mark bit map picture, so that the second equipment obtains the first figure Picture, and according to the mark bit map picture being arranged in the first image, determine the first imaging parameters of the first image.

Image display method provided in an embodiment of the present invention, since mark bit map picture is arranged in the first equipment in the first image And there are corresponding relationships for the first imaging parameters of mark bit map picture and the first image, and therefore, the second equipment can synchronize acquisition To the first image and mark bit map picture, and then the first imaging parameters of the first image are accurately obtained by mark bit map picture, i.e., It is equivalent to the first imaging parameters that are synchronous and accurately obtaining the first image and the first image.So, the first equipment is practical First imaging parameters of any image of display can accurately be identified by the second equipment, effectively prevent the second equipment The nonsynchronous problem of the first imaging parameters for the first image that the first image got and the second equipment determine, solves existing The technical issues of side that image is got present in technology more can not accurately know the image parameter of image.

It is described further below for above method process.

In above method process, the first imaging parameters of the first image can be the display that image is shown with the first equipment It can any one relevant imaging parameters.For example, the first equipment can be naked eye 3D display equipment, and the second equipment can be use In the calibration equipment for the first imaging parameters for correcting the first equipment, rear extended meeting is described in detail by specific embodiment.

In a kind of specific embodiment, the first imaging parameters can be the function of picture number, and mark bit map picture be used to Picture number is identified, specifically, picture number can be frame number.For example, circulation is shown several frame images by the first equipment, it is each Frame image applies first imaging parameters, and the first equipment first can be according to presetting or by logical with external equipment Letter, determines the initial value of the first imaging parameters and the rule change of the first imaging parameters, for example, one frame image of every display, the One imaging parameters increase a fixed step-length, i.e. the first imaging parameters are the function of frame number.

In this case, before the first imaging parameters that step 101 determines the first image, above method process is also wrapped It includes: determining the picture number of the first image；Then, above-mentioned steps 101 specifically include: according to the picture number of the first image, determining First imaging parameters of the first image；Above-mentioned steps 102 specifically include: according to the picture number of the first image, determining flag bit Image, mark bit map picture is used to identify the picture number of the first image, so that the mark bit map picture of the first image and first First imaging parameters of image are corresponding.Because the picture number of the first image and the first imaging parameters of the first image exist one by one Corresponding relationship, the mark bit map picture of the first image are used to identify the picture number of the first image, therefore, the flag bit of the first image There are corresponding relationships for first imaging parameters of image and the first image.

In a kind of specific embodiment, mark bit map picture includes more intuitive digital picture.For example, as shown in Figure 2 The first image, including one show content be " 2 " mark bit map picture, the mark bit map image position is in the bottom right of the first image Angle, the frame number for identifying first image are 2, and the second equipment is after obtaining first image, as long as identifying number It determines the frame number of the first image, and then according to the frame number of the first image, determines the first imaging parameters of the first image.

In a kind of specific embodiment, for the ease of the mark bit map picture in the first image of identification, the present embodiment mode Devise a kind of cleverly mark bit map picture.The mark bit map picture includes at least one region, generally at least two regions, no Same regional location is different, and the position in region is used to identify the numerical digit of predetermined system, it is to be understood that different numerical digits are corresponding Different weights, wherein scheduled system can be the decimal system, binary system, hexadecimal etc., which is not limited by the present invention, And the color in region is used to identify the numerical value of numerical digit.In this case, above-mentioned steps 102 specifically include: according to first figure The picture number of picture determines the hex value that described image is numbered under the predetermined system；According to each numerical digit in the hex value Numerical value, determine in the mark bit map picture color in region corresponding with each numerical digit respectively；According in the mark bit map picture The color in region corresponding with each numerical digit respectively determines the mark bit map picture.

Wherein, numerical value represented by mark bit map picture is not limited to decimal value, can be the numerical value of a variety of systems, referred to as Hex value.No matter the numerical value that mark bit map picture indicates why system, the decimal value of the numerical value and the numerical value can be by as follows Relationship converts:Wherein, N indicates decimal value corresponding to mark bit map picture, X_iFor mark bit map The numerical value of the numerical digit of represented system number as in, K are that (binary system, K are just 2) k to system^n-iRepresent the corresponding weight of numerical digit, n For the quantity in the region in mark bit map picture, and i ∈ (0,1,2 ..., n).

