Image display method, method for manufacturing irregular screen having curved surface, and head-mounted display device

摘要

The present invention relates to an image display method and a head-mounted display device. The method comprises the following steps: capturing the original distorted image; Building a rectangular projection model having an aspect ratio equal to the aspect ratio of the captured image; Performing distortion correction processing on the rectangular projection model to obtain an irregular projection model; Building a spherical model according to the horizontal and vertical field of view of the camera, and superimposing the spherical model with the irregular projection model-corresponding center angles formed by the intersections of the irregular projection model and the spherical model in the horizontal and vertical directions, respectively. The horizontal and vertical field of view of the camera-; Connecting the lines radiating from the center of the spherical model to the four sides of the irregular projection model, and cutting through the spherical surface of the spherical model to obtain an irregular screen having a curved surface; Filling an original distorted image on a screen having a curved surface to complete an image rendering operation; And displaying the rendered image.
