The purpose of this review is to introduce these easy to use
photogrammetric techniques to the general structural geology and
paleoseismology communities while illustrating a range of applications.
A variety of 3D data collection tools are now available to the
geoscientist, including a range of laser scanning options and
traditional surveying methods, and each method has different advantages/disadvantages
in terms of resolution, scalability, portability,
and computer processing requirements. Photo-based 3D
reconstruction techniques can provide a comparable resolution to
laser scanning tools with a significant reduction in cost, infrastructure,
and processing requirements. To assist with adoption of
such techniques, we provide an overview of the technical basis
along with workflows and discussion of best practices for photograph
collection that will provide optimal results.
