| Abstract: | A real-time monitoring system of digital image processing technique was developed to detect the dynamic displacement of project structure.First the CCD vidicon was put on fixed point,the video picture of sign points were gathered on inspected structure by picture gathering card.Second the picture in the cache was processed asynchronous by using the multithread programming technique.It can automatically track and recognise aims.At last the result is exported.It ensures that the system is real-time.The system is applied successfully in detecting other bridge structures. |

| Keywords: | dynamic displacement image processing curved surface approximation dynamic tracking subpixel multithread programming technique |
