In the rst chapter, are discussed aspects of the history and Napoleon Bonaparte biography. In the second chapter are addressed notions of Plane Geometry, Linear Algebra, of Rigid Transformation of Complex Numbers and Related Transformations. In the third chapter, statements are presented, generalizations (especially the so-called Barlotti Theorem), properties and applications in exercises. / O presente trabalho aborda o teorema de Napoleão em perspectivas históricas e conceituais, enfocando demonstrações e propriedades. No primeiro capítulo, são abordados aspectos da biogra a de Napoleão Bonaparte. No segundo capítulo são abordadas no- ções de Geometria Plana, de Álgebra Linear, de Transformações Rígidas, de Números Complexos e Transformações A ns. No terceiro capítulo, são apresentadas demonstra ções, generalizações (em especial, o chamado Teorema de Barlotti), propriedades e aplicações em exercícios.

2	Vision based control and landing of Micro aerial vehicles / Visionsbaserad styrning och landning av drönare Karlsson, Christoffer January 2019 (has links) This bachelors thesis presents a vision based control system for the quadrotor aerial vehicle,Crazy ie 2.0, developed by Bitcraze AB. The main goal of this thesis is to design andimplement an o-board control system based on visual input, in order to control the positionand orientation of the vehicle with respect to a single ducial marker. By integrating a cameraand wireless video transmitter onto the MAV platform, we are able to achieve autonomousnavigation and landing in relatively close proximity to the dedicated target location.The control system was developed in the programming language Python and all processing ofthe vision-data take place on an o-board computer. This thesis describes the methods usedfor developing and implementing the control system and a number of experiments have beencarried out in order to determine the performance of the overall vision control system. Withthe proposed method of using ducial markers for calculating the control demands for thequadrotor, we are able to achieve autonomous targeted landing within a radius of 10centimetres away from the target location. / I detta examensarbete presenteras ett visionsbaserat kontrollsystem for dronaren Crazy ie 2.0som har utvecklats av Bitcraze AB. Malet med detta arbete ar att utforma och implementeraett externt kontrollsystem baserat pa data som inhamtas av en kamera for att reglera fordonetsposition och riktning med avseende pa en markor placerad i synfaltet av kameran. Genom attintegrera kameran tillsammans med en tradlos videosandare pa plattformen, visar vi i dennaavhandling att det ar mojligt att astadkomma autonom navigering och landning i narheten avmarkoren.Kontrollsystemet utvecklades i programmeringsspraket Python och all processering avvisions-datan sker pa en extern dator. Metoderna som anvands for att utvecklakontrollsystemet och som beskrivs i denna rapport har testats under ett ertal experiment somvisar pa hur val systemet kan detektera markoren och hur val de olika ingaendekomponenterna samspelar for att kunna utfora den autonoma styrningen. Genom den metodsom presenteras i den har rapporten for att berakna styrsignalerna till dronaren med hjalp avvisuell data, visar vi att det ar mojligt att astadkomma autonom styrning och landning motmalet inom en radie av 10 centimeter. vision control system quadcopter python camera vision based landning crazyflie optical visual odometry odometry transformation ArUco Kalman filter PID marker rigid transformations drone transform control system homogenous transformation ORB detection marker detection Drönare kontroll system kontrollsystem quadcopter quadrocopter kamera vision visionsbaserad styrning landning crazyflie optisk transform homogen transform ORB detektering markör Elektroteknik och elektronik
