[0023] Example one
[0024] figure 1 This is a schematic diagram of the naked eye 3D display calibration fixture provided in the first embodiment of the present invention. This embodiment can be applied to the case of 3D display module calibration. Such as figure 1 As shown, the naked eye 3D display correction fixture specifically includes:
[0025] The calibrated camera 110 is used to capture images displayed on the display screen that are interleaved according to the preset layout period and the preset layout period offset, the preset layout slope and the preset layout slope offset.
[0026] Specifically, the calibration camera 110 is placed on a sliding rail and can be slid relative to the sliding rail, and the optical axis of the calibration camera 110 is aligned with the center of the display screen. When the screen displays the images interwoven according to the design layout period and the preset layout period offset, the design layout slope and the preset layout slope offset...
