Several experiments were performed that demonstrate the applicability of these remote sensing techniques to monitoring rock mass changes. An improved, or augmented, method for measuring displacements underground in a practical, cost-effective manner will lead to an improved understanding of rock mass behavior. Photogrammetry and laser scanning offer the ability to monitor rock mass movements at millions of points in a local area, both accurately and quickly. These are generally restricted to measuring one dimension, may change behavior with installation, may obstruct mining operations, and are restricted to monitoring theīehavior of a small area. Displacements underground are traditionally measured through point measurement devices, such as extensometers. Photogrammetry and laser scanning are remote sensing technologies with the potential to monitor movements of rock masses and their support systems in underground mine environments. Our goal is to evaluate Catch efficiency, accuracy, constraints and limitations in order to provide insight into the cu. Our research investigates the limits and potentialities of 3D models obtained by using Autodesk 123D Catch in Architectural Heritage field, in order to verify the applicability of the method for the practitioner purpose. In this way is overcome the considerably slowing-down of the computer of hardware-heavy approaches. Nevertheless, web based software (ARC3D, 123D Catch, Hyp3D, m圓Dscanner) offer another opportunity respect the desktop systems: they use the power of cloud computing to carry out a semi-automatic data processing. The diffusion of Image-based 3D modeling techniques, through image-based free, low cost and open source software, have increased drastically in the past few years, especially in the sector of Cultural Heritage (Architecture, Archeology, Urban planning). Today, the accurate and detailed reconstruction of geometric models of real objects has become a common process.
