Problems solved by technology

In order to draw in real time, the traditional method adopts the combination of software and hardware, and uses the hardware system to realize the drawing of radar information. The effect is good, but the implementation is difficult and not flexible enough, and software and hardware are required to be developed together. With the rapid development of software technology in modern society, people begin to gradually Try pure software development, but generally the rendering effect is poor, and even affect other routine operations. Under the current background of software localization and software cross-platform, there is an urgent need for a high-efficiency and cross-platform radar information display method

no. 1 example

[0026] see figure 1 , figure 1 It is a schematic flowchart of an OpenGL-based radar information display method provided by an embodiment of the present invention.

[0027] Such as figure 1 As shown, the method includes:

[0028] S100: Create multiple video memory spaces in the video memory based on OpenGL.

[0029] The memory space is created based on OpenGL, and the specific amount of memory space can be set according to specific application scenarios and requirements.

[0030] S200: Convert the acquired initial radar information to obtain target display information.

[0031] S300: Update the target display information to the target video memory space through OpenGL, where the multiple video memory spaces include the target video memory space.

[0032] It can be understood that different video memory spaces correspond to different stored display information. For example, the display information is updated to the corresponding video memory space according to the correspo...

no. 2 example

[0036] This embodiment is based on the first embodiment. In this embodiment, S100 is described in detail. S100 specifically includes:

[0037] Call the drawing interface in OpenGL;

[0038] Create multiple video memory spaces according to the drawing interface and the preset total number of frames.

[0039] Initialize OpenGL, especially the OpenGL extension library. Call the GL_TRIANGLE_STRIP drawing interface in OpenGL, and the amount of drawing memory space is determined according to the total number of frames.

[0040] It can be understood that the total number of frames refers to the total number of frames of radar information reported by the radar in one week of scanning, and each frame corresponds to a different orientation.

[0041] Preferably, the amount of video memory space is greater than the amount of total orientations corresponding to the total number of frames. To ensure that relevant radar data information is not lost.

[0042] The number of scanning point...

no. 3 example

[0045] This embodiment is based on the first or second embodiment. In this embodiment, the initial radar information includes: previous frame data information and current frame data information, where the previous frame data information is adjacent to the current frame data information ;

[0046] Convert the acquired initial radar information to obtain target display information, including:

[0047] The data information of the previous frame and the data information of the current frame are respectively converted to obtain the target display information.

[0048] The data information of the previous frame and the data information of the current frame are original data, and both are stored in the local memory.

[0049] In this embodiment, the latest frame data information and the previous frame data information are always saved, and the target display information is obtained by converting the previous frame data information and the current frame data information respectively. ...

Abstract

The embodiment of the invention relates to a radar information display method and a system based on an OpenGL, and a storage medium. The method comprises: creating a plurality of video memory spaces in a video memory based on the OpenGL; converting the obtained initial radar information to obtain target display information; updating the target display information to a target memory space through the OpenGL, wherein the plurality of video memory spaces comprise the target memory space; and rendering the target display information through the OpenGL to display the target display information. According to the technical scheme provided by the embodiment, on the one hand, the technical disadvantage of the prior art that the radar information display is not flexible is avoided; on the other hand, the technical effect of displaying radar information with high efficiency is realized, and the technical effect of the cross-platform display mode of radar information is realized.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of radar information display, and in particular to an OpenGL-based radar information display method and system, and a storage medium. Background technique [0002] In the field of radar detection, radar terminal equipment is mainly used to display radar echo data, especially the original image of radar echo data, including distance, azimuth, intensity, etc., that is, radar information. At present, the combat system puts forward extremely high requirements on radar performance. The radar rotation period is even less than 10 seconds, and the radar echo data period is less than 10 milliseconds, and the radar echo data has the characteristics of high precision and long detection distance. For radar information The display needs to draw full-cycle data in real time at the same time, and the drawing pressure is very high. In order to draw in real time, the traditional method adopts the combi...
