Abstract

The invention relates to a method and an apparatus for displaying an image. The method comprises the following steps: acquiring an original deformed image; establishing a rectangular projection model which has same width-height proportion as a photographed picture; conducting anti-deformation processing on the rectangular projection model to obtain an abnormal projection model; based on the field angles in horizontal direction and vertical direction of a photographing camera, establishing a spherical model, bringing the abnormal projection model into inner connection to the spherical model, and spherical angles in corresponding directions constituted by the intersection points of the abnormal projection model and the spherical model in horizontal direction and vertical direction respectively becoming field angles in horizontal direction and vertical direction of the camera; emitting lines emit from the center of sphere being in connection to 4 edges of the abnormal projection model and obtaining the abnormal surface curtain by contouring the spherical surface of a spherical model; filling the abnormal surface curtain with the original deformed image to complete image rendering; displaying the rendered image. The method and the apparatus enable accurate and real-time displayed image.

Description

technical field [0001] The invention relates to the field of image display, in particular to an image display method and device, and a method and device for customizing a special-shaped curved surface curtain. Background technique [0002] A head-mounted display device is an important hardware device in virtual reality technology. It acquires the orientation of the user's head in real time and presents the scenery in this direction in front of the user's eyes. In this process, real-time and accuracy are the two main indicators that affect user immersion. Among them, real-time refers to rendering and displaying the image of the user's field of view in a very short period of time; accurate refers to: 1. The image seen by the user must match the prior knowledge, for example, the ground is flat, the wall is Straight; 2. The image distance of each pixel of the image is the same, so that when the user rotates the head, the image seen is on one surface, and there will be no image ...
