Embodiment Construction

[0016] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0017] see Figure 1-2 , a method for realizing 3D scene recording and broadcasting based on a light field camera, the specific steps are as follows:

[0018] (1) The light field information is collected simultaneously by multi-angle and multiple light field cameras, and the main control computer collects these information and converts the light field information into a depth point cloud with RGB colors;

[0019] (2) The main control computer synchronously fuses and reconstructs the data of multiple light field cameras into a dynamic 3D scene data, and these data are scenes depicted in the form of point clouds

[0020] (3) The main control computer performs grid optimization on the point cloud data into 3D model and texture information;

[0021] (4) The main control computer transmits the 3D model data to the user client;

[0022] (5) The user c...

Abstract

The invention discloses an optical-field-camera-based realization method for three-dimensional scene recording and broadcasting. A plurality of optical-field cameras with multiple angles collect optical field information simultaneously; a main control computer collects the information and converts the optical field information into depth point clouds with RGB colors; the main control computer carries out synchronous fusion on data of the multiple optical-field cameras to reconstruct dynamic 3D scene data, wherein the data are scenes described in a point cloud mode; the main control computer carries out mesh optimization on the point cloud data to obtain a 3D model and chartlet information; the main control computer transmits the 3D model data to a user client; and user client software constructs a virtual 3D scene based on the data and carries out rendering. According to the invention, the main control computer collects the information and converts the optical field information into the depth point cloud data with the RGB colors to realize 3D scene reconstruction and then the virtual camera carries out 3D scene rendering again. Therefore, free changing at any angle is realized; and a rendering distance and an illumination direction can be adjusted.

Description

technical field [0001] The invention relates to a method for realizing three-dimensional scene recording and broadcasting, in particular to a method for realizing three-dimensional scene recording and broadcasting based on a light field camera. Background technique [0002] With the development of video and sensor technology, digital video content is gradually upgraded from a single low-resolution content format to ultra-high-definition, 3D and other content formats. For video shooting in a certain space such as sports events and indoor TV programs, multi-camera One-bit, multi-angle collaborative shooting is already a very commonly used technology. With the rise of VR and 3D technology, the use of 360-degree panoramic cameras and 3D cameras for shooting is also becoming more and more popular. [0003] However, the data collected by the existing video shooting method is only one or more planar images with preset positions and angles, and generally the appropriate angles are c...
