The naked-eye 3D implementation method provided in the embodiment of the present application will be specifically described below with reference to fig. 1 to fig. 2.
Exemplarily, fig. 1 is a schematic flow diagram of a naked eye 3D implementation method provided in an embodiment of the present application. As shown in fig. 1, the naked eye 3D implementation method includes the following steps:
and S11, acquiring the positions of the two eyes of the user on the viewpoint of the screen.
In the embodiment of the application, the positions of the viewpoints of the two eyes of the user on the screen can be tracked through the eye tracking module. In particular, the information of the viewpoint located on the screen may be collected based on an eye tracker. The viewpoint information may include viewpoint position coordinates of both eyes of the user on the screen.
Optionally, the naked eye 3D implementation method provided in the embodiment of the present application may further include the following steps:
s101, a left eye image and a right eye image are acquired.
Wherein the left-eye image and the right-eye image are both 2D images. The left-eye image and the right-eye image correspond to images captured by a single eye when the left eye and the right eye simultaneously look at an object. The left-eye image and the right-eye image may be a photograph and a video source photographed by a 3D camera, or may be a film source or a 3D game algorithmically converted into 3D from a 2D photograph or a 2D video.
And S102, carrying out transparentization treatment on the left-eye image or the right-eye image at a preset ratio.
Specifically, the preset ratio may be 50%, that is, the left-eye image or the right-eye image is subjected to 50% transparency processing. Of course, in other embodiments, the preset ratio may also be other values, and the application is not limited in particular.
Fig. 2 is a schematic diagram of an overlapped image displayed on a screen provided in the embodiment of the present application, and as shown in fig. 2, the processed left-eye image is marked as v1, and a center point thereof is marked as p 1; the right eye image remains unchanged, labeled v2, with its center point labeled p 2.
S103, the processed left eye image is placed above the right eye image or the transparent processed right eye image is placed above the left eye image, and the center point of the left eye image is coincident with the center point of the right eye image.
The transparentized image is placed on top of another image which is not subjected to transparentization. That is, the transparentization-processed left-eye image v1 is placed above the non-transparentization-processed right-eye image v2 or the transparentization-processed right-eye image v2 is placed above the non-transparentization-processed left-eye image v1, and p1 and p2 are overlapped.
And S104, displaying an output overlapped image on a screen, wherein the center point of the left eye image and the center point of the right eye image in the overlapped image are both positioned in the center of the screen.
As shown in fig. 2, after acquiring the positions of the viewpoints pe of the user' S eyes on the screen, step S12 is performed.
And S12, confirming a contrast area with the viewpoint position as the center according to the viewpoint position.
Specifically, the contrast area may be set to a rectangular range or a circular range centered on the viewpoint. As shown in fig. 2, the contrast area Q is a rectangular range centered on the viewpoint Pe. Alternatively, the contrast area Q should be suitably small when set, which saves computational cost, and the contrast area Q conforms to the focus range of human eyes.
After the contrast area is confirmed, step S13 is performed.
S13, determining a final distance that the left-eye image and the right-eye image are simultaneously translated in different directions according to the pixel information in the contrast area when the left-eye image and the right-eye image are simultaneously translated in different directions.
Wherein the pixel information includes three primary color intensity values of the left-eye image pixel and the right-eye image pixel in the contrast region. When the left-eye image and the right-eye image are translated along different directions at the same time, the center point of the left-eye image and the center point of the right-eye image are coincident or the center point of the left-eye image is on the left of the center point of the right-eye image. And after the left eye image and the right eye image are translated in different directions by the final distance, the distance between the central point of the left eye image and the central point of the right eye image is smaller than or equal to the human eye distance.
That is, the center point of the left-eye image and the center point of the right-eye image are either in a coincident state, or the center point of the left-eye image is located on the left of the center point of the right-eye image, and the distance between the center points of the left-eye image and the right-eye image is smaller than or equal to the human eye distance.
The simultaneous translation of the left-eye image and the right-eye image in different directions includes a simultaneous outward translation of the left-eye image and the right-eye image and a simultaneous inward translation of the left-eye image and the right-eye image. The center points of the left and right eye images are coincided with the center of the screen when the viewpoint positions of the two eyes of the user on the screen are obtained for the first time, namely, the left eye image and the right eye image are completely overlapped at the initial position, and at the moment, the left eye image and the right eye image only need to be simultaneously translated outwards. However, in the initial position, if the center points of the left and right eye images do not coincide, both the left and right eye images need to be translated inward and outward.
