Metric survey documentation of the part of the main palace of Veveří Castle
Biriukov, Ilia ; Volařík, Tomáš (referee) ; Machotka, Radovan (advisor)
The main aim of the master's thesis is to create documentation for the southern part of the 3rd floor of the palace with a pointed tower in the Veveří Castle complex, based on laser scanning and measurements using the Faro Focus 3D device, and to create a 3D model of the area of interest. This documentation includes floor plans, sections, and elevations of the building's facades, and it is an integral component for the future reconstruction. To achieve this aim, the master's thesis consists of two parts: theoretical and practical. The theoretical part describes the measured object and the measurement methods used. The practical part includes an analysis of the acquired data and detailed descriptions of the data processing steps in various software programs such as SW Groma, Trimble Real Works. It presents methods for creating 2D drawing documentation and 3D wireframe model supplemented with surfaces using Autodesk AutoCAD and Trimble Business Center software. All of these steps are aimed at obtaining high-quality documentation that will serve as a basis for the reconstruction of the building.

Edge detection and representation in point clouds
Večeřová, Alena ; Druckmüllerová, Hana (referee) ; Procházková, Jana (advisor)
This thesis discusses edge detection and representation in point clouds. For the detection of edge points was used clustering of normals. The RANSAC method is used to represent the line edges. Within the work, the edge points of one model are also interspersed with a circle using the least squares method and projective space. All methods were implemented in MATLAB and tested on real data obtained on the ATOS CompactScan 2M scanner.

Metric survey documentation of the cellars in the northern part of the main palace of Veveří Castle
Míča, Vojtěch ; Volařík, Tomáš (referee) ; Machotka, Radovan (advisor)
This diploma thesis is focused on the creation of survey documentation of the cellars under the northern part of the palace with a tear-shaped tower, located within the Veveří State Castle complex. Data collection in the field was carried out using 3D laser scanning technology, and the resulting point cloud served as a basis for the production of 2D contruction documentation drawings, which include three floor plans and six vertical sections at a scale of 1:50. The first part of the thesis defines the location and addresses the issues of surveying of historical sites. The second part describes the measurement process and details the methods and instruments used. The third part of the thesis deals with the processing of the measured data and the creation of the final construction documentation drawings.

Construction documentation using information modelling
Kudláček, Lukáš ; Škrla, Petr (referee) ; Kuruc, Michal (advisor)
The bachelor's thesis deals with the creation of As-Built documentation by generating individual drawings from the digital model of the object of interest, which was created on the basis of a point cloud. The first part describes the preparatory work and the theoretical introduction. The second part of the work deals with the measurement of control points in the field. The third part is dedicated to office work, which includes the processing of measured data, digital model creation, generation of project documentation drawings and their modification into the final form, and last but not least also visualization of the model of the object of interest. The digital model was created in OpenBuildings Designer CONNECT Edition. Visualization took place in the LumenRT extension and the MicroStation CONNECT Edition program was used to edit the drawings of the project documentation. Based on the digital model of the object of interest, a 1:50 scale model was subsequently created using 3D printing technology.

Documentation of optical network route using low-cost lidar equipment
Březina, Jan ; Vondrák, Jiří (referee) ; Machotka, Radovan (advisor)
This work aimed to test the potential benefits of handheld lidar for optical network route documentation. For this purpose, a lidar embedded in an Apple iPhone 14 Pro mobile phone was used. The work provides insight into the issues of both the data acquisition by this device and the subsequent processing and evaluation of the route, including the surrounding topography. All the procedures have been documented and their findings written into the text to facilitate familiarity with the equipment used. Problems encountered during scanning and data processing were outlined. Also, comparisons were made with currently used methods. The evaluation of the accuracy of the measured data was carried out by independent measurement of the features using the GNSS method. Based on the acquired data, documentation of a part of the newly surveyed route was made at the selected location according to the guidelines of the optical network administrator. The outputs of this thesis can be used to discuss the possible use of the tested scanner today as well as in the future.

Stereo Reconstruction with Deep Neural Networks
Letanec, Richard ; Herout, Adam (referee) ; Španěl, Michal (advisor)
The aim of this thesis is to design and train a neural network model capable of estimating a disparity map from a pair of images. It will then be possible to create a depth map and point cloud from the estimated disparity map. Such a process is called stereo reconstruction. Solving this task consists of two steps -- choosing a suitable dataset and choosing a suitable neural network architecture. In my work, I compared two neural network architectures that I trained on the DrivingStereo dataset, consisting of paired images photographed from the roof of a car, and retrained and evaluated on the KITTI 2015 dataset, consisting of images of the same type. As the first neural network architecture, I chose ES-Net, which uses an approach based on a sequence of residual blocks and convolutional layers. As the second architecture, I chose CREStereo, which uses an iterative approach based on recurrent layers to predict the disparity map. In all benchmark tests, the CREStereo architecture achieves better accuracy.
