Abstract

The present invention discloses an image rendering method and a system. The method comprises an acquisition step for acquiring the image frames of a to-be-rendered image, wherein the image frames comprise a plurality of key frames and a plurality of reference frames, one key frame corresponds to a plurality of reference frames, the key frames represent the particular scene optical information, and the reference frames represent the depth information of key frames; a processing step for acquiring two motion fields according to the plurality of key frames and the plurality of reference frames, wherein the two motion fields comprise a motion field between key frames and reference frames and a motion field between different key frames; and a rendering step for obtaining a rendered image through rendering the plurality of processed key frames. According to the invention, based on two motion fields different in scale, the 360-degree panoramic image rendering effect is realized.

Description

Technical field [0001] The invention relates to the field of computer multimedia technology, in particular to an image rendering method and system. Background technique [0002] With the rapid development of head-mounted display technology, virtual reality (VR) technology has become increasingly mature. Although more and more head-mounted display devices have come out in recent years, the content of virtual reality is still greatly restricted by technical bottlenecks. In order to achieve more realistic VR content in real scenes, a lot of manual and complicated 3D scene reconstruction work is required. [0003] At present, the main methods for generating VR content of real scenes are panoramas and binocular stereo panoramas. The generation of the panoramic image is achieved by collaging multiple pictures taken by ordinary cameras. However, due to the inherent image properties of the panorama, it does not have the depth information of the scene. In other words, the panorama only ...
