Measurement of Rock Joint Surfaces by Using Smartphone Structure from Motion (SfM) Photogrammetry
The measurement of rock joint surfaces is essential for the estimation of the shear strength of the rock discontinuities in rock engineering. Commonly used techniques for the acquisition of the morphology of the surfaces, such as profilometers and laser scanners, either have low accuracy or high cos...
