Abstract:
Rock mass characterisation is a crucial step in any rock mechanics project. Conventional mapping deals with
the visual interpretation of the rock mass as well with getting geometric measurements on the rock structures
such as discontinuity orientations. Since 3D images combine visual with spatial data it is a straightforward
approach to use them for supporting rock mass characterisation. Especially since drawbacks in the
conventional acquisition of the fracture network such as need for manual access, time restrictions, and
reproducibility can be overcome. From digital photographs three-dimensional models are built that allow us
to measure rock mass features directly. This paper describes a modernised version of the well-known
photogrammetric approach enhanced by Computer Vision principles. The advantages of this approach are
that zoom lens can be used for measurements, pictures can be taken freehand, and data processing does not
require knowledge on photogrammetry. Besides the concept and the measurement possibilities some
applications are addressed.
