Abstract The surface roughness of the joints affects their hydraulic and mechanical behavior. There are various methods for assessing discontinuities. With development photography technology release powerful software, a photogrammetric analyzer has been introduced as non-contact evaluation method. In this research, three-dimensional model fracture was constructed using close-range procedure joi...

By far, many stereo-matching techniques have been successfully proposed and applied in digital aerial photogrammetry. However, due to some problems such as large parallaxes, occlusions, geometric deformations, and repetitive patterns in convergent close range images, these methods may not be applicable to the same level of success as that of aerial imagery. In order to overcome these shortcomin...
