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...

For the calibration of linear scales, comparators are generally used. Comparators are devices that enable the movement of an evaluation apparatus over a calibrated scale along a linear base with high precision. The construction of a comparator includes a movable carriage that carries the device for the evaluation of the position of the given edge o...
The paper deals with prototyping a kinematic measurement system for digitizing indoor environments of buildings. The scanning system itself consists of several sensors for localization (inertial measurement unit, rotary encoders and a stereo camera), while its main part is a Velodyne lidar.

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 t...

The main problem of the use of inertial measurement unit (IMU) lies in the systematic increase of position and orientation errors resulting from their functional principle. Position and orientation calculation based on the integration of inertial measurements (accelerations and angular velocities) leads to a rapid accumulation of errors of the iner...
An integral part of the construction works is the as-built documentation of the constructed structures and buildings and the check of the geometry of their parts. Moreover, in the nowadays era of automatization of processes, this procedure is often semi- or fully automated. For the data acquisition except for conventional surveying methods, terrest...
The information technology input for the building life cycle is more and more intensive, starting with design, through realization and including the use and the operation of the building. The progress in this field is represented by Building In-formation Modelling (BIM). BIM is in its base object-oriented 3D model of the building, which includes in...
Weather conditions and different operational loads often cause changes in essential parts of engineering structures, and this affects the static and dynamic behavior and reliability of these structures. Therefore, geodetic monitoring is an integral part of the diagnosis of engineering structures and provides essential information about the current...

Cranes are the basic tools for the movement of elements of equipment and products in industry or at the construction site. According to the shape and functionality, there are plenty of cranes. For safety use, it is very important to have their regular check and rectification. The chapter brings the basic classification of cranes, the basic requirem...
Maps used in the investment process, which are completed by specific content custom to the industrial plant and equipment, are important information sources. Surveying documents create a major part of documents used for design as well as the operation of industrial objects (plants). This chapter presents the factory base map and its design, creatio...
A development of production processes mainly in mechanical engineering production (a car industry, aviation, space industry) but also in the other similar industries causes increasingly requirements on the accuracy of a realization of products. Coordinate measuring machines are very important tools for quality checks in all kinds of manufacturing,...
Measurements done in the industry environment are very intensely influenced by specific conditions, which characterize the environment in industrial plants or enterprises. There are effects, which have a large impact on the measurement process, measured values, and on the measurement instruments systematically, which are very important to take into...
Nuclear power plants are very complex installations with specific requirements mainly on the stability of the base (ground). The assessment of the locality and the regular control of objects of the power plant are needed. The chapter brings the description of the main power plant objects and their function and operation conditions. The methodology...
One of the most used equipment in the production of materials for the building industry is the rotary kiln. Due to the big volume and high temperature, permanent deformations occur during the kiln operation. Considering these conditions, it is important to make regularly control measurements, mainly to check the fulfillment of the basic geometric p...
Construction of large investments usually requires a setup of a local geodetic network, which is above the national geodetic networks according to their density, as well as accuracy. Local geodetic networks are built for limited areas for the setting-out and deformation measurement of civil engineering structures or structures of large demand (high...
Laser scanning has become a part of the surveying practice during the last three decades of the development of scanning systems. Laser scanning technology is one of the most effective methods of spatial data acquisition and creation of 3D models in the present days. The advantage of the terrestrial laser scanning (TLS) to conventional geodetic meth...
Due to the intensive research in the field of development of sensors, measuring instruments or measuring systems, the level of industrial measurement is well developed. The quality of measurement is generally connected with using modern, high-quality, and verified instruments and measurement systems in the process. Parallel to this, the application...
For setting-out and verification of the geometry of different equipment in industry surroundings could not be used every geodetic method, due to the required high accuracy or non-accessibility of measured components for the geodetic measurement. In these cases are necessary to use measurement technology, instruments, and equipment, which are able t...