For example, mark bit map picture shown in Figure 3, it is assumed that predetermined system is binary system, i.e. flag bit image table Show a binary number.Mark bit map picture is divided into upper left, lower-left, upper right, the region of bottom right 4, and each region can be filled black, white 2 Kind color, black are used to identification value 0, and white is used to identification value 1.4 regions indicate 4 numerical digits, upper left indicate 4 two into First of number processed, upper right indicate the second of 4 bits, and lower-left indicates that the third position of 4 bits, bottom right indicate The 4th of 4 bits.Different numerical digits corresponds to different weights, the decimal value which indicates are as follows: n₁×2³+n₂×2²+n₃×2¹+n₄×2⁰.For example, when top left region is black, indicate that the numerical value of the numerical digit is 1, i.e. n₁ =1, and top left region be white when, indicate the numerical digit numerical value be 0, i.e. n₂=0, other numerical digits are identical with this.

By taking above-mentioned exemplary mark bit map picture is used to identify the frame number of the first image as an example, the first equipment determines the frame first Number hex value (i.e. binary value) determine mark bit map as each region then according to the value of numerical digit each in the binary value Color, so that it is determined that going out mark bit image.When the frame number of the first image is 1, four of the frame number of the first image under binary system Binary value is 0001, i.e. n₁=n₂=n₃=0, n₄=1, i.e. the first of four 2 hex values, second, third position, Four corresponding regions should fill respectively it is black, black, black, white so that constitute mark bit map picture indicate frame number be 1.Root According to the position in each region in 4 regions and the corresponding relationship of each numerical digit, and the color in region corresponding with each numerical digit respectively, each The color that the area filling region should fill, and then can determine that the mark when frame number of the first image is 1 in first image Bit image, reference can be made to shown in Fig. 3.If first, second, third position, the 4th corresponding zonule fill respectively it is black, black, Frame number white, black, then that the mark bit map picture that 4 zonules are constituted indicates are as follows: 0 × 2³+0×2²+1×2¹+0×2⁰=2.

It is understood that in other embodiments, the system of numerical value represented by mark bit map picture is unlimited, Ke Yiwei The arbitrary carry systems such as the decimal system, octal system, hexadecimal, it is right that the position distribution mode in region is not limited to above-mentioned upper left upper right lower-left Lower distribution, can also be horizontal left and right sequentially distribution, it is vertical up and down sequentially distribution, circular distribution, array distribution etc. any one The setting of distribution mode, regional location and numerical digit corresponding relationship is not limited to above-mentioned setting, can also be arranged otherwise, example Such as, mark bit map picture shown in Fig. 3 respectively corresponds high flexible strategy position to the low flexible strategy position of hex value from top to bottom from right to left.

It should also be noted that, for clarity, each area limit of mark bit map picture shown in Fig. 3 is brighter It is aobvious, but in actual implementation, if the boundary between region may be subjected to influence after adjacent area fills same color, two Perhaps, a area limit line can not be distinguished clearly.

In the mark bit map picture of above-mentioned example, including 4 regions, but the quantity in the mark bit map picture region that includes is unlimited, It can be configured according to the numerical intervals of expression required for mark bit map picture.In this specific implementation, in mark bit map picture The position in each region is used to identify the numerical digit of predetermined system, and the color in region is used to identify the numerical value of numerical digit, different colors Represent different numerical value.It is understood that the region that the numerical value and mark bit map picture that are represented with mark bit map picture are divided into Quantity is related, is 0 to 15 with the numerical value that 2 systems (2 kinds of Fill Colors) can indicate if being divided into 4 regions；When needs pair It when numerical intervals are extended, can be extended with the quantity in region, mark bit map picture is such as divided into 6 regions, then 62 For the numerical value of the numerical digit of system with 0 or 1 label, the numerical value that can be indicated is 0 to 63 (1 × 2⁵+1×2⁴+1×2³+1×2²+1×2¹+ 1×2⁰=63).

It is understood that it is also related with system with the size of the numerical value of mark bit map picture representative, and system is filled out with region The quantity for the color filled is corresponding, and the color of area filling has 2 kinds under binary system, and the color of area filling has 4 kinds under the quaternary, And so on；It can be to increase the color of area filling by adjusting system to realize pair if the quantity of holding area is constant The extension of numerical intervals representated by mark bit map picture.For example, setting if mark bit map picture indicates 2 system numbers with black, white 2 kinds Color respectively indicates numerical value 0,1.If the region that mark bit map picture is divided into is 5, numerical digit is 5, then being capable of table with 2 systems The numerical intervals shown are 0 to 31, maximum value are as follows: 1 × 2⁴+1×2³+1×2²+1×2¹+1×2⁰=31.If setting mark bit map picture It indicates 4 system numbers, 4 kinds of colors can be used: it is black, white, green, green to respectively indicate numerical value 0,1,2,3, if mark bit map is as being divided into Region is 5, and numerical digit is 5, then is 0 to 1023 with the numerical intervals that 4 systems can indicate, maximum value indicates are as follows: 3 × 4⁴+3 ×4³+3×4²+3×4¹+3×4⁰=1023.

