Abstract:

This paper proposes a method of 3D dynamic object reconstruction based on light field rendering. At the present, for IBM(image based modeling) it is difficult to construct models for complex scene, while for IBR(image based rendering) real-time rendering of dynamic scene is infeasible due to a large amount of data. Thus in this paper, we introduce the method of modeling associated with images. We reconstruct 3D dynamic model from multi-view video images, utilize LFM(light field mapping) algorithm to sample light field of 3D model, and then decompose and compress the samples. The experimental results show that the proposed method can reduce amount of data while guaranteeing the realities, and realize reconstruction of 3D dynamic object.
