Vision-based Displacement Measurement of Carbon steel tubes for general structural purposes and Steel pipe supports using DDVS Method
Applicability of vision-based dynamic displacement measurement system was evaluated to measure displacement caused by buckling under load on pipe. In order to analyze the accuracy according to the height of pipes, the height of carbon steel tubes for general structural purposes and Steel pipe supports is set to 0.5m from 2m to 4m. Dynamic Displacement Vision System (DDVS) method is used for vision-based displacement measurement and ROI (Region Of Interest) is set to track to solve the problem that the target deviates from ROI when displacement occurs. The displacement obtained by DDVS method is compared with the displacement measurement results of LVDT (The Linear Variable Differential Transformer) which is the contact displacement sensor. The square of the correlation coefficient ( R2 ) was used as the method of analyzing the error, and there is very little error regardless of the height of error.
