Integration of multi-sensor observations (GPS, total station) for high accuracy measurements, stability check of control points, identification and separation of various causes of deformation. Laboratory exercise: A total station is used to measure the relative position of points with respect to the position of the robotic total station (RTS) with automated target recognition (ATR). Small targets are placed in the areas of interest throughout the object being monitored; the RTS is programmed to point to these targets and make precise measurements. The measurements are performed in the predefined pattern and schedule. The raw data are collected by RTS and then processed by the software to determine the final coordinates, displacements, displacements velocities of all the target points. Verification of the results. Optional: Multi-sensor observations (GPS, total station) for high accuracy and stability check. Mining example: excavated areas in open pit mines require stability monitoring to guide production and safety (steeper walls mean more efficient use of resources, but may be more prone to failure) application accurate displacement monitoring system.
