The display device 12 must be accurately matched between the spectroscopic device 11 and the display panel 12 in order to avoid the occurrence of crosstalk in which the left image enters the right eye of the viewer and the right image enters the viewer's left eye. However, at the time of assembly, an assembly error between the spectroscopic device 11 and the display panel 12 can not be avoided, and the spectroscopic device 11 can not be brought into close contact with the display panel 12 exactly according to the design demand, The stereoscopic display effect is not good and even the requirement for stereoscopic image formation can not be satisfied.

The parallel movement amount correcting module 21 performs image processing on the stored stereoscopic image to obtain a parallel movement amount calibration parameter satisfying a predetermined condition. When displaying the stereoscopic image, the stereoscopic displaying apparatus 1 advances the arrangement process with respect to the display unit 121 based on the parallel movement amount calibration parameter to eliminate the influence of the parallel movement amount error on the display effect. The acquisition of the parallel movement calibration parameter does not require the manual operation of the operator, thereby reducing the work intensity of the operator. Further, after the assembling of the stereoscopic displaying apparatus 1 is completed, the calibration result is corrected again, so that the reliability of the calibration result is high and it is advantageous to enhance the stereoscopic displaying effect.

The stereoscopic display device 1 shown in Fig. Since the image acquired by the image acquiring device 3 includes not only the stereoscopic image displayed by the stereoscopic displaying device 1 but also the external environment outside the display area, the external environment influences the accuracy of the angle calibration parameter and the parallel movement calibration parameter In order to prevent this, it is necessary to detect the display area before the image processing and to carry out the related processing on the image in the display area. The control device 2 can detect the boundary points and the boundary curves of the display area by using the edge detection after extracting the image channel values in the display area, and by combining the image areas again, the display area can be automatically detected. This further reduces the influence of the external environment on the detection result to ensure the reliability of the calibration result.

In the calibration process, the detection interval is set based on the assembly error to shorten the detection time. When the calibration parameter is not obtained, the detection step length is increased to accelerate the detection, so that the calibration parameter satisfying the predetermined condition can be obtained as quickly as possible. When a calibration parameter satisfying a predetermined condition is obtained, it is possible to obtain more calibration parameters satisfying a predetermined condition by restoring the detection step length to normal or setting it to be small. When the calibration parameter can not be acquired again, the detection can be stopped and the detection time can be shortened, thereby improving the detection efficiency of the stereoscopic display apparatus 1. [ Alternatively, the binarization processing may be performed on the detection interval, and the detection interval may be continuously detected when the calibration parameter is obtained.
