【Specific embodiment】
The word " embodiment " used by this specification means serving as example, example or illustration.Additionally, this specification and instituteArticle " one " used in attached claim can usually be interpreted to mean " one or more ", unless otherwise orGuiding singulative is understood from context.
In embodiments of the present invention, by moving to right left-eye image, eye image is moved to left；Calculate the left eye figure after moving to rightAs and the distance between eye image after moving to left；According to the distance, blurred background image；The present invention can be by the mould of backgroundPaste degree is adjusted with the change of images of left and right eyes object parallax size so that viewing effect is seen closer to actual human eye retinaThe image for arriving, third dimension can be higher, view and admire comfort level so as to improve beholder.
In order to technical solutions according to the invention are described, illustrate below by specific embodiment.
Fig. 1 is referred to, is that three dimensional image processing method provided in an embodiment of the present invention realizes schematic flow sheet；Which is mainComprise the following steps：
In step S101, receive 3-D view, and by the 3-D view be divided into left-eye image, eye image andBackground image；
In step s 102, the left-eye image is moved to right, the eye image is moved to left；
In step s 103, the distance between eye image after calculating the left-eye image after moving to right and moving to left；
In step S104, according to the distance, the background image is obscured；
In embodiments of the present invention, according to the distance, obscure the background image the step of include：
The distance is bigger, and the fog-level for obscuring the background image is then bigger.
The distance is less, and the fog-level for obscuring the background image is then less.
In step S105, will fuzzy after the background image, move to right after left-eye image and the right eye after moving to leftImage compositing 3 d images.
In embodiments of the present invention, the background image is obscured using Gauss algorithm, is implemented as follows：
Determine blur radius；Blur radius are bigger, and fog-level is more serious, and blur radius are less, and fog-level is more seriousSlightly；
Using the central point of the pixel in the range of blur radius as origin, distribute weight according to Gauss distribution, e.g., from originThe weight that remote pixel is assigned to is bigger, and fog-level is more serious)；
According to the blur radius having determined and the weight calculation weighted mean for distributing, the weighted mean isFor value of the pixel after fuzzy；
The value after background image all pixels are obscured is calculated, the background image after Gaussian Blur is obtained.
In embodiments of the present invention, so-called " obscuring ", it is possible to understand that take the average of neighboring pixel into each pixelValue." intermediate point " takes the meansigma methodss of " surrounding point ".Numerically, this is a kind of " smoothing ".On figure, it is equivalent to produceRaw " obscuring " effect, " intermediate point " loses details.Obviously, when calculating meansigma methodss, span is maximum, and " blur effect " is strongerStrong.Blur radius are bigger, and image is fuzzyyer.From in terms of numerical value angle, it is exactly that numerical value is more smooth.Each point will take neighboring pixelMeansigma methodss, in the present embodiment, weighted average is more reasonable, and the nearer point weight of distance is bigger, and the more remote point weight of distance is less.Normal distribution is clearly a kind of desirable weight distribution pattern.As shown in Fig. 2 normal distribution is a kind of bell shaped curve, closer toCenter, value are bigger, and further away from center, value is less.When calculating meansigma methodss, it is only necessary to by " central point " as origin,Other positions according to which on normal curve, distribute weight, it is possible to obtain a weighted mean.Normal distribution closeDegree function is called " Gaussian function " (Gaussian function).Weight matrix is calculated, has weight matrix, it is possible to calculateThe value of Gaussian Blur.Each point is multiplied by the weighted value of oneself：Each value is added up, is exactly the value of the Gaussian Blur of central point.To repeating a little this process, the image after Gaussian Blur has just been obtained.If artwork is colour picture, can be to RGB tri-Individual passage does Gaussian Blur respectively.
