Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] Refer to attached figure 1 , the concrete steps of the present invention are as follows.

[0035] Step 1. Obtain two parallax images.

[0036] Use two cameras of the same model and randomly placed horizontal and vertical distances to capture any 3D scene within the overlapping field of view of the two cameras, and obtain parallax image 1 and parallax image 2.

[0037] Step 2, determine the image point with the same name.

[0038] Take any pixel in parallax image 1 as the center, determine a square central image block and search window; select a search window of the same size as parallax image 1 in parallax image 2, and take each pixel in the search window as The center point determines multiple image blocks with the same size as the central image block.

[0039] The side length of the central image block ranges from 11 to 23 pixels, and the side le...

Abstract

The invention discloses a method for obtaining a micro cell image array in real time based on double cameras. The real-time obtaining problem of the cell image array meeting any display requirements in three-dimensional integrated imaging display is mainly solved. The method comprises the following implementation steps: (1) obtaining an anaglyph; (2) searching homologous image points; (3) obtaining a motion vector array; (4) generating a middle micro cell image array; and (5) generating a display unit image array. The method disclosed by the invention has the advantages that the cell image array meeting any display requirements can be generated under the condition of not setting the distance between the double cameras, so as to achieve real-time obtaining of the micro cell image array; the method can be used for image obtaining of a three-dimensional stereoscopic television and real-time collection and display of a three-dimensional scene.

Description

technical field [0001] The invention belongs to the technical field of image processing, and further relates to a method for acquiring micro-unit image arrays in real time based on dual cameras in the technical field of three-dimensional integrated imaging and display. The invention can be used for real-time acquisition and display of three-dimensional real scenes, and image acquisition of three-dimensional stereoscopic televisions. Background technique [0002] The three-dimensional integrated imaging technology includes two stages of micro-unit image array acquisition and reconstruction, and micro-unit image acquisition is divided into two methods: computational generation and optical acquisition. The former has problems such as huge amount of calculation, generation speed, positioning and viewing angle analysis, and it is difficult to model the real scene; the latter is generally acquired by lens array or camera array. Realize real-time acquisition of 3D real scene. Cam...
