Applying digital vision metrology to monitor the behavior of rock slopes

We have studied the slope monitoring method using digital vision metrology. This study developed a technique for measuring the deformation of a slope without setting any fiducial points. The method of simply obtaining initial approximations of coordinate values from the images is applied to the new measurement technique. This measurement method has the advantage of obtaining the three coordinates of many measurement points at cheap cost. In this paper, the precision of the measurement values obtained by the proposed technology is verified in the actual rock slope. The feasibility based on the experimental results to the design of countermeasure construction is discussed.
