由于国内对紫外的视景仿真研究较少, 本文提出了一种基于日盲紫外波段的电晕成像仿真方法。该方法研究了试验电压和探测距离对绝缘子缺陷电晕放电的紫外光子计数的影响, 提出了改进的经验公式。提出了利用像素点对应紫外光子仿真电晕放电的算法, 得到了电晕放电的紫外仿真图像。通过在 vieWTerra视景仿真平台中建立绝缘子模型, 获得了可见光图像。将可见光图像和紫外图像通过加权平均图像融合方法进行融合, 得到日盲紫外波段的电晕成像仿真图, 为研究日盲紫外视景仿真提供了参考。

Due to the lack of domestic research on ultraviolet visual simulation, this paper presents a corona imaging simulation method based on the solar-blind ultraviolet band. This method investigates the influence of test voltage and detection distance on the ultraviolet photon counting of corona discharge from insulator defects, and proposes an improved empirical formula. To obtain the ultraviolet simulation image of corona discharge, a simulation algorithm is designed by using the pixel corresponding to ultraviolet photons. A visible light image is obtained by building an insulator model in the vieWTerra visual simulation platform. The visible light image and the ultraviolet image are fused by the weighted average image fusion method to obtain the corona imaging simulation image at the solar-blind ultraviolet band. This provides a reference for the study of the solar-blind ultraviolet vision simulation.
