Abstract

Scientific and fundamental metrology concerns the development of new measurement methods. Technology development evaluates in the emergence of new devices, methods and techniques, allowing to obtain spatial and geometric information about constructions with greater accuracy and less labour- and time-consumption. Applied metrology concerns the application of measurement science to their use in society. Such information is of great importance, since the use of these data can provide, for example, a complete view of the construction project documentation accuracy or will allow for further structure and facility monitoring, deviations of structures from the design project, sediment and overall construction state. Another important application is the imprinting objects, in particular listed buildings, in order to preserve their appearance, meaning the use of this data in the restoration or rehabilitation facilities. During the subsequent processing information can be transformed into other forms of fixation like drawings and three-dimensional model. Metrology has thrived at the interface between science and manufacturing. Particularly, Laser scanning and Photogrammetry methods found their wide application in solving practical tasks in architecture and building construction. These are the most common methods of obtaining this information. The article presents the description of both methods and discusses their advantages and disadvantages, as well as aspects, which determine the use of a particular method in different situations.
