Problems solved by technology

However, the disadvantage of this method is that the data source only considers the geometric parallax information of the original three-dimensional object viewed at certain angles, compared with the original three-dimensional object, a large amount of geometric information is lost, so the obtained micro-unit Image arrays are less effective
However, the disadvantages of this method are that, firstly, when the method is executed, the color value of each pixel of the micro-unit image array is affected by many points in the three-dimensional scene, so if the method runs in parallel, it will be difficult to guarantee Each pixel in the micro-unit image array obtains the co

Embodiment Construction

[0043] Below in conjunction with accompanying drawing, the present invention will be described in further detail:

[0044] Refer to attached figure 1 , the steps that the present invention realizes are as follows:

[0045] Step 1, generate a 3D terrain scene.

[0046] Using a visible light CCD camera, obtain the visible light image of the actual three-dimensional scene orthogonal projection. Using a depth camera, a depth image of the actual 3D scene is obtained.

[0047] Using the terrain mesh reconstruction method, the visible light image and the depth image are transformed into a 3D terrain scene.

[0048] The specific steps of the terrain mesh reconstruction method are as follows:

[0049]The first step is to use the depth value of each pixel in the depth image of the actual 3D scene as the height of the small cuboid, and the pixel side length of the depth image as the length and width of the small cuboid to construct a small cuboid, and use the pixel point in the visib...

Abstract

The invention discloses a method for integrated imaging micro-unit image parallel generation based on particle tracking. The method is mainly used for solving the problems that an existing micro-unit image generation method is poor in degree of parallelism and low in speed. The method mainly comprises the following steps that (1) a three-dimensional terrain scene is generated; (2) a micro lens is placed; (3) a micro-unit image array plane is placed; (4) a pixel point number is obtained; (5) tracking particles are emitted; (6) the tracking particles are moved; (7) color of an initial emitting point is replaced by background color; (8) the color of the initial emitting point is replaced by surface color; (9) whether the tracking particles exist or not is judged; (10) the tracking particles are moved continuously; (11) whether a pixel point number value is equal to N or not is judged; (12) a result is generated. On the basis that the imaging quality of a generated micro-unit image is guaranteed, the method for integrated imaging micro-unit image parallel generation based on particle tracking has the advantages of being high in degree of parallelism and high in operation speed.

Description

technical field [0001] The invention belongs to the technical field of image processing, and further relates to a method for parallel generation of integrated imaging micro-unit images based on particle tracking in the technical field of integrated imaging. The invention can quickly obtain micro-unit images taken from different angles, and realizes three-dimensional optical reconstruction of objects in combination with an integrated imaging display device. Background technique [0002] In 3D integrated imaging, it is often necessary to generate a micro-unit image array based on a 3D scene. The traditional micro-unit image generation method, one is to use the CPU to generate a micro-unit image array according to the object model according to the method of ray tracing; the other is to use a three-dimensional rendering engine similar to Microsoft Direct3D (hereinafter referred to as D3D), according to the virtual surface model, rendering each microcell image one by one. When ...
