Title:
HIGH-SPEED MULTI-DIMENSIONAL VIBRATION MEASUREMENT APPARATUS AND METHOD BASED ON STRIPE TARGET
Document Type and Number:
WIPO Patent Application WO/2016/127486
Kind Code:
A1
Abstract:
A high-speed multi-dimensional vibration measurement apparatus based on a stripe target, comprising a stripe target (9), an imaging module (3), a signal control and processing module and a display module and a high-speed multi-dimensional vibration measurement method based on a stripe target, comprising arranging a stripe target (9) on a vibration structure (8) to be measured; continuously imaging and recording the stripe target (9) using the imaging module (3); the imaging module (3) transmitting an image of the stripe target (9) to a signal control and processing module; the signal control and processing module performing Fourier transformation on stripes at the same position of an identical stripe target in each frame of the image, accurately correcting a peak value frequency using a certain peak value frequency correction method, and then obtaining a time domain curve with structure vibration at the stripe target by means of an imaging mathematical relation and the corrected peak value frequency, that is, obtaining structure vibration signals through reduction; and displaying an image processing result via a display module or performing further data processing by means of the vibration signals. The apparatus and method can achieve vibration measurement for points, lines and surfaces within a certain range, and both the measurement speed and the accuracy are high.
