This study introduces a vision-based system for displacement measurement using in civil engineering. Target panels are attached to a structure. The images of targets captured by camcorders are streamed into the PC via frame grabbers, and the software will calculate the displacement of target by applying image processing techniques with pre-measured calibration parameters. Many experiments are carefully conducted to verify the cost-effective, efficiency, stability and accuracy of this system.
