Development of a Multi-Camera Based Photogrammetric Method for Improving Three-Dimensional Full-Field Displacement Measurements of Geosynthetics During Tensile Test

The research aims to develop a low-cost photogrammetric method for continuously measuring and tracking the 3-D full-field displacements and complete strains of geosynthetics during tensile tests. The proposed method will be non-contact, cost-effective, accurate, and capable of measuring the 3-D displacements of the geosynthetics at any location within the geosynthetics and at any moment during the tensile test. The proposed method can also identify any localized strains at any location within the specimen. The developed photogrammetric method from this study can be used in dynamic tests where the objects are continuously moving/deforming, such as tensile tests on the geosynthetics, which cannot be done by using the conventional one-camera-based photogrammetric method. Departments of Transportation (DOTs) and contractors can use the method for measuring the deformational response of geosynthetics with continuous movements or deformation.
