Description

Technical Field

[0002] In the current naked-eye 3D display technology, one solution is to achieve the 3D effect by attaching a special cylindrical lens on the display screen. When the light emitted by the display screen passes through the lens, it will be guided to different angles, so that the left and right eyes receive different images, producing a 3D stereoscopic effect. However, in actual operation, there will be a slight deviation when attaching the cylindrical lens, resulting in the 3D effect not achieving the expected effect. In order to correct the deviation caused by attaching the cylindrical lens, the relevant parameters of the 3D display screen can be corrected to compensate for this deviation.

[0003] The existing method of verifying the relevant parameters on the 3D display screen is to verify it manually, so that the human eye is in the middle of the 3D display screen to observe the proportion of the single-viewpoint full white area displayed on the 3D display screen. The closer the picture is to full white, the better the 3D effect is considered. However, when verifying the parameters manually, it is difficult for the human eye to keep the position of the 3D display screen unchanged, and it is also difficult for the human eye to accurately evaluate the proportion of the white area of ​​the 3D display screen.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Please refer to Figure 1 , an embodiment of the present invention provides a display screen parameter verification method, comprising:

[0049] Step 11: obtaining the correction parameters to be verified of the target 3D display screen, and controlling the target 3D display screen to display a 3D verification picture rendered according to the correction parameters to be verified;

[0050] In some embodiments, the target 3D display screen is a 3D display screen with a cylindrical lens attached to the display screen; the correction parameters to be verified may include: the number of lines, the tilt angle and the offset for correcting the attachment deviation of the cylindrical lens.

[0051] In some embodiments, the step of obtaining the correction parameters to be verified of the target 3D display screen includes:

[0052] Obtaining the QR code of the target 3D display screen;

[0053] The two-dimensional code is parsed to obtain the correction parameter to be verified.

[0054] In some embodiments, the QR code of the target 3D display screen can be scanned by a barcode scanner.

[0055] In some embodiments, the display screen parameters can be verified by using the main screen and the secondary screen. In this embodiment, the display screen parameter verification device may include: a main screen and a secondary screen (the secondary screen is the target 3D display screen). The barcode scanner transmits the scanned information to the display screen parameter verification device. The display screen parameter verification device parses the QR code to obtain the correction parameters to be verified associated with the QR code, and displays them on the main screen. Please refer to Figure 2 , a parameter interface is displayed on the main screen, the parameter interface includes multiple input boxes, if the parameter format parsed by the display screen parameter verification device is correct (for example, the format is: 12.098, 0.2003, 3001.1), the parsed parameters are separated into three parts according to commas, and 12.098 is filled into the line number input box, 0.2003 is filled into the tilt angle input box, and 3001.1 is filled into the offset input box. Then, the display screen parameter verification device uses these three parameters to interweave and render a 3D verification picture in real time, and transmits the 3D verification picture to the secondary screen for display.

[0056] Step 12: Acquire a target image of the 3D verification screen captured by an external camera at a preset first position;

[0057] In some embodiments, the display screen parameter verification device can also be connected to the external camera to control the main screen to display the target image of the 3D verification screen captured by the external camera in real time, such as Figure 3 As shown, when the external camera is correctly connected, the display screen parameter verification device displays the acquired target image in real time.

[0058] Please refer to Figure 4 , using cameras instead of human eyes can accurately fix the device at a certain position and keep it motionless, thus effectively improving the accuracy of verification.

[0059] Step 13: Determine whether the target image meets the preset verification conditions. If the target image meets the preset verification conditions, determine that the correction parameters to be verified have passed the verification; if the target image does not meet the preset verification conditions, determine that the correction parameters to be verified have not passed the verification.

[0060] In some embodiments, optionally, the first position is determined according to a specified viewpoint interval in the target 3D display screen, wherein each target 3D display screen includes at least one viewpoint interval, and the 3D verification image is rendered according to the specified viewpoint interval.

[0061] In the embodiment of the present invention, the corresponding 3D verification picture is obtained by selecting a viewpoint interval for rendering, and specifically setting the viewpoint interval to display all white, and the viewpoint interval to display all black. Taking the 3D verification picture having 24 viewpoint intervals as an example, i.e., 0-24, a complete 3D picture needs to select the viewpoint interval of 0-24. If the viewpoint interval of 11.5-12.5 is selected, the 3D verification picture is displayed in full white in the viewpoint interval of 11.5-12.5, and is displayed in full black outside the viewpoint interval. If the viewpoint interval of 0-12 is selected, the 3D verification picture has half white and half black. Figure 5 If you select the viewpoint interval of 0-24, the 3D verification screen will be completely white. Figure 6 As shown; if the viewpoint interval of 11.5-12.5 is selected, the 3D verification screen will only have 1 / 24 of the white screen, such as Figure 7 As shown, the 3D calibration screen in the 11.5-12.5 viewpoint range is completely white.

[0062] In the embodiment of the present invention, optionally, the distance between the external camera at the first position and the target 3D display screen is less than or equal to a first distance threshold, and the projection of the external camera on the target 3D display screen is located in the middle interval of the specified viewpoint interval of the target 3D display screen.

