Description

technical field [0001] The invention relates to the technical field of simulation. More specifically, it relates to a method and system for real-time generation of infrared scene images with dynamic distortion effects. Background technique [0002] Infrared imaging sensors working in turbulent atmospheric environments face complex transmission interference, which brings great difficulties to image recognition. How to simulate the dynamic distortion effect image caused by the interference environment is a key technology for evaluating the performance of infrared imaging sensors. Since the state of atmospheric turbulence changes rapidly and the calculation is very complex, the real-time performance of the simulation of image distortion effects cannot be guaranteed simply by relying solely on the commonly used dynamic optical scene image generation method based on the graphic calculation engine of the graphics card. The current distortion effect image simulation usually analy...
