Research Of Equipment Vibration Parameters Based On Image Processing Technology

This item mainly used of time-seal technique and the method with two high-speed video cameras in different directions, one at the side face, the other at the rear, so can we made the two cameras be controlled synchronously and solved the testing difficulty about multi-direction parameters of gunpoint vibration. In the item, the synchronous control precision is about few ns. By using modified optimum whole threshold method and area morphology mean, we made the object points on the image can be carried out automaticly. We established the mathematical model of gunpoint vibration parameter testing and data processing pattern. With the help of high-speed video processing technique and outward scaling technique, we completed the gunpoint vibration parameter testing task about a repeating ack-ack gun the first time at home. and we also set up the homologous relationship between gunpoint vibration and pills scatter on the target. The methods in our achievements named without-contact methods can be used to measure the vibration with higher frequency and little amplitude.
