A simulation method of infrared imaging based on opengl shader

Abstract

The invention discloses an infrared imaging simulation method based on an OpenGL shader. The method includes the steps that firstly, a scene infrared effect is rendered, the capacity for absorbing light of all ground objects is resolved, and if all heat of the non-self-heating ground objects is derived from solar energy, the infrared effect picture of a scene to be simulated is approximately rendered; detail textures of a target are made, temperatures of all components of the target are collected under the approximate environment condition in a limited-time mode, a linear model of a target temperature value and a target grey value is established, the grey value is resolved to make the textures, and finally the textures are smeared on the corresponding components; the scene and the target are fused, and the OpenGL shader is adopted for drawing the detail textures on all details of the original target in the scene; atomization and noise corruption are performed on a fused infrared image, an atomization effect is added to the image with an eyespot distance as reference, and then noise is added. The image which has an equivalent effect under the observation of an infrared imaging system can be presented in real time, and image quality is stable and reliable.

Problems solved by technology

[0003] Multigen's Vega software is the most widely used computer simulation imaging software, especially at present, Vega software has an infrared software package, which is easy to use, and can quickly build a prototype of complex visual and sound simulation, but the obvious shortcomings of this software are: China Not authorized to use the Vega infrared module. In addition, the software is expensive and the portability is not strong, which also restricts its application.
