The invention discloses a 3D display device and method based on a composite rectangular multi-pinhole array. The 3D display device comprises a display screen and the composite rectangular multi-pinhole array, wherein the composite rectangular multi-pinhole array comprises a plurality of groups of one-dimensional rectangular pinholes and a plurality of groups of two-dimensional rectangular pinholes, each one-dimensional rectangular image element corresponds to a plurality of one-dimensional rectangular pinholes, a plurality of one-dimensional rectangular pinholes are horizontally symmetrical bytaking the center of the one-dimensional rectangular image element as the center, each two-dimensional rectangular image element corresponds to a plurality of two-dimensional rectangular pinholes, aplurality of two-dimensional rectangular pinholes are horizontally symmetrical by taking the center of the two-dimensional rectangular image element as the center, the one-dimensional rectangular image element reconstructs a plurality of one-dimensional 3D images through a plurality of corresponding one-dimensional rectangular pinholes, and the two-dimensional rectangular image element reconstructs a plurality of two-dimensional 3D images through a plurality of corresponding two-dimensional rectangular pinholes, and a plurality of one-dimensional 3D images and a plurality of two-dimensional 3Dimages are combined into a high-resolution and crosstalk-free 3D image in a viewing area.
Description
Technical field [0001] The present invention relates to 3D display. More specifically, the present invention relates to a 3D display device and method based on a composite rectangular multi-pinhole array. Background technique [0002] Compared with the visual aid / raster 3D display, the 3D display based on integrated imaging, referred to as the integrated imaging 3D display, has significant advantages such as no stereoscopic viewing fatigue and is a true 3D display. Compared with holographic 3D display, it has the advantages of relatively small amount of data, no need of coherent light source, and no harsh environmental requirements. It has become one of the cutting-edge 3D display methods in the world, and it is also the most promising kind of 3D TV. Naked true 3D display mode. However, the bottleneck problem of insufficient 3D resolution seriously affects the viewer's experience, thus restricting the wide application of integrated imaging 3D displays. In addition, traditional ...