[0063] In the embodiment of the present invention, the effect of 3D display is verified by watching the single viewpoint 11.5-12.5 picture at the exact center of the target 3D display screen. If all white can be seen on the target 3D display screen, it means that the parameters of the target 3D display screen are correct. If the white picture seen is mixed with gray or black, it means that the 3D effect of the target 3D display screen after adopting this set of parameters is not so good. The closer to all white, the better the 3D effect. A camera is used to automatically take pictures, process and analyze the pictures, set a threshold, calculate the proportion of white pixels and compare it with the threshold, and judge whether the parameters pass.

[0064] In an embodiment of the present invention, after obtaining the target image of the 3D verification screen captured by the external camera at a preset first position, the method may also include: performing image processing on the target image, such as cropping the image, and retaining only the screen content displayed on the target 3D display screen as the target image.

[0065] In the embodiment of the present invention, optionally,

[0066] Determining whether the target image meets a preset verification condition includes:

[0067] The RGB pixel values ​​of the target image are converted into grayscale values, and it is determined whether the grayscale value of each pixel in the target image meets a preset grayscale value threshold, and the proportion of the number of pixels that meet the preset grayscale value threshold in the total number of pixels in the target image meets a preset pixel threshold. If the preset pixel threshold is met, it is determined that the preset inspection condition is met.

[0068] In an embodiment of the present invention, the target image is analyzed to determine whether the grayscale value of each pixel in the target image meets a preset grayscale value threshold. If so, it is identified as a white pixel, thereby determining the proportion of white pixels in the target image. If it reaches a certain threshold, it is determined that the parameters of the target 3D display screen have passed.

[0069] In some embodiments, the tool adjustment interface on the main screen may give the following conclusions: Device SN: xxx, parameters passed verification; or Device SN: xxx, parameters failed verification, and the conclusion may be saved locally in real time, for example, in a local txt text, for subsequent viewing.

[0070] In some embodiments, the statistical method for calculating the proportion of white pixels in the target image includes: first converting the RGB values ​​of the pixels of the target image into grayscale values, then determining whether the grayscale value of each pixel in the target image is greater than a certain threshold, and if it is greater than or equal to the threshold, it is used as a target pixel, and finally dividing the number of target pixels counted by the total number of pixels in the image to obtain the proportion; then setting a threshold for the proportion, for example, 95%, and if the proportion is greater than or equal to the set threshold of 95%, it is considered that the parameter verification of this 3D display screen has passed, and if it is less than the threshold of 95%, it is considered that the parameter verification has failed; wherein, the grayscale value calculation formula is: Grayscale Value = 0.2989×R+0.5870×G+0.1140×B.

[0071] Please refer to Figure 8 In the embodiment of the present invention, the overall process of the display screen parameter verification method includes:

[0072] The barcode scanner transmits the scanned information to the display screen parameter verification device, and the display screen parameter verification device parses the QR code to obtain the correction parameters to be verified associated with the QR code, and displays them on the main screen;

[0073] The 3D verification picture is rendered in real time by interweaving the correction parameters to be verified, wherein the target image of the 3D verification picture is captured by the external camera at a preset first position; the first position is determined according to a specified viewpoint interval in the target 3D display screen, wherein each target 3D display screen includes at least one viewpoint interval, the 3D verification picture is rendered according to the viewpoint interval, the viewpoint interval is optional, the 3D verification picture within the viewpoint interval is displayed in white, and the 3D verification picture outside the viewpoint interval is displayed in black;

[0074] Taking an initial image of the 3D verification screen at a preset first position by an external camera and saving the image;

[0075] Performing image processing on the target image, such as cropping the image, and retaining only the image content displayed on the target 3D display screen as the target image;

[0076] Performing image processing and analysis on the target image;

[0077] Automatically judge whether the parameters are passed. If they reach a certain threshold, the parameters of the target 3D display screen are considered passed, and the system tool adjustment interface gives the conclusion: device SN: xxx, parameter pass; or device SN: xxx, parameter fail;

[0078] The conclusion is saved in real time to the local txt text, which is convenient for checking whether the parameters of which 3D screen pass or fail later.

[0079] In an embodiment of the present invention, the correction parameters to be verified of the target 3D display screen are obtained, and the target 3D display screen is controlled to display a 3D verification picture rendered according to the correction parameters to be verified; the target image of the 3D verification picture taken by an external camera at a pre-set first position is obtained; it is determined whether the target image meets the preset verification conditions, and if the target image meets the preset verification conditions, it is determined that the correction parameters to be verified have passed the verification; if the proportion of white pixel values ​​in the target image does not meet the preset pixel threshold, it is determined that the correction parameters to be verified have not passed the verification. By setting up an external camera to capture the target image of the 3D verification picture and analyzing the target image to verify the parameters of the 3D display screen, instead of verifying the parameters of the 3D display screen by viewing with the human eye, the accuracy of the verification can be effectively improved.
