A Method for Generating Aircraft Infrared Texture Image

Abstract

The invention relates to a method for generating an aircraft infrared texture image. Firstly, a three-dimensional model of the aircraft skin is established, data of the temperature field of the aircraft skin is acquired, and a three-dimensional temperature model is generated, and then a three-dimensional whiteboard model is derived, and the three-dimensional whiteboard model is textured to generate a color Coding model, compare the screenshots of the three-dimensional temperature model and the color coding model, fill in the temperature data of the corresponding position points into the color coding table, and obtain the temperature texture image of the aircraft; obtain the optical characteristic data of the aircraft, and add the optical characteristic data On the temperature texture image of the aircraft, an infrared texture image of the aircraft is generated. The present invention uses the color coding table to extract temperature point by point. Since the position and direction of the virtual camera are adjustable, the size and precision of the color coding table are also adjustable, so different precisions can be satisfied in the process of temperature extraction. Requirements, when the parameters are set properly, the results will be very accurate.

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
