Description

Technical Field

[0001] This invention relates to the field of naked-eye 3D technology, and in particular to a naked-eye 3D effect testing device and testing method. Background Technology

[0002] With the rapid development of stereoscopic display technology, the demand for stereoscopic display devices is also increasing. Among the many technologies that realize three-dimensional stereoscopic display, naked stereoscopic display is highly favored in the field of three-dimensional stereoscopic display because it does not require viewers to wear glasses.

[0003] Currently, the main method for achieving naked-eye stereoscopic display technology is to place a grating in front of or behind the display panel. This horizontally divides the display panel's pixel units into odd-numbered columns and even-numbered columns, providing the viewer's left and right eyes with two different images. The parallax effect between the left and right eye images creates depth, resulting in a stereoscopic display effect. Gratings come in two types: obstruction-type and beam-splitting-type. Obstruction-type gratings are further divided into black-and-white parallax barrier gratings and liquid crystal slit gratings, while beam-splitting gratings include lenticular physical lenses and switchable liquid crystal lenses. Switchable liquid crystal lenses are further divided into three types: switchable resin-type lenticular liquid crystal lenses, switchable polarized liquid crystal lenses, and switchable electrode-type liquid crystal lenses. Currently, the most widely used type is the fixed lenticular physical lens.

[0004] Figure 1 The diagram shows the optical design and implementation principle of the naked-eye 3D product. The pitch of a cylindrical grating corresponds to multiple sub-pixels. The light emitted by the sub-pixels is refracted by the cylindrical grating and enters the left and right eyes of the person respectively. Then, the brain fuses the light to perceive the stereoscopic effect.

[0005] Current methods for judging the quality of naked-eye 3D products involve displaying an interwoven red-green image on a screen, with the emitted light penetrating the naked-eye 3D optical structure and then being perceived by the human eye. Figure 2 As shown, the left viewpoint image displays a red image, and the right viewpoint image displays a green image. After being split by the naked-eye 3D optical structure, the light enters the left and right eyes respectively. The human eye judges the quality of the red and green images, and thus judges the quality of the naked-eye 3D effect. However, since the human eye's judgment lacks a quantifiable mechanism, and also varies from person to person (e.g., the interpupillary distance between different people is different), the judgment results will also vary, making it impossible to obtain an accurate judgment result.

[0006] On the other hand, based on theoretical principles and actual test results, when the naked-eye 3D optical structure corresponds one-to-one with the pixel structure within the display device, the optimal position for stereoscopic display is at the center of the display device screen. However, when there is a slight deviation between the two, the optimal viewing position will also shift, such as... Figure 3As shown, the existing solution still relies on the human eye to objectively judge the offset of the best viewing position, which cannot accurately and quantitatively determine the specific value.

[0044] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0045] This invention provides a naked-eye 3D effect detection device, such as... Figures 4-5As shown, the naked-eye 3D effect testing device may include a device bracket 100, a sliding rod 300, and a detector 400. The device bracket 100 is used to fix the display device 200 and the naked-eye 3D optical component 500 to be tested, which is disposed on the surface of the display device 200. In this embodiment, the display device 200 can be a mobile phone, tablet, laptop, monitor, television, advertising machine, video wall, or other type of display. The size of the device bracket 100 can be scaled down or enlarged according to the size of the product under test, thus satisfying the testing requirements of different types of naked-eye 3D display devices 200. The naked-eye 3D optical component 500 to be tested can be a naked-eye 3D optical structure or a product related to a naked-eye 3D optical structure.

[0046] The sliding rod 300 can slide relative to the equipment bracket 100 along a first direction, wherein the first direction can be a vertical direction. For example... Figure 4 As shown, the equipment bracket 100 includes a bracket base 110 and a support member 120 fixedly connected to the bracket base 110. The support member 120 extends from the support base 110 along a first direction. A sliding rod 300 is slidably connected to the support member 120, meaning the sliding rod 300 can slide back and forth relative to the support member 120 in the first direction. In other words, the equipment bracket 100 in this embodiment can be a gantry frame with a base, mainly used to fix various components in a naked-eye 3D effect testing device. In practical applications, the support member 120 can be a double vertical support rod, and the sliding rod 300 can be a horizontally adjustable support rod. Furthermore, the sliding rod 300 can be a single-axis supported support rod, and the support member 120 can be equipped with a threaded lifting rod. The sliding rod 300 can be raised and lowered by cranking a handle, or an electric motor can be used to achieve the raising and lowering of the sliding rod 300. Of course, the support member 120 may also be provided with a slide rail or slide groove for the sliding rod 300 to slide up and down. The sliding rod 300 can slide up and down along the slide rail or slide groove. In addition, the support member 120 may also be provided with a fixing member for fixing the sliding rod 300, so as to fix the sliding rod 300 when it slides to a set position. In practical applications, the fixing member may be a buckle, a lock, or a component that can fix the sliding rod 300 to the support member 120. This embodiment does not limit this.

