Vibration displacement measurement of pipe system based on high-speed photography technology
Aiming at the low precision of the problem of high-speed photography technology at a longdistance measurement of the vibration response in the test,a method combining bicubic interpolation with Sobel operator edge detection image technology is proposed to improve the measurement precision.At first,the shaking table test of pipe system with two measuring systems,high-speed photography and accelerometer,is designed.Secondly,the image measured by the high-speed camera system and the acceleration vibration response measured by the accelerometer are processed,and the displacement vibration response data is extracted.Finally,the displacement vibration response data measured by high-speed photography and accelerometer are compared in time domain and frequency domain,and analyzing the accuracy of data measured by high-speed photography.The results show that the image measured by optimizing high-speed photography technology combined with bicubic interpolation and Sobel operator edge detection image processing can obtain high-precision displacement vibration response data to meet the measurement and use requirements.
