Problems solved by technology

[0004] At present, since most manufacturers can only provide decoded video data in YUV format for decoding video images, and graphics cards do not support the display of YUV images, the usual practice is to convert YUV data into RGB data and then display them, but Such conversion is done in the CPU, so it will take up a lot of CPU time and reduce display performance.

Embodiment 1

[0025] see figure 1 , figure 1 It is a schematic flowchart of an embodiment of a three-dimensional image-based video surveillance image display method provided by an embodiment of the present invention. The embodiment of the present invention provides a three-dimensional image-based video surveillance image display method, including steps:

[0026] 101. Input the decoded YUV video image to the graphics card through the OpenGL interface to obtain YUV data.

[0027] In the embodiment of the present invention, in order to display the video image, at first certain decoding processing must be carried out to it; then, the YUV video image after the decoding processing is input to the graphics card through the OpenGL interface, and the graphics card obtains the YUV data;

[0028] 102. The graphics card GPU programs the YUV data to obtain programmed YUV data.

[0029] After step 101, the decoded YUV video image is input to the graphics card through the OpenGL interface. After the gra...

Abstract

The invention provides a video monitoring image display method based on a three-dimensional image. A decoded YUV image is input into a graphics card through an OpenGL multiple-texture interface. The GPU of the graphics card is programmed by means of a shading language. The GPU of the graphics card converts the texture of the YUV image to an RGB image by means of a transformation rate and displays on a display device. Compared with the prior art, the video monitoring image display method has advantages of no occupation of a large amount of GPU time and effective display performance improvement.

Description

[0001] This application is based on the Chinese patent application number 201510121156.X, the applicant is Guangzhou Sanchuantian Culture Technology Co., Ltd., and the name is "Based on the community environment multi-dimensional comprehensive management of 3D image video surveillance image display method" as the application of the priority document . technical field [0002] The invention relates to the technical field of camera monitoring, in particular to a three-dimensional image-based video monitoring image display method. Background technique [0003] Video image processing is the core component of the video surveillance system, and the processing of video image display is the core of the core. [0004] At present, since most manufacturers can only provide decoded video data in YUV format for decoding video images, and graphics cards do not support the display of YUV images, the usual practice is to convert YUV data into RGB data and then display them, but Such conver...
