Summary
A new application based on photogrammetry to measure displacements in three dimensions is shown in this paper. Results of displacements for a torsion test of a 3m long beam and 0.50 x 0.50m in cross section under laboratory conditions is presented and a comparison with traditional measurements by potentiometers is presented to check the validity of the photogrammetric method. The three-dimensional photogrammetric method demonstrates good accuracy and allows for a continuous measurement of a three-dimensional body. The technique presented can be used to monitor displacement with good accuracy.
