为了增加红外凝视焦平面阵列系统成像仿真的置信度,对系统中的成像几何扭曲效应进行了产生机理分析,从二维图像像素角度出发,在空域通过寻求各阵列元对应像素点的径向畸变量建立成像扭曲模型,并利用反演解析的方法对畸变图像中的像素灰度值进行估算,实验仿真结果表明,几何扭曲效应的存在严重影响了系统的成像效果,几何扭曲效应的建模仿真对后续的系统性能评估和算法研究至关重要。
In order to increase the confidence of the imaging simulation of the infrared gaze focal plane array system, the mechanism distortion of the imaging geometric distortions in the system is analyzed. From the perspective of two-dimensional image pixels, the radial distortion of pixel points corresponding to each array element is sought in the spatial domain The imaging distortion model was established and the gray values of the pixels in the distorted images were estimated by using the inverse analysis method. The experimental results show that the geometric distortions affect the imaging performance, modeling and simulation of geometric distortions Follow-up of system performance evaluation and algorithm research is very important.
