Embodiment Construction

[0021] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0022] Embodiment of the digital instrument panel drawing method based on OpenGL-ES of the present invention

[0023] The instrument panel drawing method of the present embodiment uses the OpenGL-ES basic instruction to draw, such as figure 1 As shown, the drawing process of the digital instrument panel mainly includes the drawing of lines, curve graphics, text content, background image superposition and distortion correction processing. The specific implementation process of each step is as follows.

[0024] 1. Use anti-aliasing to draw the lines of the digital instrument panel.

[0025] The essence of anti-aliasing is to establish a smooth gradient between the line color and the background color. When OpenGL draws a triangle, the part inside the triangle is the gradient of the vertex color. Therefore, the line (only for straight lines) ca...

Abstract

The invention relates to a digital meter panel drafting method based on OpenGL-ES and belongs to the real-time image display technology field. According to the method, an antialiasing drafting method is employed to carry out line drafting of a digital meter panel, lines drafted based on OpenGL-ES are divided into at least two triangles from edges to the center, and triangle vertexes are assigned with different transparency degrees to realize smooth fusion of line colors and background colors of the drafting result. The method is advantaged in that the lines of the drafted digital meter panel have no sawtooth, the edges and the background can realize excellent fusion, compared with full screen processing of an anti-sawtooth function defaulted by OpenGL-ES, drafting efficiency can be substantially improved through antialiasing line drafting.

Description

technical field [0001] The invention relates to a method for drawing a digital instrument panel based on OpenGL-ES, belonging to the technical field of real-time image display. Background technique [0002] At present, the human-computer interaction technology in aviation and car driving is developing rapidly, the degree of intelligence is getting higher and higher, and there are more and more video and radar sensors. Aircraft or cars have more and more complicated states. Traditional mechanical instruments It is difficult to display this information in a limited space, so digital instrument clusters are the development trend of driving technology. GPU (Graphics Processing Unit) has strong image processing and parallel computing capabilities. It is currently very popular in handheld devices such as mobile phones, set-top boxes, and tablet computers, and is used in more occasions involving mobile computing. Newer versions of Android run by default on hardware that includes a...