[0047] like Figure 4 As shown, the first direction can be the vertical direction. The sliding rod 300 slides back and forth on the support 120 in the vertical direction. The sliding rod 300 moves up and down mainly because the product design distance is different. When testing different products, the height is adjusted.

[0048] At least two image acquisition units 310 are provided on the sliding rod 300. The image acquisition units 310 are positioned opposite the naked-eye 3D optical device 500 under test and are used to acquire images displayed by the naked-eye 3D optical device 500. The image acquisition unit 310 can be a camera, with its lens focused on the naked-eye 3D optical device 500 under test. A detector 400 is connected to the image acquisition unit 310 to detect the naked-eye 3D effect of the naked-eye 3D optical device 500 under test based on the images acquired by the image acquisition unit 310. Optionally, the detector 400 can be a computer processing device such as a tablet computer, laptop, or desktop computer. The detector 400 can be connected to the image acquisition unit 310 via a data cable to receive the images acquired by the image acquisition unit 310 and analyze these images to detect the naked-eye 3D effect of the naked-eye 3D optical device 500 under test.

[0049] The display device 200 has a display panel, and the image acquisition device 310 is focused on the display center corresponding to the display panel. The image acquisition device 310 is disposed opposite to the naked-eye 3D optical component 500 to be tested in the first direction, and can rotate relative to the sliding rod 300 in the first direction. The display panel is disposed parallel to a second direction, which is perpendicular to the first direction. In practical applications, the first direction can be a vertical direction, and the second direction can be a horizontal direction. It is understood that when installing the image acquisition device 310, it is necessary to ensure that the lens of the image acquisition device 310 is in a vertical plane and can rotate a certain angle in the vertical plane to focus on the display center position of the display device 200.

[0050] Optionally, a rotating stage 130 is provided on the device support 100, and the rotating stage 130 is connected to the device support 100 through a rotating component 140; the display device 200, which is provided with the naked-eye 3D optical component 500 to be tested, is fixedly disposed on the rotating stage 130 so as to rotate with the rotating stage 130.

[0051] like Figure 4 As shown, the rotating platform 130 is mounted on the support base 110. Specifically, the rotating platform 130 is rotatably connected to the support base 110 via a rotating component 140. The rotating platform 130 is angle-adjustable and can be fixed at the adjusted angle by an angle locking lock 143, which also secures the display device 200. The rotating platform 130 can be rotated manually or by an electric motor. An angle gauge is fixedly mounted on the rotating platform 130 to detect its rotation angle. Generally, the surface of the rotating platform 130 is on a horizontal plane, and the angle gauge on the rotating platform 130 can be a horizontal angle gauge. The reading displayed by the horizontal angle gauge indicates that the rotating platform 130 is in a horizontal position.

[0052] The rotating component 140 may include a rotating shaft 141, a rotating plate, and a bearing seat 142. The rotating plate may be a flat plate, which is fixedly mounted on the rotating shaft 141. The rotating shaft 141 is fixedly connected to the support base 110 via the bearing seat 142. An angle fixing lock 143 is provided on the rotating shaft 141 to fix the rotating platform 130 after the rotating platform 130 drives the display device 200 to rotate to a fixed angle. Optionally, a rotating handle 144 may be provided at one end of the rotating shaft 141 to control the rotating plate to rotate, thereby driving the display device 200 and the corresponding naked-eye 3D optical component 500 under test on the rotating platform to rotate. Alternatively, the rotating shaft 141 may be connected to an electric motor, which drives the rotating shaft 141 to rotate. The rotation direction and rotation angle of the rotating platform 130 can be set according to actual application requirements, and this embodiment of the invention does not limit this.

[0053] The display device 200 is used to display a video file containing a mixture of a first hue and a second hue. Two image acquisition units 310 can be mounted on the sliding lever 300, including a first image acquisition unit 311 and a second image acquisition unit 312. The first image acquisition unit 311 and the second image acquisition unit 312 are respectively used to acquire the first hue image and the second hue image displayed by the display device 200 via the naked-eye 3D optical component 500 under test. Optionally, the display device 200 can display red-green video, and the first image acquisition unit 311 and the second image acquisition unit 312 respectively acquire the red image and green image corresponding to the red video.