Therefore, those skilled in the art can the expression according to required for mark bit map picture numerical intervals, be arranged flag bit The region quantity of image corresponding system and mark bit map picture.Moreover, if necessary to numerical value area representated by mark bit map picture Between size when being adjusted, by setting mark bit map as divided region quantity and/or system size (mark bit map The number of colors of each area filling as in), the range of numerical intervals representated by mark bit map picture can be adjusted.

After determining mark bit map picture, in step 103, the first equipment can be first according to the first of the first image the imaging Parameter generates the first image, is then combined to determining mark bit map picture with the first image, so that mark bit map picture is arranged In the first image.At step 104, the first image for being provided with mark bit map picture is shown.

So, the second equipment, which can synchronize, gets the first image and mark bit map picture, and then accurately passes through mark Will bit image obtains the first imaging parameters of the first image, that is, synchronizing and accurately obtaining the first image and the first image The first imaging parameters.Obviously, the first imaging parameters of any image of the first equipment actual displayed, can be by the second equipment It accurately identifies, effectively prevents the first of the first image that the second equipment is got and the first image that the second equipment determines The nonsynchronous problem of imaging parameters, solving the side existing in the prior art for getting image more can not accurately obtain The technical issues of knowing the image parameter of image.

In practical application, image display method provided in an embodiment of the present invention can be applied to the first imaging to the first equipment In the analysis and correction of parameter.Under this application scenarios, simplified summary is said, the first equipment is needed using multiple and different first Imaging parameters generate and show multiple first images, and the second equipment needs to obtain this multiple image and this multiple image is right respectively The first imaging parameters answered, and this multiple image is analyzed, so that analysis obtains optimal first that the first equipment is applicable in Imaging parameters value.Based on this, in a specific implementation of the invention, image display method provided by the invention further includes following Step:

First equipment generates and shows that the specific process of the second image can be found in the first equipment in above-described embodiment and generate And show the detailed process of the first image, it is not repeated herein.

By taking image display method provided in an embodiment of the present invention is applied in the correction course of naked eye 3D equipment as an example at this moment, One equipment is naked eye 3D display equipment, and the second equipment is calibration equipment, and the first imaging parameters are that Xoffadd (also referred to as claps figure ginseng Number).The process for correcting the Xoffadd of naked eye 3D display equipment is the process of a searching loop, naked eye 3D display equipment circulation Show that it is aobvious that calibration equipment obtains naked eye 3D display equipment circulation based on the image generated according to the Xoffadd of certain rule variation The image shown, and determine according to the mark bit map picture being arranged in image the Xoffadd of image, and according to these images and these figures As Xoffadd determines the Xoffadd suitable for naked eye 3D display equipment, to realize the purpose of correction.Using of the invention real The image display method of example offer is applied, the first imaging parameters of any image of naked eye 3D display equipment actual displayed all can be by Calibration equipment accurately identifies, on the one hand, efficiently solves naked eye 3D display equipment actual displayed existing in the prior art Image asynchronous with the first imaging parameters to be corrected of calibration equipment to 3D display device talk corresponding may cause to correct The problem that precision is not good enough.On the other hand, calibration equipment is not needed to recycle to display equipment transmission Xoffadd value, naked eye 3D display Equipment can change Xoffadd value according to preset rules, such as can effectively reduce in this way from a fixed step-length is increased every time Communication interaction between calibration equipment and naked eye 3D display equipment saves interaction cost.

Above-mentioned specific implementation is to be illustrated by taking Xoffadd as an example, but the first imaging parameters are without being limited thereto, can be with naked eye Any parameter for being used to be imaged display of 3D display equipment.

It is corresponding with aforementioned display methods embodiment based on identical inventive concept, the embodiment of the present invention also provide one Kind is applied to the image analysis method of the second equipment, wherein the second equipment can be any one tool such as mobile phone, personal computer There is the equipment of data processing function, which is not limited by the present invention, as shown in figure 4, image analysis provided in an embodiment of the present invention Method, detailed process include:

Step 401, the second equipment obtains the first image that the first equipment is generated and shown, the predetermined position in the first image On be provided with mark bit map picture.

