Description

  The present invention relates to the technical field of stereoscopic display, and more particularly to a calibration device for a stereoscopic display device that calibrates the mounting error of the optical device of the stereoscopic display device by measuring parameters of the stereoscopic display device.

  The imaging principle of the stereoscopic image display technique is as follows. Based on the parallax of both eyes of the observer, a parallax diagram having an image difference is detected by the left eye and the right eye of the observer, respectively, and a stereoscopic image is formed by the observer's brain based on the detected image difference.

  As shown in FIG. 1, the conventional stereoscopic display device 1 includes a spectroscopic device 11 and a display panel 12, and the spectroscopic device 11 is provided on the light emission side of the display panel 12. A left view and a right view having an image difference are provided by the display panel 12, but due to the spectral action of the spectroscopic device 11, the left view enters the left eye of the observer and the right view enters the right eye of the observer. Like that. The viewer's brain forms a stereoscopic image based on the sensed image difference.

  At the time of display, an accurate combination of the spectroscopic device 11 and the display panel 12 is required to avoid the crosstalk problem that the left view enters the observer's right eye and the right view enters the observer's left eye. However, since the mounting error between the spectroscopic device 11 and the display panel 12 is unavoidable during mounting, the spectroscopic device 11 cannot be accurately bonded to the display panel 12 as required by design, resulting in crosstalk. However, there are problems that the stereoscopic display effect is not excellent and that the requirement for stereoscopic imaging cannot be satisfied. If the stereoscopic display device is not processed before shipment, it directly affects the user's experience and further limits the development of the stereoscopic display technology.

By performing a cutting process on the first lead electrode, calibration is performed so that the initial states of the liquid crystal slits coincide with each other.

However, during the bonding, the mounting error between the liquid crystal slit optical grating and the display panel cannot be reduced, and the display effect of the stereoscopic display device after the bonding is not excellent.

  In the prior art, a parameter measurement system for a stereoscopic display device has been proposed. The actual value of the optical lattice parameter of the stereoscopic display device can be measured by detecting the projection image projected on the test plate when displaying the predetermined test screen of the stereoscopic display device and analyzing based on the detection result.

The image acquisition device 3 acquires the stereoscopic image and stores it in the horizontal shift amount calibration module 21. When the i-th horizontal shift amount calibration parameter is set to L _i and the horizontal shift amount detection step is set to b ₂ , L _i = L ₀ + (i−1) b ₂ (i ≧ 1). Before performing the image processing based on the i-times horizontal shift calibration parameters L _i, the horizontal shift amount calibration module 21, the i-times horizontal shift calibration parameters L _i determines whether the horizontal shift amount detection section . When the i-th horizontal shift amount calibration parameter _Li is not in the horizontal shift amount detection section, the above operation is stopped. If the i times the horizontal shift amount calibration parameters L _i is the horizontal shift amount detecting section, a horizontal shift amount calibration module 21, based on the i-times horizontal shift calibration parameters L _i, transmits the horizontal shift amount control signal . The stereoscopic display device 1 performs an alignment process on the display unit 121 based on the horizontal shift amount control signal, and displays a stereoscopic image after the alignment process. The image acquisition device 3 acquires the stereoscopic image and stores it in the horizontal shift amount calibration module 21. When the i-th horizontal shift amount calibration parameter _Li falls outside the horizontal shift amount detection section, the above operation is stopped. The horizontal shift amount calibration module 21 performs image processing on the stored stereoscopic image, and acquires a horizontal shift amount calibration parameter that satisfies a predetermined condition. The stereoscopic display device 1 performs an array process on the display unit 121 based on the horizontal shift amount calibration parameter when displaying a stereoscopic image, and eliminates the influence on the display effect due to the horizontal shift amount error. The acquisition of the horizontal shift amount calibration parameter does not require manual operation by the operator, reduces the labor intensity of the operator, and calibrates after the stereoscopic display device 1 is installed, so the reliability of the calibration result is high and the stereoscopic display is performed. Helps to improve the effect.

  As a further improvement of the above embodiment, as shown in FIGS. 1 and 2, the spectroscopic device 11 is tilted to the display panel 12 in order to avoid the periodic arrangement of the spectroscopic unit 111 and the display unit 121. The spectroscopic units 111 are arranged along the first direction, the display units 121 are arranged along the second direction, and the mounting error includes an angle error due to an angle between the first direction and the second direction. Further included. If the angle error is not calibrated, image crosstalk, particle feeling, etc. will occur, and the display effect of the stereoscopic display device 1 will be affected. The calibration parameter includes an angle calibration parameter for calibrating the angle error. The image acquisition device 3 acquires a stereoscopic image displayed on the stereoscopic display device 1. The control device 2 acquires an angle calibration parameter that satisfies a predetermined condition based on the stereoscopic image. When the user uses the stereoscopic display device 1, the stereoscopic display device 1 calibrates the angle error based on the angle calibration parameter, eliminates the influence of the angle error on the stereoscopic display, and improves the stereoscopic display effect.

