Subjeck of this diploma thesis is to familiarize with BIM and using laser scanning for creating BIM model.

This thesis deals with the creation of a BIM model using laser scanning. In the first part of the thesis, basic information about building information modeling (BIM) is described. The next section describes the process of creating a BIM model, from data acquisition to modeling or a particular building. The model was created in Revit.

The presented MSc. thesis is focused on the introduction and application of PDMS software in the process piping designing area. The introduction to the employing of the PDMS software is elaborated in the first part of the thesis as practical user manual of this software followed by the benefits of this software as a recognized supportive design program are consequently illustrated on partial solved cases from common design practice. The particular benefit of deploying PDMS in design practice is demonstrated in the thesis by economic evaluation of two selected solved industrial projection cases where design optimization of process piping system is solved with the support of this software system. Introduction of new ones broadening possibilities and current trends in the supportive design software systems, specifically using the scanner and supporting Everything3D are also presented as part of the thesis on a concrete example of the reconstruction of the boiler room.

The doctoral thesis deals with mobile laser scanning and data processing. Mobile laser scanning was carried out in the Moravian Karst in Suchy zleb and Pusty zleb at various seasons. Further scanning was carried out at the Training Forest Enterprise Masaryk Forest Křtiny. The Riegl VMX-450 scanner was used to collect 3D data. The data files were processed in the OPALS software. For the extraction of ground and non-ground points from the laser cloud, a combination of hierarchical interpolation and robust filtering was used. Subsequently, the terrain points were used to model digital terrain models with grids 0.05 x 0.05 m, 0.25 x 0.25 m, 1 x 1 m. Furthermore, digital models from Moravian Karst were compared with the Digital relief model of the Czech Republic 4G and reference points. Digital models from Masaryk Forest Křtiny were compared with photogrammetric and terrestrial data. The high accuracy of the derived DTMs is about 0.10 m. The high quality of the derived DTM can be used to monitor and analyze field changes and morphological structures.

The diploma thesis deals with the creation of a 3D model using laser scanning by unmanned aircraft (UAV). In the first part the author describes the history, legislation, the possibility of using unmanned aircraft and their dividing. The next section describes the process of creating a 3D model from data collection, using a drone to the actual modeling in Revit and subsequent use of the 3D model.

This thesis deals with the BIM creating process with the use of laser scanning data in Revit software. It’s focusing mainly on MEP of water object. In the theoretical part of thesis there are outlined basic issues about laser scanning, informational modelling and other relating issues. In the practical part of the thesis is the summarization of procedure starting from data collecting, data processing to the procedure of creating BIM model, it’s visualisation and the use of the model. There are also mentioned useful pieces of knowledge, which I have learned during dealing with the problems related to the application of this new way of using the spatial information.

The diploma thesis pointed out the possibility of using rapid prototyping methods in the field of plastic injection, specifically to make shaped inserts into the injection mold. The universal frame of the injection mold was used and only the shaped inserts were changed. The main part of the work was the construction of an injection mold with the subsequent practical production of shaped inserts for a specified part. In the introductory part, a theoretical search was performed, about which production methods in combination with suitable materials could be theoretically used. Furthermore, the polyjet and DLP methods were chosen, which were used to produce components (core and cavity). The result of the diploma thesis was a summary of all parameters, comparison of materials and production methods. Polypropylene and polyamide 6 materials were injected into the injection mold, from which the first prototype products were made. Instructions for the production of shaped inserts with the recommended technology and material were created for the selected type, which could be used in practice.

This diploma thesis deals with matte coatings for 3D scanning purposes. The coatings are made with spray gun which uses a vibrating membrane atomizer and air blow gun. A suspension of titanium dioxide and alcohol is used as a coating material. This thesis describes the effect of the spray gun process parameters on the deposited coatings. These include, for example type of the coating suspension or setup of the blow gun. Phase Doppler Anemometry was used to measure spray characteristics. Deposited coatings were measured with profilometer and scanned with 3D scanner to study their thickness and effect on the results of 3D reconstruction. The result of this work was the coating with thickness below 1 µm with good optical properties for 3D scanning purposes. Standard deviation of the captured point cloud from the reference plane was below 0.0011 mm.

The aim of this thesis is introduce the mobile mapping system IP-S2, which is using by company GEODIS BRNO, and perform data collection by this system. Measure the identical points, determine their coordinates and compare with coordinates obtained by mobile mapping system. The conclusion of this thesis is focused on testing the accuracy of the mobile mapping system.

The subject of thesis was creation of methodic for building information modeling methods specified. The buildings were surveyed at first or projects drawing were provided. Processing of survey data and building information modeling was done in software Revit 2014 with program extensions. Subsequently chosen methods of creation were described and they were compared with each other. The result can use for selection the most appropriate method on the basis function and targeted funds.
