Mapping of appearance and geometry of complicated industrial objects is a complex problem which requires that properly planned and prepared surveys are performed. Usually, detailed inventory must be performed for industrial objects. However, their complicated structure and difficult access to their entre surfaces result in limited visibility of the object. In this paper the commercially available CAD programmes (Kubit PointSense, LupoScan Pro, Autocad 2016 Geomagic Studio) are discussed; they enable the 3D modelli...

The historical Benedictine Abbey, which comes from the 12th century, consists of a basilica, monastery buildings and underground cellars. The underground of abbey, which is commonly unavailable for tourists, is not only historically valuable exhibit but also reveals condition of the foundations of the buildings, which has been built on a limestone hill above the River Vistula. In order to obtain spatial information of the underground of the abbey, scientists have made laser scanning of cellars and corridors under ...

Currently, terrestrial laser scanning is one of the most common method of measurement used for registration of the shape of objects. This technology enables in short time to designate huge collections of spatial data, known as point clouds. Due to the amount of occupied memory, storing large data sets becomes now a big problem. One solution is to create algorithms that allows to reduce the amount of recorded data without losing the essential spatial information. On the market there are mostly paid programs, that a...

Using of photogrammetric methods on quarries of dimension stone for determining cracks parameters and stone block modeling is actual problem. The methodology of applying the modern digital cameras (SLR-type) and terrestrial laser scanning for surveying of mining objects (dimension stone blocks), reception of the information on a camp of rock mass, recognition of cracks in rock massif with following definition of their geometrical parameters, quality control of dimension stone blocks on quarry are considered. The m...
