Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] like figure 1 As shown, this embodiment is aimed at the forward-looking infrared sensor that is typically configured in modern aircraft, fully considers the computational complexity of each part of infrared imaging physics and the characteristics of airborne real-time imaging simulation, and divides the imaging simulation into preprocessing, real-time generation and airborne effect. Combine three parts.

[0034] In the preprocessing part, the scene infrared characteristic data and material characteristic data of the three-dimensional scene are obtained, as well as the imaging model data of the infrared sensor;

[0035] In the real-time generation part, according to the theory of infrared radiation, a signal perception simulation model is established, which interacts with the corresponding attributes described in the virtual environment...

Abstract

The invention belongs to the technical field of computer virtual reality simulation, and particularly relates to a large-scale scene infrared imaging real-time simulation method for an airborne enhanced synthetic vision system. The invention relates to a forward-looking infrared sensor which is typically configured for a modern airplane. The invention discloses a physical model based on infrared radiation. Establishing signal perception simulation model, under the action of corresponding attributes described by a virtual environment, detection signals are output in real time through a virtualreality simulation engine, a flight instrument is superposed, the infrared video imaging working process of an enhanced synthetic vision system of an airplane in the flight process and image degradation caused by an airborne severe imaging environment are simulated, and real-time simulation of a large-scale scene is achieved. According to the method, the comprehensive effect of target infrared radiation is simulated by comprehensively utilizing factors such as infrared band radiation characteristics, geometric characteristics of the target and atmospheric effect, so that detail information isnot distorted, artificial traces such as manual mapping in a traditional algorithm are avoided, and the method has a relatively good calculation effect and simulation precision.

Description

Technical field: [0001] The invention belongs to the field of computer virtual reality simulation, in particular to a large-scale scene infrared imaging real-time simulation method for an airborne enhanced synthetic vision system. Background technique: [0002] In recent years, enhanced synthetic vision technology (system) based on forward-looking infrared images has been more and more widely used in aircraft. By superimposing instruments on three-dimensional scenes, it can provide pilots with Vivid scene information, and the display effect is enhanced by superimposing colors and symbols in advance, which greatly enhances the pilot's situational awareness ability under low visibility or low-altitude flight conditions. [0003] However, the actual flight test environment of the enhanced synthetic vision system is complex, expensive, and the cycle is long, and the system without mature test certification is difficult to load into the airborne platform for verification, and it ...
