摘要
An on-line tunnel deformation monitoring system based on image analysis and its application comprises identification points, an IP camera, a central control computer, as well as a transmission network and the application of the system includes the following steps: 1) lay the identification points; 2) the central control computer controls the zoom photography of the IP camera periodically; 3) the IP camera transmits the photos to the central control computer; 4) the central control computer conducts self-adaptive filtering transformation for the photos; 5) the central control computer conducts grayscale threshold transformation; 6) the central control computer conducts image edge detection to obtain the identification points; 7) calculation of the arch crown settlement displacement and the arch springing convergence displacement of the identification points; 8) judge whether the arch crown settlement displacement and the arch springing convergence displacement are both less than the set thresholds, and if they are, return to Step 2), otherwise give an alarm.