Wherein, the first equipment generates according to the first imaging parameters of the first image and shows the first image, on the first image The mark bit map picture of setting and the first imaging parameters of the first image are corresponding.

It should be noted that the display process and mark bit map picture of the first equipment are described in detail above, Here it will not be described in great detail.

Specifically, the second equipment may be provided with camera, in this step, the second equipment shows the by camera shooting The photo of first equipment of one image, for example, the photo of the screen of the first equipment of shooting, generates and show to obtain the first equipment The first image shown.

Certainly, the second equipment can also get the first image by other means, and which is not limited by the present invention.

Step 402, the second equipment determines the first imaging of the first image according to the mark bit map picture being arranged in the first image Parameter.

In a kind of specific embodiment, the first imaging ginseng of the mark bit map picture and the first image that are arranged on the first image Number is corresponding to be referred to: the first equipment determines the first imaging parameters of the first image, mark bit map picture according to the number of the first image For identifying the picture number of the first image, so that the first of the mark bit map picture and the first image that are arranged on the first image is imaged There are corresponding relationships for parameter.In this case, above-mentioned steps 402 specifically include: extracting and indicate from the predetermined position of the first image Bit image；According to the mark bit map picture of extraction, the picture number of the first image is determined；According to the picture number of the first image, really First imaging parameters of fixed first image.

Position of the mark bit map picture in the first image be it is pre-set, the second equipment predicts the predetermined position.For Mark bit map picture is extracted from the first image, the second equipment can determine mark bit map in the first image according to predetermined position first Then the approximate location of picture extracts mark bit map picture according to the approximate location.Specifically, the second equipment is from the pre- of the first image Extraction mark bit map picture is set in positioning

According to predetermined position, determine that the first area in the first image, first area include mark bit map picture；From the first figure The image of first area is extracted as in.

Due to position of the mark bit map as shown in the display screen of the first equipment be it is fixed, i.e., in the first image Position be it is fixed, therefore, mark bit map picture is also relatively solid in approximate location of second equipment in the image that camera grabs It is fixed.Assuming that the display position of mark bit map picture is the square area of center positive and negative 50 pixels up and down of the first image. When second equipment shoots the first image by camera, the position of the mark bit map picture of the image of crawl also should be in the figure of crawl The central area of picture, flag bit image-region should the picture centre captured by the second equipment relative to above-mentioned square area In the high region of 2--3 times of width.It thus can tentatively extract a rough region --- first area, the region include Mark bit map picture.The image acquiring device of the second equipment and the image display device of the first equipment can be effectively avoided in this way Height or position have caused second equipment when deviation to be difficult to extract mark bit map picture from the first image that the first equipment is shown The problem of.

Then, Threshold segmentation is carried out to the image of the first area of extraction.

The purpose of Threshold segmentation is for the edge contour of rising mark bit image.Cheng Yu can be set in mark bit map picture One image itself has the color of significant difference.When carrying out Threshold segmentation, typically refer to carry out threshold value using the gray value of pixel Segmentation, the gray value of pixel is usually between 0 to 255, when the image in the first area to extraction carries out Threshold segmentation, can incite somebody to action Threshold value is set as 100, and the pixel grey scale by gray value less than 100 is set as 0, and the gray scale of the pixel by gray value greater than 100 is set as 255.Image after carrying out Threshold segmentation to the image of the first area of extraction is just called bianry image, i.e., just there was only two in image Kind gray value: it is white and black, so as to which the mark bit map picture in the image of the first area of extraction is come with background separation.

The determination of approximate region and Threshold segmentation processing are the preextraction of mark bit map picture, and the preextraction stage is to drop The difficulty of low flag bit image zooming-out.Next, will accurately be extracted to mark bit map picture, from the firstth area after Threshold segmentation The edge contour of mark bit map picture is detected in the image in domain, to extract from the image of the first area after Threshold segmentation Mark bit map picture.It can be in the following way to the accurate extraction of mark bit map picture:

Using the contour detecting algorithm of prior art routine, such as OpenCV contour detecting function is to the flag bit of preextraction Image-region carries out contour detecting, to obtain the general profile of mark bit map picture.Due to the picture material of the first image itself Influence, therefore, in the profile that contour detecting obtains in addition to the profile of mark bit map picture there is likely to be other interfere profile. Since the elemental area of mark bit map picture is the fixed value pre-set, and the chamfered shape of mark bit map picture is also preparatory It is arranged, therefore can carries out profile screening according to the shape of the fixed value and mark bit map picture, exclude interference profile.Mark Will bit image shape is usually arranged as polygon, for example, quadrangle, due to the mark bit map picture that detected profile not It is standard polygonal shape, it, can be right according to pre-set flag bit image shape therefore, it is necessary to be further processed The remaining profile progress polygonal segments processing after interference profile is excluded, to obtain the precise boundary position of mark bit map picture It sets.And then according to obtained precise boundary position, mark bit map picture is extracted from the first image.Such as mark bit map picture is Quadrangle, which is the pixel coordinate of four angle points of quadrangle, according to the pixel coordinate of four angle points, from The mark bit map picture of quadrangle is extracted in first image.

In the case where mark bit map picture is digital picture, the second equipment extracts mark bit map picture, then according to The mark bit map picture extracted, identifies the number in mark bit map picture, to determine the first image according to the number of identification Picture number.Number identification can use existing well-known technique, and which is not described herein again.

It include at least one region in mark bit map picture, the position in region is used to identify the numerical digit of predetermined system, region In the case that color is used to identify the numerical value of numerical digit, the second equipment extracts mark bit map picture, determines the mark bit map picture extracted In at least one region color；According to the color at least one region, the number of numerical digit corresponding at least one region is determined Value；According to the numerical value of numerical digit, the hex value of picture number under predetermined system is determined；According to the system of picture number under predetermined system Value, determines the picture number of the first image.

Wherein it is determined that extract mark bit map picture at least one region color, specifically include: from mark bit map picture It is partitioned into the image at least one region；Extract the pixel value of the pixel in predetermined position at least one region being partitioned into； The average pixel value for calculating the pixel value of the pixel extracted, using average pixel value as the color value in region.

Wherein, the image at least one region is partitioned into from mark bit map picture, comprising: will indicate according to preset The position of the quantity in the region of bit image and each region in mark bit map picture, mark bit map picture is divided, and is obtained each The image in a region, for example, if the quantity of the flag bit area of mark bit map picture is 4, according to the upper left of mark bit map picture, a left side Under, upper right, bottom-right location, the mark bit map picture of extraction is averagely divided into the image in 4 regions.

Wherein, the pixel value of the pixel in predetermined position at least one region being partitioned into is extracted, comprising: for segmentation The image of any region out extracts the image slices vegetarian refreshments being sized in range centered on the central point in the region, example Such as the pixel within the scope of central point 3*3；Determine the pixel color average value for the image slices vegetarian refreshments that will be sized in range；Meter The average pixel value for calculating the pixel value of the pixel extracted, using average pixel value as the color value in region.Alternatively, calculating average The Euclidean distance between any color value in pixel value and designated color will be determined as this apart from the pixel value of the smallest color The color value of the image in region, wherein specified color refers to the color for representing the numerical value of each numerical digit in mark bit map picture.

For example, pixel color, RGB are extracted within the scope of heart point 3*3 in the picture for the image for any region being partitioned into Then value or gray value calculate the average pixel value of the pixel value of pixel within the scope of 3*3, with pixel within the scope of 3*3 The average pixel value of pixel value is as seed point color value.Calculate any color value in seed point color value and designated color it Between Euclidean distance, the color value of the image in the region will be determined as apart from the pixel value of the smallest color.

It is exemplified below.Mark bit map picture as shown in Figure 3, the mark bit map picture indicate 4 bits, including 4 Region, upper left, right regions and lower left region are black, and lower right area is white, black table registration value 0, white expression numerical value 1.Second equipment identifies the color in this four regions respectively, and determines this corresponding numerical digit in four regions according to color Numerical value then according to the corresponding weight of each numerical digit, carry out decimal system conversion, determine to obtain a binary value 0001 The picture number of the first image is 1 out.

For another example mark bit map picture indicates 4 bits, including 4, first to fourth region region, black table registration Value 0, white indicate numerical value 1.Second equipment determine first area, second area, third region, the fourth region color be respectively It is black, white, black, white, it is determined that first area, second area, third region, the corresponding numerical digit of the fourth region numerical value be respectively 0, 1,0,1.If first area, second area, third region, the corresponding numerical digit of the fourth region be respectively binary number from back to front 1st, the 2nd, the 3rd, the 4th, then the 1st corresponding weight is with 2⁰It indicates, the 2nd corresponding weight is with 2¹It indicates, the 3rd The corresponding weight in position is with 2²It indicates, the 4th corresponding weight is with 2³Indicate, then under predetermined system picture number hex value 0101 is scaled the decimal system are as follows: 0 × 2³+1×2²+0×2¹+1×2⁰, then according to the hex value of picture number under predetermined system, really The picture number of the first fixed image is 5.

