Abstract

The invention provides a 4D video rendering method comprising steps of camera selection, visible patch calculation, visible patch texture extraction, fusion weight map calculation, edge blending, andsynthesis rendering. With the method, texture chartlet rendering is carried out on a three-dimensional model of a main scene body obtained by 4D capturing from shot multi-camera image data efficientlywith high quality, so that the three-dimensional model is able to represent a 4D video effect vividly.

Description

technical field [0001] The present invention relates to the field of multimedia technology, in particular to a 4D video rendering method. Background technique [0002] 4D video includes four dimensions: three-dimensional space and one-dimensional time. 4D holographic capture refers to a high-quality, realistic 4D virtual reproduction method for static or dynamic scenes in real space. Existing 3D movies usually form a left and right eye imaging view on the viewing angle of the user, thereby forming a 3D stereoscopic viewing experience from the user's viewing angle. In fact, it only obtains 2.5-dimensional depth information and does not restore it. Get a true 3D view of your subject. [0003] High-quality real-time 4D video has many potential applications in virtual reality (VR), augmented reality (AR) or mixed reality (MR). For example, it can be used for character creation in 3D games and 3D animation. In the field of clothing, 4D video can realize scenes such as virtual ...
