Embodiment 1

[0033] Such as figure 1 As shown, the method for real-time simulation of target visible light characteristics provided by the embodiment of the present invention includes the following steps:

[0034] First, in step S1, a target geometric model is constructed, and the geometric model is discretized into multiple panels.

[0035] In this embodiment, the target is a given target, such as a satellite, an airplane, and so on. When constructing the target geometric model, the existing 3D modeling software, such as UG (Unigraphics NX) and Inventor, can be used to construct the target 3D geometric model. When discretizing the target geometric model into multiple facets, meshing software in the prior art, such as Hypermesh, ICEM, Gambit, etc., may be used to discretize the target's three-dimensional geometric model into a large number of triangular facets.

[0036] In subsequent step S2, a target visible light characteristic data set is obtained according to the geometric model and the radi...

Abstract

The invention relates to a target visible light characteristic real-time simulation method and device, and the method comprises the following steps: constructing a target geometric model, and discretizing the geometric model into a plurality of surface elements; obtaining a target visible light characteristic data set according to the geometric model and the radiation characteristic parameters ofthe plurality of surface elements; training based on the target visible light characteristic data set to obtain a visible light characteristic model; and generating a target visible light image by using the visible light characteristic model. Compared with an existing target visible light characteristic simulation method, according to the method, the obtained visible light characteristic model isused for simulating the target and environment characteristics, a large amount of light tracking calculation does not need to be carried out under different light source and detection direction conditions, the requirement for real-time simulation of the target visible light characteristics can be met, and the method is particularly suitable for the situation that high-resolution image precision isrequired.

Background technique [0002] The current target visible light waveband characteristics simulation technology adopts a method of performing a large number of calculations through a ray tracing algorithm based on the physical process of actual light transmission for different detection directions, and finally generating a visible light image of the target and the environment. In the simulation process, a large number of ray tracing calculations are involved, and a large amount of calculation is required, especially when the precision of high-resolution image generation is required, the calculation amount increases sharply, so it is not suitable for real-time simulation. [0003] Therefore, in view of the above shortcomi...
