Abstract

The invention relates to a method for manufacturing a screen surface matched with undulating surface spatial characteristics. The method comprises the following steps of: acquiring elevations of four angular points of a square two-dimensional base plane in an area required to be simulated, performing repeated iteration on the square two-dimensional base plane to obtain the elevation data of the characteristic point of a pseudo screen surface through a random midpoint method by utilizing the elevations of the four angular points; analyzing the spatial characteristic parameters of the area required to be simulated and the pseudo screen surface, obtaining the similarity of the spatial characteristic parameters, and obtaining a comprehensive similarity; and manufacturing the pseudo screen surface matched with the area required to be simulated according to the generated elevation data of the characteristic point of the pseudo screen surface when the comprehensive similarity meets the requirements. According to the method, the roughness and undulating degree of the screen surface and the mean height fluctuation range can be controlled by utilizing an attenuation factor in the random midpoint method, and the fineness of the screen surface is controlled through the iteration frequency; and the generated pseudo screen surface and the area required to be simulated have a good fusion effect, and the method is suitable for manufacturing the screen surface of the simulated earth's surface with high undulating degree.

Description

technical field [0001] The invention relates to a method for producing a shielding surface, in particular to a method for making a shielding surface that matches the spatial characteristics of the undulating surface. Background technique [0002] Target recognition technology based on image feature analysis is becoming more and more mature. As a countermeasure, on the basis of looking for all possible target and background characteristics that can be used as identification basis, camouflage should try to cover up the difference between the target image and the background image in the detectable feature set. [0003] In the color image, the shadow area of ​​the undulating surface has the following unique properties compared with other areas: ①Because the sun’s rays are blocked in the shadow area, its brightness value is lower; ②Due to the influence of atmospheric Rayleigh scattering, the scattered light in the shadow area It mainly comes from blue-violet light with a shorter...
