| Abstract | The available conventional sensors like displacement transducer used in Structural Engineering laboratory are expensive. In addition to that, the need of data acquisition device also escalates the expense invested for point contact measurement system. The recent appeal of vision-based measurement technique and search for cost-effectiveness has led to exploration of the established sampling moiré method using cheap CCTV cameras as a viable option. The sampling moiré method is simple and analyzes the displacements from grating images by phase shifting method. A series of trial experiments that were conducted, which demonstrated that the setup is at least as accurate as the more traditional measuring system. An experiment was conducted in a steel I-beam for displacement measurement which has displayed satisfactory result. In addition, the setup was also tested for strain measurement and it has yielded promising result that needs fine tuning. This thesis discusses the challenges, findings and possibility of incorporating vision-based displacement measurement in laboratory platform. |