Specifically, as shown in FIGS. 1 to 3, the control device 2 includes an angle calibration module 22. The angle calibration module 22 sets an angle detection section and an angle detection step based on design requirements and mounting accuracy. Specifically, to set the initial angle calibration parameters and A _0. Angle calibration module 22, based on the initial angular calibration parameters A _0, transmits the angle control signal. The stereoscopic display device 1 performs an alignment process on the display unit 121 based on the angle control signal, and displays a stereoscopic image after the alignment process. The image acquisition device 3 acquires the stereoscopic image and stores it in the angle calibration module 22. When the i-th angle calibration parameter is set as A _i and the angle detection step length is set as b ₁ , A _i = A ₀ + (i−1) b ₁ (i ≧ 1). Before performing image processing based on the i-th angle calibration parameter A _i , the angle calibration module 22 determines whether the i-th angle calibration parameter A _i is in the angle detection interval. When the i-th angle calibration parameter A _i is not in the angle detection section, the above operation is stopped. When the i-th angle calibration parameter A _i is in the angle detection section, the angle calibration module 22 transmits an angle control signal based on the i-th angle calibration parameter A _i . The stereoscopic display device 1 performs an alignment process on the display unit 121 based on the angle control signal, and displays a stereoscopic image after the alignment process. The image acquisition device 3 acquires the stereoscopic image and stores it in the angle calibration module 22. Outside from the i times the angle calibration parameters A _i is the angle detection section stops the operation. The angle calibration module 22 performs image processing on the stored stereoscopic image and acquires angle calibration parameters that satisfy a predetermined condition.

  As a further improvement of the above embodiment, as shown in FIGS. 1 to 3, the control device 2 further includes a region detection module 24 for detecting a display region in the stereoscopic display device 1. Since the image acquired by the image acquisition device 3 includes not only a stereoscopic image displayed on the stereoscopic display device 1 but also an external environment other than the display area, the accuracy of the angle calibration parameter and the horizontal shift amount calibration parameter by the external environment is improved. In order to avoid the influence of the above, it is necessary to detect a display area and perform an image related process in the display area before image processing. The control device 2 extracts image channel values in the display area, detects boundary points and boundary curves of the display area using edge detection, and further automatically detects the display area using the image area. To do. Further reduce the influence of the external environment on the detection results, and ensure the reliability of the calibration results.

  In the present embodiment, a stereoscopic image is stored in the stereoscopic display device 1 as shown in FIGS. By setting the display frequency of the stereoscopic image, the image acquisition device 3 acquires the stereoscopic image and transmits it to the control device 2. Of course, the control device 2 may control the display frequency of the stereoscopic display device 1 to realize the purpose of acquiring the stereoscopic image by the image acquisition device 3. A stereoscopic image can be displayed in various types, and the operation is convenient, and the use range of the calibration device of the stereoscopic display device according to the present embodiment is expanded.

  During calibration, the detection time can be shortened, and the detection section can be set according to the mounting error. If the calibration parameter cannot be acquired, a larger value is taken for the detected stride, the detection is accelerated, and the calibration parameter that satisfies the predetermined condition is acquired as soon as possible. When the calibration parameters satisfying the predetermined condition are acquired, the detected stride is returned to a normal value or a smaller value is obtained, and many calibration parameters satisfying the predetermined condition are acquired. If calibration parameters are not acquired again, the detection is stopped, the detection time is shortened, and the detection efficiency of the stereoscopic display device 1 is improved. Alternatively, the binarization process is performed for each detection interval, and the detection is continued when the calibration parameter is acquired within the detection interval. However, when the calibration parameter cannot be acquired within the detection interval, the detection interval is skipped.

The replacement operation is simple and easy to implement. Of course, the relative position between the camera 32 and the stereoscopic display device 1 may be adjustable. The relative position between the camera 32 and the stereoscopic display device 1 is adjusted in accordance with the acquired viewing angle of the camera 32. A stereoscopic image can also be acquired during image acquisition.

  In order to simulate the usage environment of the stereoscopic display device 1, the camera 32 can be regarded as a human eye. Therefore, the camera 32 is attached at a position corresponding to the position of the human eye.
