抽油机游梁振幅的视频检测

A Video Measuring for the Vibration Amplitude in Beam of Pumping Units

针对抽油机游梁振幅的动态检测要求,提出一种远程位移视频测试方法,采用CCD摄像头摄取测试位置运动图像,然后利用计算机图像处理技术识别、提取目标点,最终得到游梁振幅的实时测量结果。方法的最大特点是无需在测试位置安装目标点,这对人员不便到达的游梁的检测是非常必要的。

According to the dynamic measurement for vibration amplitude in beam of pumping units, a measuring way of the displacement of remote objects is presented. Using a CCD camera to get the object image, and a computer to recognize and pick-up the target, the real-time data of beam vibration amplitude are obtained. The experiments prove that the system without setting spot manually can be used in fields of remote measurement where the observer is incapable of approach.
