The design of landslide monitoring and early-warning system in Opencast based on non-metric digital camera

Abstract

With the development of close-range photogrammetry technology and constant improvement of the common digital camera's resolution, the digital camera has become an important acquisition device to carry out the close-range photogrammetry image data. This article designed a set of practical landslide monitoring and early-warning System in Opencast with the improvement of the general digital camera and digital image data processing, combined the theory of deformation monitoring based on some research achievements in the field of traditional close-range photogrammetry, and discussed the main technology involved.
