3D Model Reconstruction and Camera Localization
Vahalík, Tomáš ; Materna, Zdeněk (referee) ; Beran, Vítězslav (advisor)
This thesis focuses on reconstruction of 3D environment model from a set of photographs followed by camera localization. It describes basic principles and techniques used to create environmental models and techniques for camera pose estimation from 2D camera points to 3D model points. It also examines the influence of parameters on the quality of reconstruction and the possibilities of localization. It compares the quality of the descriptors in the process of creation of the model and based on localization it allows to implement augmented reality.

3D Objects Detection in Images
Bordovský, Gabriel ; Veľas, Martin (referee) ; Španěl, Michal (advisor)
This bachelors thesis deals with detection of a known 3D object in images and its pose estimation. The method uses the ORB-type keypoints and their location on the surface of a bounding box. By using solve of PnP problem a pose of the object is obtained using the points 2D coordinates from the image and the 3D coordinates of the very points from the registered model. This thesis expands a detection method for simple box-shaped objects, which is a part of OpenCV library, for the usage on more complex objects. In experiments, the detector reached a detection success rate of 85 % and the computed pose matches the real one approximately for 88 %.

Panoramic Photo Creation
Dospiva, Filip ; Sochor, Jakub (referee) ; Behúň, Kamil (advisor)
This thesis contains a comparison of approaches to implementation of the panoramic photos. There are analyzed partial steps to create panoramas and access methods that are used for these steps. There is a preview of the methods and schedules their advantages and disadvantages. Also included is a comparison of these methods and evaluation of their usability.

Birds Eye Panorama
Sobotka, Lukáš ; Pavelková, Alena (referee) ; Kolář, Martin (advisor)
The goal of this paper is to create panorama from the collection of photographies, which are taken from randomly moving device with OS Android. The device is placed on flying vehicle (a kite, a helium balloon, a drone etc.). The photographies are taken from birds eye view. The Android application was created and tested. This application creates a collection of photographies and then runs an algorithm to create panorama. This algorithm specifies descriptors using SURF, which are filtered by RANSAC algorithm for finding the optimal homography.This algorithm is perfomed iteratively over the collection. The image data is processed using the OpenCV library.
