The invention discloses a high-resolution light field display method based on frequency domain displacement. The method comprises 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 moving image elements of all sub-images of the element array image from high frequency to low frequency; S3, carrying out image preprocessing on the image after frequency shift, then carrying out frequency spectrum separation, and carrying out frequency spectrum registration on the image after frequency spectrum separation to obtain a high-frequency component and a low-frequency component; S4, performing frequency spectrum fusion and image reconstruction on the image after frequency spectrum registration; S5, refreshing the high-resolution element array image on the display panel at a high speed; and S6, further converging through a micro-lens array, and enabling the light to enter a holographic scattering screen to realize three-dimensional display. According to the method, the defect that in the prior art, the sampling rate of a micro-lens array is too low is overcome, so that a display result with higher resolution can be obtained, the calculation complexity is reduced, and the method 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 ...
