METHOD AND DEVICE FOR ESTIMATING MECHANICAL PROPERTY OF ROCK JOINT

摘要

A method and devices for estimating a mechanical property of a rock joint are presented. The method comprises obtaining a plurality of at least partly overlapping photos of the rock joint by at least one optical sensor comprised in a device, wherein said photos represents the rock joint from different perspectives or positions, generating a digital three-dimensional representation of the rock joint based on said plurality of photos, and determining the mechanical property of the rock joint based on the generated digital three-dimensional representation
