摘　　要：点扩展函数的设置是影响图像复原的关键问题。对于匀速直线运动模糊图像,模糊长度和运动方向决定了点扩展函数。分析了模糊图像的频谱图出现黑色条带的原因、条件以及它的精确位置,并设计了一种匀速直线运动模糊长度的估计算法,理论和实验证明这种算法是精确的。Setting the point spread function (PSF) of motion-blurred images is the key problem in image restoration. For uniform linear motion blurred images, the blurring length and direction determine PSF. The reason and condition of black strips in the spectrum images of motion-blurred images and specified the exact positions of black strips were analyzed. A method to accurately estimate the blurring length of uniform linear motion blurred images was introduced. That the method can get accurate result was proved theoretically and experimentally. Finally, the shortcoming of the method was pointed out.
