Point Tracking

For point-based measurement of 3D coordinates and their tracking over the time course of dynamic or (quasi-)static tests, measuring objects are given ultra-light measurement targets. The 3D coordinates of every measurement target are measured by photogrammetric methods with subpixel accuracy. In a measurement, the point tracking method can be combined with the digital image correlation method. Grouping several measurement targets creates characteristic constellations that can be tracked by the software over time. Therefore, at the end of the image processing, the coordinates, displacements, velocities and accelerations for each measurement target are available for evaluation.