[0054] The detector 400 is equipped with a detection program. The detector 400 uses this program to detect the naked-eye 3D effect of the naked-eye 3D optical device 500 under test based on the images acquired by the image acquisition unit 310. For example, the detection program can select multiple sampling points based on a first image acquired by the first image acquisition unit 311 and a second image acquired by the second image acquisition unit. The program compares the image color corresponding to each sampling point with a preset standard color, and obtains the detection result of the naked-eye 3D display effect of the naked-eye 3D optical device 500 under test based on the comparison result. In other words, each image acquisition unit 310 can acquire images displayed by the display device 200 via the naked-eye 3D optical device 500 under test. For any image acquired by any image acquisition unit 310, multiple (e.g., 25) sampling points can be selected from the image. For each sampling point, the color corresponding to that sampling point can be compared with a standard color, and the color difference percentage of each sampling point can be obtained. Target sampling points with a color difference percentage less than a set value are selected from the multiple sampling points, and the number of target sampling points is counted. When the number of target sampling points corresponding to each of the two image acquisition devices 310 simultaneously meets the requirement of not less than 80% of the total number of sampling points, the test result of the naked-eye 3D effect of the naked-eye 3D optical component 500 under test is deemed qualified.

[0055] This invention also provides a method for detecting naked-eye 3D effects using the naked-eye 3D effect detection device described in the above embodiments, such as... Figure 6 As shown, the method provided in this embodiment may include:

[0056] S1, the detection program set in the detector 400 is started to display the first image captured by the first image acquisition unit 311 and the second image captured by the second image acquisition unit 312 based on the detection program. The first image acquisition unit 311 and the second image acquisition unit 312 are used to acquire the video file displayed by the display device 200 via the naked-eye 3D optical component 500 under test. In practical applications, it is necessary to first confirm the stability of the equipment of the image acquisition unit 310, the display device 200 and the detector 400 after powering on, confirm that the up and down moving bar, the rotating stage 130, etc. can be used normally, open the test software, and the software interface should display the image captured by the camera normally. For example, prepare the naked-eye 3D optical component 500 under test (such as a naked-eye 3D film) and the corresponding model of mobile phone (i.e., the display device 200), open the mobile phone application, and display the red and green video.

[0057] Configure the detection program in the detector 400 (such as a computer), select two cameras respectively, set the detection area to the entire display area, after the detection area is set, 25 sampling points will be displayed, and then set the standard reference color (red or green).

[0058] S2, select multiple sampling points based on the first image and the second image respectively. Specifically, the detection program in the detector 400 (such as a computer) will take 25 sampling points from each of the two cameras by pressing the shutter button "F6" or by using an external USB foot switch.

[0059] S3, compare the image color corresponding to the sampling point with the preset standard color, and obtain the detection result of the naked-eye 3D effect of the naked-eye 3D optical component 500 under test based on the comparison result.

[0060] Compare the above sampling points with the standard reference color. When the number of target sampling points with a color difference value of less than 10% between the sampling points and the standard color is greater than 80%, that is, when the number of target sampling points is greater than or equal to 20, the naked-eye 3D optical component to be tested is determined to be a qualified product.

[0061] Optionally, before step S2 above, the angle of the display device 200 may be adjusted so that the first image acquired by the first image acquisition unit 311 and the second image acquired by the second image acquisition unit are respectively images of the first hue and the second hue; wherein, the display device 200 is used to display a video file mixed with the first hue and the second hue. The display device 200 is used to display red-green video. That is, the mobile phone needs to be placed on the rotating platform 130, and a horizontal angle meter is placed on the rotating platform 130 at the same time. The reading displayed by the horizontal angle meter indicates that the rotating platform 130 is in a horizontal position. Make the camera vertically downward, rotate the camera in the vertical plane to focus on the center position of the mobile phone display, and at the same time ensure that the long side of the mobile phone display screen is parallel to the boundary of the display screen. Fix the mobile phone and camera, with a distance of 65mm between the two lenses. The distance between the lens and the surface of the mobile phone is adjusted according to the design requirements. Adjust the height of the up and down moving bar.

[0062] If the images captured by the two lenses do not show a completely red or green display, or if one side shows a completely red or green display while the other side does not, adjust the angle of the rotating platform 130 to make it horizontal. On this basis, the angle of the rotating platform 130 can be finely adjusted to ensure that the images captured by the two cameras are one completely red and the other completely green.

[0063] After the naked-eye 3D optical component 500 is tested, it is removed, and the next product is tested or the test is terminated.

[0064] In practical applications, the criteria for judging the quality of a product include two parts: first, the percentage difference between the value of each point and the standard color is less than or equal to 10%; second, the proportion of all points with a difference of less than or equal to 10% to the total number of points is greater than or equal to 80%. Further, the percentage difference can be 1% to 30%, preferably 5% to 15%, and the proportion of points can be 70% to 100%, preferably 80% to 90%. Even further, the total number of test points can be 5 to 100, preferably 20 to 50.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that within the spirit and principles of the present invention, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the corresponding technical solutions to depart from the protection scope of the present invention.
