Due to usage, handling, and improper storage, measuring tapes undergo changes in their condition over time. For this reason, regular inspection is necessary to ensure the desired quality of results, aiming to verify the accuracy of the tape and its usability in practice. During the calibration of measuring tapes, the position of the scale divisions on the tape is evaluated using a device known as a horizontal comparator. This device consists of a linear base on which a carriage with evaluating equipment, in our ca...

The article deals with the developing and applying of the mobile mapping system developed at the Department of Surveying of the Slovak University of Technology in Bratislava. The article presents a low-cost mobile mapping system for simultaneous localization and mapping of the indoor environment. Existing systems are costly and have robust construction and high-power requirements, making them unavailable for some applications. The proposed measuring system consists of three orthogonally placed 2D lidars, a robotic...

BIM (Building Information Modeling) allows the use of a virtual building model throughout the whole life cycle of the building. It is a parametric object-oriented 3D data model of a building, which contains information about structures, elements, and their parameters. The combination of the BIM model with detailed data on the as-built geometry of the building enables an effective geometry check of the structural elements, which leads to in-time intervention in the building process if needed. The requirement of eff...

Nowadays we see an increase in traffic intensity all around the world. The traffic infrastructure is extremely loaded by the traffic, which causes deformation of its parts. In addition to traffic load, significant is the effect of the weather conditions (wind, sunshine, temperature changes). All the mentioned effects cause changes in the spatial position and in the shape of the bridge structures. Due to these facts, geodetic monitoring is an integral part of bridge structures diagnosis and gives important informat...
