摘要: 安装在旋转平台上的成像传感器随着平台的高速旋转,其所成图像将产生严重的旋转模糊。针对旋转模糊图像模糊长度径向可变的特点,提出了一种基于路径提取的旋转模糊图像复原算法。主要是通过径向提取图像的模糊路径,求得各个路径上的模糊长度,将二维旋转模糊图像复原问题转化为一维的线性信号复原。仿真实验结果表明,相较于对数极坐标、最小二乘法复原算法,所用算法计算量小,复原效果明显。

Abstract: The imaging sensor, which is set on a rotating plat, rotates with the plat at high speed. As a result, the images is be blurred badly. According to the space-variant of the rotary image, the rotary trails are extracted and the rotary length of each trail is gained. The two-dimensional image restoration is transformed into one-dimensional signal recovery. Two restoration methods are proposed. The first method is based on the Weiner filter, and the second methods is based on the diagonal loading arithmetic. Compared to the previous method, such as the minimum-square method and the logarithmic polar coordinates method, the two methods make better performances with little calculating time.

Key words: information processing technology, image restoration, rotary blur, trail extraction, circular minimum deviation interpolator, Wiener filer, diagonal loading
