| 摘 要： | 提出了一种观测六自由度振动的新方法，其基本原理是利用视觉摄像机监视被测物体，将物体图像实时采入计算机，通过对被测物体上三个特征点的成像位置变化的分析，计算出被测物相对于摄像机的六自由度振动。该测量方法属于绝对测量，尤其适用于任意低频运动的测量，曾成功应用于渤海油田ＳＺ３６－１贮油轮的运动观测。

| Abstract: | A new method for measuring vibration with six degrees of freedom is proposed. A video camera, as the reference, is used to monitor the object to be measured, and images from the camera are transmitted to a computer. By anaysing the coordinates of three points on each image, the total six parameters of vibration can be measured simultaneously. The method, belonging to absolute measurement, is particularly suitable for vibrations with low frequency. This method has been successfully employed in the measurement of vibration for SZ36 1 oil ship in Bohai oil field. |
