Free visual scene roaming method and device

Abstract

The invention provides a free visual scene roaming method and device. The method comprises the following steps: inputting parameter information of a camera array and location information of a virtualcamera into a preset computation model, and outputting a serial number coordinate of the target camera, wherein the serial number coordinate is used for representing the location of the target camerain the camera array; and if judging to acquire that two numbers in the serial number coordinate are the integer, taking the target pixel in an image shot by the target camera as the virtual pixel in avirtual image shot by the virtual camera, wherein the target coordinate of the target pixel is same as the virtual coordinate of the virtual pixel, and the target pixel value of the target pixel is equal to the virtual pixel value of the virtual pixel, thereby realizing the free visual scene roaming. Through the free visual scene roaming method and device provided by the invention, the dense visual point information is acquired from the existing light field information so as to generate the virtual image of the virtual camera; the free scene roaming in a certain range is realized, and the real-time rendering is realized.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular to a method and device for roaming in a free-viewpoint scene. Background technique [0002] A light field is a collection of light rays in different directions in space. The light field display is a display method that can spread these light rays in their original direction. [0003] In the prior art, the viewpoint range of the light field display is limited by the content collected by the multi-camera array, and only the perspective information collected by the cameras at fixed positions can be displayed. If you want to obtain new display content from the camera arrays in different positions, you need to rearrange the camera position and shoot again. [0004] However, this method in the prior art is very difficult in actual operation, and it is not conducive to the real-time rendering of the scene due to the large amount of data and the long time consumption. There...
