摘要：

A real-time system of numeral image manipulation technology is employed to inspect the dynamic displacement of an engineering structure. First, the CCD vidicon aims at the fixed point. The image of the fixed point on the structure is gathered by a picture gathering card. By processing pictures with a self-programmed software, the real-time space coordinate of the calibration device can be obtained. Finally, the data is dealt with to get the movement curve, and the dynamic displacement is carried out. The system is applied to the test of a high voltage icing conductor. The result indicates that the dynamic data of the ice shedding conductor includes jumping amplitude, displacement-time curve and attenuation process.
