Problems solved by technology

The disadvantage of this method is that in the spatial frequency filtering model based on distance information established by this method, the target can only exist in the inherent background in the real-shot infrared texture image, and cannot simulate background changes and targets in different weathers. Conditional Background Questions
The disadvantage of this method is that because infrared and visible textures have different formation principles, a single proportion factor of infrared and visible light texture information cannot be used to adjust all detailed scenes when processing large-scale scene information. The simulation method can be applied to only Large-scale infrared simulation scenes that require a small amount of detail, but it is not suitable for use in infrared scene simulations that require a large amount of detail
The disadvantage of this method is that when calculating the size of the target at different imaging distances, the size of the target at different imaging distances is directly calculated according to the physical size of the target in the scene, and the number of imaging pixels at different imaging distances is not accurately calculated according to the principle of infrared imaging. To calculate the target imaging size, and did not consider the different atmospheric infrared transmission effects at different imaging distances, resulting in low imaging accuracy and affecting the size of the target in the imaging scene

Abstract

The invention discloses a target and background fusion simulation method based on actually measured infrared imaging data. The target and background fusion simulation method is mainly used for generating infrared images of a target at different backgrounds and different positions in the backgrounds. The method comprises the following steps of implementing the method; Shooting infrared images, calculating the actual size of a target in the target infrared image; calculating the radiation brightness of the infrared features generated by the target in the target infrared image, separating the target infrared image in the infrared image, calculating the infrared features of the analog target in the analog infrared imaging system, fusing the infrared features of the analog target and the background, and outputting an infrared simulation image in which the analog target and the background are fused. The method can obtain the backgrounds of the target under different conditions and the infrared images at different positions in the backgrounds, and has the advantages of high authenticity and rich detail features of the infrared target image generated by simulation.

Description

technical field [0001] The invention belongs to the technical field of image processing, and further relates to a target and background fusion simulation method based on measured infrared imaging data in the technical field of infrared image processing. The present invention can fuse two infrared images of the separately shot target and its intended space background (such as a ship and the ocean) into one image, complete the infrared imaging simulation and synthesis of the target and the background, and simulate different distances and different background environments Infrared imaging fusion simulation of target and background. Background technique [0002] Infrared imaging simulation is a simulation of the infrared radiation distribution of the scene in terms of time, space, spectrum and radiation. The simulation of infrared images can generally be divided into target simulation, background simulation, effect simulation of fuzzy objects such as atmosphere and battlefield ...
