Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] Please refer to figure 1 , is a flow chart of Embodiment 1 of an image processing method for realizing seamless alignment of projection screens according to the present invention. Such as figure 1 As shown, the method starts at step S100, creating a D3D object on the video mixing renderer according to the image distributor and the image presenter, and assigning at least one D3D surface to process and display the grid image, in various aspects of the present invention In the embodiment, the entire image is composed of grids, so it is called a grid image. The size of the grid in the grid ima...

Abstract

The invention relates to an image processing method and a system for seamless alignment of a projection screen. The image processing method comprises the following steps of: S1, loading a grid image pre-stored by a user through an image distributor; S2, respectively regulating control points on adjacent grid curves in the grid image and control points on a curve surface to realize edge seamless alignment of adjacent grids of the projection screen on a D3D (Direct 3D) surface according to the Bezier law; S3, storing the regulated grid image in a grid file; and S4, displaying the grid image which is regulated on the D3D surface in real time by an image demonstrator. By implementing the technical scheme in the invention, the control points on the adjacent grid curves in the grid image and the control points on the curve surface are respectively regulated according to the Bezier law, thus seamless alignment of the projection screen is realized to ensure that an image is smooth and neat, and is processed by using various special effects of D2D.

Description

technical field [0001] The invention relates to the field of image processing of projection screens, in particular to an image processing method and system for realizing seamless alignment of projection screens. Background technique [0002] One of the most important new features in Microsoft DirectX 9.0 is the long-awaited merger of video and graphics rendering pipelines. Recently, DirectX 9.0 introduced the Video Mixing Renderer 9 (The Video Mixing Renderer-9, VMR-9) , VMR-9 is available on all platforms supported by DirectX, and uses the Direct3D surface to present video frames. Among them, Direct3D, referred to as D3D, is a set of 3D drawing programming interfaces developed by Microsoft on the Microsoft Windows operating system. Part of DirectX. [0003] VMR-9 has the following advantages: First of all, use all the processing conversion provided by D3D, for example, you can easily run the video stream through the pixel shader engine, so as to obtain customized video eff...
