摘要
介绍了一种新的根据图像的运动模糊信息测量高频振动振幅的方法.与现有的基于计算机视觉的振动测量方法相比,该方法仅通过计算1幅清晰参考图像及1幅运动模糊图像的前2阶几何矩即可得到2D高频直线振动振幅的解析解,降低了根据图像信息测量振幅的计算复杂程度.实验结果表明,所提出方法可有效地测量高频振动的振幅.
This paper presented a novel motion-blur-based method for measuring the amplitude of high-frequency vibration. Compared with the existing vision-based method for vibration measurement, this method obtains the analytical results of the amplitude of high-frequency vibration by calculating the first and second order geometric moments of a motion blurred image and an unblurred reference image. This reduces the computational complexity for vibration measurement from images. Experimental results were provided to prove the effectiveness of this method.