After second equipment obtains picture number, by according to the picture number of the first image, the first one-tenth of the first image is determined As parameter.Picture number and the first imaging parameters have certain functional relation, can utilize picture number according to functional relation Obtain the first imaging parameters.For example, picture number is related to number is looped through for example, in a specific embodiment, First equipment circulation display the first image, cycle-index be first time when, the first image parameter be initial value, picture number 1, When recycling second, picture number 2, the first imaging parameters increase by fixed step-length a ... circulation on the basis of initial value N-th is picture number N, and value of first imaging parameters when recycling for previous i.e. N-1 time on the basis of increases the step of the fixation It is long.The every circulation display of first equipment is primary, and the second equipment the first image of acquisition is primary, i.e. the second equipment executes a searching loop The behavior of image.Obviously, mark bit map picture indicates picture number, and picture number is equal to searching loop number, known first In the case where the initial value of image parameter, the second equipment can obtain first image of each the first image according to picture number Parameter.

First equipment and the second equipment can arrange rule of communication, and the circulation ginseng of the first equipment is arranged in the rule of communication of agreement Several traversal parameters with the second equipment, the traversal parameter of the first equipment, such as initial cycle number (i.e. the second equipment of the first equipment Traversal number), the initial value of the first imaging parameters and the first imaging parameters when cycle-index is incremented by with walking from increasing It is long.After first equipment carries out initialization starting circulation process, one frame image of every display, cycle-index is incremented by, and the first equipment is shown Frame number (i.e. picture number) of the cycle-index as the first image when showing the first image, therefore, the second equipment is according to flag bit After image determines the frame number of the first image, according to the rule of communication of agreement, so that it may determine that the first equipment shows the first figure As when the first imaging parameters.

In specific application for above method process, the first equipment successively shows each frame figure according to self-loopa process First imaging parameters of picture, each frame image that the second equipment successively shows the first equipment according to self-loopa process are known Not.First equipment shows several frame images, the first imaging parameters of each frame image that the second equipment shows the first equipment into Row identification, and then the second equipment can determine the first optimal imaging ginseng of the first equipment from several first imaging parameters Number.

That is, the second equipment, which needs to recycle, obtains multiple first images, it is based on this, it is specific real at of the invention one Shi Zhong, image analysis method provided by the invention are further comprising the steps of:

The second image that the first equipment is generated and shown is obtained, is provided with mark bit map on the predetermined position in the second image Picture；

According to the mark bit map picture being arranged in the second image, the first imaging parameters of the second image are determined.

Image analysis method provided in an embodiment of the present invention can be applicable to the correction course of naked eye 3D equipment.Existing imaging ginseng In several correction courses there is calibration equipment determine imaging parameters it is asynchronous with the image of 3D display equipment actual displayed, lead The problem for causing correction result inaccurate.In order to solve this problem, in a kind of specific embodiment, the first equipment is naked eye 3D display equipment, the grating including display screen and setting on a display screen, the second equipment is calibration equipment, and the first imaging parameters are Any key parameter of naked eye 3D display equipment, such as Xoffadd.After naked eye 3D display equipment shows the first image, correction Equipment determines the first imaging parameters of the first image according to the mark bit map picture being arranged in the first image, and 3D display equipment shows After two images, calibration equipment determines the first imaging parameters of the second image according to the mark bit map picture being arranged in the second image, according to This analogizes.

The imaging parameters that calibration equipment can be made to determine by above method process, it is practical aobvious with naked eye 3D display equipment The imaging parameters of the image shown are consistent, and the first imaging parameters of any image of 3D display equipment actual displayed can be all corrected Equipment accurately identifies, and then on the other hand, it is practical aobvious to efficiently solve naked eye 3D display equipment existing in the prior art The image shown asynchronous with the first imaging parameters to be corrected of calibration equipment to 3D display device talk corresponding may lead to school The not good enough problem of positive precision.

Below with reference to the correct application scene of naked eye 3D display equipment, using the first equipment as naked eye 3D display equipment, second Equipment is calibration equipment, and the first imaging parameters are for arranging graph parameter xoffadd value, to show to picture provided in an embodiment of the present invention Show that method and picture analyzing method are further elaborated.Wherein, naked eye 3D display equipment includes that display screen and setting exist Grating on display screen.As shown in figure 5, specifically including:

Step 1, calibration equipment sends the rule of communication of agreement to naked eye 3D display equipment；

Calibration equipment starts correction program first, and after initialization, the rule of communication of agreement is sent to naked eye 3D display equipment.

