The invention discloses a high-resolution light field display method based on frequency domain displacement, comprising the following steps: S1, constructing an element array image of a virtual three-dimensional object through virtual three-dimensional software; S2, constructing a frequency domain translation vector, and converting the element array The image elements of all sub-images of the image are moved from high frequency to low frequency; S3, image preprocessing is performed on the image after frequency shift, and then spectrum separation is performed, and spectrum registration is performed on the image after spectrum separation to obtain high frequency components and Low-frequency components; S4, performing spectrum fusion and image reconstruction on the images after spectrum registration; S5, refreshing the high-resolution element array images on the display panel at high speed; S6, further converging through the microlens array, incident on the holographic scattering 3D display on the screen. The invention overcomes the defect that the sampling rate of the microlens array is too low in the prior art, so that display results with higher resolution can be obtained, the computational complexity is reduced, and the invention has better application prospects.
Description
technical field [0001] The invention relates to the field of three-dimensional stereoscopic display, in particular to a high-resolution light field display method and device based on frequency domain displacement. Background technique [0002] The real world around humans is three-dimensional, and we need to use three-dimensional information to fully understand and accurately judge things in scenes such as life and work. However, traditional flat-panel displays can only display two-dimensional plane information to viewers, losing depth information, and cannot meet the requirements of various industries for the visualization of three-dimensional data and depth information. Three-dimensional stereoscopic display technology can display three-dimensional images containing real scene depth information for audiences. In recent years, this technology has attracted extensive attention from researchers at home and abroad. Autostereoscopic display technology includes multi-viewpoint ...
