In this study, digital image processing was used to estimate the tensile forces of the remote hanger cable using image-based back analysis method. A portable digital camcorder was used as a vision-based system considering convenient and economical aspects for use. The ambient vibration test was performed on a suspension bridge to verify the validity of the image-back analysis method of measuring the hanger cable tensile force.
