Aiming at the low precision of the problem of high-speed photography technology at a lo ngdistance measurement of the vibration response in the test,a method combining b icubic 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 i mage measured by the high-speed camera system and the acceleration vibration respons e measured by the accelerometer are processed,and the displacement vibration response data is extracted. Finally,the displacement vibration response data measured by high-speed photog raphy and accelerometer are compared in time domain and frequency domain,and analyzing th e accuracy of data measured by high-speed photography.The results show that the image mea sured by optimizing high-speed photography technology combined with bicubic interpolatio n and Sobel operator edge detection image processing can obtain high-precision displacement vibration response data to meet the measurement and use requirements.
