Aircraft infrared texture image generation method

Abstract

The invention relates to an aircraft infrared texture image generation method. The method comprises the following steps: Firstly, an aircraft skin three-dimensional model is established; obtaining aircraft skin temperature field data; a three-dimensional temperature model is generated, then the three-dimensional white board model is exported, mapping processing operation is carried out on the three-dimensional white board model, generating a color coding model, screenshot comparison on the three-dimensional temperature model and the color coding model, and filling the temperature data of the corresponding position point is filled into a color coding table to obtain an aircraft temperature texture image; And optical characteristic data of the aircraft is acquired, and the optical characteristic data is added into the aircraft temperature texture image to generate an aircraft infrared texture image. According to the method, the temperature is extracted point by point by using the color coding table, and the position and direction of the virtual camera are adjustable, and the size and precision of the color coding table are adjustable, so that different precision requirements can be met in the temperature extraction process, and the obtained result is very accurate when the parameter setting is appropriate.

Description

technical field [0001] The invention belongs to the technical field of image processing and simulation, and in particular relates to a method for generating an aircraft infrared texture image. Background technique [0002] The development of infrared guidance technology has promoted the development of infrared stealth aircraft. Take some effective measures to weaken or suppress the infrared radiation energy of the aircraft, so that the attacking missile can only detect the aircraft in the shortest possible distance, making it difficult for the missile to attack the aircraft in a short distance, reducing the hit probability, and the so-called aircraft can be realized. Infrared stealth improves the survivability in infrared confrontation. [0003] At present, there are mainly two classic methods for the research on the infrared radiation characteristics of aircraft. One is to compare the flight data in the real environment with the theoretical data through flight tests, and t...

Problems solved by technology

[0005] The infrared texture of aircraft skin includes temperature characteristics and optical properties, but the temperature field data calculated by CFD can only represent its thermal characteristics

In the 3D infrared simulation of aircraft skin, the 3D temperature data is directly used, which does not include the optical properties of the aircraft skin, cannot reflect the optical properties of different parts of the aircraft, and it is difficult to correct the simulation results
