Object deformation fields (magnitude and direction) can be determined with maximum efficiency and precision using photogrammetric technology.
A standard application for photogrammetric deformation measurement is climate testing for automotive plastic parts or deformations of machines under load. On the right the deformation of a car (Fig. 1 and Fig. 2) and a stamping press (Fig. 3 and Fig. 4) are shown at different load conditions.
The measuring principle is a least squares photogrammetric bundle adjustment. Two or more deformation states for the target object are established. Transforming the two resulting datasets into a common coordinate system (vehicle-fixed or floating), the deformations are shown as vectors.
In these examples we measured deformations of a few tenths of a millimeters. The 3D representation gives an overview of the spatial orientation of the deformation. The resulting vectors can be color-coded and projected into the images (separated by coordinate directions).
The Linearis3D Photogrammetry Professional is ideally suited to static measurements.
The Linearis3D Video is ideally suited to dynamic measurements.
We will advise you on which measured values matter — and recommend the right system.