Wherein, include: in the rule of communication of agreement

The initial value picth=6.64241 of graph parameter xoffadd is arranged, row graph parameter xoffadd's increases step-length certainly Xoffadd_step=0.2 is looped through number Iter=200 (maximum frame number)；

Predetermined system is 4 systems (i.e. mark bit map picture includes 4 regions)；

The color in region includes black, white, indigo plant, green, respectively represents numerical value 0,1,2,3；

The display area of the mark bit map picture heart in the picture, a height of 100*100 pixel of the width of display area；

The position in each region of mark bit map picture and the corresponding relationship of numerical digit are as follows: mark bit map as upper left region be four into Number processed from back to front the 1st, the region in upper right side is the 2nd, and the region of lower left is the 3rd, and the region of lower right is the 4th Position.

It is understood that optional, full content or department's content in rule of communication can also in the first equipment and Preset and store in second equipment, can not through this embodiment in the mode of this communication transmit.

Step 2: naked eye 3D display equipment receives the rule of communication for the agreement that calibration equipment is sent, and according to the communication of agreement Rule is initialized；

The starting of naked eye 3D display equipment receives the rule of communication of agreement, and according to the various parameters in the rule of communication of agreement It is initialized.

Step 3, calibration equipment sends correction instruction, instruction naked eye 3D display equipment starting traversal to naked eye 3D display equipment The circulation process of xoffadd value；

Step 4, naked eye 3D display equipment receives correction instruction, starts the traversal self-loopa process of xoffadd value, for working as Preceding traversal number executes following steps:

Determine the frame number of correction image；

Determine the xoffadd value of correction image；

According to the frame number of correction image, mark bit map picture is determined；

Correction image is generated according to the xoffadd value of correction image, and determining mark bit map picture is arranged in correction chart Show that this is provided with the correction image of mark bit map picture behind the predetermined position of picture；

Wherein, in currently traversal number, when generating and showing correction image, it is determined as current traversal number to correct image Frame number, for example, currently traversal number be 27, then current frame number be 27；According to xoffadd_step value in upper traversal number When xoffadd value on the basis of from increase an xoffadd_step value, determine currently to traverse the corresponding xoffadd of number Value, for example, the xoffadd value of upper traversal number is 3.0, it is determined that the current corresponding xoffadd value of number that traverses is 3.2； Determine mark bit map as when, if currently traversal number be 27, then it is determined that the corresponding hex value of frame number 27 be 0123, i.e., 0 × 4³+1×4²+2×4¹+3×4⁰；The numerical value for then determining each numerical digit in mark bit map picture when frame number is 27 is respectively 3, 2,1,0, then the color that the corresponding region of each numerical digit should fill is respectively green (first), blue (second) is white (third position), Black (the 4th)；Corresponding color is filled in each region, the mark bit map picture that frame number is 27 can be generated, as shown in Figure 6；It is raw The correction image for being 3.2 at xoffadd value, and determining mark bit map picture is arranged in the center for correcting image, so that After correction image with mark bit map picture is shown, a height of 100*100 of viewing area field width of mark bit map picture, naked eye 3D display is set The correction image with mark bit map picture of standby display is as shown in Figure 7.

Step 5, determine whether current traversal number is greater than maximum traversal number and will currently traverse number if being not more than From increasing, next traversal number is obtained, above-mentioned steps are executed in next traversal number, if more than then terminating to traverse；

Step 6, calibration equipment starts self-loopa program, and the naked eye 3D display of correction image is shown by camera shooting The photo of equipment, such as the photo of display device screen part；

For each photo taken, following steps are executed:

Mark bit map picture is extracted from the predetermined position of correction image；According to the mark bit map picture of extraction, correction image is determined Frame number；According to the frame number of correction image, the xoffadd value of correction image is determined；

Since the relative position of calibration equipment and naked eye 3D display equipment is fixed, therefore it may only be necessary to which calibration equipment is got The position for indicating bit image in one frame image, can be obtained the position of the mark bit map picture of each frame image, also can be according to this Position directly extracts mark bit map picture from each frame image.The first frame figure shown generally according to naked eye 3D display equipment Picture, to determine the position of each frame correction image acceptance of the bid will bit image.

