Vyhodnocení dat pořízených bezpilotním prostředkem / Evaluation of data acquired by UAVSetnický, Viktor January 2016 (has links)
This thesis deals with the application of unmanned aerial vehicles (UAV) in photogrammetric purposes useful in geodesy. The UAV that was used for imaging is described in the first part, also there are introduced two programs which were used for data processing. A system of mission planning and data collecting is shown on the ortofoto creating as an example. The second part of this thesis deals with testing of the accuracy through terrestrially independently measured points. The main aim of the work is to demonstrate the high potential of UAV devices for geodesy purposes.

Fotogrammetrická analýza obrazů / Photogrammetric Image AnalysisVelebová, Jana January 2011 (has links)
This thesis is dedicated photogrammetric image analysis that makes it possible from your photos with the help selected methods to determine the location and dimensions of objects recorded on them. There are explained the basics of photogrammetry and its current application. Chapters focused on digital imaging describing its characteristics, treatment options and key points findability for the scene calibration. For a comprehensive view are in this thesis introduced examples of existing software, its possibilities and use in practice.

Testování přesnosti mobilní fotogrammetrie / Accuracy testing of mobile photogrammetryOtrusinová, Jana January 2020 (has links)
This diploma thesis deals with a construction of a calibration field in the area of the AdMaS research centre (Brno University of Technology). Furthermore, photogrammetric data from the Riegl VMX-450 mobile mapping system has been acquired and processed. Selected points of the calibration field were used as control points. The other points of the calibration field were used as check points. As part of the testing, the coordinate deviations at the check points were assessed. The difference between the accuracy of mobile laser scanning and mobile photogrammetry was also evaluated. Coordinate deviations of mobile photogrammetry were tested according to standard ČSN 01 3410. Furthermore, a point cloud and a textured 3D model were generated.

Kombinace laserových a snímkových dat z mobilního mapovacího systému / Combination of laser and image data from a mobile mapping systemStránská, Petra January 2021 (has links)
The diploma thesis describes the data integration of data from different 3D technologies, specifically data of close range photogrammetry, aerial photogrammetry using RPAS and terrestrial laser scanning. The thesis deals mainly with fotogrammetric processing in ContextCapture software and data integration in this software. The thesis also describes a construction of a calibration field. The points of the field were used as ground control points and check points during processing. The accuracy of the outputs was evaluated by statistical testing of the coordinate deviations of the control points. The result of the thesis is 3D model of one of the buildings located in the AdMaS research center.

Fotogrammetrické snímaní polohy jezdce na motocyklu / Photogrammetric localization of motorcycle riderLečbych, Jiří January 2021 (has links)
This Master’s thesis deals with designing a measuring device that would record driver’s movements during dynamic riding states known as localization, and based on the recorded data creating a simulation in multi-body software. The first part reviews the current state of knowledge in the field of photogrammetry, sensors, and motorcycles’ characteristics. Moreover, the second part focuses on constructing the measuring device, practical aspects of data collection, processing, and evaluation in multi-body software.

Zpracování dat pro 3D / 3D data processingBabinec, Tomáš January 2009 (has links)
The thesis falls within the field of computer vision. It describes the development of the software environment for 3D data processing. The thesis deals with the design of C++ classes suitable for scene description and representation of bonding conditions between scenes elements. There is also discussed the solution of camera calibration, geometric distortion identification and 3D coordinates reconstruction. The solving of these tasks is augmented with planarity and linearity conditions, which support projection equations and augment the computational ability of the environment.

Zpracování snímků pořízených z UAS / Processing of images taken from UAVRoubal, Pavel January 2014 (has links)
The aim of the thesis was to process the images taken by UAS technology and especially to test the accuracy of this method on the checkpoints of various types. For this testing were used checkpoints that were measured by geodetic method. Subsequently these points were compared with points measured photogrammetrically.

Využití programu PHOTOMODELER v soudně inženýrské praxi / Use of PhotoModeler program in forensic engineering practiceZdražilová, Alena January 2015 (has links)
The main task of this thesis is to find out dimensions of family house from photos and after that use this dimensions to create a 3D model. Another task is to create and then test optimal procedure of taking photographs of house for the purpose of work in PhotoModeler software and subsequent processing in Autocad. The result is a model that serves for creation of sections and taking measurements necessary for valuations of a family house. The optimum process should be a compromise of the simplest and the most accurate method of creating 3D models.

VYUŽITÍ METOD OPTICKÉHO SKENOVÁNÍ V GEOMORFOLOGICKÝCH ANALÝZÁCH / THE USE OF IMAGE MATCHING METHODS IN GEOMORPHOLOGICAL ANALYSISŠiková, Zuzana January 2015 (has links)
The use of optical scanning methods in geomorpho-analysis Abstract Main goal of this thesis is to find out if it is possible to use Structure from motion (SfM) method for analyzing geomorphological objects. Four geomorphological features in three different places within Pilsen-North region was used for testing this method. These objects with very dissimilar dimensions and shapes was scanned for this testing in various light conditions. All used data-sets was entirely created by author of this thesis. The data was initially processed by Agisoft Photoscan Professional Ediditon v1.1.6 and VisualSFM v0.5.26 to create spatial models. These models was afterwards processed in CloudCompare v2.6.1 and MeshLab v1.3.3. This software was used for clipping and merging of 3D models and for converting 3D models in to real dimensions. These real sized spatial models was then contrasted together by creating comparing entities. Outcomes are evaluated in the thesis conclusion. Keywords: Structure from motion (SfM), SIFT, RANSAC
