Monitoring and Security System
Felix, Martin ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
This master's thesis deals with design and implementation of system for securing and monitoring objects. The whole system is serving as an application getaway between typical TCP/IP network and heterogeneous network containing different end devices such as security cameras, microphones and some sensors (e.g. for temperature measurement). In case of detected event, the notification is created, recorded and the user is informed via administrative front-end. System can be managed from remote location and data from devices can be shown by web interface. Theoretical part of this project concerns with the analysis of different types of connecting devices and sensors and the possibilities of their usage for the monitoring systems along with description of communications protocols for each end device. The next part deals with the cameras interfaces, content analysis and connectivity with central server. Practical part describes methods and techniques used for implementation of system.

Stereoscopic sensor for distance measurement
Vavroš, Ondřej ; Říha, Kamil (referee) ; Hasmanda, Martin (advisor)
This master's thesis will take us through theoretical procedure that allows us to determine the distance of an object by stereoscopic sensor. Part of this work presents the description of the steps to achieve image of objects, calibraton and rectification. At the next part our study provides an overview of algortihms for creating disparity maps and determining the distance of the object from sensor. In the following part of thesis deals with the implementation of these processes into aplication which aim is to measure the distance.

Automatic positioning of the rear view mirror
Návara, Marek ; Richter, Miloslav (referee) ; Honec, Peter (advisor)
This thesis solves design of functional device that will be able to automatically positioning back view mirrors according to the positio of driver face. Measuring position of the face provides stereovision of two webacams. The device is based on a computer Raspberry Pi 2 with designed expansion board. The created prototype can follow set view int the mirror with accuracy up to 7 cm (horizontally up to 5cm) in level of rear corner of a car. The results of this project validate design of automatic positioning mirror and it can be basis for specific implementations of the device in car.

Measuring the Sun's position
Bajer, Patrik ; Čala, Martin (referee) ; Beneš, Petr (advisor)
The bachelor thesis deals with the design of a sensor for measuring the position of the Sun. In the first part, a theoretical analysis is made concerning methods of indicating the position of the Sun, patent searches and commercially available devices. The second part includes the preparation, the computer simulations performed, the actual design of the sensor and the evaluation of the results obtained.

Wireless robot control using mobile platform
Matuška, Jakub ; Kiac, Martin (referee) ; Přinosil, Jiří (advisor)
This bachelor’s thesis deals with design and implementation of an application for robot’s omnidirectional movement control using mobile platform. Implementation includes an Android application, used as user interface, as well as robot–side Python program for controlling movement and sending RTP stream to Android application. User can control robot’s movement using two virtual joysticks. Raspberry Pi was used as the control unit. The application has security module. Pipeline-based multimedia framework named GStreamer was used to implement RTP steaming. This paper describes necessary theory first and then introduces basic building blocks used in creation process of the application.

Gesture-Based Human-Computer Interface
Chaloupka, Jan ; Beran, Vítězslav (referee) ; Španěl, Michal (advisor)
This bachelor's thesis is about design and implementation of simple interface for hand gesture recognition. The interface is used as an extension of actual GUI elements. Skin color model is used for gesture segmentation, significant hand points (palm, fingers, fingertips) for gesture recognition. Designed interface is used for simple picture explorer controlling. Final application is capable of using simple gestures for scaling, rotation, pointing and click.

Use of Augumented Reality to Teach Guitar/Bass Playing
Kajan, Miroslav ; Zachariáš, Michal (referee) ; Šolony, Marek (advisor)
This final work deals with a design and implementation of a system suitable for teaching guitar playing by using the technology of augmented reality. A webcam and the musical instrument itself are necessary for a guitar player to achieve the main aim. The system is based on a principal of homography and other techniques to work with the image. The system also renders the tones of a chosen trained element (an accord or a scale) right into the image captured by a webcam.

Snow cover detection from webcam images
Fišer, Jan ; Brodský, Lukáš (advisor) ; Jeníček, Michal (referee)
This thesis deals with the possibility of using webcams as a source of spatial data for snow occurrence. The aim of this study is to propose a suitable method of snow cover detection from web camera images. From a sample of 6 webcams of the Czech Hydrometeorological Institute (CHMI) the snow cover is detected by pixel classification methods. The effect of training file size on the accuracy of classification is examined and the overall accuracy achieved by the SVM method was shown to be 97.46%. This study also aims to propose a system for determining the proportion of snow-covered areas. The algorithm consists of several sub-steps: filtering and registration of images, detection of snow, introduction of a coordinate system, calculation of the size of the surveyed area and the proportion of snow-covered area. The designed model can be used for automatic processing of images for various webcams. The melting curves of the snow cover are generated from the obtained daily values of the snow covered area. The results are validated using data from selected CHMI stations. The proposed and parameterized model confirms the possibility of successful use of webcams as a complement to ground measurement of meteorological stations and for the validation of remote sensing products.

3D scanner
Vrbičanová, Antónia ; Matějásko, Michal (referee) ; Spáčil, Tomáš (advisor)
The Bachelor Thesis deals with the creation of the 3D-scanner using webcam, laser, stepper motor, and Python programming language. The main goal of this work is to determine the accuracy and repeatability of the planar measurement using piece of the aluminum block by using specific methods of the image processing. By enhancement of measurement algorithm and stepper motor the coordinates of individual points a sample object are gained. It is possible to create a model in STL format from points coordinates using MashLab software.
