Problems solved by technology

[0004] The main reason for affecting the generation of 3D models and their 3D resolution is image mismatch or even lack of match. Viewpoint angle of view, transmission transformation and occlusion will cause image mismatch or even lack of match, which will cause image registration to appear as a pathological problem in two-dimensional space.

Abstract

The invention relates to the technical field of naked eye 3D, in particular to a naked eye 3D model light field generation method and device, and the method comprises the following steps: obtaining scene information from a sequence image collected by a camera through uniform sampling; amplifying the region of interest in the scene information by utilizing global detection image pixel motion and global detection significance; in the region of interest, obtaining an initial three-dimensional model by solving the matching of the posture and the feature point of the camera; and performing digitallight field sampling on the initial three-dimensional model to obtain light field information of the initial three-dimensional model in different directions. According to the method, the technical problem that image registration is shown as an ill-conditioned state in a two-dimensional space due to mismatching or even matching loss of images is solved.

Description

technical field [0001] The invention relates to the field of naked-eye 3D technology, in particular to a method and device for generating a naked-eye 3D model light field. Background technique [0002] The current common glasses-free 3D technology, for example, uses dual cameras, equipped with a switch of liquid crystal lenticular grating, and cooperates with a large number of calculations to track the eyeballs, so as to achieve binocular parallax. Another example is the holographic pyramid, which can realize the 3D effect of large scenes and multiple perspectives. The static hologram on the holographic dry plate can achieve high resolution and full parallax observation effect. [0003] The inventor finds that there are following defects in the prior art in practice: [0004] The main reason for affecting the generation of 3D models and their 3D resolution is image mismatching or even lack of matching. Viewpoint perspective, transmission transformation and occlusion will c...
