Abstract

This paper reports on a study to develop the technology to monitor the behavior of a slope using the digital camera images of the slope. Specifically, it deals with a monitoring system that allows the highly precise reproduction of slope shape from a number of images taken from various directions. The study explores an analytical method that uses the Moore-Penrose generalized inverse matrix for an equation derived from the geometrical relation between the camera, measurement points and photographed images, obtains the distance between measurement points installed on the target slope by the minimum-norm least-squares solution without setting any control points, and discusses the technology to monitor slope behavior based on the changes in the distance obtained. Furthermore, the precision and accuracy of the measurement values obtained by the proposed technology is quantitatively verified, and its applicability to slope monitoring is examined.
