Embodiment Construction

[0070] The technical solution of the present invention will be described in detail below in conjunction with the embodiments.

[0071] The present invention proposes a new calculation method for depth extraction of 3D objects in an integrated imaging (II) system, calculating the similarity of pixels in each element image while projecting them to possible depths. Surface continuity is also taken into account for improved resolution. And use the patch matching method to speed up the computation.

[0072] Figure 1(a) and Figure 1(b) are schematic diagrams of the principle of integrated imaging (II). 1(a) is a schematic diagram of the pick-up part of the comprehensive imaging (II), and FIG. 1(b) is a schematic diagram of the projection part of the comprehensive imaging (II).

[0073] Referring to Figure 1(a), the letter A denotes a three-dimensional (3D) object. Z (capital letter) represents the distance between the object and the lenslet array, and g represents the distance be...

Abstract

The application discloses a three-dimensional (3D) object depth extraction method, and solves the problem that the algorithm is too complicated in the current 3D image depth information extraction process. The 3D object depth extraction method obtains the depth of the pixel by calculating the similarity between adjacent pixels in each element image in a 2D planar image. The extraction method is a fast and accurate 3D object depth extraction method, which considers the synthesized imaging (II) and synthetic aperture integral imaging and develops a depth extraction mathematical framework based on a Patch-Match algorithm by assuming that a 3D object is a surface composed of many aspects. The application also discloses a device adopting the above 3D object depth extraction method.

Description

technical field [0001] The invention relates to an information extraction technology in the field of optical information engineering, in particular to a technology for extracting depth information of a three-dimensional image. Background technique [0002] As a next-generation display technology, three-dimensional (3D) imaging technology has developed rapidly in recent years. Integrated imaging (II) (English: Integrated imaging (II)) involves its high resolution and full parallax. It is compatible with traditional image processing techniques such as super-resolution and image matching. In order to realize 3D imaging and display. Integrated imaging (II) requires different perspectives from 3D objects (called elemental images), which are usually picked up by small lens arrays in general integrated imaging (II) systems. Due to the use of standard 2D images, multiscale 3D imaging systems can be constructed using a single inexpensive camera with an array of small lenses or an ...
