In the opencast coal mining we face the excavation, transport and the storage of a substantial volume of materials. One of the main and regular tasks for surface mines are therefore the calculations of volumes and the monitoring the progress of extraction. The main objective of the measurement is to determine the geographic position of bucket-wheel excavators and lay down their basic geometric parameters, which define their position within three-dimensional space. This way we can monitor, plan and manage mining pr...

When documenting of existing bridges, object geometry knowledge is the highest importance. Complex construction documentation usually has limited spatial representation of the object, based on a limited number of basic forms of modeling, represented by edges, corners, planes and volume elements of the real object, and depending on the purpose, the model results must match within a certain accuracy with real object. Rehabilitation of bridges also involves the realization of detailed plans in situations where they n...