Specifically, step S13: determining a final distance that the left-eye image and the right-eye image are simultaneously translated in different directions according to pixel information in the contrast area when the left-eye image and the right-eye image are simultaneously translated in different directions may include the following steps:
s131, acquiring pixel information in the contrast area when the left eye image and the right eye image are simultaneously translated along different directions by each unit distance.
And S132, calculating three primary color deviation values of the left-eye image pixel and the right-eye image pixel in the contrast area according to the pixel information.
Specifically, the three-primary-color deviation value is a sum of squares of differences of all pixel points in the contrast area with respect to three-primary-color values, and the lower the three-primary-color deviation value is, the higher the matching degree is. Wherein, the matching degree is the same degree of the images of the left eye image and the right eye image in the contrast area range. Since the focusing of the human eyes means that the left and right eye images are identical in the viewpoint position, only a person can see a clear image. That is, the higher the matching degree, the sharper the image can be seen.
The three primary color deviation value is obtained by calculating the following formula:
wherein b is a three primary color deviation value, c v1,i Intensity values of three primary colors c for the pixel i of the left eye image v1 in the contrast area Q; c. C v2,i Intensity values for the three primary colors c of the pixel i of the right eye image v2 in the contrast region Q; r is red, G is green, and B is blue.
And S133, when the left eye image and the right eye image are translated by n unit distances along different directions, determining that the calculation result of the three primary color deviation value is smaller than a threshold value, and the final distance is the sum of the n unit distances. Wherein n is a positive integer.
If the left-eye image and the right-eye image are completely overlapped at the initial position, at this time, the left-eye image and the right-eye image only need to be simultaneously translated outwards, for example, three primary color deviation values after the left-eye image and the right-eye image are translated outwards at the initial position by one unit distance are firstly calculated, then three primary color deviation values after the left-eye image and the right-eye image are translated outwards at the initial position by two unit distances are calculated until the three primary color deviation values after the left-eye image and the right-eye image are translated outwards at the initial position by n unit distances are smaller than a threshold value, and the sum of the n unit distances is smaller than or equal to half of the human eye distance.
If the left-eye image and the right-eye image are not completely overlapped at the initial position, at this time, the three primary color deviation value of the left-eye image and the right-eye image after the initial positions are shifted outward by one unit distance may be calculated first, and then the three primary color deviation value of the left-eye image and the right-eye image after the initial positions are shifted inward by one unit distance may be calculated. And then calculating three primary color deviation values of the left eye image and the right eye image after the left eye image and the right eye image are outwards translated for two unit distances at the initial positions, and then calculating three primary color deviation values of the left eye image and the right eye image after the left eye image and the right eye image are inwards translated for two unit distances at the initial positions until the three primary color deviation values of the left eye image and the right eye image after the left eye image and the right eye image are outwards translated for n unit distances at the initial positions are smaller than a threshold value or the three primary color deviation values of the left eye image and the right eye image after the left eye image and the right eye image are inwards translated for n unit distances at the initial positions are smaller than the threshold value, and the sum of the n unit distances is smaller than or equal to half of the human eye distance.
It should be noted that, in step S13 and step S131, the translation is mentioned, but the translation is mentioned in these steps only for calculating the three primary color deviation value, and the translation does not need to be presented on the screen in performing these steps, and only after calculating the final distance with the three primary color deviation value smaller than the threshold value, step S14 is performed to translate and present the left-eye image and the right-eye image on the screen.
S14, simultaneously translating the left-eye image and the right-eye image in different directions by the final distance.
For example, after the final distance that the left-eye image and the right-eye image need to be simultaneously shifted outward is confirmed, the three primary color deviation values of the left-eye image pixel and the right-eye image pixel in the contrast area can be smaller than a threshold value, and then the left-eye image and the right-eye image are shifted outward by the final distance.
As shown in fig. 2, after the final distance is confirmed, the left-eye image v1 and the right-eye image v2 are simultaneously shifted outward by the final distance starting from the positions of the left-eye image v1 and the right-eye image v2 at this time. Optionally, the left-eye image and the right-eye image are simultaneously translated in different directions by the final distance based on a speed at which the user's eyes converge the images.
Optionally, the naked eye 3D implementation method of the present application may further include the following steps:
s15, confirming the viewpoint position update during the step of simultaneously shifting the left-eye image and the right-eye image by the final distance in different directions.
S16, based on the updated viewpoint position, returning to the step of confirming the contrast area centered on the viewpoint position.
