Embodiment Construction

[0046] An implementation example of the present invention is described in detail as follows in conjunction with accompanying drawing:

[0047] The specific steps of the new viewpoint reconstruction method in the multi-viewpoint acquisition / display system of the convergent camera are as follows: figure 1 The flow chart is shown. For the modeling scene, it is programmed on the computer platform; for the actual scene, the experiment is carried out by establishing a convergent camera acquisition and display system. Figure 7 Gives the viewpoint reconstruction result.

[0048] see figure 1, the new viewpoint reconstruction method in the multi-view acquisition / display system of convergent cameras, first establishes the camera geometric model for the convergent camera acquisition method, and then designs the viewpoint reconstruction filter according to the acquisition system parameters, scene geometric information and spectral characteristics, and the inner Interpolate sampled ima...

Abstract

The invention relates to a novel viewpoint rebuilding method in a multi-viewpoint collection/display system of a converge type camera. According to a collection mode of the converge type camera, first, a geometric model of the converge type camera is built, each parameter related to the collection system is comprehensively considered, an optimized condition of distortionless rebuilding viewpoints is obtained through signal sample theory analysis, then spectrum analysis is performed on EPI image on the scene, relation between scene EPI spectral characteristic and scene depth span is obtained. Based on the above analysis, the number of the sample image is determined, and a viewpoint rebuild filter is designed, a sample image is generated for the rebuilt viewpoint through interpolation technology, finally a novel viewpoint of a three-dimension scene in certain range is obtained through the converge model designing and plotting rebuild method. In experiment, verification is respectively performed on an analogue system and a practical system with similar parameters, obtaining excellent rebuilding quality. The invention is of reference value for other camera array types and viewpoint rebuilding system.

Description

technical field [0001] The invention relates to a new viewpoint reconstruction method, in particular to a new viewpoint reconstruction method in a convergent camera multi-viewpoint acquisition / display system. Background technique [0002] In recent years, 3D TV and free-viewpoint TV systems have attracted much attention due to their unique stereoscopic, immersive and roaming characteristics. However, the construction of a multi-view acquisition and display system needs to involve various technologies from acquisition, data representation, compression and transmission to interactive display. In the application of multi-viewpoint acquisition and display system, if a larger number of camera arrays and dense acquisition arrangements are used, the system can use a simpler rendering and reconstruction method to reconstruct three-dimensional light data (that is, new viewpoints) without distortion. However, this kind of system is only optimal in theory, and it is difficult to reali...
