Dynamic Monitoring of Structures Using a Robotic Total Station

In recent years, some researches have revealed the advantages of using a robotic total station (RTS) for dynamic monitoring of structures. The advantages include the automatic target recognition, autonomous operation, once lock to the target has been manually set by an operator, monitoring of moving objects, the possibility of measuring indoors. However, the use of robotic total station for monitoring the movement of civil structures is still limited to the fact that angles and lengths are measured with time slide that the size is not known yet. This paper reports sets of experiments performed at LAIG (Geodetic Instrumentation Laboratory) of Federal University of Paraná. These experiments were conducted to gauge the accuracy of Leica TCRA 1205 for monitoring of a moving target on vertical plane. A particular equipment was designed to simulate the “up and down ” movement of a low frequency deformatting structure. Furthermore, the robotic total station was conducted to a field experiment. A historical bridge was monitored using the RTS for measuring angles and distances at a 2 Hz data rate. RESUMO Estudos recentes têm revelado as vantagens do uso de estações totais robotizadas (ETR) n