That is, the position of the viewpoint located on the screen is acquired in real time by the eye tracker. If the position of the viewpoint pe in fig. 2 is changed in the course of performing step S14, the panning is stopped, and the process returns to perform step S12 to confirm the contrast area centered on the changed viewpoint position from the changed viewpoint position.
Particularly, when the naked-eye 3D implementation method of the present application is applied to a 3D game, since the 3D game has model coordinates, the left and right eye images are different for modeling the game, but it is known where and what objects are in the left and right eye images, so that it is only necessary to move the same portion in the left and right images to the viewpoint at the viewpoint. Since the left and right displacements should be the same when moving, it is only necessary to find the same object parts at the left and right of the viewpoint, and the point with the same distance to the viewpoint is the point of the final distance of translation.
It should be noted that the reason why the human eye generates the 3D effect is that when the brain integrates different images obtained by the left and right eyes, the non-viewpoint portion has parallax, the brain feels the effect of displaying two different images in an overlapping manner, and when the viewpoint moves, the parallax and the focus point are constantly changed. On the other hand, since the left and right eyes obtain the same image, there is no parallax, and the depth relationship cannot be perceived from a physiological layer. The process of integrating images by the brain is the process of controlling the rotation of eyeballs and converging the sight centers of two eyes at the viewpoints. Because the eyeball is approximately a sphere, the acquired image is a spherical surface, the boundary range of different images acquired when the eyeball rotates is slightly different, and the position relation of an object in the different images is not changed. Therefore, the process of controlling the eyeball to rotate and converging the image at the viewpoint is completely equivalent to directly translating the two eye images to ensure that the viewpoint is superposed, and the image presented in the brain is also completely the same.
The application focuses on that the process of converging the left and right eyes to make the images of the two eyes coincide is completed by the electronic equipment. After the electronic equipment processes the images, the effect of overlapping the images of the two eyes is directly displayed on the screen, and the brain sees the images with the same effect as that seen in the real world through the screen.
When the viewpoint of the human eye changes on the screen, the eye tracker acquires viewpoint information in real time and transmits the viewpoint information to the electronic equipment. Because the refreshing of the human eye photosensitive cells needs a certain time, and the eye tracker is faster than the time, the electronic equipment can process images in real time and start to output the images before the human eye photosensitive cells sense the images which are automatically adjusted by human eyes.
Since the image processing is performed in advance in real time according to different viewpoints of users, the brain can obtain dynamic image effects with different parallaxes. When the viewpoint changes, the effect of eyeball change convergence is displayed on the screen in real time. Meanwhile, because objects in the left eye image and the right eye image at the non-viewpoint are not coincident, a fuzzy feeling can be generated, and the situation that the eyes see no focus at the non-viewpoint is consistent, so that the effect of eye adaptability adjustment can be generated.
Compared with the effect of actively changing focus in a video to generate the object relation far-near effect, the effect of the method is equivalent to that human eyes can randomly and autonomously find the far-near relation of the object in the image in the video playing process, and meanwhile, the method has the parallax effect.
The human eye visual cell sensitization refresh rate is only 15-60hz, and the sampling rate of the eye tracker can easily achieve 120hz or even higher. This is also what eye tracker users often feel, and have not seen by themselves, that the viewpoint fed back by the eye tracker has been displayed in advance to the real viewpoint. The eye tracker samples the time difference between the human eye cells and the sensed image, and the image processing and displaying process can be easily realized. This provides the technical basis for the implementation of the scheme of the present application.
The method is applied to photos and video sources shot by a 3D camera, 2D photos or 2D videos and 3D games through algorithm conversion of 3D film sources.
Based on the naked eye 3D implementation method shown in FIG. 1, the method has the following advantages:
first, this application is based on eye tracker, does not have extra requirement to the screen, also need not any wearing equipment. Any screen can realize naked eye 3D display effect by matching with an eye tracker, so that 3D display can be easily integrated into terminal equipment such as a computer or a mobile phone and the like of a user.
And secondly, the method has no extra requirement on the 3D film source, and can be realized only by common 3D film source or game modeling. The displayed object does not need to be subjected to omnibearing modeling or information acquisition, algorithm preprocessing is also not needed, and the existing 3D film source can be directly subjected to 3D display by using the scheme.
And thirdly, the requirement on computing power is not high, most common household computers or mobile phones can meet the requirement, and the method is easy to popularize quickly.
Compared with wearable equipment and a common grating light column naked eye display screen, the distance from human eyes to the common display screen is longer, the adjustment range of the eyeball focal length is smaller in the corresponding real situation, the conflict situation of convergence adjustment is greatly relieved, and eye fatigue and dizziness and headache are not easy to cause.
