Detta examensarbete utreder avståndsbedömning med hjälp av bildbehandling och stereoseende för känd kamerauppställning. Idag existerar ett stort antal beräkningsmetoder för att få ut avstånd till objekt, men metodernas prestanda har knappt mätts. Detta arbete tittar huvudsakligen på olika blockbaserade metoder för avståndsbedömning och tittar på möjligheter samt begränsningar då man använder sig av känd kunskap inom bildbehandling och stereoseende för avståndsbedömning. Arbetet är gjort på Bofors Defence AB i Karlskoga, Sverige, i syfte att slutligen användas i ett optiskt sensorsystem. Arbetet utreder beprövade Resultaten pekar mot att det är svårt att bestämma en närmask, avstånd till samtliga synliga objekt, men de testade metoderna bör ändå kunna användas punktvis för att beräkna avstånd. Den bästa metoden bygger på att man beräknar minsta absolutfelet och enbart behåller de säkraste värdena.

This thesis deals with use of Information technology for analysis of exposure to advertising communications, focusing on outdoor advertising.In the theoretical part is a brief outline of the beginnings and development of advertising, its effects on people, whether it can change their consumption behaviour, its position in the modern world and the way new technology along with psychology can be used for its analysis. The second part gives insight in the practical research of effects of outdoor advertising on people. There is an approach of Eye Camera technology in praxis, preparation for research, problems solved in its course. Data obtained are both verbally and graphically interpreted.

My master's thesis goes in for new term neuromarketing and its specific application in a quality marketing research. In a theoretical part I will present terms like marketing, marketing research and neuromarketing. In an application part I will introduce a company Vodafone, whose campaign will be analyze from many views. Firstly I will analyze an advertising campaign with a help of its emotional and rational value and I will show all the elements which catch our attention. Then I will provide a questionnaire survey. And I will compare its results with eye tracking survey from Millward Brown agency. This agency carries out neuromarketing research in the Czech Republic.

Med den tekniska utvecklingen inom 3D-skanning det senaste decenniet har användningen av punkmolnsdata ökat signifikant. För att skapa dessa punkmoln används en mängd olika metoder och instrument. Bland annat används ofta fotogrammetri, terrester laserskanning eller mobil laserskanning. Med de nyare mobila skannrarna används oftast en SLAM-algoritm för att kunna korrekt skanna omgivningen samtidigt som skannern förflyttas. Till detta används oftast en IMU som positionerar skannern genom tröghetsnavigering eller kameror för att med triangulering bestämma positionen. Med nya förbättrade algoritmer och utrustning blir systemen hela tiden noggrannare och det utvecklas fler och fler nya system, ofta för specifika användningsområden. Matterport Pro2 3D-kamera som testades i detta projekt är ett sådant system som huvudsakligen utvecklats för att genom skanning, RGB-D och 360°- bilder visualisera och skapa digitala modeller av bostäder. Dessa modeller skapas både i form av punktmoln och meshmodeller. I projektet undersöks hur olika ljusförhållanden påverkar resultatet vid skapande av 3D-modeller med Matterport Pro2 kameran. Uppmätta längder mellan signaler utplacerade i testrummet användes för att kontrollera punktmolnen. Totalt skannades rummet fem gånger vid olika ljussättning varierande från 1 till 800 lux. Avvikelserna i längderna från punktmolnen jämfördes för att avgöra vilket punktmoln som avvek minst från de uppmätta längderna i rummet. Resultatet tyder på att bästa ljussättningen är runt 30 - 60 lux. Ingen skillnad i mätosäkerhet mellan övriga ljusnivåer kunde ses. Utöver det visar avvikelserna också tecken på påtagliga systematiskt fel vilket inte är helt oväntat och har påvisats av en tidigare studie av samma kamera. Detta betyder att kameran behöver kalibreras innan den används för skanning som kräver låg mätosäkerhet. / Due to the technological development within 3D-scanning the last decade usage of pointcloud data has increased significantly. To generate these pointclouds a plethora of methods and instrument are used. Among other photogrammetry, terrestrial laser scanning and mobile laser scanning are commonly used. With the newer mobile scanning systems a SLAM algorithm is usually used for the scanner to correctly scan the surroundings while being moved at the same time. To achieve this a IMU is usually used for positioning or cameras using triangulation. With new algorithms and equipment scanning systems keeps improving. This leads to more and more systems being developed, usually for a specific area of usage. Matterport Pro2 3D-camera which was tested in this project is such a system developed mainly for visualising and creating 3D-models of housing through scanning, RGB-D and 360°-images. These models generated are pointclouds aswell as meshmodels. In this project the effect of different illuminance has on the results when creating 3D-models with the Pro2 camera is tested. Measured distances between targets placed around the testing room were used for checking the point clouds for errors. In total five scans were performed at different illuminance varying from 1 – 800 lux. Deviations between measured distances and point cloud distances were compared to determine which point cloud deviated the least. Results show that an illuminance of about 30 - 60 lux gave the best result. Any significant differences between the other light conditions could not be determined. Furthermore, the results imply there is a systematic error which is not completely unexpected and has been shown in a previous study with the same camera. This means the camera needs a calibration before being used to scan where higher accuracy is needed.

For the purpose of an future machine vision system development in Tyco Electronics Czech s.r.o. I have developed Cognex Designer template. Template will serve as a flexible basis for further development of camera applications on the Cognex VC5 industrial computer. The functionality of the program template has been successfully verified by modifying it to a particular application of the laboratory manual station used to measure the parameters of the manufactured connectors. A camera with lens and lightning was chosen and installed on the station. DIO communication was put into operation between VC5 and PLC system. The application has been calibrated and verified as a measurement system using MSA Type I and Capability study standard methods.

The main theme of the master's thesis is using of thermal camera to measure temperatures in electrical engineering. First are mentioned the physical principles of heat transfer. Then the thesis deals with methods of determining the correct emissivity of the measured object and in the next point with sensors designed for sensing infrared radiation, there is also part dedicated to evaluation software Report Sat Standard, which was used to evaluate the pictures taken with thermal camera SAT-HY 6800. Next part of this work is the measurement of the DC and EC motor with help of thermocamera, which took place in the electric company ATAS Nachod. Attachment to this master's thesis there is animation of EC motor created in Autodesk Inventor.

In this thesis anatomical retinal survey, properties of image data from digital fundus camera and retinal image classification methods are briefly described. The last chapter is devoted to the evaluation of efficiency of retinal vessel classification with automatic methods.
