摘    要:分析了当前红外遮蔽烟幕干扰面积和遮蔽率测试方法的主要问题,引入小波分析思路,利用多分辨分析方法将红外烟幕图像分割成多幅不同分辨率图像,组成层次式数据结构,然后利用小波变换的图像边缘检测算法画出烟幕云团边缘曲线,求出封闭曲线内面积,即可得到烟幕有效干扰面积和遮蔽率分布状态。这种方法解决了综合评定烟幕性能的若干问题,为研制烟幕弹或发烟装置提供了一种分析方法或思维方式。

关 键 词:信息处理技术  小波分析  烟幕  多分辨分析  红外  有效遮蔽面积  遮蔽率

Abstract:The main problems of current methods for testing interfered area of anti-infrared smoke screen and its obscuring ratio were analyzed. To improve the testing quality, a new method based on multi-resolution and wavelet analysis was explored. The infrared image of smoke screen is divided into some images with different resolutions, which compose a level-featured data structure. The fringe curve of smoke cloud image is drawn out and the closed area of the curve can be calculated via the image fringe-testing algorithm of wavelet transform. Thus, both the effectual interfered area and distribution of the obscuring ratio can be obtained. This new method can be used to assess integrally the performance of smoke screen. It also provides a reference for the development of smoke bomb and smoke device.
Keywords:information processing technique  wavelet analysis  smoke screen  multi-resolution analysis  infrared  effectual obscurant area  obscuring ratio