For example, extracting mark from the predetermined position of first frame correction image when calibration equipment obtains first frame correction image Will bit image, specifically includes: according to predetermined position (central area 100*100 pixel), determining the in first frame correction image One region, first area include mark bit map picture；From first frame correction image, the image of first area is extracted；To extraction The image of first area carries out Threshold segmentation；The side of mark bit map picture is detected from the image of the first area after Threshold segmentation Edge profile, to extract mark bit map picture from the image of the first area after Threshold segmentation.Determine edge contour It determines position of 4 angle points of mark bit map picture in first frame correction image, saves the location information of this 4 angle points, after When afterflow journey carries out the extraction of other frames correction image acceptance of the bid will bit image, all in accordance with the location information of this 4 angle points of preservation To extract the mark bit map picture in correction image.

After extracting mark bit map picture, mark bit map picture is divided into 4 according to the rule of communication of agreement by calibration equipment The image in region extracts pixel color, rgb value for the image for any region being partitioned into the picture within the scope of heart point 3*3 Or gray value, the average pixel value of the pixel value of pixel within the scope of 3*3 is then calculated, with the picture of pixel within the scope of 3*3 The average pixel value of element value is as seed point color value.It calculates between any color value in seed point color value and designated color Euclidean distance, the color value of the image in the region will be determined as apart from the pixel value of the smallest color.If first area, second Region, third region, the color of the fourth region are respectively green, blue, white, black, first area, second area, third region, the 4th The corresponding numerical digit in region is the 1st, the 2nd, the 3rd, the 4th；Then the 1st, the 2nd, the 3rd, the 4th numerical value be respectively 3,2,1,0, i.e. the hex value of the frame number of flag bit image identification is 0123, carries out decimal system conversion, determines mark bit map picture Corresponding frame number is 27, i.e. 27=0 × 4³+1×4²+2×4¹+3×4⁰.Finally closed according to frame number 27 is corresponding with xoffadd value System, determines the corresponding xoffadd value of frame number 27, xoffadd value=initial value+(frame number -1) * step-length of each frame image.

Step 7: judge whether the value of frame number is greater than defined maximum frame number, if more than then terminating to traverse, executing step: 8；If being not more than, above-mentioned steps are continued to execute.

Step 8: calibration equipment determines optimal xoffadd value from multiple xoffadd values.

For example, calibration equipment simulation human eye determines the display effect for each frame image that naked eye 3D display equipment is shown, The display effect that image is corrected according to each frame gives a mark to xoffadd value corresponding to each frame correction image, by all frames It corrects marking in image and is worth highest xoffadd value as optimal xoffadd value.

How the present invention is for from multiple xoffadd values to determine optimal xoffadd value without limitation, this field skill Art personnel can use existing well-known technique.

Above method process compared with prior art, has following technical effect that

First, the interaction of above-mentioned limited times has only been carried out between naked eye 3D display equipment and calibration equipment, and the prior art In the correction of each xoffadd value require the communication at both ends and could complete, if traversal number is 200, in the prior art It at least carries out communicating and could completing for 200 times between naked eye 3D display equipment and calibration equipment, and the present invention only needs to carry out 10 times Within communication can complete 200 corrections, therefore compared with prior art, display methods provided by the invention and analysis Method can be reduced the frequent communication of line end to a certain extent, improve the correction efficiency of 3D display equipment row's graph parameter.

Second, looping through xoffadd value, each xoffadd from step-length is increased according to row's graph parameter in 3D display equipment It is worth a corresponding circulation frame number, the corresponding frame of a circulation frame number corrects image, each in order to parse calibration equipment The circulation frame number for correcting image, a mark bit map picture, which is arranged, in the predetermined position of correction image indicates previous cycle frame number, base In the mark that the corresponding circulation frame number of xoffadd value can be converted to by rule of communication, the player end of 3D display equipment Bit image；Then calibration equipment obtains the correction image currently shown by camera, extracts the mark being arranged in correction image Bit image parses previous cycle frame number according to the mark bit map picture of extraction, determines correction image according to previous cycle frame number Corresponding xoffadd value.So that calibration equipment accurately parses the corresponding xoffadd value of each frame correction image, last basis The display effect of all frame correction images accurately calculates optimal xoffadd value, the correction accuracy of the row's of improving graph parameter.

Third, above method process realizes the first imaging ginseng of any image of 3D display equipment actual displayed Number, can all be corrected equipment and accurately identify, solve in the correction course of existing imaging parameters that there is calibration equipments It is nonsynchronous with the imaging parameters of the image of 3D display equipment actual displayed with the imaging parameters to be corrected of 3D display device talk Problem.
