Problems solved by technology

[0002] Traditional high-definition screenshots for massive 3D data require full loading of the data, sometimes due to the exhaustion of memory resources, resulting in abnormal image effects or abnormal generation of images
In the high-definition screenshot solution, it is a common practice to divide the screen area into multiple pieces of data and take screenshots separately. The magnification of a house does not manage the memory. Therefore, in the process of these screenshots, it is difficult to cause the problem of excessive memory resource usage, and the stability can be guaranteed.
However, when the data of the entire city or even the whole country needs to be screenshotted, there will be a large amount of data bottleneck problem. In the process of high-definition screenshots, there will be problems such as high memory usage and poor screenshot stability.

Embodiment 1

[0019] A region segmentation screenshot method, which divides the image data of the screen area into N equal parts in the horizontal direction and the vertical direction to form a magnification factor N, and divides to obtain N*N equal-sized screen data area blocks, and each screen data area block is called It is an image unit, identified by n rows and n columns, because the screenshot is to capture the scene image data of the entire screen, the screen needs to be divided into N*N blocks, and the resolution of the resulting image must be N times the screen size, and then every On each screen data area block, by setting specific screenshot parameters, the data of the screen data area block is enlarged by N times, and the screenshot is taken. The size of the generated picture is the same as the size of the entire screen, and the effect is also enlarged by N times, so as to achieve high-definition screenshots. The function also includes the following steps:

[0020] (1) The curre...

Embodiment 2

[0030] Same as Embodiment 1, the difference is that the projection relationship is perspective projection.

Embodiment 3

[0032] The same as in embodiment 1, the difference is that after a certain area is divided, when the ratio of the C value to the V value is equal to 0.2, the m value is increased.

Abstract

The invention relates to the technical field of computers, and discloses a region segmentation screenshot method. The method comprises the following steps: respectively dividing screen region image data into N equal parts in horizontal and vertical directions so as to form a magnification time N and obtain N*N equal-dimension screen data region blocks, wherein the screen data region blocks are called as image units and identified in n lines and n rows. The method furthermore comprises the following steps: (1) converting new screenshot parameters of the image units according to the magnification time N, a screen resolution and a projection relationship, and distributing line and row numbers for the image units after the parameter calculation, wherein the current screen resolution is W*H, the magnification time is N, the picture dimension is (W*N)*(H*N), and the new screenshot parameters comprise viewport dimension and view frustum dimension; and (2) carrying out data region segmentation in an image unit in a certain line and a certain row. The method disclosed in the invention has the effects of reducing the memory usage during the screenshot and being good in screenshot stability.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a region segmentation and screenshot method. Background technique [0002] Traditional high-definition screenshots for massive 3D data require full loading of the data, and sometimes due to the exhaustion of memory resources, the image effect is abnormal or the image cannot be generated normally. In the high-definition screenshot solution, it is a common practice to divide the screen area into multiple pieces of data and take screenshots separately. The magnification of a house does not manage the memory. Therefore, it is difficult for the problem of excessive memory resource usage to occur during these screenshots, and the stability can be guaranteed. However, when the data of the whole city or even the whole country needs to be screenshotted, there will be a bottleneck problem of large data volume. In the process of high-definition screenshots, there will be problems...
