Dic slope deformation measurement method and device

Abstract

A method and apparatus for measuring slope deformation using the DIC (Diverterless Computation) system, belonging to the field of slope measurement technology, is disclosed. This invention aims to improve the accuracy of slope displacement calculation. The invention includes a camera array, reference markers, a windbreak, and a field processing unit. The camera array is a multi-camera assembly composed of multiple high-resolution cameras fixed to a mounting bracket. Each high-resolution camera covers a specific sector, and the combined field of view of all high-resolution cameras covers the entire road slope. The reference markers are markers that emit near-infrared spectra and are fixed at monitoring points on the road slope; these markers have periodic textures achieved through a masking mechanism. The windbreak is positioned next to the mounting bracket to dampen wind-induced oscillations of the camera array. The field processing unit is a control and data processing device deployed at the monitoring site. The cameras in the camera array are connected to the field processing unit, and the camera array acquires images of the road slope with reference markers. This invention improves monitoring efficiency.
