Free perspective scene roaming method and device

Abstract

The present invention provides a method and device for roaming in a scene with a free view angle. The method includes: inputting the parameter information of the camera array and the position information of the virtual camera into the preset calculation model, and outputting the numbered coordinates of the target camera, where the numbered coordinates are used to represent the target The position of the camera in the camera array; if it is judged that the two numbers in the numbered coordinates are both integers, the target pixel in the image captured by the target camera is used as the virtual pixel in the virtual image captured by the virtual camera, and the target coordinate of the target pixel The same as the virtual coordinates of the virtual pixels, the target pixel value of the target pixel is equal to the virtual pixel value of the virtual pixel, so as to realize the free-view scene roaming. The free viewing angle scene roaming method and device provided by the present invention obtain dense viewpoint information from existing light field information, generate virtual images of virtual cameras, realize free scene roaming within a certain range, and realize real-time rendering.

Description

Technical field [0001] The present invention relates to the field of computer technology, and in particular to a free-view scene roaming method and device. Background technique [0002] The light field is a collection of light rays in different directions in space. Light field display is a display mode that can spread these rays in their original directions. [0003] In the prior art, the view point range displayed by the light field is limited by the content collected by the multi-camera array, and only the perspective information collected by the camera at a fixed position can be displayed. If you want to get the camera arrays in different positions to get the new display content, you need to reposition the camera positions and shoot again. [0004] However, this method in the prior art is very difficult in actual operation, and is not conducive to real-time rendering of the scene due to the large amount of data and the long time consuming. Therefore, how to obtain more viewpoin...
